• If an external electrical source is utilized, the appliance, when installed, must be electrically grounded in accordance with local codes, or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70, and CSA C22.1, Electrical Code.
• Do not place aftermarket covers on or over Booster Water Heater. Doing so can cause temperature and moisture build-up resulting in premature failure and electrical shock.

WARNING

ELECTRIC SHOCK HAZARD: Use only Genuine Hatco Replacement Parts when service is required. Failure to use Genuine Hatco Replacement Parts will void all warranties and may subject operators of the equipment to hazardous electrical voltage, resulting in electrical shock or burn. Genuine Hatco Replacement Parts are specified to operate safely in the environments in which they are used. Some aftermarket or generic replacement parts do not have the characteristics that will allow them to operate safely in Hatco equipment.

This unit must be serviced by qualified personnel only. Service by unqualified personnel may lead to fire, explosion, electric shock, or burn.

ALWAYS turn OFF power at fused disconnect switch/circuit breaker, shut off gas supply, and allow unit to cool before performing any cleaning, adjustments, or maintenance.

Temperature/pressure protective equipment should not be less than a combination temperature/pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of this equipment and meets the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, CSA ANSI Z21.22 /CSA 4.4. The temperature/pressure relief valve must be marked with a minimum set pressure not to exceed the marked hydrostatic test pressure of the Booster Water Heater as noted on the unit specifications.

FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH CSA ANSI Z21.22/CSA 4.4. Combination pressure and temperature relief valves with extension thermostats must be installed so that the temperature-sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed directly in a tank tapping. Combination pressure and temperature relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9.1 m), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

WARNING

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

Use only copper plumbing material. Non-copper plumbing material may create an unsafe condition.

Units are equipped with a high temperature limit safety switch that will shut off the power if the unit overheats. Contact an Authorized Hatco® Service Agent if the high temperature limit safety switch cannot be reset or continues to trip.

Before performing any maintenance/service, care should be taken that any of the discharged water does not come into contact with the operator or surrounding surfaces. Water can be extremely hot and can cause severe scalding and damage to the property.

If relief valve discharges periodically, do not plug valve. If replacing valve does not stop discharge, contact an Authorized Hatco Service Agent or the Hatco Service Department.

Install booster water heater in a horizontal position with the base parallel to the floor and the inlet connection at the lowest point. Improper installation could create an unsafe condition.

Do not connect booster water heaters to domestic (consumer) dish machines or other domestic utilized equipment. This booster may damage domestic equipment.

This product contains fiberglass, a product known to the state of California to cause cancer, birth defects, or other reproductive harm.

Install booster water heater as close as possible to a commercial dish machine. Employ re-circulation if distance between water heater and dish machine exceeds NSF specifications of five (5) linear feet (1524 mm).

It is essential to recognize that even though a water heater may be properly installed initially and approved, there always exists the possibility that unknowing individuals might alter or change the installation in a manner that would render it unsafe. Therefore, it is important that all safety programs provide some mechanism to assure that these installations are inspected periodically.

This unit has no "user-serviceable" parts. If service is required on this unit, contact an Authorized Hatco Service Agent or contact the Hatco Service Department at 414-671-6350.

CAUTION

BURN HAZARD:

• Water in unit is very hot. Wear protective gloves and proper attire when operating to avoid injury.
- Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters.

Do not use anti-siphon valves or check valves on incoming water line. Damages caused by the use of these valves on unit will not be covered by warranty.

Do not connect Booster Water Heater directly to a boiler or furnace coil or any other uncontrolled temperature source. The Booster Water Heater thermostat could be damaged causing unit to overheat.

Incoming water temperature should be minimum of 85^ F ( 29^ C). Damage to the heater can occur if water is cooler than 85^ F ( 29^ C).

Do not connect an expansion tank of any type to Booster Water Heater water lines.

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

Hatco requires that two temperature/pressure gauges (Hatco P/N 03.01.003.00) be installed to ensure proper operation. Install one in the supply line before the pressure reducing valve and one in the outlet line as close to the Booster Water Heater as possible. This provides a visual check of the water temperature and pressure before and after the water heater.

DO NOT turn on power to the Booster Water Heater until tank has been filled with water and all air has been vented through the dish machine rinse nozzles. Heating elements will burn out in seconds if operated when not immersed in water.

To avoid freezing water damage to the Booster Water Heater when the outside temperature is below 32^ F ( 0^ C), the unit must be left ON and the venting must be protected from migrating cold air.

Failure to drain the heat exchanger prior to exposing it to freezing conditions will damage the heat exchanger and void the warranty.

The use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenylsulfone) in nonmetallic venting systems is prohibited. Covering non-metallic vent pipe and fittings with thermal insulation is also prohibited.

Using or storing chlorine based products on or near the Booster Water Heater may shorten the life of the unit and void the product warranty.

NOTICE

If water supply pressure to the booster inlet is over 20 psi (138 kPa) during flow, install pressure reducing valve with built-in bypass (Hatco P/N 03.02.004.00) for proper operation of dish machine rinse nozzles.

NOTE: The pressure reducing valve must be the type equipped with a high pressure bypass, as supplied by Hatco.

NOTICE

Incoming water supply to Booster Water Heater must be a minimum of 20 psi (1.4 kg/cm2). Water pressure less than 20 psi (1.4 kg/cm2) will decrease operating life of recirculating pump and unit.

NOTE: Product failure caused by incoming water pressure less than 20 psi (1.4 kg/cm2) is not covered under warranty.

Always drain Booster Water Heater with power to the unit off or element burnout could occur.

Use dielectric couplings when connecting dissimilar metals, such as galvanized to copper. This will prevent electrolysis or premature plumbing damage.

Do not back out or loosen any pipe fittings or leaks may occur.

Do not lay unit on the side with the control panel or inlet and outlet pipes. Damage to the unit could occur.

NOTICE

Incoming water in excess of 3 grains of hardness per gallon (GPG) (0.75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to Booster Water Heater(s). Water containing over 3 GPG (0.75 GPL) will decrease efficiency, increase energy use, and reduce the operating life of the unit through increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty.

Units are voltage-specific. Refer to specification label for electrical requirements before beginning installation. Connecting unit to incorrect power supply will void product warranty and may damage unit.

PMG-200

NOTE: Hatco Booster Water Heaters are approved for use with commercial dishmachines only.

NOTE: Refer to the OPTIONS AND ACCESSORIES section for information on available options.

Hatco® Powermite Gas Booster Water Heaters are designed to maintain a water temperature of 180°F (82°C) required for the sanitizing rinse cycle of commercial dishmachines. An inlet water temperature of at least 43°C (110°F) will produce optimum results (See Water Temperature Recovery Table in the SPECIFICATIONS section).

After the necessary power, water, and gas connections are completed, start the unit by turning on the Power I/O (on/off) switch located on the lower front base. The water circulating pump will start at this time. Providing that operating and safety controls are satisfied, the ignition module will begin a 20 second safety pre-purge. Next, it will energize the spark igniter and turn on the gas for the pilot. The igniter will spark for about 90 seconds or until proof of a pilot fire. If there is a confirmed pilot fire and the water temperature is below the setpoint, the unit will go into full burn. The unit will stay in full burn until the desired setpoint temperature is met, then the burner will shut off. During standby periods of limited use, the burner will cycle on only to replace standby water temperature loss. If for some reason the unit did not ignite, there is an automatic five minute delay before the unit attempts to ignite again.

During operation, water enters the Booster Water Heater at the inlet water connection and flows into the stainless steel tank. It then is pumped through the finned tube heat exchanger where it is heated to the proper temperature. The heated water then returns back to the top half of the stainless steel tank for supply to the dishmachine. Water that is not used immediately by the dishmachine is recirculated through the heat exchanger by the water circulating pump.

If the unit overheats above the setpoint temperature, the safety high limit will open, shutting down the burner, locking out the controller, and turning on the alarm pilot light. In order to reset the unit, turn the unit off and depress the reset button on the appropriate high limit switch, the tank high limit is located behind front panel on the left hand side of the vertical control panel. The heat exchanger high limit is located on the front of the heat exchanger. The switches will not reset until the temperature has dropped to a safe level. This unit must remain off for at least 10 seconds before it can be restarted.

NOTA: The temperature control is factory preset at 88^ C ( 190^ F).

NOTA: The water circulating pump will stay on as long as the Power I/O (on/off) switch is in the I (on) position.

NOTE: In the Commonwealth of Massachusetts, Hatco Booster Water Heaters shall be installed by a licensed plumber and gasfitter.

NOTE: The Commonwealth of Massachusetts requires that if a water treatment system is installed in line with the Hatco Booster Water Heaters, a water backflow protector shall also be installed.

NOTE: If a check valve or water backflow protector is installed and cannot be removed, install a back pressure relief valve (Hatco P/N 03.02.039.00) set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the Booster Water Heater. Discharge must be to open site drain.

For the most effective operation, install the Hatco Gas Booster Water Heater as close as possible to the dishmachine.

NOTE: Employ external recirculation if distance between booster and dishmachine exceeds the NSF specification of 5' (1.5 m).

The Booster Water Heater must not be installed directly on carpeting, but on top of a metal, wood (or equivalent) panel extending beyond the full width and depth of the heater by at least 3" (76 mm) in any direction or, if the heater is installed in an alcove, the entire floor must be covered by the panel. The panel must be strong enough to carry the weight of the Booster Water Heater when full of water.

Adequate front clearance is required to allow for accessibility to the control compartment.

The Booster Water Heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the heater or to lower floors of the structure. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the Booster Water Heater. The pan must not restrict combustion air flow.

Combustion/Ventilation Air

WARNING

The flow of air to the heater for combustion and ventilation MUST NOT be obstructed. Air vents on the bottom and side of the unit should never be blocked. All panels should be in place during normal operation for optimal performance and safety.

This unit is designed to vent to the outside or into an open Equipment Hood, and is intended for commercial food service water heating only. NOT FOR RESIDENTIAL USE. See “Venting Installation” in the INSTALLATION section of this manual.

Flue gases exit top side or back of this unit and must not be obstructed, specified clearances must be maintained for safe operation. See "Venting Installation" in the INSTALLATION section for vent piping alternatives.

CAUTION

The use of cellular core PVC (ASTM F891), cellular core CPVC, or Radel® (polyphenylsulfone) in nonmetallic venting systems is prohibited. Covering non-metallic vent pipe and fittings with thermal insulation is also prohibited.

The Booster Water Heater must be located in an area that allows for an adequate supply of air for proper combustion and ventilation in accordance with Section 5.3 and 7.2.2 of the National Fuel Gas Code NFPA54/ANSI Z223.1 or applicable provisions of the local building codes. Only a single booster appliance may be installed in this manner. Installations under the jurisdiction of Canadian CSA-B149.1, Natural Gas and Propane Installation Code, require a gas interlock tied into the ventilation hood system.

High Altitude Installation and Operation

Atmospheric conditions at elevations above 2000 ft. (610 m) have an effect on the performance of most gas fired products. For this reason, historical models for altitude de-rating were developed for gas appliances with atmospheric burners. The National Fuel Gas Code, ANSI Z223.1, is an accepted model that requires a de-rating of 4% per 1000 ft. (305 m) elevation when no testing to the contrary exists for that product. This could require modifying the equipment and adjusting settings in the field to achieve de-rating. Testing has shown this to be a very conservative approach.

Manufacturers discourage unnecessary field adjustments in order to maintain a level of performance and quality designed into the product. For these and other reasons, testing was underwritten through CSA International to verify an improved satisfactory performance with little or no modification to effect input rate or control. The following text and charts are a result of this testing and should be used during application sizing and installation.

- The PMG-100 can operate at better levels than ANSI Z223.1 without manifold pressure setting adjustments or orifice changes up to the 8500 ft. (2593 m) elevation for both natural gas and liquid propane gas units. Above this level only a slight decrease in manifold pressure may be needed to meet the approved BTU rate. This is shown in the Altitude Summary chart. Also, note that GPH capacity will be reduced and a guideline is given as to the percent of sea level capacity expected.

For Canadian installations between 2000-4500 feet (610-1370 m) de-rate unit by 10% to 94,500 BTU.

- The PMG-200 will require orifice changes at levels shown in the Altitude Summary chart. This follows the 4% derating scheme outlined in ANSI Z223.1 for both natural gas and liquid propane gas. Also note that the GPH capacity will be reduced and a guideline is given as to the percent of sea level capacity expected.

For Canadian installations between 2000-4500 feet (610-1370 m) de-rate unit by 10% to 175,500 BTU.

Orifice Kits for altitude installations may be ordered through Hatco Customer Service. Please call for orifice sizing information.

WARNING

Do not connect booster water heaters to domestic (consumer) dish machines or other domestic utilized equipment. This booster may damage domestic equipment.

Do not connect an expansion tank of any type to Booster Water Heater water lines.

Use only copper plumbing material. Non-copper plumbing material may create an unsafe condition.

CAUTION

Do not connect Booster Water Heater directly to a boiler or furnace coil or any other uncontrolled temperature source. The Booster Water Heater thermostat could be damaged causing unit to overheat.

NOTE: If a check valve or water backflow protector is installed and cannot be removed install a back pressure relief valve, Hatco P/N 03.02.039.00, set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the Booster Water Heater. Discharge must be to open site drain.

Pressure And Temperature Relief Valves

For protection against excessive pressures and temperatures in the Booster Water Heater, install temperature and pressure protective equipment by local codes. Hatco supplies valves constructed with brass working parts and heat resistant silicone seat discs for all Booster Water Heater models.

WARNING

Temperature/pressure protective equipment should not be less than a combination temperature/pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of this equipment and meets the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, CSA AN SI Z21.22 /CSA 4.4. The temperature/ pressure relief valve must be marked with a minimum set pressure not to exceed the marked hydrostatic test pressure of the Booster Water Heater as noted on the unit specifications.

WARNING

FOR INSTALLING PRESSURE AND TEMPERATURE RELIEF VALVES IN ACCORDANCE WITH CSA ANSI Z21.22/CSA 4.4. Combination pressure and temperature relief valves with extension thermostats must be installed so that the temperature-sensing element is immersed in the water within the top 6" (152 mm) of the tank. They must be installed directly in a tank tapping. Combination pressure and temperature relief valves that do not have extension elements must be mounted directly in a tank tapping located within the top 6" (152 mm) of the tank, and shall be adequately insulated and located so as to assure isolation from ambient conditions that are not indicative of stored water temperature. TO AVOID WATER DAMAGE OR SCALDING DUE TO VALVE OPERATION, DRAIN PIPE MUST BE CONNECTED TO VALVE OUTLET AND RUN TO A SAFE PLACE OF DISPOSAL. Discharge line must be as short as possible and be the same size as the valve discharge connection throughout its entire length. Drain line must pitch downward from the valve and must terminate between 1-1/2" (38 mm) and 6" (152 mm) above the floor drain where any discharge will be clearly visible. The drain line shall terminate plain, not threaded, with material serviceable for temperatures up to 250°F (121°C) or greater. Excessive length, over 30' (9.1 m), or use of more than four elbows can cause a restriction and reduce the discharge capacity of the valve. No shut-off valve shall be installed between the relief valve and tank, or in the drain line. Valve lever must be tripped periodically to assure that waterways are clear. This device is designated for emergency safety relief and shall not be used as an operating control. The valves are set to relieve at 150 psi (1034 kPa) or when water temperature reaches 210°F (99°C). Read tag on valve for additional information.

CAUTION

BURN HAZARD: Valves supplied by Hatco are designed for high temperature commercial operation. Do not substitute Hatco valves with valves designed for domestic water heaters.

Do not use an anti-siphon or check valves on incoming water line. Damages caused by the use of these valves on unit will not be covered by warranty.

Temperature/Pressure Gauges

Hatco ^® requires a temperature/pressure gauge be installed in both the inlet and outlet lines to the Booster Water Heater. These gauges provide an instant visual check of the water temperature and pressure entering and leaving the Booster Water Heater. The visual check is helpful in eliminating unnecessary service calls.

Install the temperature sensing bulb in the water system. See the illustrations below for methods of installation.

Recommended Temperature/Pressure Gauge Installation

Temperature/ pressure gauge with 1/2" pipe thread Center bottom of sensor in copper pipe 3/4" nominal copper pipe 1/2" copper female fitting adapter 3/4" x 1/2" x 3/4" copper tee Temperature sensing element

Alternate Temperature/Pressure Gauge Installation

CAUTION

Hatco requires that two temperature/pressure gauges (Hatco P/N 03.01.003.00) be installed to ensure proper operation. Install one in the supply line before the pressure reducing valve and one in the outlet line as close to the Booster Water Heater as possible. This provides a visual check of the water temperature and pressure before and after the water heater.

Pressure Reducing Valve

Proper operation of most dishmachine rinse nozzles require available water flow pressure at the nozzle to be 20 psi.

If water pressure available to the Booster Water Heater inlet is over 20 psi, a pressure reducing valve with bypass must be installed in the hot water supply line to the Booster Water Heater.

The valve supplied by Hatco has a built-in high pressure bypass which prevents excessive pressure build-up as the booster heats up. CAUTION! Pressure regulating valve must have a built-in high pressure bypass.

Blended Phosphate Water Treatment System

Hatco requires that the Blended Phosphate Water Treatment System supplied be installed with unions on the incoming 3/4" water supply line after the pressure reducing valve and before the Booster Water Heater.

Cartridges supplied have a usage rating of 100,000 gallons of water. To ensure proper operation the cartridges must be replaced when expired.

NOTE: Product failure caused by liming or sediment buildup is not covered under warranty.

NOTE: The Commonwealth of Massachusetts requires that if a water treatment system is installed in line with the Hatco Booster Water Heaters, a water backflow protector shall also be installed.

NOTE: If a check valve or water backflow protector is installed and cannot be removed, install a back pressure relief valve (Hatco P/N 03.02.039.00) set at 125 psi (862 kPa) on the incoming line between the pressure reducing valve and the inlet to the Booster Water Heater. Discharge must be to open site drain.

Plumbing Connections

NOTICE

Incoming water supply to Booster Water Heater must be a minimum of 20 psi (1.4 kg/cm2). Water pressure less than 20 psi (1.4 kg/cm2) will decrease operating life of recirculating pump and unit.

NOTE: Product failure caused by incoming water pressure less than 20 psi (1.4 kg/cm2) is not covered under warranty

Do not back out or loosen any pipe fittings or leaks may occur.

Incoming water in excess of 3 grains of hardness per gallon (GPG) (0.75 grains of hardness per liter [GPL]) must be treated and softened before being supplied to Booster Water Heater(s). Water containing over 3 GPG (0.75 GPL) will decrease efficiency, increase energy use, and reduce the operating life of the unit through increased lime build-up. Product failure caused by liming or sediment buildup is not covered under warranty.

Inlet

Hatco Booster Water Heaters are designed to be connected with 3/4" pipe at the inlet pipe from the primary water heater. Water temperature from the primary water heater must be at least 110°F (43°C) and should not exceed 160°F (71°C). Minimum temperature differential between the inlet and outlet temperature must never be less than 20°F (11°C).

Inlet line must be installed with a shut-off valve, a full open gate or ball type valve, a 3/4" union, together with the blended phosphate water treatment system, pressure reducing valve set at 20 psi (1.4 kg/cm2) flow pressure and a temperature/pressure gauge supplied by Hatco.

NOTE: Do not run a cold ground water line to the Booster Water Heater.

NOTE: Be sure water flows through the pressure reducing valve in the proper direction. Check the directional arrow. Valve will reduce pressure only during flow conditions.

A 3/4" union fitting and a drain valve also must be installed to allow for easy servicing.

The temperature/pressure relief valve must be installed into one of two locations on the heater: either the right side or the back of the unit. See the "Plumbing Connections" illustrations in this section for exact locations.

To prevent water leakage and damage to the unit, the location for the temperature/pressure relief valve that is not used must be plugged. (One plug is supplied by Hatco with the heater.) Both temperature/pressure fittings must not be plugged.

NOTE: The Commonwealth of Massachusetts requires that if a water treatment system is installed in line with the Hatco Booster Water Heaters, a water backflow protector shall also be installed.

Outlet

Using a 3/4" union and piping, connect the Booster Water Heater water outlet to the dishmachine sanitizing rinse pipe connection.

NOTE: Be certain the connection is made to the final rinse and not to the wash tank.

Install a temperature/pressure gauge in outlet line. Water temperature at outlet should be 180^ F ( 82^ C).

NOTE: The temperature sensing element must be in water stream.

Shock Absorber

In areas of high water pressure, Hatco recommends a shock absorber be installed in the outlet line as close as possible to the dishmachine. The shock absorber softens the water hammer caused by automatic dishmachine valves.

NOTE: Fill Booster Water Heater with water to test for installation leaks. Leave the water in booster to prevent pump damage in the event the electrician should apply power.

Venting Installation

The PMG-100 and PMG-200 may be vented by two methods, both of which have been tested for compliance with national safety standards for gas water heaters. Whichever method is used must comply with local codes. The installation of the venting system must comply with local codes and in the absence of local codes, in accordance with the National Fuel Gas Code and the guidelines in this manual. Before installing any method of venting, contact the local code authority of your gas supplier to make sure that the final installation will be acceptable to the authorities having jurisdiction.

The proper method of venting a power vented gas appliance is too complicated to cover in this manual and is explained in detail in the National Fuel Gas Code. Before installing the venting system, the person or agency making the installation must be familiar and experienced with the guidelines of the National Fuel Gas Code.

The temperature of the flue gases from this booster water heater operates at approximately 225^ F to 275^ F ( 107^ C to 135^ C).

The two methods that have been tested for compliance with the national safety standards are:

1. The first method of venting permits the connection of 4" (102 mm) diameter, AL 29-4C1 stainless steel vent pipe. Use only Duravent "FasNSeal" products currently listed to ANSI/UL 1738 by a nationally recognized testing agency for category III venting. The maximum combined horizontal vent length must not exceed a length of 40 feet (12 m) [each sweep elbow is the equivalent of 5' (1.5 m) of straight pipe and a standard right elbow is the equivalent of 10' (3 m)]. Venting shall be installed per vent pipe manufacturer's instructions. The venting may be done in such a way that the exhaust products are:

a. Conveyed to another area in the kitchen such as under a ventilator or near an exhaust fan (both of which exhaust outdoors).
When using this method the booster water heater must be electrically interlocked with the vent hood to prevent operation if the vent hood is not operating.
The termination end must be placed so that it vents above the bottom of the hood skirt. Do not penetrate the filter with the vent.
b. Horizontally vented through an outside wall directly to the outdoors. See the additional instructions and illustration below.
c. Exhausted into a vertical masonry chimney that has a listed steel liner installed in the chimney. Locate appliance as close as practicable to a chimney or gas vent. Because of the low flue gas temperature, do not vent into an unlined or masonry lined chimney designed to burn solid fuel. Note that all venting into a vertical chimney of any type must comply with the horizontal and vertical ratios and sizing requirements that are detailed in the National Fuel Gas Code.
d. For Model PMG-100 only: Vented vertically using type B vent pipe that is 5" (127 mm) in diameter provided the termination above the roof uses a listed wind cap.

Vent Pipe should not penetrate filter. Vent Hood

Venting Through Typical Exhaust System

1. The second method of venting is to directly exhaust the flue products into the kitchen work area provided the size and installation of the open room meet the requirements of the National Fuel Gas Code [ANSI Z223.1 or NFPA bulletin #54]. A portion of the 1996 code is as follows.

Excerpt From ANSIZ223.1/NFPA #54

7.2.1 Connection To Venting Systems. Excerpt as permitted in 7.2.2 through 7.2.6, all gas utilization equipment shall be connected to venting systems.
7.2.2 Equipment Not Required To Be Vented. A single booster-type [automatic instantaneous] water heater, when designed and used a rinse requirements of a dishmachine, provided that the equipment is installed, with the draft hood in place and unaltered, if a draft hood is required in a commercial kitchen having a mechanical exhaust system. Where installed in this manner, the draft hood shall not be less than 36" (91 cm) vertically and 6" (15 cm) horizontally from any surface other than the equipment.

Where any or all of this equipment is installed so the aggregate input rating exceeds 20 BTU per hr per cu ft (207 watts per m3) of room space in which it is installed, one or more shall be provided with venting systems or other approved means for removing the vent gases to the outside atmosphere so the aggregate input rating of the remaining unvented equipment does not exceed the 20 BTU per hr per cu ft (207 watts per m3) figure. Where the room or space in which the equipment is installed is directly connected to another room or space by a doorway, archway, or other opening of comparable size that cannot be closed, the volume of adjacent room or space shall be permitted to be included in the calculation.

CAUTION

To avoid freezing water damage to the Booster Water Heater when the outside temperature is below 32^ F ( 0^ C), the unit must be left ON and the venting must be protected from migrating cold air.

General Notes On Venting:

• The appliance shall have dedicated venting and not share common or multi-story flue configurations.
• Whenever a vent pipe goes through a combustible wall, the clearance between the vent material and the combustible material must be in accordance with the listing requirements of the vent system chosen. See the vent manufacturer's instructions.
• All horizontal runs of vent pipe must be supported at every elbow and every 3' (1 m) to prevent sagging.
• All horizontals must have an upward pitch of at least 1/4" per foot.
• Right angle adapter is provided to minimize radius of initial bend toward flue piping required for tight quarters.

NOTE: Right angle duct outlet may be installed with duct exiting up, to the left, or to the right. Do NOT install with duct exiting down.

• When venting through a side wall to the outdoors the following must be observed:
• A vent termination [Tee Fitting] must be used that is positioned with the backside of the TEE at least 12" (305 mm) from the exterior wall.
• The vent termination must be away from areas where the general public will walk or vehicle may damage the vent cap.
• The cap must be at least 3' (1 m) above any forced inlet openings [into the building] that are within 10' (3 m) of the cap.
• The cap must be one foot above any windows, doors or other openings into the building.
• The cap must be 4' (1.2 m) horizontally from any doors, windows, etc.
• The cap must be at least 7' (2 m) above any public walkway.
• The bottom of the cap must be at least 1' (0.3 m) above ground and possibly higher if the snow accumulation normally exceeds 1' (0.3 m).
• The cap should be positioned such that any condensate that drips from the cap will not damage plants, shrubs or onto other equipment located on the outside of the restaurant.
• The cap should be positioned so that condensate that drips from the cap will not allow the water to accumulate on walkways or other areas, which may freeze and cause an accident.

2. The recirculating water pump motor is permanently lubricated and requires no other maintenance.
3. Visually observe and inspect the burner and pilot flame every six months. When the burner is operating properly, a clean blue flame will be visible. Depending on the condition of the kitchen environment, the burner may need to be cleaned of lint or grease-laden dust. If any problems are apparent, discontinue use of the heater and contact the Hatco Corporation or your authorized service agent.

Broad Blue Outer Flame Light Blue Inner Cone Slotted Burner Element

• The flame during full burn is a broad blue color. An inner cone slightly lighter in color will also be visible.
• The flame should not be rising off of the face of the burner element.
• Yellow tipped flames suggest a need for adjustment or cleaning of the burner assembly.

Gas Flame

1. Visually observe and inspect the heat exchanger and exhaust blower fan. Depending on the condition of the kitchen environment, the heat exchanger and fan may need to be cleaned of lint or grease laden dust. If any problems are apparent, discontinue use of the heater and contact the Hatco Corporation or your authorized service agent.

2. Once a month, check and clean (if necessary) all air inlet holes on the side or back of the unit.

3. The front access panel should be removed and all components visually inspected at least twice a year. Check for evidence of chafing or heat damage to any wiring or components. Check also for any signs of water leakage at any of the plumbing connections. If there are signs of any damage or leakage contact the Hatco Corporation or your authorized service agent.

4. The relief valve should be manually operated at least once a year to ensure proper operation.

WARNING

Before performing any maintenance/service, care should be taken that any of the discharged water does not come into contact with the operator or surrounding surfaces. Water can be extremely hot and can cause severe scalding and damage to the property.

If relief valve discharges periodically, do not plug valve. If replacing valve does not stop discharge, contact an Authorized Hatco Service Agent or the Hatco Service Department.
