Frequently Asked Questions - ECO2S KFS2415-1-2S1-ECM KING

How do I install the furnace?

The furnace can be installed in vertical upflow, downflow, or horizontal position. For downflow, the Combustible Floor Base Accessory must be used. Ensure at least 1 inch clearance. Refer to the installation instructions for duct connections and electrical wiring.

What are the required clearances?

King furnaces require a minimum of 1 inch clearance for compact, space-saving installations.

How do I connect the thermostat?

Connect the thermostat to terminals R (24 VAC) and W for heating, and to R and G for cooling (fan only). For two-stage models, use terminals W1 and W2. A jumper wire from W1 to W2 may be needed for single-stage thermostats.

What is the heat anticipator setting?

For models KFS5 through KFS13, set the thermostat heat anticipator to 0.4 amps. For models KFS20 through KFS35, set it to 0.8 amps (or 8 amps? Actually 0.8 amps per sequencer). Adjust according to the number of sequencers.

Why does the furnace not start?

Possible causes: circuit breaker off, 24V transformer burned out, loose wire connections, or thermostat issues. Check that all circuit breakers are ON, and inspect wiring. Also ensure the thermostat is set to heat and the temperature is below the set point.

What filter size does the furnace use?

The furnace uses a 1-inch thick, 16-inch by 20-inch air filter. Replace it several times a year or when dirty.

Can the furnace be used with a cooling unit?

Yes, the furnace can be equipped with a cooling coil for summer cooling. Use a heat/cool thermostat and set the fan switch appropriately. For cooling, set the thermostat to COOL and the fan to ON.

What is the sequence of operation?

When the thermostat calls for heat, after about 30 seconds the first heating element and blower turn on. Subsequent elements turn on at 30-second intervals. When satisfied, the elements turn off in reverse order.

How do I set the blower speed?

The motor has three speed taps: red (low), blue (medium), and black (high). Connect the desired speed wire to the fan relay. Refer to the airflow delivery chart for CFM at different static pressures.

What should I do if the furnace cycles on high limit?

This may indicate dirty ducts, a dirty air filter, or a defective limit control. Clean or replace the filter, check ducts for blockages, and if the problem persists, replace the limit control. Also check that the manual reset button (if equipped) is not tripped.

Installation Instructions

KF and KFS Series

KING furnaces can be installed with a minimum of 1 inch clearance for compact, space saving installations in either vertical upflow, downflow or horizontal position.

When installed in the downtown position, the Combustible Floor Base Accessory must be used.

CHECK furnace to be sure blower wheel is free-turning, and that element assemblies are in place. Be sure titer is in proper position and not tom or damaged.

NOTE: the attached Underwriters Laboratories' label pertains to the furnace only. It does not cover any air cooler, condensing unit or air cleaner, which may be used with the furnace. The optional COU cabinets are designed for slip in addition of an evaporator coil at a later date. Approval of the complete system of air conditioning requires compliance with local ones.

UL

FIELD WIRING: King furnaces come equipped with 60 amp circuit breakers installed for protection of the furnace internal wiring only. They also serve as a connection means when required. A 240 volt single phase circuit must be brought to each circuit breaker in the furnace as shown in the wiring diagram. The terminals are identified as L1-L2, L3-4, L5-6 and L7-L8. The KW size of the furnace determines how many circuits are required. The furnace power and electrical rating table indicates how many circuits each model furnace requires, the size of the branch circuit protection at the distribution panel and the wire size required from distribution panel to the furnace. If there is any questions consult your local and national electric codes. All wiring used must be approved for 75°. NOTE: no wire may have more than 180 VAC potential to ground. This must be checked on installation to avoid motor damage. Unit must be grounded by connection of grounding wire from the distribution panel to the terminal provided in furnace. When the line voltage terminal block option is specified for single strike, wire wiring diagram for wire size and circuit protection requirements.

1. Your King electric turbines has been designed to distribute healed air to your living quarters when connected to appropriate ducting.

2. On models KFS & larger, your furnace operates under command of a low voltage wall thermostat.

3. Horials KFS5 through KFS13 enjoy one sequencer relay and thus the thermosat heat antiisperator should be set at 0.4.

4. Records KESPO, then KESSS company two thermal relays, thus the thermostat heat anticipator should be set at 0.8.

1. With the thermostel set at 70°F and the temperature drops to about 69°F, the thermostel's internal switch closes its contacts. About 30

CONTROL WIRING: Connect thermostat to terminals R and W for treating, and to R and G for cool air only. This can be done with a single stage heat cool thermostat or a single stage heat only thermostat and a separate fan only switch to control the fan relay (optional) installed on furnaces. Some models of furnace have two stage operation (optional) and are provided with terminals W1 and W2. If a single stage thermostat is used if should be connected to terminals R and W1 and a fumor wire installed form terminals W1 to W2; see enclosed control circuit wiring diagram. Some models of furnace have the 24 VAC power available between terminal C and R for use with external air conditioning blower relay option.

OPERATION: When control thermostat is turned up to demand heat the blower and heating elements should be energized. Furnaces with sequences installed will have up to 30 seconds delay in start-up. Heat-cool thermostats when turned to cool position should bring on the blower only for cooling air.
