Installation requirements

General

The appliance must be connected tightly to a well-functioning chimney.

For the connection measurements: see the appendix "Technical data".

Ask the fire brigade and/or your insurance company about any specific requirements and regulations.

Flue or chimney

The flue or chimney is needed for:

Disposing of the combustion gases through natural draught.
The warm air in the flue or chimney is lighter than the outside air so it rises.
The intake of air, needed for the combustion of fuel in the appliance.

open A poorly functioning flue or chimney can cause smokers to escape into the room when the door is opened.
mamage caused by smoke emissions into the room is not covered by the warranty.

Do not connect multiple appliances (such as a boiler for central heating) to the same flue, unless local or national regulations allow this.

Ask your installer for advice regarding the flue. Refer to the European norm EN13384 for a correct calculation for the flue.

The flue must satisfy the following requirements:

The flue or chimney must be made of fire resistance material, preferably ceramics or stainless steel.
The flue or chimney must be airtight and well cleaned and guarantee sufficient draught.

i

A draught/vaccuum of 15 - 20 Pa during normal operation is ideal.

Starting from the flue spigot, the flue must run a vertically as possible. Changes in direction and horizontal pieces disrupt the outward flow of combustion gases and may cause the deposit of soot.

DOVRE 750GM - Flue or chimney - 1

The interior measurements should not be too big prevent the combustion gases from cooling down too much, thereby reducing the draught.
The flue or chimney must ideally have the same diameter as the connection collar.

i

For the nominal diameter: see the appendix "Technical data". If the smoke channel is well insulated, the diameter may be slightly bigger (up to 2x the section of the connection collar)

To good combustion, the appliance needs air (oxygen). That air is supplied via adjustable air inlets from the area where the appliance is installed.

The combustion will be incomplete in case of insufficient ventilation, which results in toxic gases being produced and spread through the area.

The section (area) of the smoke channel must constant. Wider segments and (in particular) narrower segments disrupt the outward flow of combustion gases.
- When using a cover plate or exhaust hood: mal- sure that the cover does not restrict the flue out and that the cap does not impede the outward of combustion gases.
The chimney must end in a zone that is not affected by surrounding buildings, adjacent trees, other obstacles.
The chimney part outside the house must be insulated.
The chimney must be at least 4 metres high.
As a rule of thumb: 60cm above the ridge of the roof.
If the ridge of the roof is more than 3 metres away from the flue: stick to the measurements in the following figure. A = the highest point of the roof within a distance of 3 metres.

As a rule of thumb, the air supply should be 5.5cm^2 /kW Extra ventilation is needed when:

The appliance is in an area that is well insulated.
There is mechanical ventilation, for example a central extraction system or an extraction hood in an open kitchen.

You can provide extra ventilation by having a flow ventilation louvre installed in the outside wall.

Make sure that other air consuming appliances (such as tumble-driers, other heating appliances or a bath room fan) have their own supply of outside air, or are switched off when you use the appliance.

Floor and walls

The floor on which the appliance is placed must sufficient load bearing capacity. For the appliance weight: see the appendix "Technical data".

Advice for use

DOVRE 750GM - Advice for use - 1

Never burn wood with an open door.

DOVRE 750GM - Advice for use - 2

Regularly burn wood with intense roaring

Removing ashes

After the brown coal briquettes and anthracite coal has been burnt, a relatively large amount of ash is left. Moreover, remove any excess ash frequently.

If you frequently have low intensity fires, tar and creosote may be deposited in the chimney. Tar and creosote are highly combustible substances. Thicker layers of these substances might catch fire when the temperature in the chimney increases suddenly and steeply. Therefore it is necessary for the fire to regularly burn very intensely, so that layers of tar and creosote disappear.

Low intensity fires also cause tar deposits on the stove window and door.

When the outside temperature is not very low it is better to burn wood intensely for a few hours instead of having a low intensity fire for long period of time.

After the wood has been burnt, a relatively small amount of ashes is left over. This bed of ashes is a good insulating layer for the bottom of the fire compartment and improves combustion. Therefore, you can leave a thin layer of ashes on the bottom of the fire compartment.

However, the air supply through the bottom of the fire compartment must not be impeded and no ash should be allowed to accumulate behind a cast iron inner plate. Therefore, remove any excess ash frequently.

The ash should never reach the underside of the grate.
MyThis will cause the grate to overheat and be damaged.

  1. Open the ash door of the appliance.

Control the air supply with the secondary air inlet.

DOVRE 750GM - Removing ashes - 1

The secondary air inlet not only supplies air to

the fire but to the glass as well, so that it does not get dirty so quickly.

  1. With appliance 750GH: remove the ash removal port and use the supplied scraper to sweep the excess ash into the ash pan..

Remove the ash pan using the "cold hand" provided and empty the ash pan; see next figure.

  • Open the primary air inlet for the time being if the air supply by the secondary air inlet is inadequate or if you want to fan the fire.
    It is better to add a small amount of logs regularly than to add many logs at the same time.
    Regularly adding small amounts of brown coal briquettes or anthracite coal is better than adding a large amount of brown coal briquettes or anthracite coal at once.

Extinguishing the fire

substances will be produced and released. Therefore,

let the fire go out naturally. Keep an eye on the until it has gone out. When the fire has died completely, all air inlets can be closed.

Fog and mist

Fog and mist hinder the flow of flue gases through the flue. Smoke can blow back and cause a stench. If it is not strictly necessary, it is better not to use the stove in foggy and misty weather.

Solving problems

Refer to the appendix "Diagnostic diagram" to solve any problems in using the appliance.

Maintenance

Follow the maintenance instructions in this chapter to keep the appliance in good condition.

Chimney

In many countries, people are legally required to have their chimney checked and maintained.

DOVRE 750GM - Chimney - 1

The insulating vermiculite inner plates may develop hairline cracks, but that does not affect their performance adversely.

DOVRE 750GM - Chimney - 2

Cast-iron inner plates go a long way if you frequently remove the ash that may pile up behind them. If accumulated ash behind a cast-iron plate is not removed, the plate cannot dissipate the heat anymore to its surroundings and that may cause the plate to warp or crack.

DOVRE 750GM - Chimney - 3

Never use the appliance without the fireresistant inner plates.

Removing the baffle plate

At the beginning of the heating season: have the chimney swept by an expert.

The baffle plate is secured with a bolt located between the rear connection and the secondary air duct. The

During the heating season and after the chimney has not been used for a long time: have the chimney checked for soot deposits.

bolt is fixed to the baffle plate.

After the heating season: seal off the chimney with a ball of paper.

  1. Remove the nut on the rear side; see the following figure.

Cleaning and maintenance

DOVRE 750GM - Cleaning and maintenance - 1

Do not clean the appliance when it is still warm.

Clean the exterior of the appliance with a dry lint-free cloth.

At the end of the heating season, you can clean the interior of the appliance thoroughly:

If necessary, first remove the fire-resistant inner plates.
If necessary, clean the air supply ducts.
- Remove the baffle plate at the top of the applian and clean it. See the chapter "Installation" for instructions on removing and installing the baffle plate.

DOVRE 750GM - Cleaning and maintenance - 2

Checking fire-resistant inner plates

The fire-resistant inner plates are consumables and subject to wear. Check the fire-resistant inner plates frequently and replace them when necessary.

  1. Pull the baffle plate forwards so that the bolt comes free from the rear side.
  2. Remove the baffle plate via the front door.

See the chapter "Installation" for instructions on removing and installing the inner plates.

Cleaning glass

  • Dirt clings less easily to well-cleaned glass. Proceed as follows:

  • Remove dust and loose soot with a dry cloth.

  • Clean the glass with stove window cleaner:

a. Apply stove window cleaner to a kitchen sponge, rub down the entire glass surface give the cleaning agent time to react.
b. Remove the dirt with a moist cloth or kitchen tissue.

  1. Clean the glass again with a normal glass clean product.
  2. Rub the glass clean with a dry cloth or kitchen tissue.

Do not use abrasive or aggressive products to clean the glass.
Wear household gloves to protect your hands.

If the glass in the appliance is broken or cracked, it must be replaced before you can use the appliance again.
Make sure that no stove window cleaner runs between the glass and the cast-iron door.

Maintaining enamelled fire

Never clean the appliance when it is still hot. The enamelled surface of the fire can be cleaned most effectively with a mild green soap and lukewarm

water. Use as little water as possible, rub the surface

dry and prevent the formation of rust. Wire wool or Check that the door is properly closed and adjust the other abrasives should never be used. Never placeacking cam as necessary.

kettle directly onto an enamelled fire; use a stand and

prevent damage from occurring.

Lubrication

Although cast-iron is slightly self-lubricating, you will still have to lubricate moving parts frequently.

Lubricate the moving parts (such as guide systems, hinge pins, latches and air slides) with heat resistant grease that is available in the specialist trade.

Touching up damaged paint

dSmall areas of damaged paint finish can be touched up with a spraying can of special heat-resistant paint to finish available from your supplier.

Touching up the enamelled surface

Enamelling is a process carried out by traditional and methods, meaning that it is possible that small colour differences and damage may occur. The appliances undergo a visual inspection in the factory, that is to say, the inspector looks at the surface for a period of 10 seconds from a distance of 1 metre.

Any damage that does not stand out is regarded as OK. A special heat-resistant paint is supplied along with the apparatus, with which minor damage caused during transport can be touched up.

Apply the heat-resistant paint in thin layers and leave to dry well before using the appliance.

Checking the seal

Check whether the sealing rope of the door is still in good condition and works well. The sealing rope is subject to wear and needs to be replaced in time.
Check the appliance for air leaks. Close any chinks with stove sealant.
Let the sealant harden fully before you start a fire in the appliance, because otherwise any moisture in the sealant will form bubbles in the sealant and cause a new air leak.

Re-adjusting the locking cam

Check that the door is properly closed and adjust the locking cam as necessary.

  1. Slide the heat shield up and lift up the under side of the heat shield from the positioning tabs on the side wall of the appliance; see following figure.

Fire in appliance is too intense, is hard to adjust
Deposit on the glass
Possible cause Possiblesolution
Insufficient draughtA cold flue usuallyfails to create sufficient draught. Follow the instructions for lighting in the "Use" chapter; open a window.
Wood too damp Use wood with no moremore than 20% moisture.
Pieces of wood too bigUse smallpieces of kindling. Use split logs no larger than 30 cm in circumference.
Wood stacked up incorrectlyStackup the wood in a way that allows an adequate air flow between the logs (open stacking, see "Burning wood")
Chimney does not work properlyCheck whether the chimney meets the requirements: at least 4 metres high, right diameter, well insulated, smooth inside, not too many bends, no obstructions in chimney (bird'snest, too much soot deposit), hermetically tight (no chinks).
Chimney stack incorrect Sufficiently highhigh above the roof, no obstacles in its vicinity
Air inlets set incorrectly Open the airinletscompletely.
Appliance connected to chimney incorrectlyConnection should be hermetically tight.
Vacuum in area where appliance is installedSwitch off extraction systems.
Insufficient supply of fresh airProvide an adequate air supply; if necessary use connection to outside air.
Adverse weather conditions? Inversion (reversed air flow in chimney because of a high outside temperature) extreme wind velocitiesWe recommend you don't use the appliance in the case of inversion. Install an extra hood on the flue to increase the draught if need be.
Draught in the living roomAvoid draught in the living room, do not place the appliance near a door or heating air ducts.
Flames touch the glassMake sure the wood does not lie too close to the glass. Slide the primary air inlet cover closer to the "Closed" position.
Appliance isleaking air Check the door seals and the appliance joints.
