BUILT-IN INSTALLATIONS

The appliance is deigned to be built into a new or

existing chimneybreast installation to provide efficient

space heating with both radiant and convected heat.

There must be sufficient space in the fireplace recess to

allow air to circulate around to back, top sides and base

of the appliance.

The example fig 1 shows how your Dovre should be

installed in a chimneybreast recess for chimneybreasts

situated internally and externally.

The recess should be formed using an appropriately

designed raft lintel to support the existing structural

brickwork and chimney. The minimum clearances between

the appliance and walls are illustrated in figs 2 & 3.

PROCEDURE

Prepare the opening ensuring that adequate support

provided

for

the

chimney

and

chimneybreast structure. A raft lintel, to form the top

of the convection chamber, should be constructed.

The lintel should be pre-formed with a clearance

hole of 200mm (for the 1800W series, the clearance

need only be 150mm or 180mm depending on the

diameter of the flue pipe) to allow the connecting

flue pipe to be installed. If the recess is too wide,

reduce the width using 75mm thick building blocks.

Line the top, sides and back of the recess (convection

chamber) using Dovre insulated panels. Fix the

panels to the brickwork (aluminium face outwards)

using masonry nails or other suitable fixings.

If the fireplace is located on an outside wall, install a

standard airbrick or Dovre air control damper (part

number ASI) at floor level. For fireplaces located on

inner walls, it will be necessary to bring an air

supply from under the floor.

AN AIR SUPPLY IS PARTICULARLY IMPORTANT IN

WELL-INSULATED ROOMS.

Stand the appliance in the recess and adjust the

levelling bolts on the bottom of the legs to ensure the

appliance is level and plumb.

Use a length of 316 grade 1mm thick stainless steel

flue pipe or other pipe which complies with Current

Building Regulations for the installation of solid fuel

burning appliances, connected from the flue spigot on

the appliance to the main chimney. See fig 2 page 4.

ENSURE THAT THE APPLIANCE DOES NOT DIRECTLY

SUPPORT THE WEIGHT OF THE MAIN CHIMNEY OR

CHIMNEY LINERS. THE FLUE LINERS MUST BE

SUPPORTED BY INDEPENDENT BRACKETS.

Construct the hearth making sure that the design and

structure

complies

Regulations.

The finished hearth surface (e.g. hearth tiles) should

be approximately 6mm below the bottom of the

doors. See fig. 2 page 4.

Construct the facing wall of the fireplace, using a

lintel to support brickwork / masonry above the

appliance.

NEVER BUILD DIRECTLY ONTO THE APPLIANCE.

50mm thick lightweight building blocks backed

with Dovre insulation panels are ideal for

constructing the facing wall of the convection

chamber. See fig 2 & 3 page 4.

Install air grills, total minimum area 600sq.cm at the

highest point of the convection chamber. Install air

grills minimum area 400sq.cm as close to the floor

level as possible. There is no restriction on the

number of grills used.

Where the fireplace backs onto another room, or is

situated in the corner of the room, backing onto two

rooms, grills can be fitted in the adjacent rooms. In

this case, it will also be necessary to fit a return air

grill in the other room or rooms.

NEVER USE GRILLS MADE FROM PLASTIC OR

existing

OTHER COMBUSTIBLE MATERIALS.

MODELS WITH BACK BOILERS

The model 2000MFR is available with an optional glass

lined boiler suitable for direct or indirect cylinders. The

system must incorporate gravity circuit open to

expansion. Pipework must be a minimum diameter of

28mm and must be installed to rise from the appliance.

IT IS RECOMMENDED THAT A QUALIFIED HEATING

ENGINEER IS USED TO INSTALL HOT WATER MODELS.

The chimney is the key to the successful installation of your

Dovre appliance. If the chimney is in poor condition or of

the wrong design or construction, the performance of the

appliance will be adversely effected and problems will be

experienced with combustion and possible smoke emission

to the room.

PLEASE SEEK THE ADVICE OF A CHIMNEY SPECIALIST IF IN

The chimney should be one of the following types:

Brick built with suitable liner for use with

woodburning and solid fuel appliances.

Twin wall stainless steel approved for use with

woodburning and solid fuel appliances.

Prefabricated "concrete" type systems approved for

use with woodburning and solid fuel appliances.

DO NOT USE FLEXIBLE LINERS DESIGNED FOR USE

ONLY WITH GAS STOVES

MINIMUM 200MM (150MM FOR 1800)

NEVER ALLOW THE APPLIANCE TO CARRY THE

Dry wood (minimum 2 years seasoned), Lignite briquettes

(brown coal), dry peat, Homefire.

Dry wood (minimum 2 years seasoned), Lignite briquettes

(brown coal), dry peat and most manufactured smokeless

fuels.

LIGHTING AND OPERATION

• Place tightly rolled newspaper or firelighters on the grate

of the appliance.

• Place a reasonable quantity of small pieces of dry kindling

wood on top of the newspapers and 3 or 4 pieces of wood

approx. 2.5 to 5cm in diameter on top of the kindling wood.

• Slide the lower and upper air controls to the fully open

position. (1800W is not equipped with upper air controls).

• Open the doors fully and light the front newspaper or

Firelighters with a long taper.

• Immediately after the kindling wood begins to burn,

partly close the doors leaving a distance of 2 - 3cm from the

fully closed position.

• Allow the fire to burn fiercely in order to warm the

chimney as quickly as possible. As soon as the fire is

burning well, add more wood or solid fuel.

• If burning solid fuels, the solid fuel may be placed directly

on the firelighters.

• Ideally your wood should be no more than 10cm diameter.
