ASSEMBLY

If the leg extensions are required to be fitted, carefully lay stove on

its back. It will be helpful to lay the stove on two wooden battens.

Remove the wooden pallet.

Fit the leg extension (part no 522110) sections using the large

black washers and hexagon headed 25mm x 8mm bolts. Using a

10mm spanner, tighten the bolts and adjust for height as

necessary.

FITTING THE FLUE CONNECTOR.

If your Dovre is to be connected to the chimney via the rear flue

connector, proceed as follows.

Remove the fixed circular flue cover plate on the rear of the stove

using the kit supplied (part no 72301.0)

Apply a thin and even coat of fire cement to the flange on the flue

spigot. Fix the flue spigot in position using the 2 threaded hook

bolts, nuts and washers and tighten using a 13mm spanner.

If your Dovre is to be connected to the chimney via the top flue

connector, proceed as follows.

Remove the fixed circular flue cover plate on the top of the stove

using the kit supplied (part no 72301.0)

Apply a thin and even coat of fire cement to the flange on the flue

spigot. Fix the flue spigot in position using the 2 threaded hook

bolts, nuts and washers and tighten using a 13mm spanner.

REFIT THE REAR HEAT SHIELD (IF REAR FLUE CONNECTION IS

USED IT WILL BE NECESSARY TO KNOCK OUT THE CUT OUT

FLUE SECTION ON THE HEAT SHIELD.

Cast iron ash pit cover (part no 054020)

Place the ash pan in position. Attach conical shaped knob to the

threaded rod located on the right hand side of the stove under the

ash lip.

Refit the log guard.

INSTALLATION

HEARTH & CLEARANCE REQUIREMENTS

INSTALLATION AGAINST A WALL

For installation as a free standing unit e.g. against a

wall. (See fig.4)

The minimum hearth required is 840mm (33") x 840mm (33")

and the unit must not be placed less than 125mm (5") from the

back and sides of the hearth. The wall must be constructed from

non-combustible materials and must be a minimum height of

1200mm (48"). The required wall thickness will depend on the

distance between the back of the stove and the wall. If this

distance is less than 50mm (2"), the wall should be at least 200mm

(8") thick. If the distance from the back of the stove to the wall is

between 50mm (2") and 150mm (6"), the wall thickness must be

at least 75mm (3") thick. If single wall flue pipe is attached to the

appliance, the pipe should be a minimum of three times its

diameter from any combustible materials.

INSTALLATION IN A FIREPLACE RECESS

For installation in an fireplace recess or inglenook the hearth must

extend 500mm (20") in front of the recess and extend either side

of the recess by 150mm (6")

The distance the hearth must protrude in front of the appliance

should be a minimum of 300mm (9")

The minimum thickness of hearth should be 125mm (5") and this

may include the thickness of a concrete floor including hearth

tiles. If a hearth is constructed and / or supported on timber, the

timber should be at least 550 mm (10") away from the top surface

of the hearth.

If a timber mantel is installed, the distance from the stove body

and / or any single skin flue pipe, if attached to the top of the

stove, to the mantel must be a minimum of 450mm (18").

CHIMNEY CONNECTIONS

CONNECTION FROM THE TOP OF THE

APPLIANCE (See fig.5)

A non-combustible register plate should be fitted to the

lower section of the chimney.

125 mm (5") diameter 316-grade 1mm thick stainless steel flue

pipe or vitreous enamel pipe suitable for use with solid fuel

appliances should be used to connect the top spigot of the stove to

the chimney or chimney liner. All connecting joints must be

female pointing up and joints should be properly sealed with fire

cement. If the chimney is not immediately above the stove, off set

bends of either 30 degree or 15 degree angles may be used. Try to

avoid long runs of pipe that are not vertical.

CONNECTION FROM THE REAR OF THE

APPLIANCE (See fig.6)

A non-combustible register plate should be fitted to the

lower section of the chimney.

125 mm (5") diameter 316-grade 1mm thick stainless steel flue

pipe or vitreous enamel pipe suitable for use with solid fuel

appliances should be used to connect the rear spigot of the stove

to the chimney or chimney liner. All connecting joints must be

female pointing up and joints should be properly sealed with fire

cement. If the chimney is not immediately above the stove, off set

bends of either 30 degree or 15 degree angles may be used. Try to

avoid long runs of pipe that are not vertical. Start by connecting a

90-degree or 45 degree "T" section to the flue spigot at the rear of

the stove.

NEVER INSTALL HORIZONTAL PIPE RUNS OVER

ACCESS FOR SWEEPING CHIMNEY

The chimney should be checked and swept at least once a year and

it is important to allow provision for gaining access to the

chimney. On masonry chimneys, a standard soot door, obtainable

from your Dovre dealer, can be used. On other factory made

chimneys, it is important to ensure an access-cleaning door is

provided. It is advisable to ensure that the connecting flue pipe to

the chimney has an access door fitted. An access door close to the

appliance will also facilitate the use of a chimney vacuum cleaner

to ensure clean appliance maintenance.

AIR SUPPLY

Your Dovre 350 CB requires an air supply to the room. The air

vent should have a minimum air flow area of 220 sq. CMS (4" sq.)

CHIMNEY DRAUGHT

DRAUGHT REQUIREMENT:

Too much draught will cause excessive heat outputs and fuel

consumption. Inadequate draught may cause smoke emission to

the room and poor combustion resulting in a build up of tar and

creosote deposits on the glass, inside walls of the appliance and the

chimney.

FOR EXISTING CHIMNEYS, always ensure that the chimney is

checked and swept prior to the installation taking place.

This is one of the most important aspects of the installation of your

Dovre stove. It is important to ensure the following.

MASONRY CHIMNEYS

The chimney must be sound, in good condition and must not be

shared with another appliance. In the event of the chimney being

unlined, it is advisable to have a survey carried out to check for the

presence of leakage and other defects. Lining the chimney with a

suitable liner for wood burning and solid fuel burning

applications, will improve the performance and efficiency of the

stove.

THE ADVANTAGES OF A LINED CHIMNEY

With most unlined chimneys, the cross section of the chimney is

excessive as in the case of large old inglenook fireplaces. Because

of the large volume of cold air in large chimneys, it is difficult for

the flue gases to rise easily through the chimney. This causes the

unburned volatiles in the smoke to adhere to the chimney walls.

The inner surfaces of some unlined chimneys are rough with

jagged edges causing difficulties in obtaining a good draught.

Unlined chimneys are often defective with cracks leaking fumes

into other parts of the house.

Larger, unlined chimneys, being cold, encourage the formation of

tars (wood smoke condensation), which can penetrate the walls of

the chimney leaving unpleasant black stains on internal plastered

walls.

PREFABRICATED CHIMNEY SYSTEMS

If a masonry chimney is not available, there are a number of

INCORRECT

proprietary brand prefabricated flue systems available. Your Dovre

Dealer will be pleased to offer information and advise on this
