250 with Smoke Control Installation & User Instructions
8
6.7 Wood burns best on a bed of ash (approx 1” deep).
A bright and clean firebox indicates the appliance is
burning well.
6.8 Do not load fuel above the log guard and the lower edge
of baffle at the back of the firebox, see Diagram 7.
Fuel Overloading
The maximum amount of fuel specified in this manual
should not be exceeded, overloading can cause excess
smoke.
6.9 Do not burn continuously with the door open.
7. Running the Appliance
Multi-fuel
7.1 Allow the fire to become established before adding the solid
fuel:
—Set air controls, see Diagram 10.
Primary Air Control
50%
10
Airwash Control
50% Open
7.2 De-ash the grate before re-fuelling (see User Instructions,
Section 7).
Open the Primary Air Control fully to establish a glowing
bed before adding new fuel.
Burn new fuel at a high temperature for a few minutes before
adjusting the Primary Air Control to the desired setting.
Refuel little and often for clean, efficient burning.
When burning solid fuel more primary air will increase the
heat output and burn the fuel more quickly.
A small amount of Airwash can sometimes help to keep the
glass clean but will reduce efficiency.
7.3 Experience establishes settings to suit personal preference.
7.4 Do not burn large amounts of fuel with the Primary Air
Control on a low combustion setting for long periods of
time. This reduces the glass cleaning effect of the Airwash
and causes tars and creosotes to build-up in the appliance
and flue system.
User Instructions
7.5 When in use, burning the appliance at a high temperature
for a short period reduces tars and creosotes.
WARNING: DO NOT OPERATE THE APPLIANCE WITH
THE PRIMARY AIR CONTROL OPEN FOR LONG
PERIODS OF TIME AS THIS COULD CAUSE OVER-
FIRING AND MAY CAUSE PERMANENT DAMAGE.
7.6 ONLY USE APPROVED SMOKELESS FUELS IN A
SMOKE CONTROL AREA.
7.7 Only anthracite or smokeless fuels suitable for use in
closed appliances must be burned in this appliance.
7.8 Donotburnbituminouscoal,‘petro-coke’orother
petroleum based fuels as this invalidates the product
guarantee.
7.9 Do not load fuel above the log guard and the lower edge
of baffle at the back of the firebox, see Diagram 7.
8. Burning Tips
8.1 Fuel Quality (Wood)
Use wood with a moisture content of less than 20%.
Seasoned logs have the bark beginning to lift and peel away
and cracks radiating from the centre. They feel lighter than
fresh cut wood of a similar size and sound hollow when
struck against each other. Logs should not feel damp or
have moss and fungal growths.
Symptoms related to wet wood:
— Difficulty starting and keeping a fire burning well.
— Smoke and small flames.
— Dirty glass and/or firebricks.
— Rapid creosote build-up in the chimney.
— Low heat output.
— Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
Run at a high temperature for a short period each day
to avoid large build-ups of tars and creosote within
the appliance and the flue system. Use Stovax Protector
chimney cleaner to reduce this problem.
9. Shut Down
9.1 If there is still burning fuel in the firebox, Dovre do not
recommend shutting down the air controls completely
unless there is a chimney fire in progress (see Section 9
for advice). Closing the controls during the burning process
will cause poor combustion and could lead to a build up of
gasses that could ignite dangerously.
9.2 Always have enough air entering the stove to maintain some
flame within the firebox.
9.3 If it is necessary to shut down the appliance then run on a
high setting until all of the fuel has been burnt before closing
the air controls.
