5.8 De-ash the firebed 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 (see Diagram 7) for a
few minutes before adjusting the Primary Air Control to
the desired setting.
Refuel little and often for clean, efficient burning.
5.9 Experience establishes settings to suit personal preference.
5.10 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.
5.11 When in use, burning the appliance at a high temperature
for a short period reduces tars and creosotes.
5.12 Only anthracite or smokeless fuels suitable for use in
closed appliances must be burned in this appliance .
5.13 Do not burn bituminous coal, ‘petro-coke’ or other
petroleum based fuels as this invalidates the product
guarantee .
5.14 Do not load fuel above the log guard and the base of
the baffle at the back of the firebox (see Diagram 5).
REFUELLING
5.15 De-ash the fire bed before refuelling, see Ash Removal
—
Open the Primary air control fully to establish a
glowing bed before adding new fuel.
—
Do not refuel when a large amount of flame is
present in the firebox as this could cause smoke or
flames to spill into the room.
—
Close the doors immediately after refuelling.
—
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.
5.16 Do not re-fuel the stove above the level of the log guard
or the base of the baffle.
THERMOSTAT OPERATION
5.17 This appliance can be fitted with a thermostat kit to
control the temperature of the boiler. See the instructions
included in the kit for operation details.
USER INSTRUCTIONS
6. BURNING TIPS
6.1 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.
—Rapid creosote build-up in the chimney.
—Low heat output.
—Short burn times, excessive fuel consumption and
blue/grey smoke from the chimney.
Burn 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.
6.2 Fuel Quality (Solid Fuel)
Use recommended solid fuels approved for use with closed
appliances.
Symptoms related to unsuitable fuels include:
—Difficulty starting and keeping a fire burning well.
—Smoke and small flames.
—Dirty glass and/or fire bricks.
—Short life span for Grate and Baffle.
—Permanent staining of glass.
6.3 Air inlets puffing smoke
Combustion gases can build up in the firebox and ignite
as small explosions, causing smoke to puff out of the air
inlets and other openings. This occurs if the air controls
are shut soon after adding new fuel to a very hot fire. Stop
by opening the air controls to increase combustion air and
burning rate.
6.4 Flue Draught
The chimney has two main functions:
1) To safely remove the smoke, gases and fumes from the
house.
2) To provide a sufficient amount of draught (suction) in the
appliance ensuring the fire keeps burning.
