In the event where a stove is fitted to a central heat-
ing system which is undersized in relation to the
nominal heat output to boiler then the stove will
operate satisfactorily but will be unable to achieve
the nominal heat output to room as the thermostat-
ic damper will shut off the air supply to prevent an
overheat situation in the boiler.

NOTE:-
The controls may become hot when the stove is in
operation, use tools or glove provided to adjust the
controller when the stove is hot.
A boiler model stove will provide heat into the boiler
and also to the room in which it is situated. The heat
to room is in a fixed relationship with the heat to the
boiler.
The heat to the boiler is controlled by the air supply
to the stove which is required to have a thermosta-
tic damper for safety reasons. When the tempera-
ture of the water in the boiler exceeds 55 ˚C the ther-
mostatic damper will begin to shut off the air supply,
should the water temperature continue to rise the
thermostatic damper will continue to close and if the
water temperature reaches 85˚C the thermostatic
damper closes the primary air supply fully.
For example:-
Where a stove provides 2kW to the
room and 8kW to the boiler and if the thermostatic
damper shuts down the air supply to provide 4kW to
the boiler, then the heat to room will decrease pro-
portionally to 1kW.
RECOMMENDED FUELS
All fuels should be stored under cover and kept
as dry as possible prior to use.
This appliance has been tested using seasoned
wood logs and manufactured briquetted smokeless
fuel (Ancit) for closed appliances, sized between
20g and 140g. Other fuels are commercially avail-
able and may give similar results. Wood logs up to
380mm long are suitable. All fuels should be stored
under cover and kept as dry as possible prior to use.
Do not use fuels with a Petro-coke ingredient as this
may cause the grate to overheat, causing damage.
Reduced outputs will result when fuels of lower
calorific values are used. Never use gasoline or
gasoline type lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or freshen up a fire in
this heater. Keep all such liquid well away from the
heater at all times. Operate the stove only with the
fuelling door closed except for re-fuelling.
This stove has obtained HETAS Ltd approval for
burning natural and manufactured smokeless fuels
only as detailed in recommended fuels below.
HETAS Approval does not cover the use of other
fuels either alone or mixed with the recommended
fuels listed, nor does it cover instructions for the use
of other fuels.
