THERMOSTAT AND DAMPER
PRESSURE CHECKS
The thermostat has been fitted and set correctly
during the manufacture. However it is advisable
to check the cold setting prior to lighting the fire
for the first time.
With the control knob turned fully clockwise (past
No.5) the circular damper plate should have a
gap of approximately 29mm between the
damper edge and the stove inner body face
when measured at the furthest point from the
control knob and in line with the actuation shaft.
Take care to measure this gap parallel to the
actuation arm centre line.
If this is not the case then please follow the steps
below to correct it.
To remove the thermostat:
 Pull the thermostat knob off the shaft.
 Remove the access cover plate using a
No.2 Pozi screw driver and then remove the
M5 screw.
Safety Vent Circuit
This circuit consists of a cold feed pipe, a
separate expansion pipe and expansion tank.
The possibility that water in the stove boiler may
boil can never be completely ruled out, and it
is therefore vital to ensure that cold water can
be provided to the boiler and steam vented
from it at all times.
The use of an expansion tank is important. This
should have a capacity of at least 7% of the
systems total water capacity. The cold water
feed pipe should be at least 22mm in diameter.
There must not be any shut-off valves in the
circuit. Pipes should be run so as to avoid air
locks. A safety valve should be fitted into the
expansion pipe close to the boiler. The
expansion pipe should not be branched off
from the cold water feed pipe to ensure that it
cannot be blocked by any sediment matter
originating from the expansion tank.
It is often possible and good practise to utilise
the primary flow and return as part of the safety
circuit. The ball valve and overflow pipe (28mm
diameter) from the expansion tank should be
copper. All pipes in unheated spaces should
be lagged.
Various examples can be seen on pages 10
and 11.
With solid fuel appliances, it is not practical to
provide a sufficiently rapid reaction for shutting
down the fuel in the event of a sudden rise in
water temperature. A temperature valve, or
preferably, a combined temperature and
pressure relief valve should be installed to
operate in the event of high water
temperature occurring.
