Wet Stove Installation Guide
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 practice 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 page 21.
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.

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.
