does not have much effect before being burnt off. Steel and cast iron liners are resilient firebox materials and
will give reliable service without major cleaning or work on the firebox.
Baffle:
It is essential to check the top of the baffle for build-up of soot and ash regularly when in use and after a
long period of no use. From time to time remove the baffle if necessary to ensure that the flue way entrance
is clear. Take note of the baffle orientation when removing and ensure it is refitted the same way.
Thermostat:
It is very important to occasionally clean around the thermostat to ensure proper operation of the damper as
this regulates the amount of primary air and hence the burn rate of the stove. Firstly, remove the thermostat
knob by pulling it gently away from the thermostat and then remove the Left Side Casing by undoing the
two fixing screws. Then clean any ash that has built up around the damper of the thermostat and open and
close the thermostat to ensure that it is working properly. In the closed position it should seal tightly against
the body of the stove (see diagrams below)
Ashpan area
There are cleaning slots present in this area to ensure that any ash or debris that builds up between the ash
box compartment and the outer jacket of the boiler can be removed and hovered up. Use a screwdriver to
loosen and tease out the ash and debris and it can then be hovered away as shown below. Repeat on opposite
side.
