return thermostat also ensures that
priority is given to the domestic hot
water. These thermostats are
available from ourselves if you are
unable to obtain them locally.
THERMOSTAT
Before lighting the fire check the
cold setting distance of the
thermostat.
With the control knob at the
minimum setting the flap should be 5
mm from the air inlet as shown in
Fig. 10.
To adjust the distance slacken the
locking nut and adjust as necessary.
When set correctly re-tighten the
locking nut. Ensure that the flap
opens and closes freely as the knob is
turned.
PRE LIGHTING
CHECK
Before initial lighting check the
following points:
1. The bottom grate bars must all be
fitted and should move freely and
easily when the riddling mechanism
is operated.
2. The plates round the sides and
back of the grate must be in position
and sitting correctly. The location of
the side fire plates, the back fire plate
and the ash shedding plates are
shown in Fig. 11.
3. The throat plate must be fitted in
the roof of the appliance - see Fig. 1.
4. Ensure that the overrun catch
swings freely and easily on its spindle
preventing the firedoors from closing
until the ashpit door has been shut.
