There is a small air bypass into the ashdoor and this
is normally sufficient when the thermostat is closed to
hold the fire at least 10 hours after banking. If the fire

OVERNIGHT BURNING
FIREDOOR SPIN VALVE
Heated secondary air enters the firebox through a
spin valve in the firedoor back plate while the valve is
open to assist combustion of smoke volatiles.
Close when burning anthracite. (See Fig.6)
The ashdoor spin valve allows additional air to the
firebox for marginal draught conditions. This can be
adjusted to suit your requirements. Close when set-
ting the cooker for overnight burning. (See Fig.7)
This plate is fitted by removing the hotplate and slid-
ing the insulating plate down between the boiler and
oven side. Make sure that the spacing projections are
facing the oven and the top flange is resting on the
boiler. Replace the hotplate.
The boiler insulating plate may be used with the sum-
mer plates or on its own as a means of reducing the
boiler output and increasing the heat to the oven.
