d) there is an adequate air supply into the room,

e) an extractor fan is not fitted in the same room as the fire.

f) there is sufficient draw in the chimney. Once the chimney is warm
a draught reading of at least 2.5 mm (0.10 inches) water gauge
(25Pa) should be obtained.

Freezing

If a boiler is fitted do not light the fire if there is any possibility that
any parts of the system may be frozen.

Chimney fires

If the chimney is thoroughly and regularly swept, chimney fires
should not occur. However, if a chimney fire does occur then turn
the control knob to the minimum setting (see Fig. 1), and tightly
close the doors of the appliance. This should cause the chimney fire
to go out in which case the control should be kept at the minimum
setting until the fire in the appliance has gone out. The chimney and
flueways should then be cleaned. If the chimney fire does not go out

d) Do not attempt to relight fire until cause of fume has been

identified and corrected, if necessary seek professional advise.

The most common cause of fume emission is flueway or chimney

Fume Emission

Warning Note: Properly installed, operated and maintained this

appliance will not emit fumes into the room. Occasional fumes

from de-ashing and re-fueling may occur. Persistent fume emission

is potentially dangerous and must not be tolerated. If fume

emission does persist then take the following immediate actions

should be taken:

b) Let the fire out and safely dispose of the fuel from the

appliance.

a) Open doors and windows to ventilate the room and then leave

the premises.
