ACTION
Switch fan "off" immediately. Open windows
and doors etc., to disperse fumes. Remove
all burning fuel from boiler. Locate and
remove cause of blockage.
DO NOT ATTEMPT TO USE BOILER UNTIL
TROUBLE HAS BEEN RECTIFIED -
COMBUSTION FUMES ARE DANGEROUS.
Increase height of chimney above roof ridge
or adjacent building. If the foregoing is not
possible fit an anti-downdraught flue terminal
such as an 'OH' pot.
Although the Idling Screw is factory set to
suit most conditions, chimneys giving a high
draught may require a reduction in the Idling
Setting to limit the air input. Release lock-
nut and screw out Idling Screw one or two
turns, then tighten lock-nut.
Fit an additional draught stabiliser in the
chimney or flue-pipe.
Check operation of thermostat for ON-OFF
switching. Replace thermostat if switch
faulty. Ensure that thermostat phial is fully
inserted in its pocket.
Check seal and replace if necessary
Check seal and replace if necessary.
Screw in Idling Screw one or two turns to
increase air supply.
Declinker firebed until 'fresh' fuel is seen
and re-light.
Clean boiler flue-ways and sweep chimney.
Ensure that draught stabiliser closes when
draught is low..
Ensure fuel is reasonably dry before using.
When ordering from Fuel Supplier specify
for use with Trianco TRG boiler. (see page 1)
Empty hopper and remove obstruction. Use
a sieve to remove oversize fuel and foreign
matter.
Increase thermostat setting.
Check electrical supply for temporary cut.
Check fuses.
The boiler should have shut down to a safe
condition due to the operation of the Safety
Switch and the red warning light will be ON.
Open windows and doors to disperse any
fumes that may have been emitted during
the operation of the safety switch. Locate
and remove cause of blockage which might
be either in the flue pipe or chimney.
DO NOT ATTEMPT TO USE THE BOILER
UNTIL THE BLOCKAGE HAS BEEN
CLEARED. COMBUSTION FUMES ARE
DANGEROUS.
