CHECKING FOR CLEARANCE OF COMBUSTION PRODUCTS
a)
Close all doors and windows in the room.
b)
Light the fire and allow to run for approximately 5 minutes on high
position.
c)
After approximately 5 minutes hold a smoke match just inside and
below the centre of the lower front edge of the top of the fire as shown
in figure 32 below (It is recommended that a suitable smoke match
holder is used when checking for clearance of combustion products).
All smoke generated should be drawn back into the flue. If slight
spillage occurs or if in doubt, repeat the test after a further 5-10
minutes.
d)
If spillage persists, the flue is not functioning correctly and a fault exists.
If, after investigation the fault cannot be traced and rectified, the fire
must be disconnected from the gas supply and expert advice obtained.
e)
If there is an extractor fan fitted any where in the vicinity of the
appliance, the spillage test should be repeated with the fan running on
maximum and all interconnecting doors open.
f)
After ensuring that the fire is safe to use it should be left on high
position to fully warm up. During this time a slight odour may be
noticed, this is due to the “newness” of the fire and will soon disappear.
