CHECKING FOR CLEARANCE OF COMBUSTION PRODUCTS (ALL
MODELS)
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 Fig. 21 overpage. (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.
If the test indicates that spillage is occurring and the flue
restrictor baffle has been fitted, it should be removed and the test
repeated after the fire has cooled, also see note at base of page.
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.
At this stage any minor adjustments to the coals should be made using
suitable long handled tongs and taking care not to damage the coals.
Finally, hand the Installation and Maintenance Instructions and the
Users Instructions over to the customer and explain the operation of the
fire.

In the event of spillage occuring after the restrictor baffle has been
removed, please ensure that the cast has been correctly sealed as shown
on page 10 and that the seal on between the firebox and the cast is
consistent. This can be checked by running a smoke match around the
perimeter of the firebox, smoke being drawn in indicates leakage between
the cast and the firebox. This must be rectified to ensure the seal is
consistent between the firebox and cast.
