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 10mm inside and
below the centre of the lower front edge of the top of the fire as shown
overpage in figure 25. (It is recommended that a suitable smoke match
holder is used when checking for clearance of combustion products).
The majority of smoke generated should be drawn back into the flue. If
spillage occurs or if in doubt, repeat the test after a further 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. See figure 24 below for details
of how to remove and re-fit the restrictor baffle.
d)
If spillage persists with the restrictor baffle removed, 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.
