2. To carry out the test you will need a 500mm emplume
tube and a torch.
TEST: WHERE NO FAN IS PRESENT
Close all outside doors and doors and windows in the room in
which the appliance is installed.
Light the fire front only. After 5 minutes apply spillage test.
Position the smoke match tip under the fire front flue duct on the
draught diverter lip by inserting the emplume tube 370mm from
the outside edge of the louvres, see diagram 6.3. During test
smoke should be drawn into the draught diverter and between
the fire front flue duct and the draught diverter lip. If spillage
occurs leave fire front alight for up to a further 10 minutes and
repeat tests.
Next, light the boiler only and after 10 minutes apply spillage test
by positioning smoke match tip as described above, and shown
in diagram 6.3. If spillage occurs, leave the boiler alight for up
to a further 5 minutes and repeat test.
Now light the boiler and fire front. After 10 minutes apply
spillage tests by positioning smoke match tip as described
above, and shown in diagram 6.3. During tests smoke should
be drawn into the boiler draught diverter. If spillage occurs,
leave the boiler and fire front alight for up to a further 5 minutes
and repeat tests.
Note: If spillage does occur smoke will be visible exiting the top
of the fire casing.
TEST. WHERE A FAN IS PRESENT
(A fan means an extractor fan, or a fan for other open flued
appliances, or a circulating fan for a warm air unit, whether or not
gas fired). With the fan switched off carry out the appropriate
spillage test with all doors and windows closed, as above.
If the above tests are satisfactory continue as follows,
Open all doors connecting the room containing the appliance
and the room in which the fan is fitted. Close all other doors and
windows in the premises.
If the fan is in the same room as the appliance close all doors
and windows in that room. Switch on fan and repeat spillage
test as above.
In ALL cases, if spillage continues after the specified test
periods steps MUST be taken to put right the fault(s).
Possible causes include, flue obstructions, down draught or
restricted fresh air supply into the room.
