18” Inset Taper 010710 
Relight the appliance and allow to run for five minutes with 
the gas control in the `HIGH’ position. Check for 
satisfactory clearance of combustion products by inserting 
a lighted smoke match into the opening 100mm below the 
top of the opening and 10mm in from the face of the 
surround (Fig. 21). 
The majority of smoke must be drawn up into the flue. If 
this does not occur, allow a further 10 minutes and repeat 
the test. Should spillage still occur, examine the chimney 
for fault and rectify. 
The test should be repeated if an extractor fan or fan 
powered flue appliance is fitted to the room. If there is a 
connected room with an extractor fan, the test should be 
repeated with all the connecting doors to that room 
opened.

2.8  ADVISING THE CUSTOMER 
Advise the customer on the following points: 
The lighting and extinguishing procedures that are described in section 1.3. 
They should read the `Instructions for Use’ section at the beginning of this booklet. 
The appliance should be serviced at regular intervals and checked for spillage in accordance with the method described in section 2.6. 
The curing effect of heating the coals will cause an initial odour. This is not harmful although additional ventilation (i.e. an opened window) 
may be required until the odour has disappeared. 
If the appliance is turned off or shuts off automatically, wait for at least three minutes before attempting to relight.

The front and fret illustrated (Fig. 22), is a recommended 
CROSSLEE front and fret. If an alternative front and fret 
is to be used on the appliance, it is very important to 
maintain the equivalent ventilation.
