SECTION 4
MAINTENANCE
Servicing Notes
Servicing should be carried out annually by a competent person such as a
registered installer. The service should include visually checking the chimney and
fire opening for accumulations of debris and a smoke test to check for a positive
up-draught in the chimney. The pilot assembly must be changed as a condition of
the guarantee. The burner aeration port (situated on the rear face of the burner
adjacent to the injector on NG models only) must be checked for lint build up and
cleaned accordingly. The condition of the coals should be checked and
if
necessary the whole set should be replaced with a genuine replacement set.
The burner assembly is designed to be removed as a complete unit for ease of
access.
After any servicing work a gas tightness check must always be
carried out.
