SECTION 4
MAINTENANCE
Servicing Notes
Servicing should be carried out annually by a competent person such as a GAS
SAFE registered engineer.
This is a condition of the guarantee schemes.
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 oxypilot on the burner unit must also be changed as a condition of
the guarantee. The condition of the fuel-bed should be checked and
if necessary
the whole item should be replaced with a genuine replacement item.
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.
