SECTION 4
MAINTENANCE
Servicing Notes
•
Servicing should be carried out annually by a competent person such as a CORGI
registered engineer. This is a condition of the Flavel 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 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.
•
We recommend that during the annual service, replacement of the pilot is carried out.
The pilot must be changed as a condition of the extended guarantee.
