SERVICING
Gas catering equipment should be routinely serviced to ensure a long trouble-free life. With this in
mind it is recommended that the appliances are serviced every 6 months by a competent gas engineer.
Please see page 17 “Service” for information on authorised service agents.
(J5 & J10 General service).
1.
Carry out a general check of the installation paying particular attention to the following:-
has the unit been installed using the correct hose?
does the unit have a safety chain?
does the equipment have a separate isolation valve?
2.
Check all components for correct operation and replace where necessary, following the
appropriate instructions.
3.
Visually check the burner operation, closely observing the flame picture and look for evidence of
any debris or damage. Remove burner and clean or replace as necessary.
4.
Visually check the injectors and replace or clean as necessary (Clean using a brush with nylon
bristles or similar). Avoid using metal reamers or wire as this may damage or increase the orifice

nipple located on the burner.
