Operation of controls: Check all
knobs etc are secure on their
spindles and that they work

fridge gas control is
turned to maximum the

quietly.The colour should
be mainly blue/green but

•
Grill burners: Flames may
develop yellow tips as
they heat up, especially
when using butane.

General comments: A
flame lifting away from the
burner indicates that the
pressure is too high.
A yellow flame causes
sooting and indicates the
pressure is too low. If
these faults occur, re-
check the regulator,
cylinders and pipes, adjust
as necessary.
•
Flues: Check security of fixings,
attachments to appliances and
flue terminals. Check for damage
and corrosion. Check for gas
leakage into the vehicle.

Check for satisfactory operation
by the following method: after
the appliance has been checked,
allow time for the
thermocouple to cool.Try to re-
light the appliance by turning it
on without pushing the gas
control knob in. If the appliance
does not light the FFD
is working.
•
Security: Check that all
appliances are securely fixed to
the vehicle/furniture and that no
‘play’ is present.Where
applicable check that the water
pipes are properly attached and
