5.1 Lighting and Testing
Make sure that the electrical supply to the back boiler is
isolated.
The fire front is fitted with a combustion products
discharge safety device which will shut it down if there
is a lack of oxygen. If the fire shuts down frequently for
no apparent reason the first things to be checked are the
chimney and air inlets into the room. An additional
cause could be that the filter in the gas tap is blocked.
Any problems found must be put right, by a competent
person before the fire is used again.
The combustion products discharge safety device MUST
NOT be adjusted or disconnected. If replacing use only
the correct and approved parts.
Remove the pressure test nipple screw and fit a suitable
pressure gauge, see diagram 5.1.
Place the right hand side panel onto the pins, see
diagram 4.10, but do not secure at this time.
Turn the gas service cock to back boiler and fire ON,
see diagram 3.4.
To check for gas soundness use the pressure drop
method and apply suitable leak detection fluid to all
joints, replace glass panel, see diagram 3.2.
Fit the control knob to the tap spindle, see diagram 5.2.
IMPORTANT. If the burner does not light within three
seconds, release the tap, wait ten seconds and repeat the
lighting operation.
Push the control knob fully in and turn it anti-clockwise
to 1 - ignition, see diagram 5.2, clicking of the ignition
will be heard and the burner will light.
Keep the knob pushed in for ten seconds, to energise the
flame supervision device, during this time the ignition
system will continue to operate, indicated by the
clicking.
Air may be present in the supply to the fire front so that
the initial lighting operation may need to be repeated.
With the burner lit, visually check for leaks whilst
changing tap settings.
To change settings:
0 - 1 Push in and turn
1 - 2 Push in and turn
2 - 3 Push in and turn
3 - 4 Push in and turn
If the burner goes out, wait three minutes before
relighting, for any other reason wait for two minutes.
Check that the gas pressure is as stated in the Data
Section 1.3 or on the Data Label. (Right hand side panel)
If there is any doubt about the gas rate, check at the
meter, having first turned off all other gas appliances and
pilots.
