3. Replacing the Gas Valve
Refer to figure 8.
1. Loosen the screw attaching the ignition bar to the top of the gas valve.
2. Lift the ignition bar clear of the gas valve spindle.
3. Supporting the elbow with a wrench, unscrew the nut to the inlet elbow on the gas

nut connecting the thermocouple to the
interrupter block at the base of the gas
valve.

Important Note:
When connecting the ignition bar to
the top of the gas valve it is important
that the arm of the microswitch is
behind the ignition arm (See figure 9).
Ensure that when the ignition bar is
depressed the microswitch arm does
not pass over the top of the ignition
arm. If it does, or appears likely to
during future use, then the angle of the
ignition arm must be adjusted. Only
make the adjustment if absolutely
necessary. Do not overbend the
ignition arm.
Figure 9. Microswitch arm location
The screw at the base of the ignition
bar must be against the ‘D’ flat on the gas valve spindle.
4. Replacing the electronic spark generator battery
Refer to figure 10.
1.
Remove the battery from the electronic spark generator. To do this simply grip the
battery at the left hand side, lift and pull to the left.
Remove the old battery from the work area.
Obtain a new battery
and fit this into the

electronic spark
generator. To do this
hold the battery so
that the positive

5. Relief Panel operation
The relief panels on the underside of the firebox should be held in place by their spring
retainers, but should be capable of opening when the pressure within the firebox becomes
too great.
• To check the operation of the
relief panels push them down
from inside the firebox. They
can be accessed behind the
lower ceramic support by first
removing the two cross logs
and front log. (See figure 11).
Push down by 40-50mm and
ensure that they open easily
and freely. There should be
no restriction.
• If there is any restriction or
metallic scrapping sound then
the relief panels may be
coming into contact with the
stop plates. These are located
on the underside of the
firebox behind the relief
panels and are to ensure that
the springs are not over bent
during operation. If the relief
plate is coming into contact
with the stop plate then push
Figure 11. Relief panels
the bottom of the stop plate
towards the rear of the appliance by about 1/8th inch. Try the operation of the relief
plate and ensure that it closes against the base of the firebox. It is Important that
the relief doors operate easily and freely before leaving the
appliance.

6. Adjusting the height of the ignition bar
When refitting the Fascia it is important that the height of the ignition bar is
adjusted to ensure smooth operation.
The height of the ignition bar can be adjusted to suit the slot in the fire front. The
adjustment must be made before the window is refitted as follows:
1.
Locate slots in the fascia over the claws at the sides of the main appliance (figure.
12).
Figure 12. Fascia locating
2.
Angle the fascia up and turn the ignition bar to test if it will project through the slot
in the fascia.

If the ignition bar does not
locate satisfactorily
through the fascia, loosen
the screw securing the
ignition bar sleeve (figure.

Adjust the height of the
ignition bar so that it can
rotate freely through the
slot. Retighten the sleeve
screw.
The thermostat wheel
height can be adjusted by
simply sliding it up or
down the spindle and the
tightening the bushing
below so that it is flush
against the wheel (figure

• Without replacing the glass window, fit the fascia. Check for smooth operation of the
ignitor lever. If the ignitor lever contacts the fascia at its lowest depressed position,
adjustment is required. Insert a screwdriver between the firebox and fascia (through
the void space where the glass window would be) and loosen the set screw halfway up
on the ignitor bar. Adjust the ignitor lever up to almost the top of the opening in the
fascia and tighten set screw. Re-check operation of ignitor lever to ensure no contact
with fascia in the upper released or lower depressed position. Remove fascia again.
• With the glass window still removed, re-connect the gas supply to the heater and carry
out a leak test on all of the gas connections up to the control valve. Next light the
fireplace and leak test between the control valve and the burners. Shut off the
fireplace.
• Replace the glass window as in the Installation and Owner’s manual. Ensure window
is completely down in lower support track and all three upper buckles secured.
• Fit the Fascia and ignition bar knob.
• Conduct full operational checks as in the Installation and Owner’s manual.
