Pressure Setting
If the pressure is too high, the gas supply meter may be set incorrectly.
This should be checked with the fire running and if necessary reset
by the gas supplier. If the burner pressure is too low, then check the
inlet pressure with the appliance running. If this is less than the inlet
pressure stated in Table 1, it will need to be reset by the gas supplier.
If the setting pressure is too low, but the meter pressure is acceptable,
then a problem in the supply pipework is to be suspected. This may
be dirt and debris, kinked or inadequate size pipes, restriction in a
fitting, shut off elbow not fully open or solder flashing across a joint.
Identify the cause of the restriction and rectify. Switch the fireplace
off, disconnect the U gauge and refit the test nipple screw. Light the
fireplace and check test nipple for gas tightness. In the event that the
burner pressure is not in accordance with the figures stated in the Table
1 of these instructions, the appliance must not be commissioned, and
the dealer should be contacted for guidance.
The pressure regulator on manual models is preset and locked to avoid
tampering. If the pressure is not as specified in Table 1 on Page 3,
replace the burner assembly (see Page 16 for ordering information).
Replace the test point screws after pressure measurement ensuring no
gas leaks. All instructions must be left in the possession of the user for
safekeeping.

19.0 BRIEFING THE CUSTOMER
WARNING
Do not add logs or ornaments such as pine cones,
vermiculite or rock wool. Using these added items
can cause sooting.
All instructions must be left in the possession of the user for safekeeping.
If at all possible, show the customer how to light and control the appli-
ance and show the customer how to remove and replace the surround
assembly and glass door assembly.
After commissioning the appliance, the customer should be instructed
on the safe use of the appliance and the need for regular servicing.
Frequency of service depends on usage, but MUST be carried out
at least once annually. Advise that cleaning of the appliance may be
achieved when the fire is cold using a damp cloth and mild detergent
on most surfaces.
Advise that the fireplace will emit a "newness" smell for a time after
initial commissioning and that extra ventilation may be needed during
this time. Recommend that a guard be used for the protection of the
young, pets, the elderly and the infirm.
Advise the user to never place any objects on top of the appliance or
obstruction this area in any way.
A periodic visual check of the pilot flame and the burner flame should
be carried out.
The gap between the spark electrode and the pilot should be 1/8” to
3/16” to produce a good spark. There should be no need to adjust this
(DO NOT ATTEMPT TO ADJUST THE GAP). If under any circumstances
the piezo electric spark fails, the pilot cannot be lit manually.
Adjustment to the
pilot is Not allowed
