Check the gas pressure
(Figs 7 and 11)
(a)
Remove the packing securing the coal bed as follows:
(i)
Slide the glass front panel retaining clamps
sideways.
(ii)
Lift the glass front panel bottom edge out of the
locating channel and carefully remove the glass
front panel.
(iii)
Remove the packing securing the coal bed.
(iv) Carefully remove the coal bed and withdraw it
from the plastic bag.
(v)
Replace the coal bed and glass front panel.
(b)
Remove the pressure test point sealing screw from the
control tap and connect a pressure gauge.
(c)
To light the fire burner:
Push in and turn the fire
control knob anti-clockwise to the positive stop. The
pilot which can be seen through the lower right hand
gap between the coal should now light. If it fails to light
turn the control knob to the ‘OFF’ position and repeat
until lighting occurs. Continue to hold in the control
knob for a further 15 seconds. Release slowly and the
pilot should stay alight.
CAUTION: If the pilot does not light or stay alight or if
the pilot flame goes out for any reason turn the control
knob to the ‘OFF’ position and wait for 3 minutes before
attempting to light the pilot again.
(d)
Push in the control knob and turn fully anti-clockwise.
Check that the ignition is satisfactory.
(e)
Check the fire pressure with the control knob turned
fully anti-clockwise. The pressure should be 12.5mbar ±
1.0mbar (5.0 in wg ± 0.4 in wg). No adjustment is
provided on the fire. Turn the control knob to the ‘OFF’
(
) position. Remove the pressure gauge and refit the
pressure test point sealing screw. Turn the fire on full
again and check for gas soundness using a suitable
leak detection fluid.
TEST FOR SPILLAGE
(a)
Check that all four edges of the closure plate are
sealed.
(b)
After fitting the fire ensure that all doors and windows of
the room are closed and they are not opened until the
fire has been checked for clearance of products.
(c)
Light the fire and leave on full rate for 5 minutes.
(d)
The fire should be checked visually for the absence of
spillage by holding a smoke match 50mm (2in) inside
the draught diverter behind the fire ensuring that the
smoke is drawn into the flue outlet (Fig.8). If there is
any doubt repeat the test after a further 10 minutes. If
spillage still persists the chimney may be faulty. The
cause of the fault MUST be identified and corrected
before leaving the fire installed. IF THE FAULT
CANNOT BE CORRECTED, TURN OFF AND
DISCONNECT THE GAS SUPPLY TO THE FIRE -
SEEK EXPERT ADVICE.
(e)
IMPORTANT NOTE:
If there is a fan in the room or
adjoining room then the spillage test must be repeated
with the fan turned on and any interconnecting doors
between the fan and the appliance left open.
(f)
Remove the control knob.
