Commissioning the Fire
1. Remove the four radiants from their packing. Fit them
by inserting their upper edge into the heat exchanger
and then lowering them on to the burner rail. The lower
front edge should be flush against the radiant support rail.
2. Remove the pressure test point sealing screw and
connect a pressure gauge (Fig.5).
3. Turn on the gas service tap (at present supplying gas
to the boiler only) fully anti-clockwise. The service tap is
now supplying both the boiler and the fire (Fig.4).
4. Purge according to in GB BS 6891 and in IE the
current edition of I.S. 813 “Domestic Gas Installations”.
5. To light the fire - fit the fire control knob if not fitted and
ensure that it is fully clockwise. Push in and turn anti-
clockwise slowly to the positive stop to operate the igniter.
Repeat until the pilot and burner light. The burner flame
will be visible in the two centre radiants. Continue to hold
in the control knob for a further 15 seconds. Release
slowly and the pilot and burner should stay alight. If the
pilot and burner do not stay alight turn the control knob to
the OFF position fully clockwise and repeat.
6. Check that the fire burner crosslights smoothly by
pushing in the knob and turning fully anti-clockwise. Test
for gas soundness with leak detection fluid.
7. Check the fire pressure with the control knob in the
fully anti-clockwise position.The pressure should be
17.2mbar + 1.0mbar (6.9 in. wg. + 0.4 in. wg.).
8. Turn the control knob clockwise to the OFF position.
Remove the pressure gauge and refit the pressure test
point sealing screw, ensuring a gas tight seal.
9. Test for clearance of flue products as follows:
(a) Ensure that all doors and windows are closed.
IMPORTANT NOTE: If there is a ceiling or
extractor fan in the room or adjoining room
then the spillage test must be performed with
the fan turned on and any interconnecting
doors between the fan and the appliance
left open.
(b) Light the fire and turn to position 4.
(c) After running for 5 minutes take a lighted smoke
match and insert it into the smoke tube at the left
hand side of the fire leaving 3mm of the match
below the tube (Fig.6). No smoke emerging from
the side hole indicates clearance.
Smoke emerging from the side hole indicates
spillage and the test must be repeated after a
further 5 minutes.
If the fire does not clear its
products, further investigation must be carried out.
After a further 5 minutes with both the boiler and
the fire alight, insert a smoke match into the
boiler down draught diverter. Ensure that most of
the smoke is drawn into the flue (Fig.7).
If the boiler does not clear its products, further
investigation must be carried out.
10.Fit the case as follows:
(a) Remove the control knob. (PW5 Deluxe only)
(b) Lift the outercase over the heat exchanger and
locate the two 'vee' notches in the top of the case
into the 'vee' notches at the top of the inner case
(Fig.5).
(c) Secure the outercase to the inner case using the
two securing screws provided (Fig.5).
12.Hand the user the User’s Instructions, explain the
operation of the boiler and fire and leave the unit set to
suit their requirements.
13.Leave these instructions with the user or adjacent to
the gas meter.
