COAL LAYOUT
The base and front coals should be
positioned as shown. The base locates
onto the rear shelf and sits central and
pushed back. The front coal moulding
is positioned centrally in its channel
with the cut out on the right as
shown.
Note the pilot position on the right
hand side of the burner.
It is important for clean burning that
the correct coal is fitted in the correct
place.
There must be a clear gap between the two sets of coals.
Always replace the glass after laying the coals.
Do not attempt to use the unit with broken / damaged glass or coals.
Do not use additional or non standard coals.
Note
: Model 4247 is supplied with pebbles instead of coals and the brick effect has been reversed during the manufacturing process.

TEST THE GAS PRESSURE
. Turn the fire on full, attach a manometer to the inlet test point
and ensure there is a pressure of 20mb (+/- 1mb) for natural gas appliances or 37mb for
propane appliances. Now turn on every other gas appliance in the house and re-check
the pressure. The pressure must still be within the tolerance of +/- 1mb. Now turn off all
the other gas appliances and turn the fire down to pilot only, the pressure must still be
within the tolerance of +/- 1mb. If it is not TRANSCO, BORD GAIS or the propane supplier
must be called to adjust the governor to the house before the fire can be commissioned
further.
Call outs to fires with incorrect pressures will be chargeable.

TESTING points to note...
Before testing ensure that the room size is correct for the heat output of the fire. 30m³
for 2.5kw output, 40m³ for 3.5kw and 50m³ for 4.2kw.
In all installations regardless of room size there must be an air vent positioned at least
one meter from the fire at either high or low level through an outside wall providing
100cm² of free air. (For the Republic of Ireland 2 vents of not less than 60cm² each must
be provided at high and low level, with minimum vertical separation of 1.6m).
The analyser used must be manufactured to BS7967 and the test must be carried out in
accordance with BS5871 Pt 4
