3. APPLIANCE DATA
This product uses fuel effect pieces containing Refractory Ceramic Fibres (RCF), which are man-made
vitreous silicate fibres. Excessive exposure to these materials may cause irritation to eyes, skin and
respiratory tract. Consequently, it is important to take care when handling these articles to ensure that
the release of dust is kept to a minimum. To ensure that the release of fibres from these RCF articles
is kept to a minimum, during installation and servicing we recommend that you use a HEPA filtered
vacuum to remove any dust and soot accumulated in and around the fire before and after working on
the fire. When replacing these articles we recommend that the replaced items are not broken up, but
are sealed within a heavy duty polythene bag, clearly labelled as RCF waste. This is not classified as
"hazardous waste" and may be disposed of at a tipping site licensed for the disposal of industrial
waste. Protective clothing is not required when handling these articles, but we recommend you follow
the normal hygiene rules of not smoking, eating or drinking in the work area and always wash your
hands
before
eating
or
drinking
.

INSTALLATION
6.1 ireplace size.
The fireplace must comply with the requirements described in section .
6.2 ireplace flue pull.
Visually
inspect the flue for any obstruction, and that a smooth transition from the fireplace opening into the
flue is available. Close all doors and windows in the room in which the appliance is to be installed. After
confirming with a match that smoke is drawn into the flue, light a 13 gram smoke pellet and check that there is
a definite flow through the flue. Verify outside that the smoke exits from one terminal only and that the
termination is suitable. Observe, where possible, upstairs rooms and loft spaces for signs of escaping smoke
indicating a defective flue. If there is not a definite flow warm the flue for a few minutes and repeat the smoke
pellet test. If there is still no definite flow the flue may need remedial work – Do not fit the appliance until
there is a definite flow through the flue.

Preliminary
burner
checks
.
ome burner operations can be checked at this stage. Checking now will mean that less disassembly will be
required if any problems are found. A full check should still be made, however, after final installation.
Page 14
7.1.1 Lighting the fire
If closed, open the isolating inlet 'T' connector. Depress the control knob and rotate it anticlockwise to the pilot
ignition position. A 'click' will be heard as the integral piezo operates. A spark should be seen between the
electrode and pilot tip. Turn the control knob clockwise to the 'Off' position. Repeat this operation until a flame
appears at the pilot. There may be a delay before the pilot lights due to air being purged from the system.
When a flame appears at the pilot keep the control knob depressed and hold the pilot ignition position for five
seconds. When the control knob is released the pilot flame should remain lit.
7.1.2 Operating the burner.
When the pilot burner is operating properly, gradually turn the control knob anticlockwise to 'HIGH' (Depress
the knob slightly to get past the pilot ignition position). The main burner should now light. Depress the control
knob slightly to release from the 'HIGH' position and turn back (clockwise) to 'LOW'. While turning, the burner
flames should gradually become lower but remain alight. Depress the control knob slightly to release from the
'LOW' position and turn back (clockwise) to the Pilot ignition position. The main burner should extinguish but
the pilot should remain alight. Depress the control knob slightly and turn back (clockwise) to turn OFF.
This will extinguish the pilot.
7.1.3 Checking the inlet pressure.
The appliance is pre-set to give the correct heat input at the inlet pressure shown in section 3 of this manual.
No adjustment is necessary.
1. Check the inlet pressure by fitting a pressure gauge at the test point. The test point is on the inlet 'T'
connector ( ee figure 7). Check the pressure with the appliance alight and set at maximum output.
