INSTALLATION INSTRUCTIONS
SITE REQUIREMENTS
1.1
The chimney or flue system must comply with the rules in
force.
1.2
Fireplace opening up to 450mm (18") wide by 600mm (24")
high will usually work with a 175mm (7") diameter flue.
Larger openings will require bigger flues. See diagram 1 as
a guide.
1. FLUE AND CHIMNEY REQUIREMENTS
1.3
The chimney or flue must be free from any obstruction.
Any damper plates should be removed or secured in the
fully open position, and no restrictor plates should be fitted.
1.4
The chimney should be swept prior to the installation of the
appliance - unless it can be seen to be clean and
unobstructed throughout its entire length.
1.5
Ensure that there is a smooth tapered transition from the
fireplace opening into the chimney or flue.
1.6
The flue pull should be checked prior to installation of the
appliance. Apply a smoke pellet to the flue or chimney
opening and ensure that the smoke is drawn into the
opening. If there is not a definite flow, pre-heat the
chimney for a few minutes and re-test the flow.
IF THERE IS STILL NO DEFINITE FLOW, THE CHIMNEY
MAY REQUIRE ATTENTION - SEEK EXPERT ADVICE.
2.1
Before installation, ensure that the local distribution
conditions (identification of the type of gas and pressure)
and the adjustment of the appliance are compatible.
2.2
Ensure that the gas supply is capable of delivering the
required amount of gas, and is in accordance with the rules
in force.
2.3
Soft copper tubing and soft soldered joints can be used, but
must not be closer than 50mm (2") to the base of the tray.
2.4
A means of isolating the gas supply to the appliance must
be provided independent of any appliance control.
2.5
All supply gas pipes must be purged of any debris that may
have entered prior to connection to the appliance.
It is important to ensure that any national ventilation
requirements are taken into account during the
installation of this appliance.
3.1
This appliance requires an air vent of at least 100cm
2
effective area.
3.2
It is essential to check for flue clearance, see installation
section 6, Commissioning. If spillage is detected, it may be
necessary to provide additional ventilation.
3.3
The ventilation is in addition to any openable window, and
although it must communicate with the outside air,
wherever possible, it can communicate with an adjacent
room provided that the space has a similar vent to the
outside.
