6. Appliance Installation Instructions
(To be carried out by a Registered GAS SAFE Engineer only – failure to comply with
this requirement will invalidate the Warranty)
6.1. General
GATHER:
This appliance is fitted with a gather unit which must be remaining attached
to the appliance. Removal of the gather will render the appliance dangerous. The
gather must be sealed with high temperature silicone fire cement.
FLUE:
The minimum flue requirement is 3 metres of 250mm diameter. Usage with any
smaller flue will render the appliance highly dangerous.
Clearances between the appliance and all combustible materials must conform to
national regulations.
The appliance must be installed and used in accordance with these instructions. Prior
to installation, ensure that the local distribution conditions (identification of the type
of gas and pressure and the adjustment of the appliance) are compatible.
The builders opening or fireplace opening must be constructed of a non-combustible
material.
Any flue damper plate or flue restrictor must be removed or fixed permanently in a
fully open position, or shall only be installed in accordance with national regulations.
The chimney must be swept before the appliance is installed. If the chimney is not
swept, there is a possibility that loose debris may fall onto the burner unit which may
result in damage and unnecessary service costs.
Before the appliance is installed a flue test in accordance with national regulations
should be carried out. The appliance must not be installed unless the chimney or flue
length is at least the length and size indicated in the section marked ‘Appliance
Technical Data’ earlier in this manual.
Under no circumstances should the appliance be installed and operated within any
premises without an adequate flue or chimney system.
A room ventilation air supply must be installed in accordance with national regulations
and should be checked regularly to ensure that it is free from obstruction.
Soundness of the input gas line should be checked prior to installing the appliance.
The gas connection must be made in accordance with national regulations.
An isolation valve (stop tap) must be installed adjacent to the appliance, which when
closed allows the complete burner and control assemblies to be disconnected for
maintenance and repair in accordance with national regulations.
Adjustment of the pilot assembly is not usually required, however during installation
the assembly may become misaligned. The gap between the pilot electrode and the
pilot should be 3.5 – 4.5mm allowing the spark to bridge the gap between the electrode
and the gas outlet on the pilot head, at the point where gas is ejected.
