.0 GENERAL INFORMATION

This appliance is a high efficiency, unvented, flame effect gas heater. It
provides radiant and convected warmth both efficiently and safely utilizing
the latest type catalytic convertor burner technology. The appliance does
not require a flue system of any type as the catalytic converter cleans
the flue products to provide a complete combustion system, which is
intrinsically safe.
These heaters are fitted with a specially designed pilot utilizing an oxygen
depletion sensor (ODS) which responds to the amount of oxygen avail-
able in the room and shuts the heater off before the oxygen level drops
below 18%. It must not be adjusted or put out of operation. If replaced
then manufacturers original parts must be used. The pilot can be relit
only when fresh air is available. Refer to the Combustion and Ventilation
Air section.
The appliance is designed to fit various types of situations as listed in
the installation requirements.
This appliance is factory set for operation on the gas type, and at the
pressure stated on the appliance rating plate.
Read all these instructions before commencing installation. All instructions
must be left in the possession of the user for safekeeping.
