This appliance is a high efficiency, unvented, flame effect gas heater.
It provides radiant and convected warmth both efficiently and safely

oxygen depletion sensor (ODS) which responds to the amount of
oxygen available in the room and shuts the heater off before the oxygen
level drops below 18%. 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.

tions must be handed to the user for safekeeping.
