ABOUT YOUR HEATER
GENERAL DESCRIPTION
Your Slimfire is a burning log effect, gas space heating appliance with natural draft combustion system, intended
for use with Natural Gas and Propane. The burning log effect is achieved using two main burners with strategically

This heater has an electronic ignition. The pilot is only on when the heater is in operation.
Burner, logs and granules are contained in a glass fronted, sealed burner box.
Combustion air is drawn from the room. Combustion product is exhausted via the flue discharge vent when
installed in a masonry chimney or when installed in a zero clearance box through a 100mmØ x 150mmØ twin
skinned flue to the outside of the house.
1. Fireplace / Masonry installation - Engine:
The appliance is directly mounted into an existing masonry fire place or a non-combustible/masonry enclosure
that has a chimney. When installed correctly the appliance is a flush to wall mount.
2. Zero Clearance installation:
The appliance is fitted within a sheet metal Zero Clearance Box Assembly that has been installed into a wall or
other suitable structure. Materials need not be non-combustible. When installed correctly the appliance is a
flush to wall mount.
