Vent Requirements
 The gas appliance and vent system must be vented directly to the outside of the building, and never
be attached to a chimney serving a separate solid fuel or gas-burning appliance. Each direct vent
gas appliance must use its own separate vent system.
 In addition to the requirements listed here, follow the requirements provided with the vent.
 A firestop is required whenever the vent penetrates a wall, floor, or ceiling (passes through framing
members). Use the included firestop. It incorporates a 3" clearance above, 1" clearance below and
to the sides of the vent.
Vent Clearances
 The vent must maintain the required clearance to combustible materials to prevent a fire. Do not fill
air spaces with insulation.

Altitude Considerations
 This heater has been tested at altitudes ranging from sea level to 6,000 feet. In this testing we have
found that the heater, with its standard orifice, burns correctly with just an air shutter adjustment.
 Failure to adjust the air shutter properly may lead to improper combustion which can create a safety
hazard. Consult your dealer or installer if you suspect an improperly adjusted air shutter.
Use a firestop when
passing through any
wall (WARNING: some
firestops provide a 1"
clearance above the
vent -- 3" is required for
this heater).
