flue height of 12 feet is recommended. B-Vent
must be supported by a vent support - supplied
by vent manufacturer. See chart on this page
for minimum distances from roof.
TheFPI Insert incorporates its own internal
draft hood, so no additional external draft hood
is required.
Periodically check that the vent is unrestricted
and an adequate draft is present when the unit
is in operation. (See page 8 for spillage test.)
Before installing vent system ensure that the
damper plate is open and secure to prevent
the damper plate from falling down and crush-
ing the liner.
WARNING: Operation of this ap-
pliance when not connected to a
properly installed and maintained
venting system or tampering with
the blocked vent shutoff system
canresultincarbonmonoxide(CO)
poisoning and possible death.
Combustion and Ventilation Air
WARNING: This appliance needs
freshairforsafeoperationandmust
be installed with provisions for ad-
equate combustion and ventilation
air available to the room in which it
is to be operating.
Follow CAN/CGA B149 (in Canada) or ANSI
Z223.1 (in the USA) requirements, and any
local codes or regulations of the enforcing
authority.
Air for combustion is drawn in through the front
of the unit, therefore, the front of the unit must
be kept clear of any obstructions.
GAS PRESSURE TEST
The unit is preset to give the correct gas input
at the specified manifold pressures shown on
thelabel.The maximum gas manifold pressure
is:
Natural Gas 3.8" w.c.
Propane 11.0" w.c.

WARNING: Electrical Grounding Instructions
This appliance is equipped with a three pronged (grounding) plug for your protection against shock hazard and should
be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from
this plug.
This heater does not require a 120V A.C. sup-
ply for operation. In case of a power failure, the
burner switch and the optional remote control/
thermostat will continue to operate. However,
a 120V A.C. power supply is needed for the
fan/blower operation.
Caution: Ensure that the wires do
not touch any hot surfaces and are
away from sharp edges.
