GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig. (3.45
kPa). Disconnect piping from valve at pres-
sures over 1/2 psig.
The manifold pressure is controlled by a regu-
lator built into the gas control, and should be
checked at the pressure test point.
Note: To properly check gas pressure,
both inlet and manifold pressures
should be checked using the valve
pressure ports on the valve.
1) Make sure the valve is in the "OFF" position.
2) Loosen the "IN" and/or "OUT" pressure
tap(s), turning counterclockwise with a
1/8" wide flat screwdriver.
3) Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" ID hose.

GAS LINE
INSTALLATION
The gas line is brought through the right of the
appliance. The gas valve is situated on the right
hand side of the unit and the gas inlet is on the
right hand side of the valve.
The gas line connection may be made of rigid
pipe, copper pipe or an approved flex connec-
tor. (If you are using rigid pipe, ensure that the
valve can be removed for servicing.) Since
some municipalities have additional local codes
it is always best to consult with your local
authorities and the CAN/CGA B149 installation
code.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or flex connectors use
only approved fittings. Always provide a union
so that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and flex
connectors are usually considered to meet this
requirement.
Important: Always check for gas leaks
with a soap and water solution or gas
leak detector. Do not use open flame for
leak testing.

Note: Output capacity:
The efficiency rating of the appli-
ance is a product thermal efficien-
cy rating determined under con-
tinuous operating conditions and
was determined independently of
any installed system.
Vent height may or may not change
your efficiency ratings.
HIGH ELEVATION
This unit is approved in Canada for altitude 0 to
4500 ft. (CAN1 2.17-M91) with the orifice sup-
plied.
PILOT ADJUSTMENT
Periodically check the pilot flames. Cor-
rect flame pattern has three strong blue
flames: 1 flowing around the thermopile,
1 around the thermocouple and 1 flowing
across the burner (it does not have to be
touching the burner).
Note: If you have an incorrect flame pat-
tern, contact your FPI dealer for
further instructions.
Incorrect flame pattern will have small,
probably yellow flames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.
