INSTALLATION
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 regulator 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.
4) Light the pilot and turn the valve to "ON"
position. Read manometer.
5) The pressure check should be carried out
with the unit burning and the setting should
be within the limits specified on the safety
label.
6) When finished reading manometer, turn off
the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8"
flat screwdriver. Note: Screw should be
snug, but do not over tighten

Gas Inlet
GAS CONNECTION
The gas connection is a 3/8" NPT 90 o elbow. The
gas line can be rigid pipe or to make installation
easier, use a listed flexible connector and/or
copper tubing if allowed by local codes. Since
some municipalities have additional local codes
it is always best to consult with your local
authorities and the CAN/CGA B149 installation
codes.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
The gas control valve is under the unit, behind
the drop down door and control panel. The gas
inlet is located on the left side of the unit (viewed
from the front). The inlet fitting is a 3/8" male
flare.
When using copper or flex connectors use only
approved fittings. Always provide a union so
that gas lines can be easily disconnected for
burner and/or valve 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 solu-
tion or gas leak detector. Do not use
open flame for leak testing.
Note: Prior to any pressure testing
of the gas supply piping system that
exceeds test pressures of 1/2 psig,
this appliance must be disconnect-
ed from the piping system. If test
pressures equal to or less than 1/2
psig are used then this appliance
must be isolated from the piping
system by closing its individual man-
ual shut-off valve during the testing.
