GAS LINE

INSTALLATION

The gas line can be brought through either the
right or the left side 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.

Note: If the gas line is being installed from

the left side, be sure to leave room to
accommodate servicing of the fan.

The gas line connection may be made of rigid
pipe, copper pipe or an approved fl ex connector.
(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 fl ex connectors use only
approved fi ttings. Always provide a union so that
gas lines can be easily disconnected for burner
or fan servicing. Flare nuts for copper lines and
fl ex 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 fl ame for leak testing.

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
pressures over 1/2 psig (3.45 kPa).

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"
(3mm) wide fl at screwdriver.

Note: Output capacity. The effi ciency rating
of the appliance is a product thermal effi ciency
rating determined under continuous operating
conditions and was determined independently
of any installed system. Vent height may or may
not change your effi ciency ratings.

3) Attach manometer to "IN" and/or "OUT"

pressure tap(s) using a 5/16" (8mm) ID
hose.

4) Light the pilot and turn the valve to "ON"

position.

5) The pressure check should be carried out

with the unit burning and the setting should
be within the limits specifi ed on the safety
label.

6) When fi nished reading manometer, turn

off the gas valve, disconnect the hose
and tighten the screw (clockwise) with a
1/8"(3mm) fl at screwdriver. Note: Screw
should be snug, but do not over
tighten.
