INSTALLATION
GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas supply
piping system by closing its individual approved
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). Discon-
nect piping from valve at pressures 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 fl at 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.
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" fl at screwdriver.
Note: Screw should be snug, but do not over
tighten.
AERATION ADJUSTMENT
The burner aeration is factory set but may need
adjusting due to either the local gas supply or
altitude. Open the air shutter for a blue fl ame or
close for a more yellow fl ame.
Minimum Air Shutter Opening:
Fully Closed NG
1/2" LPG / ULPG
Note: Any damage due to carboning resulting
from improperly setting the aeration
controls is NOT covered under warranty.
HIGH ELEVATION
This unit is approved for altitude 0 to 4500 ft. (CAN/
CGA 2.17-M91) or AS/NZS 5601.1
GAS LINE
INSTALLATION
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 servicing.
Flare nuts for copper lines and fl ex connectors are
usually considered to meet this requirement.
NOTE: A shutoff / dante valve should be sup-
plied in or near the unit (or as per local codes)
for ease of servicing this appliance.
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.
