GAS PIPE PRESSURE
TESTING
The appliance must be isolated from the gas sup-
ply 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.
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.
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.
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 flame or
close for a more yellow flame.
Minimum Air Shutter Opening:
Fully Closed
NG
1/4"
LP
See LP conversion instructions (Steps 1-3 & 8) in
this manual for aeration adjustment instructions.
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).
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 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.
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 flame for leak testing.

dealer for further
instructions.
Incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact
with the rear burner or flame sensor.

pattern has two strong blue flames: 1 flowing
around the flame sensor and 1 flowing across
the burner (it does not have to be touching the
burner).

NOTE:
The two PTO50s have a combined minimum
input of 84,000 Btu - NG/ 98,000 Btu - LP and
max. input of 128,000 Btu - NG / 124,000 Btu -
LP. Care should be taken when sizing the gas
pipe due to the extremely high Btu of this unit.
