GasPipePressureTesting
It is necessary to isolate the unit from the gas supply
piping system prior to gas pipe pressure testing.
Close the unit's manual shut-off valve during test
-
ing at pressures equal to or less than 1/2 psig.
(3.45 kPa). Disconnect the piping from the 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.
HighElevation
This unit is approved for altitude 0 to 4,500 ft.
Gas Line Installation
Some municipalities have local codes for gas line
installation. 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 installing copper or flex connectors, use
approved fittings only. Flare nuts for copper lines
and flex connectors usually meet this requirement.
Provide a union for easy disconnection of gas lines
when servicing.
An incorrect flame pattern will have small, probably
yellow flames, not coming into proper contact with
the rear burner or flame sensor.
PilotAdjustment
Periodically check the pilot flames. A correct flame
pattern has two strong blue flames: one flowing
around the flame sensor and one flowing across the
burner (it does not have to be touching the burner).

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 unit 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" or "OUT" pressure
tap(s) using a 5/16" ID hose.
4. Turn the unit on using the remote or wall switch.
5. Do the pressure check with the unit burning.
The setting should be within the limits specified
on the safety label.
