Gas Connection

The gas line can be rigid pipe, or to make installation
easier, use a listed flexible connector if allowed by
local codes. Copper may also be used if approved
by local codes.
The gas connection at the valve is 3/8" NPT. For
minimum and maximum supply pressure see the
System Data Table.

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 (14" w.c.).
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
#33
be checked using the valve pressure
ports on the valve.
1. Make sure the valve is in the "OFF" position.
2. Loosen the "IN" (# 7) and/or "OUT" (# 6) pres-
sure tap(s), turning counterclockwise with a
1/8" wide flat screwdriver.
3. Attach manometer to "IN" and/or "OUT" pres-
sure tap(s) using a 5/16" ID hose.
4. Light the pilot and turn the valve to "ON" posi-
tion.

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.
Screw should be snug, but do not over tighten.

On Demand Pilot Light

Important: This appliance has a timer built into
the pilot light.
The timer starts when the main burner has been
shut-off by use of a remote control,thermostat or
on/off switch. The timer is set for 7 days. If there
has not been a call for heat for this 7 day period,
the pilot is designed to extinguish.
See lighting instructions for lighting pilot.
