The efficiency rating of the appliance is a
product thermal efficiency rating determined
under continuous operating conditions and
was determined independently of any installed
system.
INSTALLATION
GAS CONNECTION
The gas connection is a 3/8" NPT rigid pipe. This
pipe is supplied separately and must be in-
stalled at the left rear of the unit. See page 2 for
diagram. The gas line can be rigid pipe or to
make installation easier, use a listed flexible
connector and manual shut-off valve if allowed
by local codes, or copper if approved. For
minimum and maximum supply pressure see
the System Data table.
Note: During any pressure testing of the
gas supply piping system that
exceeds test pressures of 1/2
psig, this appliance and its individ-
ual shut-off valve must be discon-
nected from the piping system. If
test pressures equal to or less
than 1/2 psig are used then this
appliance must be isolated from
the piping system by closing its
individual manual shut-off valve
during the testing.

HIGH ELEVATION
This unit is approved in Canada for altitude 0 to
4500 ft. (CAN1 2.17-M90) with the orifice sup-
plied.
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 pres-
sures over 1/2 psig (14" w.c.).
The manifold pressure is controlled by a regu-
lator 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" (# 7) and/or "OUT" (# 6)
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. Screw should be snug,
but do not over tighten.
