INSTAllATION
Since some municipalities have additional local
codes it is always best to consult with your local
authorities.
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
supplied 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 detec-
tor. Do not use open flame for leak testing.

GAS pIpE pRESSURE
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
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.
Located on the right
side of the firebox.

TESTING
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" (3.175 mm) wide flat screwdriver.
3) Attach manometer to "IN" and/or "OUT"
pressure tap(s) using a 5/16" (7.9 mm) 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" (3.175 mm) flat
screwdriver. Note: Screw should be snug,
but do not over tighten.
