Excalibur ® P95-3 Zero Clearance Direct Vent Gas Fireplace 23
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 pressures
over 1/2 psig.
For USA installations follow local codes and/or
the current National Fuel Gas Code, ANSI
Z223.1.
When using copper or fl ex connectors use only
approved fi ttings. Always provide a union so
that gas lines can be easily disconnected for
servicing. Flare nuts for copper lines and fl ex
connectors are usually considered to meet this
requirement.
Important: Always check for gas leaks with a
soap and water solution or gas leak detector.
Do not use open fl ame for leak testing.
PILOT ADJUSTMENT
Periodically check the pilot fl ames. Correct
fl ame pattern has three strong blue fl ames:
1 fl owing around the thermopile, 1 around
the thermocouple and 1 fl owing across the
burner (it does not have to be touching the
burner).
Note: If you have an incorrect fl ame pattern,
contact your Excalibur ® dealer for
further instructions.
Incorrect fl ame pattern will have small,
probably yellow fl ames, not coming into
proper contact with the rear burner or
thermopile or thermocouple.
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 counter clockwise with a
1/8" wide fl at 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 specifi ed on the safety
label.
6) When fi nished reading manometer, turn
off the gas valve, disconnect the hose and
tighten the screw (clockwise) with a 1/8" fl at
screwdriver. Note: Screw should be snug,
but do not over tighten.

INSTALLATION
HIGH ELEVATION
This unit is approved in Canada for altitude
0 to 4500 ft. (CAN1 2.17-M91) & U.S.A ANSI
ZZ1.88a
GAS LINE
INSTALLATION
The gas line is brought in through the left side
of the appliance. The gas valve is situated on
the right hand side of the unit and the gas inlet
is on the right hand side of the valve.
Note: When the gas line is being installed
from the left side, be sure to leave
room to accommodate servicing of
the fan.
The gas line connection may be made of rigid
pipe, copper pipe or an approved fl ex connector.
(If you are using rigid pipe, ensure that the valve
can be removed for servicing.) Since some
municipalities have additional local codes it is
always best to consult with your local authorities
and the CAN/CGA B149 installation code.
