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.
HIGH ELEVATION
This unit is approved in Canada for altitude 0 
to 4500 ft. (CAN1 2.17-M91).
GAS LINE 
INSTALLATION
The gas line is brought through the right 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.
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.
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 counterclockwise 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.
