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 flame for leak testing.
PILOT ADJUSTMENT
Periodically check the pilot flames. Correct flame pattern has three strong blue flames: 1 flowing around the thermopile, 1 around the thermocouple and 1 flowing across the burner (it does not have to be touching the burner).
Note: If you haveanincorrectflamepattern, contact your Excalibur® dealer for further instructions.
Incorrect flame pattern will have small, probably yellow flames, not coming into proper contact with the rear burner or thermopile or thermocouple.
Themanifoldpressureiscontrolledbyaregulator 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.

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 flex 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.
