WARNING; Only persons licensed to work with gas piping may make the necessary gas connections to this appliance.
NOTE:
The gas line connection may be made using 3/8" rigid tubing or an approved flex connector. Since some municipalities
have additional local codes it is always best to consult your local authorities and the CAN/CGA-B149 (1 or 2) Installation Code.
For USA gas installations follow either local codes or the current edition of the National Fuel Gas Code ANSI.Z223.1.

The appliance and its individual manual shutoff valves
must be disconnected from the gas supply piping system
during any pressure testing where the pressure exceeds
1/2 PSIG (3.45 kpa) or damage will occur to the valve.
The appliance must be isolated from the gas supply piping
system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psig (3.5
kpa).
When using copper or flex connectors use only fittings
approved for gas connections.
TO TEST
The pressure taps are located in the top right corner on
the valve face (right - inlet, left - manifold pressure).
•
Turn set-screw counter clockwise to loosen, 2 turns.
•
Place 5/16" hose over pressure tap system.
•
When finished, releases pressure, remove hose &
tighten set-screw.
Always check for gas leaks with a soap and water solution
after completing the required pressure test.
NEVER USE AN OPEN FLAME FOR LEAK TESTING
