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.

UPON CONNECTION MARK APPROPRIATE FUEL TYPE ON CANADIAN STANDARDS

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
