High Altitude Canada 0-4500 ft. (1372m), in the USA follow ANSI Z223.1

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 RATING LABEL LOCATED

ON THE INSIDE OF THE RIGHT HAND SIDE PANEL.

Pilot Adjustment screw. "HI-LOW" Burner Gas Knob. Pilot "ON-OFF" Gas Knob.

The appliance and its 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 setscrew counter clockwise to loosen, 2 turns.

•Place 5/16" hose over pressure tap system.

•When finished, release pressure, remove hose & tighten setscrew.

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
