GAS LINE CONNECTION
• This stove is equipped with a certified flexible pipe
located on the right side of the unit terminating in a ⅜”
male NPT fitting. Consult your local authorities codes or
the CAN/CGA B 149 (1 or 2) installation code in Canada,
or in the USA gas installations follow either local codes
or the current edition of the National Fuel Gas Code ANSI
Z223.1.
• The efficiency rating of this appliance is a product
of the thermal efficiency rating determined under
continuous operating conditions and was determined
independently of any installed system.
The appliance and its shutoff valves must be disconnected from the gas supply piping system during any
pressure testing where the pressure exceeds ½ 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
½ psig (3.45 KPa).
Always check for gas leaks with a soap and water solution after completing the
required pressure test.
TO TEST VALVE PRESSURES
The pressure taps are located on the left side of the valve
• Turn set screw 1 turn counter clockwise to loosen,
• Place 5 /
16
” (8 mm) I.D. hose over pressure tap system.
• Check pressures using a manometer.
• When finished, release pressure, remove hose & tighten set screw.
