WARNING: Only persons licensed to work with gas piping may make the necessary gas connections to
this appliance.
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 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 top right of the valve shown in Figure 42.
• 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.
