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.
