• Refer to Reference Section 3 for location of gas line
access in appliance.
• Gas line may be run through knockout(s) provided.
• The gap between supply piping and gas access hole
may be caulked with caulk with a minimum of 300 ºF
(149 ºC) continuous exposure rating or stuffed with
non-combustible, unfaced insulation to prevent cold air
infiltration.
• Ensure that gas line does not come in contact with outer
wrap of the appliance. Follow local codes.
• Pipe incoming gas line into valve compartment.
• Connect incoming gas line to the 1/2 in. (13 mm)
connection on manual shutoff valve.
