Operating Instructions
The First Firing
On completing the gas line connection, a small amount
of air will be trapped in the gas line. When you first light
the unit with the pilot light, it will take a few minutes to
purge the trapped air. Once you have purged the gas
line, the pilot and burner will light and operate normally.
Subsequent lightings of the appliance will not require
purging the gas line.
When lit for the first time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubri-
cants used in the manufacturing process curing under
heat. This is normal. You may wish to have the windows
open to dissipate any odors during the curing process.
