LHEDV Series Direct Vent Insert
First Firing
Upon completing the gas line connection, a small
amount of air will be in the lines. When first lighting unit
with pilot light, it will take a few minutes to purge them-
selves of this air. Once the purging is complete, the
pilot and burner will light and operate as indicated in the
instruction manual. Subsequent lightings of the heater
will not require such purging.
When lit for the first time, the appliance will emit a slight
odor for awhile. This is due to paint and lubricants used
in the manufacturing process. After each lighting, vapor
may condense and fog the glass; this moisture disap-
pears within a few minutes of burning.
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to the
Figure 26 and Figure 27 or 28. If any of the flames ap-
pear abnormal call a service person.
