Operation
Your First Fire
Read these instructions carefully and familiarize
yourself with the burner controls. Locate the pilot
assembly, Figure 46. Follow the lighting instructions on
Page 28 exactly.
During the first fire, it is not unusual to smell some odor
associated with new logs, paint and metal being
heated. Odors should dissipate within an hour or so,
however, you can open a window to provide fresh air to
alleviate the condition.
Pilot and Burner Inspection
Each time you light your heater check that the pilot
flame and burner flame pattern are as shown in Figure
47 or Figure 48 and Figure 49. If flame patterns are
incorrect, turn the heater off. Contact your dealer or a
qualified gas technician for assistance. Do not operate
the heater until the pilot flame is correct.
Follow regular maintenance procedures as described
on Page 30.
