Vermont Castings UVS27 Vent-Free Gas Heater
20005004
Operation
Your First Fire
Read these instructions carefully and familiarize
yourself with the burner controls shown on Page 18.
Locate the pilot assembly, Figure 28. Follow the
lighting instructions on Page 17 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 the first eight to
ten hours, 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 patterns are as shown in
Figures 31 and 32. 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 20.
