Odor During Operation
Neither natural gas nor LP gas give off an odor when
burned. The nature of a vent free combustion
system, however, is such that odors may occasion-
ally be produced during heater operation when
impurities exist in the immediate area. Cleaning
solutions, paint, solvents, cigarette smoke, adhe-
sives, new carpet or textiles, etc., all can create
fumes. These fumes may mix with combustion air
and can create odor. Such odors will disappear over
time, however, the condition can be alleviated by
opening a window or otherwise providing additional
ventilation to the area.
If odors persist and you are unable to locate the
source, contact a qualified gas service technician.
