(1,370 m) if dirt, dust, lint and/or cobwebs are allowed
Fully to accumulate on burner and/or ODS pilot. Monthly
Closed inspection and cleaning is recommended for altitudes
above 4,500 feet (1,370 m)
N/A
For elevations above 4,500 feet (1,370 m), installations
must be in accordance with the current ANSI Z223.1/
NFPA 54 and/or local codes having jurisdiction.
Improper installation, adjustment, alteration, service or
maintenance can cause injury or property damage. Refer
to this manual for correct installation and operational
procedures. For assistance or additional information
consult a qualified installer, service agency, or the gas
supplier.
H. Odor During Operation
Neither natural gas nor propane gas give off an odor when
burned. The nature of a vent free combustion system,
however, is such that odors may occasionally be produced
during heater operation when impurities exist in the immediate
area. Cleaning solutions, paint, solvents, cigarette smoke,
candles, adhesives, 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.
