High Elevations
Input ratings are shown in BTU per hour and are
certified without deration from elevations up to
4,500 feet (1,370 m) above sea level.
Nuisance outages may occur at altitudes above
4,500 feet (1,370 m) if dirt, dust, lint and/or cob-
webs are allowed to accumulate on burner and/or
ODS pilot. Monthly inspection and cleaning is
recommended for altitudes above 4,500 feet
(1,370 m)
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the
current ANSI Z223.1/NFPA 54 and/or local codes
having jurisdiction.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370 m)
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 car-
pet 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.
