High Elevations

Input ratings are shown in BTU per hour and are certified without deration from elevations up to 4,500 feet (1,370m) above sea level.

Nuisance outages may occur at altitudes above 4,500 feet (1,370m) 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 (1,370m)

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 (1,370m)

Pressure Test Points

The gas control is equipped with a captured screw-type pressure test point, therefore it is not necessary to pro- vide a 1/8” test point upstream of the control.

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.

WARNING

This appliance is for installation in a solid-fuel burning masonry, fireplace with a working flue, a U.L.-127 listed manufactured solid-fuel burn- ing fireplace, in any Majestic ventless firebox, or in any listed ventless firebox enclosure certified to I.A.S. U.S. Requirement 2-97 or ANSI Z21.91.

NOTICE

This is an unvented gas-fired heater. It uses air (oxygen) from the room in which it is installed. Provisions for adequate combustion and ventila- tion air must be provided. Refer to Pages 7 and 8.
