Installation & Operation Tips

When placing the heater indoors, the installation space must supply adequate air for both combustion and room ventilation. At minimum, the room should have two permanently open air intake points: one positioned no more than 12 inches (30 cm) from the ceiling and a second no more than 12 inches (30 cm) from the floor. These openings must connect directly to the outdoors, either through an exterior wall or via ductwork, and must comply with the current edition of ANSI Z223.1 (National Fuel Gas Code), CSA B149.1 (Natural Gas and Propane Installation Codes) where applicable, plus any local codes that govern your jurisdiction.
