A minimum building ventilation rate of 4 CFM per 1,000 BTU of installed heater input must
be provided. This rate of ventilation may be obtained through either gravity or mechanical
ventilation of the building. In conjunction with building ventilation system, adequate fresh
air into the building must be provided through fresh air inlets and/or building inlets. It is
recommended local code be checked to assure the ventilation system and heat installation
are in compliance with local and/or state codes.
Note: Gas connections on the heater are leak tested at the factory prior to shipment.
