INSTALLATION INSTRUCTIONS
Ventilation
Buildings using high intensity radiant heaters require ventilation. High Intensity type heaters are considered un-
vented gas fired appliances, requiring ventilation to supply combustion air and dilute/remove the products of
combustion.
Requirements for combustion air supply and dilution air vary by jurisdiction, building type and specific installation
details. See local codes for guidance. In general, where heaters are installed without direct outside combustion
air, fresh air ventilation must be provided to building space (3 cfm per 1000 BTU/Hr in Canada, 4 cfm per 1000
BTU/Hr in the USA), Verify applicable local codes in the USA as requirements change by jurisdiction.
• Mechanical exhaust should be electrically interconnected with the heaters and should always be installed
in conjunction with inlet air openings. See “Block Diagram for Interconnecting Fan/Humidistat” above for
details.
• Inlet air opening should be relatively small and distributed over the operating area of the heaters. They
must always be located below the level of the heaters. One square inch of net free inlet area per 1000
btu/h is recommended.
Condensation
The products of combustion for natural gas contain up to 1 liter of water per 100,000 BTU consumed. This may
add substantial amounts of moisture to the building air environment and may become a problem of condensation
on cold surfaces within the building. This is particularly true for poorly insulated metal roof decks or structural
steel framing.
• To decrease condensation, increase mechanical ventilation.
• Ensure that continuous waterproof barriers are used on the inside of all insulated surfaces.
• Ensure that exhausters pull air from the entire space and across the condensing surface.
• Humidistat controls may be integrated into the electrical control circuit of the heaters.
