12) VENTILATION

Failure to do so may result in death, serious injury, property

damage or illness from Carbon Monoxide poisoning.

Heaters installed in an unvented mode require a minimum

ventilation flow of 4 CFM per 1,000 Btu/hr of total installed

capacity.

CARBON MONOXIDE HAZARD

Where unvented infrared heaters are used, natural or mechanical means shall be provided to supply and exhaust

at least 4 cfm per 1000 Btu per hr input of installed heaters.

Exhaust openings for removing flue products shall be above the level of the heaters.

This heater requires ventilation in the building to dilute the product of combustion and provide fresh air for

efficient combustion. Power ventilation is recommended, and the minimum vent flow required is as follows:

SGM3 = 109 cfm SGM6 = 218 cfm SGM10 = 436 cfm

If gravity ventilation is used, the required square feet of inlet and outlet vent area (depending on height and

temperature difference) is as follows:

SGM3 = 0.4 s/f SGM6 = 0.8 s/f SGM10 = 1.6 s/f

The General Ventilation Rules outlined in the ASHRAE GUIDE AND DATA BOOK should be observed when locating

vents. Exhaust vents must be located at the highest point above and in the vicinity of the heaters and the inlet

nets must be located below the level of the heaters.
