WARNING: Follow the mini- mum fresh, outside air ventilation requirements. If proper fresh, out- side air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, out- side air ventilation before running heater.

Provide a fresh air opening of at least 2800 square cm (three square feet) for each 100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.

Example: A 150,000 Btu/Hr heater requires one of the following:

•a two-car garage door [4.9 m (16 ft.) open- ing] raised 9 cm (3.5 inches)

•a single-car garage door [2.75 m (9 ft.) opening] raised 15.25 cm (6 inches)

•two, 76 cm (30 inch) windows raised 28 cm (11 inches)
