WARNING

Follow the minimum fresh, outside air ventilation require-
ments.  If proper fresh, outside air ventilation is not provided,
carbon monoxide poisoning can occur. Provide proper fresh,
outside air ventilation before running heater.

VENTILATION

Example:

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

• a two-car garage door raised six inches
• a single-car garage door raised nine inches
• two thirty-inch windows raised twelve inches

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

!

WARNING

Never use an open flame to check for a leak. Apply a mixture
of liquid soap and water to all joints. Bubbles forming show a
leak. Correct all leaks at once.
