OPERATING PRECAUTIONS
This is a propane, direct-fired, forced air heater. It's intended use
is primarily temporary heating of buildings under construction,
alteration or repair.
Propane is heavier than air. If propane leaks from a connection or
fitting, it sinks to the floor, collecting there with the surrounding
air, forming a potentially explosive mixture. Obviously, propane
leaks should be avoided, so set up the propane supply with
utmost care. Read enclosed Odor Fade and Propane Sheet for
additional information about detecting propane leaks. Leak check
new connections or reconnections with a soap and water solution
and follow all connection instructions herein. Also, ask your
propane dealer for advice on the propane application and supply
installation and ask him to check it if there are any questions.
This heater was designed and certified for use as a construction
heater in accordance with ANSI Z83.7/CGA 2.14. Check with
your local fire safety authority if you have any questions about
your applications. Other standards govern the use of fuel gases
and heat producing products in specific applications. Your local
authority can advise you about these.
Direct-Fired means that all of the combustion products enter the
heated space. Even though this heater operates very close to 100
percent combustion efficiency, it still produces small amounts of
carbon monoxide. Carbon monoxide (called CO) is toxic. We can
tolerate small amounts but not a lot. CO can build up in a heated
space and failure to provide adequate ventilation could result in
death.

The symptoms of inadequate ventilation are:
• headache
• dizziness
• burning eyes and nose
• nausea
• dry mouth or sore throat
So, be sure to follow advice about ventilation in these operating
instructions.
Forced Air means that a blower or fan pushes the air through the
heater. Proper combustion depends upon this air flow; therefore,
the heater must not be revised, modified or operated with
parts removed or missing. Likewise, safety systems must not be
circumvented or modified in order to operate the heater.
When the heater is to be operated in the presence of other
people the user is responsible for properly acquainting those
present with the safety precautions and instructions, and of the
hazards involved.
