Heater Specications
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. Leak check new connections or reconnections with a soap and water
solution applied to connection: look for bubbles, listen for hiss of escaping gas, feel
for extreme cold, smell for rotten egg odor. Do not use if leaking! 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 Standard 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.
