OPERATING PRECAUTIONS
This is a propane, direct-red, convection 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 tting,
it sinks to the oor, 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 reconnection 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 certied for use as a construction heater in accordance with
ANSI Standard Z83.7/CGA 2.14. Check with your local re safety authority if you have any questions about your
applications. Other standards govern the use of fuel gases and heat producing products in specic 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 efciency, 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. 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.
