Mr. Heater Direct Fired Force Air Heater
Mr. Heater Direct Fired Forced Air Heaters generate heat when the internal blower or fan pushes air through the heater. The heating process intakes air surrounding the unit and turns it into warm air, which then surrounds people and objects with “atmospheric” warmth. Imagine a warm tropical breeze! With the inclusion of a blower, the warmed air is forced into the heated space, providing a constant flow of heater air.

Proper combustion depends upon 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.

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.

This heater was designed and certified for use as a construction heater in accordance with ANSI Standard Z83.7/CGA 2.14-2000. 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.
