DYNA-GLO PROPANE FORCED AIR CONSTRUCTION HEATERS
This is a direct-red forced air construction heater for either indoor construction or outdoor use. Its intended 
use is primarily the temporary heating of buildings or structures under construction, alteration or repair. All the 
products of combustion generated by the heater are forced through the heater and released into the area being 
heated. This heater operates at approximately 99%+ combustion efciency but still produces a small amount 
of carbon monoxide. Humans can tolerate small amounts of carbon monoxide for short periods. Carbon 
monoxide can build up in a heated space and failure to provide adequate ventilation could result in poisoning 
or death.
Other standards govern the use of fuel gases and heat producing products in specic applications.
Your local authority can advise you about these.
IMPORTANT: READ THIS USER’S MANUAL CAREFULLY AND COMPLETELY BEFORE TRYING 
TO OPERATE OR SERVICE THIS HEATER. IMPROPER USE OF THIS HEATER CAN CAUSE 
SERIOUS INJURY OR DEATH FROM FIRE, EXPLOSION AND CARBON MONOXIDE POISONING.
NEVER LEAVE THE HEATER
