Dayton® Propane
Construction Heater
Theory of Operation
THE FUEL SYSTEM
The hose/regulator assembly attaches to the propane gas supply. The propane gas moves through the solenoid valve and out the nozzle.
THE AIR SYSTEM
The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air.
THE IGNITION SYSTEM
The direct spark ignitor (DSI) sends voltage to the ignitor, which ignites the fuel and air mixture.
THE SAFETY CONTROL SYSTEM
This system causes the heater to shut
Propane Supply
Propane gas and propane tank(s) must be provided by the user.
Use this heater only with a propane vapor withdrawal supply system. See Chapter 5 of the Standard for Storage and Handling of Liquefied Petroleum Gas, ANSI/NFPA 58. The local library or fire department will have this booklet.
The amount of propane gas ready for use from propane tanks varies. Two factors determine this amount:
1.The amount of propane gas in tank(s)
2.The temperature of tank(s)
The chart below shows the number of 100 pound tanks needed to run this heater.

Less gas is vaporized at lower tempera- tures. You may need two or more 100 pound tanks or one larger tank in colder weather. Your local propane gas dealer will help you select the proper supply system. The minimum
