UNPACKING
1. Remove all packing items applied to heater for shipment. Keep
plastic cover caps (attached to inlet connector and hose/regu-
lator assembly) for storage.
2. Remove all items from carton.
3. Check all items for shipping damage. If heater is damaged,
promptly inform dealer where you bought heater.
THEORY OF OPERATION
The Fuel System: The hose/regulator assembly attaches to the
propane gas supply. This provides fuel to the heater.
The Ignition System: The piezo ignitor lights the burner.
The Automatic Control System: This system causes the heater to
shut down if the flame goes out.
NOTICE: Because of the metal lubricant used in this
product, you may notice some smoking upon initial
startup and shut down. This condition is normal and
should not occur beyond the first several (5-10)
minutes of operation. If you have questions, please
call 1-866-672-6040.
PROPANE SUPPLY
Propane gas and propane tank(s) are to be furnished 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. Your local library or fire
department will have this booklet.
The amount of propane gas ready for use from propane tanks varies.
Two factors decide this amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
This heater is designed to operate with a minimum 20 lb. (9 kg) tank.
You may need two or more tanks or one larger tank in colder weather.
Use a 100 lb. (45 kg) tank for longer operation or in very cold weather.
Less gas is vaporized at lower temperatures. Your local propane gas
dealer will help you select the proper supply system.
