PROPANE FUEL PRECAUTIONS
WARNING:
Local codes for installation of propane systems may vary considerably. Therefore, ask your local propane supplier for advice on propane system installation in your particular area. In the absence of local codes, install in accordance with American National Standards Institute (ANSI)/National Fire Protection Association (NFPA) publication Standard for the Storage and Handling of Liquefied Petroleum Gases ANSI/ NFPA
The propane supply system must be arranged for vapor withdrawal. Propane cylinders must be secured in the upright position to keep them from falling or being knocked over.
During use, liquid propane in a container vaporizes. As it vaporizes, the propane cools itself. If this cooling process continues long enough and proceeds fast enough, the pro- pane temperature and pressure will fall so low that heater operation may be improper or even impossible even though plenty of propane remains in the container. Often frost forms on the outside of the propane container as a warning of excessive refrigeration.
Recommendations to reduce the ill effects of refrigeration are:
*Provide considerably more propane than you plan to consume. As a rule of thumb, provide twice as much.
*Fill containers frequently, especially in cold weather. Never allow propane to fall below
*If possible, keep containers in a warm area. Under no circumstances should the heater exhaust be directed toward the propane container.
*Watch for frost formation on the container. If it occurs, discontinue use of the heater and refill the container.

OPERATING INSTRUCTIONS
PREPARING FOR OPERATION
1.Check the heater for possible shipping damage. If any is found, immediately notify your dealer.
2.Follow all of the "Precautions" on pages 2 & 3.
3.Connect the POL fitting of hose and regulator assem- bly to the propane cylinder by rotating the POL nut counterclockwise into the propane cylinder's valve outlet and securely tighten with a wrench.
4.Connect the hose to the heater by rotating the hose fitting clockwise.
5.Securely tighten all gas connections.
6.Open the cylinder's gas valve and check all gas connections with a soap and water solution. DO NOT USE A FLAME.
7.Connect power cord to

START
1.Slowly open the main valve at propane cylinder.
2.Set the thermostat to the desired temperature. Heater will turn on and off automatically as the
temperature varies in the heated areas.
STOP
1.Securely close valve on the propane cylinder.
2.Continue to operate heater until all fuel in the hose has burned.
3.Turn the heater thermostat to off.
RESTARTAFTERSAFETYSHUTDOWN
1.Securely close valve at propane cylinder. Unplug heater.
2.Wait 5 minutes.
3.Restart following "Start" procedure.
MAINTENANCEANDSTORAGE
1.The heater should be inspected before each use, and at least annually by a qualified person.
2.Before each use, check the soft "O" ring seat at the bullnose of the POL fitting. If the "O" ring is cut, scuffed, or otherwise damaged, replace it with part number 6681.
3.Turn off the gas at the
4.When the heater is to be stored indoors, the connec- tion between the
