3.Restart following "START" procedure.

MAINTENANCE AND STORAGE

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 LP-gas supply cylinder(s) when the heater is not in use.

4.When the heater is to be stored indoors, the connection between the LP-gas supply cylinder(s) and the heater must be disconnected and the cylinder(s) removed from the heater and stored out of doors and in accordance with Chapter 5 of the standard for Storage and Handling of Liquefied Petroleum Gases ANSI/NFPA 58 and CSA B149.1, Natural Gas and Propane Installation Code.

SERVICING

A hazardous condition may result if a heater is used that has been modified or is not functioning properly. When the heater is working properly:

*The flame is contained within the heater.

*The flame is essentially blue with perhaps some yellow tipping.

*There is no strong disagreeable odor, eye burning or other physical discomfort.

*There is no smoke or soot internal or external to the heater.

*There are no unplanned or unexplained shut downs of the heater.

The parts lists and exploded view show the heater as it was constructed. Do not use a heater which is different from that shown. In this regard, use only the hose, regulator and cylinder connection fitting (called a POL fitting) supplied with the heater. IMPORTANT Match the color stripe on the hangtag attached to the hose assembly with the color on the label located near the propane inlet fitting on the heater. Do not use alternates. For this heater, the regulator must be set as shown in "specifications". If there is any uncertainty about the regulator setting, have it checked.

A heater which is not working right must be repaired, but only by a trained, experienced service person.

In-warranty products will be repaired with no charge for either parts or labor. Please include a brief statement indicating date, place of purchase, the nature of the problem and proof of purchase.

Out-of-warrranty products will be repaired with a charge for parts and labor.
