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 wiring diagram 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.

This heater is equiped with an elevation adjustment panel located at the exhaust end of the control box.

1.Do not adjust the heater combustion tube elevation while heater is running or hot. Adjustments to elevation should only be made after the heater has cooled to touch.

2.To adjust the heater combustion tube elevation, turn the adjustment screw knob counterclockwise and lift the combustion tube to desired position.
