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 58-1998.Your supplier, fire marshal or library should have a copy.

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 propane 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 one-thirdof con-

tainer capacity.

*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.

SIZE AND CAPACITY OF PROPANE CYLINDERS

The chart below shows the approximate size of the cylinder required for this heater. To use the chart:

1.Select the lowest air temperature expected (at the bottom of the chart).

2.Move straight up to time of operation desired (left side of chart).

3.Read the cylinder size required.

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 assembly 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 well-grounded115V, 60 Hz, 10 source of power.

8.When using an extension cord, make certain that it is a 3-wire(grounded) cord of proper wire size. See chart on page 4.

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

4.When the heater is to be stored indoors, the connection between the LP-gassupply 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/NFPA58-1998.

INSTRUCTIONS FOR ORDERING PARTS

All parts orders must show heater Model No., Item No., Part No., and Description. We recommend that only parts supplied by the manufacturer be used on this unit. A locally purchased part may appear to be identical, although in reality it might endanger the heater or the persons operating the heater.

The heater should be serviced only by a trained, experienced service person.

Read the section on "Servicing" before ordering parts.

For parts order, call (909) 981-5343.

150-FAST/SPC-150T

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. Do not use alternates. For this heater, the regulator must be set to supply 11" water column (W.C.) outlet pressure (.40 psig). If there is any uncertainty about the regulator setting, have it checked.

A heater which is not working right must be repaired, butonly by a trained, experienced service person. Contact the factory for the service center closest to you, phone number(909)981-5343.

You may also obtain in-warrantyorout-of-warrantyservice by returning the product freight prepaid to:

Scheu Products Company

8855 Baker Avenue

Rancho Cucamonga, CA 91730

In-warrantyproducts returned to the Service Department will be repaired with no charge for either parts or labor and will be returned to you freight prepaid. Please include a brief statement indicating date, place of purchase, the nature of the problem and proof of purchase.

Out-of-warrrantyproducts returned to the Service Department will be repaired with a charge for parts and labor and will be returned to you freight collect.

TECHNICAL INFORMATION

HOW MUCH HEAT DO I REQUIRE?

For economy, it is important to match input to that required. But heat requirements often vary. For example, it usually takes a lot more heat to get things warm than it does to keep them that way. Likewise, outside air temperature usually changes during the day so you may need more heat at night than you do in the daytime. An approximation of the heat required can be found by using the chart below.
