OPERATING PRECAUTIONS

This is a propane, direct-fired, forced air heater. It's intended use is primarily temporary heating of buildings under construction, alteration or repair.

!

WARNING

NOT FOR HOME OR RECREATIONAL VEHICLE USE

Propane is heavier than air. If propane leaks from a connection or fitting, it sinks to the floor, collecting there with the surrounding air, forming a potentially explosive mixture. Obviously, propane leaks should be avoided, so set up the propane supply with utmost care. Leak check new connections or reconnections with a soap and water solution and follow all connection instructions herein. Also, ask your propane dealer for advice on the propane supply installation and ask him to check it if there are any questions.

Direct-Fired means that all of the combustion products enter the heated space. Even though this heater operates very close to 100 percent combustion efficiecy, it still produces small amounts of carbon monoxide. Carbon monoxide (called

CO) is toxic. We can tolerate small amounts but not a lot. CO can build up in a heated space and failure to provide adequate ventilation could result in death. The symptoms of inadequate ventilation are: headache dizziness burning eyes and nose nausea dry mouth or sore throat

So, be sure to follow advice about ventilation in these operating instructions.

Forced Air means that a blower or fan pushes the air through the heater. Proper combustion depends upon this air flow; therefore, the heater must not be revised, modified or operated with parts removed or missing. Likewise, safety systems must not be circumvented or modified in order to operate the heater.

When the heater is to be operated in the presence of other people the user is responsible for properly acquainting those present with the safety precautions and instructions, and of the hazards involved.

SAFETY PRECAUTIONS

6.

7.

Check the heater thoroughly for damage. DO NOT operate a damaged heater.

DO NOT modify the heater or operate a heater which has been modified from its original condition.

Use only propane gas.

Use only VAPOR WITHDRAWAL propane supply. If there is any question about vapor withdrawal, ask your propane dealer.

Mount the propane cylinders vertically (shutoff valve up). Secure them from falling or being knocked over and protect them from damage.

Locate propane containers at least 7 ft. from the heater and do not direct exhaust toward containers.

Use only the hose and regulator assembly provided with the heater. Inspect hose assembly before each use of the heater. If there is excessive abrasion or wear, or hose is cut, replace with hose assembly listed on parts list before using heater.

8.

9.

For indoor use only. Area must be well ventilated.

Provide minimum openings of 2 sq. ft. near the floor and 2 sq. ft. near the ceiling (also see "Operating

Precautions").

If at any time gas odor is detected, IMMEDIATELY

DISCONTINUE operation until the source of gas has been located and corrected.

10.

Install the heater such that it is not directly exposed to water spray, rain and/or dripping water.

11.

Maintain minimum clearance from normal combustible material (like paper) as follows: floor-0 ft.;outlet-6 ft.; sides-1 ft.; top-3 ft. Locate 10 ft.

from canvas or plastic tarpaulins or similar coverings and secure them to prevent flapping or movement due to wind action.

12.

Operate only on a stable, level surface.

13.

Do not use with ductwork. Do not restrict inlet or exit.

14.

Use only the electrical power specified. The electrical connection and grounding must comply with

National Electrical Code - ANSI/NFPA 70.

15.

Use only a properly grounded 3-prong receptacle or extension cord.

16.

Do not move, handle or service while hot or burning.

17.

Use only in accordance with local codes or, in the absence of local codes, with the Standard for the

Storage and Handling of Liquefied Petroleum Gases

ANSI/NFPA 58-1998.

WARNING: FIRE, BURN, INHALATION, AND EX-

PLOSION HAZARD. KEEP SOLID COMBUSTIBLES, SUCH

AS BUILDING MATERIALS, PAPER OR CARDBOARD, A

SAFE DISTANCE AWAY FROM THE HEATER AS RECOM-

MENDED BY THE INSTUCTIONS NEVER USE THE HEATER

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-third of 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.

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, but

only by a trained, experienced service person. Contact the factory for the service center closest to you, phone number

(909) 981-5343.

In-warranty products 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-warrranty products 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.
