CONSTRUCTION HEATER

YOUR SAFETY IS IMPORTANT TO YOU AND TO

OTHERS, SO PLEASE READ THESE INSTRUCTIONS

BEFORE YOU OPERATE THIS HEATER.

GENERAL HAZARD WARNING:

FAILURE TO COMPLY WITH THE PRECAUTIONS AND

INSTRUCTIONS PROVIDED WITH THIS HEATER, CAN

RESULT IN DEATH, SERIOUS BODILY INJURY AND

PROPERTY LOSS OR DAMAGE FROM HAZARDS OF

FIRE, EXPLOSION, BURN, ASPHYXIATION, AND

CARBON MONOXIDE POISONING.

ONLY PERSONS WHO CAN UNDERSTAND AND

FOLLOW THE INSTRUCTIONS SHOULD USE OR

SERVICE THIS HEATER.

IF YOU NEED ASSISTANCE OR HEATER INFORMATION

SUCH AS AN INSTRUCTIONS MANUAL, LABELS, ETC.

CONTACT THE MANUFACTURER.

WARNING: FIRE, BURN, INHALATION,

AND EXPLOSION HAZARD. KEEP SOLID

COMBUSTIBLES, SUCH AS BUILDING MATERIALS,

PAPER OR CARDBOARD, A SAFE DISTANCE AWAY

FROM THE HEATER AS RECOMMENDED BY THE

INSTRUCTIONS. NEVER USE THE HEATER IN SPACES

WHICH DO OR MAY CONTAIN VOLATILE OR AIRBORNE

COMBUSTIBLES, OR PRODUCTS SUCH AS GASOLINE,

SOLVENTS, PAINT THINNER, DUST PARTICLES OR

UNKNOWN CHEMICALS.

OPERATING INFORMATION

Intended use is primarily the temporary heating of buildings under construction, alteration or repair.

WARNING

NOT FOR HOME OR RECREATIONAL VEHICLE USE.

This is a propane, direct-fired heater.

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 efficiency, it still produces small amounts of carbon monoxide. Carbon monoxide (called CO) is toxic.

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.

SAFETY PRECAUTIONS

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

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

3. Use only propane gas.

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

5. Mount the propane cylinders vertically (shutoff valve up).

Secure them from falling or being knocked over and protect them from damage.

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

7. 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. 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

Information").

9. 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 or wind.

11. Maintain minimum clearance from normal combustible material (like paper) of 6 ft. in all directions. 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 on combustible floors.

14. Caution: Do not touch heater surface during operation or for 30 minutes after shutdown. It can cause serious burns.

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

16. 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.

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.

* 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 shutdowns of the heater.

The parts list shows 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" W.C. pressure. If there is any uncertainty about the regulator setting, have it checked.

PROPANE FUEL INFORMATION

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.

SIZE AND CAPACITY OF PROPANE

The chart below shows the approximate number of cylinders 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 number of cylinders required. Rather than using several 100-lb. cylinders, it may be preferable to use a larger container installed outside (consult your propane supplier).

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.

NOTE: The chart applied only when you have:

* Full cylinders, 100-lbs. capacity

* Good air circulation

* No frost on cylinders (Note: If frost accumulates on cylinders, divide maximum operating time on chart by 3.) GENERAL INFORMATION

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 container capacity.

* If possible, keep containers in a warm area. Under no circumstances should the heater exhaust be directed toward the propane cylinder.

* If particularly cold weather is expected, install a vaporizer (consult your propane supplier).

* Watch for and avoid frost formation on containers. If it occurs, discontinue use of the heater and refill container.
