OPERATING PRECAUTIONS

This is a propane, direct-fired, convection heater. It's intended

use is primarily temporary heating of buildings under

construction, alteration or repair.

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. Read enclosed Odor Fade and Propane

Sheet for additional information about detecting propane leaks.

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 application and

supply installation and ask him to check it if there are any

questions.

This heater was designed and certified for use as a construction

heater in accordance with ANSI Standard Z83.7/CGA 2.14-2000.

Check with your local fire safety authority if you have any

questions about your applications. Other standards govern the

use of fuel gases and heat producting products in specific

applications. Your local authority can advise you about these.

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. 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.

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

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. DO NOT light or operate heater unless the shells are fully

extended and locked into position. See enclosed assembly

sheet for instructions.

4. Use only propane gas.

5. Use only VAPOR WITHDRAWAL propane supply. If there is any

question about vapor withdrawal, ask your propane dealer.

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

Secure them from falling or being knocked over and protect

them from damage.

7. Locate propane containers at least (USA) 7 ft. (2.13m) for

80CV and 9 ft. (2.7m) for 200CV (Canada)10 ft. (3m) from

the heater and do not direct exhaust toward containers.

8. IMPORTANT Use only the hose and regulator assembly

provided with the heater. 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.

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.

9. For indoor use only. Area must be well ventilated. Figure 1.

(also see "Operating Precautions").

10. If at any time gas odor is detected, IMMEDIATELY

DISCONTINUE operation until the source of gas has been

located and corrected. Read enclosed Odor fade and Propane

Sheet for additional information about detecting propane

leaks.

11. Install the heater such that it is not directly exposed to water

spray, rain and/or dripping water.

12. Maintain minimum clearance from normal combustible

material (like paper). Figure 2.

13. Due to the high surface and exhaust temperatures, adults and

children must observe clearances to avoid burns or clothing

ignition.

14. Operate only on a stable, level surface.

15. Do not use with duct work. Do not restrict inlet or exit.

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 and CSA B149.1,

Natural Gas and Propane Installation Code.
