is primarily temporary heating of buildings under construction,

alteration or repair.

propane is heavier than air. If propane leaks from a connection or

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.

questions about your applications. Other standards govern the use

of fuel gases and heat producing 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.
