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.

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. 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 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.
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, 

Safety Precautions

   WARNING

   WARNING

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.

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 (USA) 7 ft. (2.13m), (Canada) 10 ft. (3m)
from the heater and do not direct exhaust toward containers.

7.

IMPORTANT Use only the hose and regulator assembly provided with the
heater. Match the color stripe on the hang tag 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.

8.

For indoor use only. Area must be well ventilated. Figure 1. (also see “Operating
Precautions”).

9.

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.

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).

Figure 2.

12. Due to the high surface and exhaust temperatures, adults and children must

observe clearances to avoid burns or clothing ignition.

13. Operate only on a stable, level surface.
14. Do not use with duct work. Do not restrict inlet or exit.
