7. 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.
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 Odor Fade and
Propane information on page 5, for additional information about detecting
propane leaks.
10. Install the heater such that is 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.
15. Use only the electrical power specified. The electrical connection and grounding
must comply with National Electrical Code - ANSI/NFPA 70 (USA) and CSA
C22.1 Canadian Electrical Code, Part 1 (Canada).
16. Use only a properly grounded 3-prong receptacle or extension cord.
17. Do not move, handle or service while hot or burning.
18. 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.
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 (USA) 7 ft. (2.13m), (Canada) 10 ft. (3m) from
the heater and do not direct exhaust toward containers.
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.
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
Be sure to follow advice about ventilation in the Safety Precautions section.
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.
