OPERATING PRECAUTIONS
WARNING
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. Read enclosed Odor Fade and Propane Sheet for addition-
al information about detecting propane leaks. Leak check new connections or
reconnection's with a soap and water solution.
Direct-Fired means that all of the combustion products enter the heated
space. Even though this heater operates very close to 100 percent combus-
tion 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 inade-
quate ventilation are:
• Headache • Dizziness • Burning eyes and nose • Nausea
• Dry mouth or sore throat
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. Prop-
er 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.
SAFETY PRECAUTIONS
WARNING
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 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 within
20' (6m).
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 as-
sembly 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. Adequate ventilation must be provided. Provide min-
imum openings of 1/2 sq. ft. (.046 m²) near the floor and 1/2 sq. ft. (.046
m²) near the ceiling (also see "Operating Precautions").
9.
If at any time gas odor is detected, IMMEDIATELY DISCONTINUE opera-
tion 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.
11. Maintain minimum clearance from normal combustible material (like
paper) as follows: floor-0 ft. (0 m); outlet-6 ft. (1.83m); sides-4 ft. (.61m);
top-6 ft. (1.83m). Locate 10 ft. (3m) from canvas or plastic tarpaulins or
similar coverings and secure them to prevent flapping or movement due
to wind action.
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 outlet.
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 and CSA B149.1, Natural Gas and
Propane Installation code.
