OPERATING PRECAUTIONS
SAFETY 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 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.
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.
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
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. Provide
minimum 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 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 is 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-2 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 ductwork. 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 (6 ft (1.83m) in length minimum).
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.
