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 2.14-2000. 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, 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
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. 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.
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.
