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.
!
WARNING
NOT FOR HOME OR RECREATIONAL VEHICLE USE
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. 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 supply installation and ask him to check it if
there are any questions.
Direct-Fired means that all of the combustion products enter
the heated space. Even though this heater operates very
close to 100 percent combustion efficiecy, 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 7 ft. from the
heater and do not direct exhaust toward containers.
7. Use only the hose and regulator assembly provided
with 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 3 sq. ft. near the floor
and 3 sq. ft. 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.
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.;outlet-8 ft.; sides-2 ft.; top-3 ft. Locate 10 ft.
from canvas or plastic tarpaulins or similar coverings
and secure them to prevent flapping or movement
due to wind action.
12. Operate only on a stable, level surface.
13. Do not use with ductwork. Do not restrict inlet or exit.
14. Use only the electrical power specified. The electrical connection and grounding must comply with
National Electrical Code - ANSI/NFPA 70.
15. Use only a properly grounded 3-prong receptacle or
extension cord.
16. Do not move, handle or service while hot or burning.
17. 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 58-1998.
