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. 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 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
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 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.
