WARNING: 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 reconnecting 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 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.
WARNING: 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 hang-tag 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 either indoor or outdoor use. Adequate ventilation must be
provided. 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. Maintain minimum clearance from normal combustible material
(like paper). Figure 2.
11.
Due to the high surface and exhaust temperatures, adults and
children must observe clearances to avoid burns or clothing
ignition.
12.
Operate only on a stable, level surface.
13.
Do not use with duct work. 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 (USA) and CSA C22.1 Canadian Electrical Code, Part 1
(Canada).
15.
Use only a properly grounded 3-prong receptacle or extension
cord.
16. Do not move, handle or service while hot or burning.
17.
Do not adjust the heater combustion tube elevation while heater
is running or hot. Adjustments to elevation should only be made
after the heater has cooled to touch.
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.
