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 cylinder vertically (shutoff valve
up). Secure it from falling or being knocked over and
protect them from damage.
6. Locate heater at least 7 ft. from the propane container
and do not direct exhaust toward container.
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 4 sq. ft. near the floor
and 4 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-10 ft.; sides-3 ft.; top-5 ft. Locate 12 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 gounding 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.

SIZE AND CAPACITY OF PROPANE CYLINDERS
To insure correct heater operation use a 500 gallon
cylinder or vaporizer.
WARNING: FIRE, BURN, INHALATION, AND EX-
PLOSION HAZARD. KEEP SOLID COMBUSTIBLES, SUCH
AS BUILDING MATERIALS, PAPER OR CARDBOARD, A
SAFE DISTANCE AWAY FROM THE HEATER AS RECOMMENDED BY THE INSTUCTIONS NEVER USE THE HEATER
IN SPACES WHICH DO OR MAY CONTAIN VOLATILE OR
AIRBORNE COMBUSTIBLES, OR PRODUCTS SUCH AS
GASOLINE, SOLVENTS, PAINT THINNER, DUST PARTICLES OR UNKNOWN CHEMICALS.

PROPANE FUEL PRECAUTIONS
WARNING:
Local codes for installation of propane systems may vary
considerably. Therefore, ask your local propane supplier for
advice on propane system installation in your particular area.
In the absence of local codes, install in accordance with
American National Standards Institute (ANSI)/National Fire
Protection Association (NFPA) publication Standard for the
Storage and Handling of Liquefied Petroleum Gases ANSI/
NFPA 58-1998. Your supplier, fire marshal or library should
have a copy.
The propane supply system must be arranged for vapor
withdrawal. The propane cylinder must be secured in the
upright position to keep it from falling or being knocked over.
During use, liquid propane in a container vaporizes. As it
vaporizes, the propane cools itself. If this cooling process
continues long enough and proceeds fast enough, the propane temperature and pressure will fall so low that heater
operation may be improper or even impossible even though
plenty of propane remains in the container. Often frost forms
on the outside of the propane container as a warning of
excessive refrigeration.
Recommendations to reduce the ill effects of refrigeration are:
* Provide considerably more propane than you plan to
consume. As a rule of thumb, provide twice as much.
* Fill containers frequently, especially in cold weather.
Never allow propane to fall below one-third of container capacity.
* If possible, keep container in a well ventilated area.
Under no circumstances should the heater exhaust be
directed toward the propane container.
* Watch for frost formation on the container. If it
occurs, discontinue use of the heater and refill the
container.
ASSEMBLY INSTRUCTIONS - 7000-FACV HANDLE

the heater.
* There are no unplanned or unexplained shut
downs of the heater.
TECHNICAL INFORMA TION
HOW MUCH HEAT DO I REQUIRE?
For economy, it is important to match input to that
required. But heat requirements often vary. For example, it usually takes a lot more heat to get things warm
than it does to keep them that way. Likewise, outside air
temperature ususally changes during the day so you may
need more heat at night than you do in the daytime. An
approximation of the heat required can be found by using
the chart below.
The parts lists and wiring diagram show the heater as it was
constructed. Do not use a heater which is different from
that shown. In this regard, use only the hose, regulator and
cylinder connection fitting (called a POL fitting) supplied
with the heater. Do not use alternates. For this heater, the
regulator must be set to supply 20 psig outlet pressure. If
there is any uncertainty about the regulator setting, have
it checked.
A heater which is not working right must be repaired, but
only by a trained, experienced service person. Contact the
factory for the service center closest to you, phone number
(909) 981-5343.
You may also obtain in-warranty or out-of-warranty service
by returning the product freight prepaid to:
