contains and/or generates
chemicals known to the State
of California to cause cancer or
birth defects or other reproduc-
tive harm.
WARNING: Fire, burn, inha-
lation and explosion hazard.

as building materials, paper or
cardboard, a safe distance away
from the heater as recommended
by the instructions. Never use
the heater in spaces which do or
may contain volatile or airborne
combustibles or products such
as gasoline, solvents, paint thin-
ner, dust particles or unknown
chemicals.
WARNING: Not for home or
recreational vehicle use.
The heater is designed for use as a construction
heater in accordance with ANSI Z83.7/CGA2.14.
Other standards govern the use of fuel gases
and heating products for specific uses. Your lo-
cal authority can advise you about these. The
primary purpose of construction heaters is to
provide temporary heating of buildings under
construction, alteration or repair. Properly used,
the heater provides safe economical heating.
Products of combustion are vented into the area
being heated.
We cannot foresee every use which may be made of
our heaters. Check with your local fire safety au-
thority if you have questions about heater use.
Other standards govern the use of fuel gases and
heat producing products for specific uses. Your
local authorities can advise you about these.
Carbon Monoxide Poisoning: Some people are
more affected by carbon monoxide than others.
Early signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness and/or
nausea. If you have these signs, the heater may not
be working properly. Get fresh air at once! Check
for proper ventilation and have heater serviced.
Propane Gas: Propane gas is odorless. An odor-
making agent is added to propane gas. The odor
helps you detect a propane gas leak. However, the
odor added to propane gas can fade. Propane gas
may be present even though no odor exists.

THEORY OF OPERATION
The Fuel System: The hose/regulator assembly
attaches to the propane gas supply. The propane
gas moves through the solenoid valve and out
the nozzle.
The Air System: The motor turns the fan. The
fan pushes air into and around the combustion
chamber. This air is heated and provides a stream
of clean, hot air.

The Ignition System: The direct spark ignitor
(DSI) sends voltage to the spark plug/ignitor.
The spark plug/ignitor ignites the fuel and air
mixture.
The Safety Control System: This system causes
the heater to shut down if the flame goes out.
PROPANE SUPPLY
Propane gas and propane tank(s) are to be fur-
nished by the user.
Use this heater only with a propane vapor
withdrawal supply system. See Chapter 5 of the
Standard for Storage and Handling of Liquefied
Petroleum Gas, ANSI/NFPA 58. Your local library
or fire department will have this booklet.
The amount of propane gas ready for use from
propane tanks varies. Two factors decide this
amount:
1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 100 pound
(45 kg) tanks needed to run this heater.
Do not operate this product with any tank smaller
than 100 pounds.
Temperature Number
at tank location of tanks
above 20 F (-7 C) 2
20 F (-7 C) to -10 F (-23 C) 3
below -10 F (-23 C) (Use larger tank)
Less gas is vaporized at lower temperatures. You
may need two or more 100 lb. (45 kg) tanks or one
larger tank in colder weather. Your local propane
gas dealer will help you select the proper supply
system. The minimum surrounding-air tempera-
ture rating for each heater is -20 F (-29 C).
