WARNING: This product
contains and/or generates
chemicals known to the State
of California to cause cancer or
birth defects or other reproductive harm.
WARNING: Fire, burn, in-
halation and explosion hazard.
Keep solid combustibles, such
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 thinner, dust particles or unknown
chemicals.
WARNING: Not for home or
recreational vehicle use.
The heater is designed for use as a con-
struction heater in accordance with ANSI
Z83.7•CGA2.14-2000. Other standa rds
govern the use of fuel gases and heating
products for specic uses. Your local authority can advise you about these. The primary
purpose of construction heaters is to provide
temporary heating of buildings under con-
struction, 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
re safety authority 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
resemble 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.
Make certain you read and understand all
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this heater.
1. Install and use heater with care. Follow
all local ordinances and codes. In the
absence of local ordinances and codes,
refer to the Standard for Storage and
Handling of Liqueed Petroleum Gas,
ANSI/NFPA 58 and the Propane Gas
Installation Code, CAN/CGA B149.2. This
instructs on the safe storage and handling
of propane gases.
2. Use only the electrical voltage and fre-
quency specied on model plate. The
electrical connections and grounding of
the heater shall follow the National Electric

The Fuel System: The hose/regulator assem-
bly attaches to the propane gas supply. This
provides fuel to the heater.
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.

PROPANE SUPPLY
Propane gas and propane tank(s) are to be
furnished 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 Liqueed Petroleum Gas, ANSI/NFPA 58
and/or CAN/CGA B149.2. Your local library or
re 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)
INSTALLATION
WARNING: Review and understand the warnings in the
Safety section, page 2. They are
needed to safely operate this
heater. Follow all local codes
when using this heater.
Hose/Regulator
Assembly
This heater is designed to operate with a
minimum 20 b (9 kg) propane tank. You may
need two or more tanks or one larger tank in
colder weather. It is recommended you use a
100 lb (45 kg) tank for longer operation. See
chart below. Less gas is vaporized at lower
temperatures. Your local propane gas dealer
will help you select the proper supply system.
The minimum surrounding air temperature
rating for each heater is 0° F (-18° C).
Average Temp No. Of Tanks
At Tank Location 100 lb (45 kg)
Above 0° F (-18° C) 1
Below 0° F (-18° C) 2
WARNING: Test all gas piping
and connections for leaks after
installation or servicing. Never
use an open ame to check for
a leak. Apply a mixture of liquid
soap and water to all joints.
Bubbles forming show a leak.
Correct all leaks at once.
1. Provide propane supply system (see
Propane Supply).

2. Connect POL tting on hose/regulator
assembly to propane tank(s). Turn POL
tting counterclockwise into threads on
tank. Tighten rmly using wrench. IM-
PORTANT: Position regulator so that hose
leaving the regulator is in a horizontal position (see Figure 3, page 5). This places
the regulator vent in the proper position
to protect it from the weather.
3. Connect hose to valve inlet (see Figure
4). Tighten rmly using a wrench.
IMPORTANT: Use extra hose or piping
if needed. Install extra hose or piping
between hose/regulator assembly and
propane tank. You must use the regulator
supplied with heater.

from the excess-ow check valve closing.
If this happens, reset the excess-ow
check valve by closing propane supply
valve and open again slowly.
5. Check all connections for leaks. Apply
mixture of liquid soap and water to gas
joints. Bubbles forming show a leak that
