SAFETY INFORMATION
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 inhalation 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 construction
heater in accordance with ANSI Z83.7•CGA
2.14. Other standards govern the use of fuel
gases and heating products for specific uses.
Your local 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 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 may fade. Propane gas
may be present even though no odor exists.
Make certain you read and understand all warn
ings. 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
dard for Storage and Handling of Liquefied
Petroleum Gas, ANSI/NFPA 58 Natural Gas
Installation Code, CAN/CGA B149.2. This
instructs on the safe storage and handling of
propane gases.
2. This product has been approved for use in the
Commonwealth of Massachusetts.
3. Use only propane gas set up for vapor with
drawal.
4.
Provide adequate ventilation. Before using
heater, provide at least a 2.5 square foot
2
(0.232 m
foot (0.557 m2) (200,000 btu heaters) opening
of fresh, outside air.
5. For indoor use only. Do not use heater out
doors.
6. Keep heater away from strong drafts, wind,
water spray, rain or dripping water.
7. Do not use heater in occupied dwellings or in
living or sleeping quarters.
8. Do not use heater in a basement or below
ground level. Propane gas is heavier than air.
If a leak occurs, propane gas may sink to the
lowest possible level.
9. Keep appliance area clear and free from com
bustible materials, gasoline, paint thinner and
other flammable vapors and liquids. Dust is
combustible. Do not use heater in areas with
high dust content.
11. Keep heater at least six feet (1.83 m) from
propane tank(s).
12. Keep propane tank(s) below 100° F (37.8° C).
13. Use only the hose and factory preset regulator
provided with the heater.
14. Check heater for damage before each use. Do
not use a damaged heater.

PROPANE SUPPLY
You must provide propane gas and propane tank(s).
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 and/or CAN/CGA
B149.2. Your local library or fire department will
have this booklet.
This heater will operate with a 20 pound (9.07 kg)
propane tank. However, you can only operate it in
the LOW position during mildly cool weather for
a very short time. At higher heat settings or during
colder weather, you must use larger tanks.
The amount of propane gas ready for use from pro
pane 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 minimum number of
100 pound (45 kg) tanks needed to run the heater.
Connect tanks together with a manifold.

local propane gas dealer will help you select the
proper supply system.
INSTALLATION
WARNING: Review and understand the warnings in the
Safety Information section, page
2. They are needed to safely operate this heater. Follow all local
codes when using this heater.
CAUTION: Never ignite and/
or run this heater unless the
shells are fully extended and
locked into position.
OUTER SHELL
IMPORTANT: When the heater is first removed
from carton, the outer shell is in the down position. Protect hands before lifting outer shell. Never
grasp bare metal without hand protection.
1. Care must be taken to protect hands during this
step. Lift outer shell straight up as shown in Fig
ure 2, until all three clips engage slots in lower
shell. Screw holes will line up at this point.
2. Lock clips into place with 3 screws as shown
in Figure 2. The heater must not be operated
unless the outer shell is properly extended and
fully locked into place.

CONNECTING TO GAS SUPPLY
WARNING: Test all gas piping
and connections for leaks after
installation or servicing. Never
use an open flame 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 fuel gas fitting on hose/regulator
assembly to propane tank(s). Turn fuel
gas fitting counterclockwise into threads
on tank. Tighten firmly using a wrench.
IMPORTANT: Tighten regulator with vent
pointing down. Pointing vent down protects
regulator from weather damage.
3. Connect hose to the valve inlet. Tighten firmly
using a wrench. You must use the regulator sup
plied with heater even if propane tank has one.
