SAFETY
INFORMATION
WARNINGS
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•CGA2.14. 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
warnings. Keep this manual for reference. It
is your guide to safe and proper operation of
this heater.
• 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 Liquefied
Petroleum Gas, ANSI/NFPA 58 andthe Natural Gas Installation Code,
CAN/CGA B149.2. This instructs on
the safe storage and handling of propane gases.
• Use only the electrical voltage and
frequency specified on model plate.
• The electrical connections and
grounding of the heater shall follow
the National Electric Code, ANSI/
NFP A 70 or Canadian Electric Code,
Part 1.
• Electrical grounding instructions —
This appliance is equipped with a
three-prong (grounding) plug for
your protection against shock hazard
and should be plugged directly into
a properly grounded three-prong receptacle.
• Use only a three-prong, grounded
extension cord.
• Use only the hose and factory preset
regulator provided with the heater.
• Use only propane gas set up for vapor withdrawal.
• Provide adequate ventilation. Before
using heater, provide at least a threesquare-foot (0.28 m2) opening of
fresh, outside air for each 100,000
Btu/Hr of rating. This heater produces carbon monoxide, which is
listed by the State of California as a
reproductive toxin under Proposition
65.
• For indoor use only. Do not use
heater outdoors.
• Do not use heater in occupied dwellings or in living or sleeping quarters.
• Do not use heater below ground
level. Propane gas is heavier than air.
If a leak occurs, propane gas will sink
to the lowest possible level.
• Keep appliance area clear and free
from combustible materials, gasoline, paint thinner, and other flammable vapors and liquids. Do not use
heater in areas with high dust content.
• Minimum heater clearances from
combustibles:
Outlet: 8 Ft. (2.5 m)Sides: 2 Ft. (60
cm) Top: 6 Ft. (2 m) Rear: 2 Ft.
(60 cm)
• Keep heater at least six feet (2 m)
from propane tank(s). Do not point
heater at propane tank(s) within 20
feet (6 m).
• Keep propane tank(s) below 100°F
(38°C).
• Check heater for damage before each
use. Do not use a damaged heater.
• Check hose before each use of heater.
If highly worn or cut, replace before
using heater.
• Locate heater on stable and level surface if heater is hot or operating.
• Not intended for use on finished
floors.
• Never block air inlet (rear) or air outlet (front) of heater.
• Keep heater away from strong drafts,
water spray, rain, or dripping water.
• Do not leave heater unattended.
• Keep children and animals away
from heater.
• Never move, handle, or service a hot,
operating, or plugged-in heater. Severe burns may result. Wait 20 minutes after turning heater off.
• T o prevent injury , wear gloves when
handling heater.
• Never attach duct work to heater.
• Do not alter heater. Keep heater in
its original state.
• Do not use heater if altered.
• Turn off propane supply and unplug
heater when not in use.
• Use only original replacement parts.
This heater must use design-specific
parts. Do not substitute or use generic
parts. Improper replacement parts
could cause serious or fatal injuries.
• Do not adjust regulator below 7 psig
(48 kPa) or above 20 psig (138 kPa).

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 ignitor.
The ignitor ignites the fuel and air mixture.
The Safety Control System: This system causes the heater to shut down if the
flame goes out. The motor will continue to
run, but no heat is produced.

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
Liquefied Petroleum Gas, ANSI/NFPA 58
and/or CAN/CGA B149.2. Your local li-
brary 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 (45 kg).

VENTILATION
WARNING: Follow the minimum fresh, outside air ventilation requirements. If proper fresh,
outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper
fresh, outside air ventilation before running heater.
Provide at least three square feet (0.28 m2) of
fresh, outside air for each 100,000 Btu/Hr of
rating. This heater requires a fresh air opening of at least 11.25 square feet (1.05 m2).
Provide extra fresh air if more heaters are
being used.

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.
6.Make sure regulator is set between 7
and 20 psig (48 and 138 kPa).
Note:
Higher regulator setting will al-
low heater to produce more heat.
WARNING: Do not adjust
regulator below 7 psig (48 kPa) or
above 20 psig (138 kPa) . Heater
may not run properly.
7.Turn on/off switch to the ON position.
Heater will start within six seconds.
Note:
If heater does not start, turn on/
off switch to the OFF position. W ait ten
seconds for safety control to reset, then
try again.

propane tank(s). Allow heater to burn
remaining fuel in hose.
2.Wait a few seconds. Heater will burn
gas left in supply hoses.
3.Turn on/off switch to the OFF position.
4. Unplug heater.
STORAGE
CAUTION: Disconnect heater
from propane supply tank(s).
1.Store propane tank(s) in safe manner.
See Chapter 5 of Standard for Storage
