INFORMATION

WARNINGS

WARNING ICON G 001

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 Stor-

age and Handling of Liquefied Petro­leum Gas, ANSI/NFP A 58 and the Natu­ral Gas Installation Code, CAN/CGA
B149.2. This instructs on the safe stor-

age 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 0

• Electrical grounding instructions —
This appliance is equipped with a three­prong (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 0.28 m2 (3
ft.2) 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: 2.50 m (8 ft.)
Sides: 60 cm (2 ft.) Top: 2 m (6 ft.)
Rear: 60 cm (2 ft.)

• Keep heater at least 2 meters (6 feet)
from propane tank(s). Do not point
heater at propane tank(s) within 6
meters (20 feet).

• Keep propane tank(s) below 38˚ C
(100° F).

• 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. Se vere
burns may result. Wait 20 minutes af­ter turning heater off.

• To 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.

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.

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 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 45 kg

(100 lb) tanks needed to run this heater.
Do not operate this product with any tank

smaller than 45 kg (100 lb).

Less gas is vaporized at lower temperatures.
You may need two or more 45 kg (100 lb)
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 temperature rating for
each heater is -29 °C (-20 °F).
