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/
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 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.

• 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 and the Propane
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/NFPA 70 or the
Canadian Electrical 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 or extension cord.

• Approved by the New York City Fire
Department under Certificate of
Approval #4953. To be used only at
construction site with applicable New
York City Codes, Regulations, Rules,
Directives, Permits, etc.

• This product has been approved for use
in the Commonwealth of Massachusetts.

• This heater produces carbon monoxide,
which is listed by the State of California as
a reproductive toxin under Proposition 65.

• 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 opening of fresh, outside air
for each 100,000 Btu/Hr of rating.

• 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 in basement or 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 v apors and
liquids.

• Do not use heater in areas with high dust
content. Dust is combustible.

• Minimum heater clearances from
combustible materials:

Outlet: 8 Ft. Sides: 2 Ft.
Top: 6 Ft. Rear: 2 Ft.

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

• Keep propane tank(s) below 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 with hose
specified by manufacturer before using
heater.

• Locate heater on stable and level surface
if heater is hot or operating.

• Never block air inlet (rear) or air outlet
(front) of heater.

• Keep heater away from strong drafts,
wind, 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 or
operating heater. Se vere burns may result.
You must wait 15 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 to 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
automatic control 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 spark trans-
former and ignitor lights the main burner.

The Safety Control System: This sys­tem causes the heater to shut down if the
flame goes out.

Some parts are located differently on

some models.

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 the Propane Installation Code CAN/
CGA B149.2. Your local library or fire de-

partment 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)
