IMPORTANT INFORMATION! READ FIRST

The heater is designed for use as a construction heater under ANSI Z83.7a-1993. Heater is not
intended for use in pest remediation. The primary purpose of construction heaters is to provide
temporary heating of buildings under construction, alteration, or repair and to provide emer­gency heat. Properly used, the heater provides safe, economical heating. Products of combustion
are vented into the area being heated.

The heater

SHOULD NOT

ANSI A119.2(NFPA 501C)-1987 Recreational Vehicle Standard prohibits the installation or stor­age of LP-gas containers even temporarily inside any recreational vehicle. The standard also pro­hibits the use of Unvented Heaters in such vehicles.

Use of the heater must be in accordance with this Standard and in compliance with all governing
state and local codes. Storage and handling of propane gas and propane cylinders must be in
accordance with NFPA 58 and all local governing codes.

We cannot anticipate every use which may be made for our heaters. CHECK WITH YOUR

LOCAL FIRE SAFETY AUTHORITY IF YOU HAVE QUESTIONS ABOUT LOCAL REGULATIONS.

Other standards govern the use of fuel gases and heat producing products in specific applica­tions. Your local authority can advise you about these.

repairs by other entities will not be considered. Warranty claims must include model number and serial
number.

LIMITATIONS

Warrant claims for service parts (wear parts) such as spark plugs, igniters, flame rods will not be allowed.
Diagnostic parts such as voltage meters and pressure gauges are not warrantable.

Evidence of improper fuel usage, fuel pressures outside of manufacturer’s specification, poor fuel quality,
and improper electric power, misapplication or evidence of abuse may be cause for rejection of warranty
claims.

Travel time, mileage and shipping charges will not be allowed. Minor adjustments of heaters are dealers’
responsibility. Defective parts must be tagged and held for possible return to the factory for 60 days from

DESIGN RELATED SAFETY FEATURES

1) FLAME FAILURE

The electronic ignition control shuts off the gas supply in .8 seconds if flame is lost to prevent
raw gas from leaving the heater.

2) OVERHEATING

The totally enclosed motor is protected by thermal overload. A manual reset high temperature
limit switch is mounted in the heated air stream.

3) LOW SUPPLY VOLTAGE

A panel mounted voltmeter indicates supply voltage before heater start up and also during
heater operation.

4) BLOCKED AIR SUPPLY

An airflow switch detects the differential pressure in the combustion chamber and shuts off
the gas flow when airflow is insufficient.

5) LOCKING GAS SELECTOR LEVER

To avoid over firing of the heater and damage to property, make sure the lever is locked in
position when using propane.

6) LOW SHELL TEMPERATURE

The Model 1800(SL) is designed with a burner heat shield to keep the outside shell cool for
added safety in the work place.

7) DURABLE CONSTRUCTION

The Model 1800(SL) uses a heavy gauge steel housing and a stainless steel burner for long life
and consistent performance.

NOTE: In order to maintain the highly efficient combustion of the heater, the combustion cham­ber must remain as manufactured. Any change or distortion could alter the fuel/air mixture and
create excessive products of combustion.

INSTALLATION

The Heat Wagon Model 1800(SL) is a direct fired gas heater intended to be used primarily for the
temporary heating of building under construction, alteration, or repair. Since all the products of
combustion are released into the area being heated, it is imperative that adequate ventilation is pro­vided. The flow of supply air and combustion gases must not be obstructed in any way.

1. The heater is designed for indoor or outdoor installation in a horizontal position. Allow the
following clearances from any combustible material or fuel containers.

Front Outlet: 10 feet Sides: 2 feet
Intake: 1.5 feet Top: 4 feet

Also make sure that no flammable vapors are present in the space where the heaters is being used.

2. The heater should be inspected before each use, and at least annually by a qualified service
person.

3. The hose assembly must be inspected prior to each use of the heater. If it is evident that there is
excessive abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put
into operation. The replacement hose assembly shall be that specified by the manufacturer.
See parts list.

4. When connecting the heater to a natural gas or propane supply line ensure that the pressure at
the heater inlet is within the specified range. Excessive pressure (over 50 psig) will damage the
controls and void the warranty.

5. Connect the hose assembly to the heater gas inlet elbow. The 1800 elbow has 3/4” Female NPT
thread, 1800SL elbow has a 1/4” Female NPT thread. The hose assembly is supplied with a
swivel connector to avoid kinking or twisting the hose. Use a minimum inside diameter of 1/2”
on LP or 3/4” on natural gas installations. Ensure that the hose assembly is protected from
traffic, building materials, and contact with hot surfaces.

6. After installation, check hose assembly for gas leaks by applying a soap and water solution to
each connection.

7. Connect the heater to an adequate 115 volt electrical supply as specified on the rating plate. For
protection against shock hazard the supply cord should be plugged directly into a properly
grounded three-prong receptacle.

EXTENSION CORDS:

Properly Wired and Grounded
Use #14 wire up to 100’
Use #12 wire up to 200’
Use #10 wire up to 300’

8. Replacement parts are available from any Heat Wagon distributor or by calling 1-888-432-8924
for parts information.

MODEL 1800 & 1800SL

PROPER SET UP:

Model 1800SL is a liquid withdrawal unit. This unit
will use 8.25 gal of LP per hour. Use at least (1) 200
gal. withdrawal tank. This will insure 20 hours of
continuous operation. Since the 1800(L) is a Liquid
Propane unit, it must be set up outside of the build­ing. Use 3/8” or 1/2” LPG approved hose or copper
tube.

Model 1800S is a Vapor Propane or Natural Gas unit.
When using Propane (liquid or vapor) turn the fuel selec­tor valve (located on the lower manifold) to the Propane
position. When using Natural Gas turn the selector valve
to the Natural Gas position. This unit can be set up
indoors or out.
