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 IS NOT designed as an Unvented Gas Fired Room Heater under ANSI-Z21.11.2 and
SHOULD NOT be used in the home.

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.

NFPA-58 1989 STANDARD FOR THE STORAGE AND

HANDLING OF LIQUEFIED PETROLEUM GASES

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.

FOR YOUR SAFETY

DO NOT USE THIS HEATER IN A SPACE WHERE GASOLINE OR OTHER
LIQUIDS HAVING FLAMMABLE VAPORS ARE STORED OR USED.

NEVER USE THE HEATER IN SPACES WHICH ARE NOT SUFFICIENTLY SIZED

INSTALLATION

The Heat Wagon Model 2730C 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 250 psig) will damage the
controls and void the warranty.

5. Connect the hose assembly to the heater gas inlet elbow. The elbow has a 3/4” 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 electrical supply as specified on the rating plate. For
protection against shock hazard the supply cord should be connected directly into a properly
grounded fused disconnect.

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

CLEANING

Heater housing may be cleaned with soap and water.

• Place a plastic plug into the 1” pipe inlet on valve train
