Construction
Heater

IMPORTANT INFORMATION! READ FIRST

The heater is designed for use as a construction heater under ANSI Z83.7a-1993. 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.

ARRANTY

All new Heat Wagon and Sure Flame heaters and fans are guaranteed against defective materials and
workmanship for one (1) year from invoice date.

Warranty repairs may be made only by an authorized, trained and certified Heat Wagon dealer. Warranty
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
date of repair. The factory will provide a return goods authorization, (RGA) for defective parts to be
returned.

No warranty will be allowed for parts not purchased from Heat Wagon.

DESIGN RELATED SAFETY FEATURES

1. Locking position for LPG on gas selector lever: Units used with LPG while the gas selector
valve is positioned for Natural Gas will throw significantly more heat than the rated Btu/h.
This is definitely a safety hazard.

2. Low Skin Temperature: Sure Flame Heaters are designed to have a low skin temperature. This
provides added safety in the workplace.

3. Durable Construction: The Model S405 uses a stainless steel burner for long life and
consistent performance.

In order to maintain the highly efficient combustion of the Sure Flame Heater, the combustion
chamber must remain as manufactured. Any change or distortion could alter the fuel/air mixture
and create unwanted gases.

SAFETY FEATURES

Servicing of Sure Flame Construction Heaters normally involves one of several built-in safety
features. The Model S405 incorporates devises to detect the following:

1. LOSS OF FLAME Gas supply is shut off if flame is lost to prevent raw gas from leaving heater

2. OVERHEATING a) Thermal overload protection in the motor
b) High temperature limit switch in the combustion chamber

3. LOSS OF POWER Total shutdown with manual reset required. Any one of the safety devices will
create a loss of power situation

4. BLOCKED AIR SUPPLY A switch detects the differential pressure in the combustion chamber

and shuts down when insufficient
