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.

DESIGN RELATED ADDITIONAL 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 S1505 used 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.

INSTALLATION

The Sure Flame Model S1505 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: 20 feet Sides: 2 feet
Intake: 2 feet Top: 4 feet

Front outlet must not be directed at any LP-Gas container within 20 feet.
Also make sure that no flammable vapors are present in the space where the heater is being used.

2. When connecting the heater to a natural gas or propane supply line ensure that the pressure at
the heater inlet is within specified range. Please refer to Propane and Natural Gas installation
sections on Page 7. Excessive pressure (over 1/2” psig) will damage the controls and void the
warranty.

3. Visually inspect the hose assembly and ensure that it is protected from traffic, building materials,
and contact with hot surfaces. If it is evident that there is excessive abrasion or wear, or the hose
is cut, it must be replaced.

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

5. Connect the heater to an adequate 115 volt electrical supply and in compliance with the
National Electrical Code ANSI/NFPA 7.0. 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’

6. In all applications install the heater in such manner it is not directly exposed to water spray, rain
and or dripping water.
