S1505B Manual 974-9308 Rev. 4.21; Aug 8 2008

InstallationThe Sure Flame Model S1505B is a direct fired gas heater intended to beused primarily for the temporary heating of buildings under construction,alteration, or repair. Since all the products of combustion are released intothe area being heated, it is imperative that adequate ventilation is provided.The flow of supply air and combustion gases must not be obstructed in anyway. Do not use the heater with ductwork as this will restrict the flow of supplyair.

1 Install the heater in a horizontal position at least 6 ft. (1.83 m) from anyLP-gas container, and allow the following clearances from any combus-tible materials:

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 vapours are present in the spacewhere the heater is being used.

2 When connecting the heater to a natural gas or propane supply lineensure that the pressure at the heater inlet is within the specified range.Please refer to Propane and Natural Gas Installation sections in thismanual. Excessive pressure (over 1/2 psig) will damage the controlsand void the warranty.

3 Visually inspect the hose assembly and ensure that it is protected fromtraffic, building materials, and contact with hot surfaces. If it is evidentthat there is excessive abrasion or wear, or the hose is cut, it must bereplaced.

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

5 Connect the heater to an adequate 115 volt electrical supply and incompliance with the National Electrical Code, ANSI/NFPA 70. Forprotection against shock hazard the supply cord should be pluggeddirectly into a properly grounded three-prong receptacle.

6 In all applications install the heater in such a manner that it is not directlyexposed to water, spray, rain and/or dripping water.


Installation Using APropane Supply Cylinder

1 When installing the heater for use with propane gas, set the gas selectorvalve to “Propane” and lock in position.

2 The supply container MUST be equipped with an LP Gas Regulator thatcomplies with ANSI/UL 144 Standard for Pressure Regulating Valves forLP-Gas. Another regulator must be installed in the heater to reduce thepressure from this regulator down to a maximum inlet pressure of 1/2 psi.

3 Arrange the cylinder supply system to provide for vapour withdrawal fromthe operating cylinder. Supplying liquid propane to the heater isdangerous and will damage the components.

4 Ensure that for the surrounding temperature the size and capacity of thepropane supply cylinder is adequate to provide the rated Btu/h input tothe heater.

5 Turn off the propane supply valve at the cylinder when the heater is notin use.

6 The installation must conform with all local codes, or in the absence oflocal codes, with the Standard for the Storage and Handling of LiquediedPetroleum Gases, ANSI/NFPA 58.

7 When the heater is to be stored indoors, the propane cylinder(s) must bedisconnected from the heater and the propane cylinder(s) removed fromthe heater and stored in accordance with the National Standard for theStorage and Handling of Liquedied Petroleum Gases, ANSI/NFPA 58.

Installation ForNatural Gas Applications

1 When installing the heater for use with natural gas, set the GASSELECTOR VALVE to the ”Natural” position.

2 A regulator must be installed on the heater to ensure that the pressureto the heater does not exceed 1/2 psi inlet pressure.

3 The installation of this heater to a natural gas supply must conform withall applicable local codes or, in the absence of local codes, with theNational Fuel Gas Code ANSI Z223.1/NFPA 54.

S1505B Manual 974-9308 Rev. 4.21; Aug 8 2008

Operating Instructions

1. Set GAS SELECTOR VALVE to gas being used. The conversion shallbe done by the owner or lessor of the equipment.Warning: When using propane gas, the GAS SELECTOR VALVE mustbe locked in position.

2. Ensure FIRING VALVE is in the “ON” position.3. Connect power cord to a 115 volt supply.4. Open gas supply.5. Set thermostat to the desired temperature.6. Push START button. After a short delay, the heater will start.

Note: Heater will cycle between high flame, low flame, and off asrequired.

7. To stop: push STOP button. If heater is to remain off, disconnect power,and close gas supply.

The appliance area should be kept clear and free from combustible materi-als, gasoline, and other flammable vapours and liquids.

Ensure that the flow of supply air and combustion gases is not obstructed.

The installation and operation of the heater shall comply with the coderequirements specified by the authorities having jurisdiction.

General criteria for the use of construction heaters may be found in theapplicable sections of American National Standard A10.10-1987, SafetyRequirements for Temporary and Portable Space Heating Devices andEquipment Used in the Construction Industry.

THE INSTALLATION AND MAINTENANCE OF THEHEATER MUST BE ACCOMPLISHED BY A QUALIFIED

SERVICE PERSON.


Common Installation AndOperational Problems

1 LOW VOLTAGEThis is one of the most common problems and is usually the result of thesupply cord having too small of a wire gauge for its length. Low voltageresults in the motor overheating, burnt relay contacts, or a relay that willnot make contact.

2 SUPPLY LINE TOO SMALL3 INSUFFICIENT VAPORIZATION AT SUPPLY

Normally caused by too small size of supply tank.4 IMPROPER GAS SUPPLY PRESSURE

Usually a result of supply pressure being too high because of improperor lack of regulation.

5 DIRTY GAS SUPPLYDirty gas can cause strainers to plug or form a build-up in the burnerorifice.

6 LACK OF PREVENTATIVE MAINTENANCEHeaters must be cleaned as required, especially when used in a dirtyenvironment.

7 IMPROPER SUPPLY OF FRESH AIRIt is normally recommended that the intake air of the heater be taken fromoutside the enclosed area. This provides a slight pressurization andprevents any problems associated with recirculation.

Safety ControlsServicing of Sure Flame Construction Heaters normally involves one ofseveral built-in safety features. The Model S1505B incorporates devices todetect the following:1 LOSS OF FLAME Gas supply is shut off if flame is lost to

prevent raw gas from leaving the heater.2 OVERHEATING (a) Thermal overload protection in the mo-

tor.(b) High temperature limit switch in thecombustion chamber.

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

4 BLOCKED AIR SUPPLY A switch detects the differential pressure inthe combustion chamber and shuts downwhen insufficient .

5 LOW INLET PRESSURE A pressure switch monitors the gas inlet andcloses the safety shut-off valve if pressuredrops below the preset limit.

S1505B Manual 974-9308 Rev. 4.21; Aug 8 2008

Safety Features:1 LOCKING POSITION FOR LPG ON GAS SELECTOR LEVER

Units used with LPG while the gas selector valve is positioned for NaturalGas will produce significantly more heat than the rated Btu/h. This isdefinitely a safety hazard.

2 LOW SKIN TEMPERATURE

Sure Flame Heaters are designed to have a low skin temperature. Thisprovides added safety in the workplace.

3 DURABLE CONSTRUCTION

The Model S1505B uses a stainless steel burner for long life andconsistent performance.

In order to maintain the highly efficient combustion of the Sure FlameHeater, the combustion chamber must remain as manufactured. Anychange or distortion could alter the fuel/air mixture and create hazardousgases.

On-Site Hazards1 SHORTING OUT OF DEFECTIVE COMPONENTS

This is a very common problem which saves short term expense at therisk of a large future cost. Any heaters found in this condition should beremoved immediately.

2 IMPROPER ENCLOSURES

When heaters are installed partially to the outside for fresh air intake,strict adherence must be made to the minimum clearance to combustiblesgiven on the instruction plate. Wood framing around a heater is a hazardand should not be used.

3 SUPPLYING LIQUID PROPANE TO HEATER

This problem has occurred from time to time. To minimize the damage,shut off the gas supply and let the heater run until all of the liquid in thelines has been burnt.


Preventive MaintenanceSure Flame Construction Heaters are built to withstand the rigours ofoperating on construction sites, mining applications, and a multitude of otherlocations where heaters are used. To maintain the reliable performance itis necessary to perform regular maintenance.

A VISUAL CHECKSThe following items should be checked for excessive wear or damage:

1) Wheels2) Cords and Connectors3) Wiring and Conduit4) Heater Shell (including heat shield) and Control Box

B BURNERFlame Rod and Insulator - Clean with soap and water or solvent on a

routine basis. Any build up on burner shouldalso be removed at this time.

Ground Wire - Ensure that the ground wire is secured tothe burner. This is necessary for the flamedetection system to operate.

Spark Plug - Clean with solvent and check spark gap.

C FLAME SAFEGUARD CONTROL

The Fenwall Control can be cleaned using compressed air or alcohol. Donot use any other liquid or aerosol spray cleaners.

In areas of high humidity, the control should be removed and placed ina dry atmosphere when the heater is expected to be out of service for anextended time.

It is recommended that units purchased as spares be rotated periodi-cally, so that each unit will be placed in operation at least once every 90days.

D MOTOR - Motors equipped with oil cups should require only a few dropsof clean, light machine oil every year. Motors not equipped with oil cupsare fitted with sealed bearings and no oiling is required.

E FAN - Check for dust or dirt build up on fan blades. Check the tightnessof the set screw and run the heater to check for fan vibration.
