INSTALLATION The Sure Flame Models S400 & S400T are direct fired gas heaters intended to be used primarily for the temporary heating of buildings under construc- tion, alteration, or repair. Since all the products of combustion are released into the area being heated, it is imperative that adequate ventilation is provided.
INSTALLATION USING A PROPANE SUPPLY TANK When installing the heater for use with propane gas, set the gas selector valve to “Propane” and lock in position. The supply container must be equipped with a UL listed Gas Pressure Regulator. This is essential to reduce the gas pressure to a safe transmittable pressure.
OPERATING INSTRUCTIONS Set GAS SELECTOR VALVE to gas being used. The conversion shall be done by the owner or lessor of the equipment. NOTE: When using Propane Gas the Selector Valve MUST be locked in position. Ensure the FIRING VALVE (Manual Valve nearest the burner) is in the “ON”...
NOTE: S400 HEATERS WITH SERIAL NUMBER 5984 AND GREATER AND S400T HEATER WITH SERIAL NUMBER 11271 AND GREATER WILL HAVE A 3.3 SECOND DELAY BEFORE STARTING. THE INSTALLATION AND MAINTENANCE OF THE HEATER MUST BE ACCOMPLISHED BY A QUALIFIED SERVICE PERSON. SEQUENCE OF OPERATION Push AND HOLD start button for 5 seconds.
INSUFFICIENT VAPORIZATION AT SUPPLY Normally caused by too small size of supply tank. IMPROPER GAS SUPPLY PRESSURE Usually a result of supply pressure being too high because of improper or lack of regulation. DIRTY GAS SUPPLY Dirty gas can cause strainers to plug or form a build-up in the burner orifice.
DESIGN RELATED ADDITIONAL SAFETY FEATURES 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. LOW SKIN TEMPERATURE Sure Flame Heaters are designed to have a low skin temperature.
PREVENTIVE MAINTENANCE Sure Flame Construction Heaters are built to withstand the rigours of operating on construction sites, for mining applications, and a multitude of other locations where heaters are used. To maintain the reliable perform- ance required it is necessary to do a certain amount of regular maintenance. VISUAL CHECKS The following items should be checked for excessive wear or damage: Wheels (if installed)
TROUBLE SHOOTING S400/S400T An AC Voltmeter is required to perform these checks. The control circuit is 24V, the motor power is 115V. Use extreme caution when checking voltage. 1 Push start button and release 2 Control relay should close. If not, check the following: a) Check for 115V between terminals A &...
