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
