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 com-
bustion chamber must remain as manufactured. Any change or distortion could alter the
fuel/air mixture and create unwanted gases.
