The Clarke Devil 900DV propane heater is a dual voltage model. This model can be run of an 110 volts or 240 volts input supply and therefore suitable for heating applications where only 110 volts supply voltage can only be used such as building sites. The Clarke 900DV has a heat output 85,000 Btu and weighs only 6.65Kg, hence can be easily moved to where its heat output is required.
Adequate ventilation is required when operating a gas propane space heater. As a general rule of thumb an opening of 1 inch per 1000 Btu/hour is a minimum requirement.
