THEORY OF OPERATION
By opening the supply circuit, the gas arrives to
the pressurised nozzle, where it is nebulised and
mixed to the combustive air in the combustion
chamber. A spark triggers combustion while the
exhaust fumes are expelled from the chimney. A
series of sensors constantly checks the correct
operation of the heater, stopping the cycle in the
case of a fault. The fan, located at the rear of the
heater, cools the combustion chamber and the
flue gas pass, transferring heat from the latter
into the environment.
