Operation Manual - 1 piece
3. DESIGN AND OPERATING PRINCIPLE
Heat exchanger is a leaktight flat tank of a rectangular shape with a volume
of 1.8 l.
It is installed on one of the heater firebox walls in order to accumulate
the heat via transferring heat energy from the firebox wall to a closed water
loop.
It is recommended to use with a suspended oval tank.
You will need to remove 3-4 lamellae (Fig.2) to mount the heat exchanger
onto the heater.
To fix the heat exchanger at the place of installation, it is necessary to put
stones into the outer stone heater, while pressing the heat exchanger tightly
to the surface of the inner stone heater.
