Hot water temperature thermometer
OPERATING PRINCIPLE/TECHNICAL DATA
The boiler-stove is designed to heat the room it is installed in by convection, radia-
tion and the water found in it, which is sent to heat radiators and/or to the domestic
hot water system (according to the type of system). The heat is generated by burning
wood in the thick steel firebox.
The smoke leaves through the flue with natural draught.
Ash falls into the pan where it gathers for emptying.
Optimum performance is also obtained thanks to the following features:
PRIMARY AIR REGULATION (for combustion)
Combustion air intake is automatically regulated by the control valve found on the
back of the boiler-stove according to:
- the position of the knob
- the water temperature
AUTOMATIC SMOKE BY-PASS VALVE
During the ignition stage with the door open, the smoke shutter stays in an open
position so that the smoke can reach the flue directly and easily to help combu-
stion begin.
When combustion is well under way, closing the door also automatically closes
the smoke shutter.
In this situation, the smoke is diverted before reaching the flue so that it flows
against and transfers heat to the hollow jackets and heat exchanger tubes.
SECONDARY AIR REGULATION
The fixed secondary air flow goes directly to the firebox through the slits in the
upper part of the firebox door. As well as allowing the ceramic glass to clean itself,
it helps burn any gases which may be given off by incomplete wood combustion,
thus reducing dangerous gas emissions into the environment.
AUTOMATIC DOOR CLOSURE
The firebox door (made of cast iron with high temperature resistant ceramic glass)
allows a panoramic view of the fire and closes automatically with a spring return
for optimum combustion.
