Performance capability of the safety valve is checked by shaking if the valve is functional, you will
hear a distinctive sound of valve jingling in both ways which indicates that nothing blocks its
movement.
On the front wall of the furnace there is a heat-control shutter (point 10) which allows the
furnace to operate in two modes: “intensive heating up of the sweating room” and “intensive heating
up of the heater”
The boiler grate (point 11) is installed at the bottom of the furnace. Through the slots in the
grate the air comes to the heater which is essential for high-temperature combustion process.
Combustion products also get to the ash box (point 15) through the boiler grate.
At the top of the furnace there is a flue-gases outlet (point 12), a steam pipe (point 7), a pipe
of a steam generating unit to connect it to the dispensing unit, and a cleanout port (point 16).
The cleanout port serves to clean and examine manufacturing clearances between the
heater and the furnace body. Examine manufacturing clearances not less than once a year or when
there is a di culty of a chimney draft. In case if there is a lot of soot in the clearances, clear it o with a
flexible brush for smoke pipes (pic.1). In order to get to cleanout port, ease o the cap nut on the lid of
the cleanout port with a 13 mm wrench. While lifting the nut up, make three full rotations (don't
unscrew the nut completely) then move the lid of the cleanout port aside and take it out of the port.
Put the lid of the cleanout port back after the examination and tighten the cap nut.
The front of a furnace consists of a specially shaped frame with a door (point 14) and air
governor (point 17) attached to it.
The front of a furnace and its body are separated by the fuel channel (point 13) which allows
lighting the furnace from a room adjacent to the sweating one.
The furnace is painted with black organosilicone enamel.
