a) cooling water discharge branch (G ¾)*
b) temperature sensor screwing socket (G ½)
c) cooling water supply branch (G ¾)*
* a and c connections can be inter-changed
The temperature valve is connected to the cooling coil
(
see recommended boiler house connection layouts
).
Temperature valve has to be connected with no less than ¾
inch pipes, temperature sensor of the valve is inserted into
socket „
b
“ (
see fig. 5
).
The temperature valve used shall have the following
parameters:
Min water temperature
10 ºC;
Opening temperature
95 ºC;
Max water temperature
110 ºC;
Max water debit
6,5 m³/h;
Max water pressure
10 bar.
If the electric power supply is interrupted in the house with the local water supply
system (water is supplied by hydrophore) boiler overheat can occur (stopped heating
system circulation pumps) it is necessary to have the extra water supply to the cooling
system.
Attention ! Emergency cooling coil cannot be used for hot water preparation.

Boiler operate
Boiler can be operated by adult persons well familiarized with boiler construction
and this technical certificate.
The recommended fuel moisture should not exceed 25 %.
Attention! When boiler is fired with damp fuel (firewood or chips), formed condensate
combines with combustible gases resulting in acids, which reduce service life of
the boiler significantly. Besides that, this is inefficient, because given efficiency
rate cannot be reached, so much more firewood is consumed.
If damp fuel is used for stoking, the specified efficiency factor cannot be reached,
so much more firewood is needed.
Notice. User is allowed at its discretion to use other solid fuel, but requirements of
chapter 6.1 should be not violated and with meaningless claims to the
manufacturer on the output.
Notice. If in the room, where the boiler is operated, there are more air using
equipment, than the sufficient fresh air intake into the room must be ensured for
all equipment.
