42/50

 

 

In case that this quantity is 
higher than required, than 
decrease the thermal 
capacity of the unit or 
increase the air flow rate 
by repositioning the 
control flap of the air fan; 

15.

 

High 
temperature of 
the flue gases (if 
flue gas 
thermometer is 
mounted) 

The heat exchanging 
surfaces of the heat 
consumer are 
deposited with ash, 
presenting heat 
resistive layer, thus 
decreasing the heat 
exchanging intensity 

It is necessary to clean thoroughly 
the heat consumer surfaces in 
order to decrease ash layer heat 
resistance; 

16.

 

Flue gases are 
emitted out of 
the heat 
consumer unit 
after certain 
period of 
exploitation 

The flue gas duct is
clogged or even
blocked by fly ash
deposits 

It is necessary to clean thoroughly
the heat consumer’s flue gas duct 
as well as chimney

;

 

17.

 

Other failures, 
not described 
above 

 

It is necessary to consult 
authorized technician and 
eventually service maintenance 
should be performed
