building.
Too high consumption
of fuel
1. Incorrectly installed central heating
system.
2. Incorrect selection of the boiler in
relation to the building.
3.
Fuel of low calorific value.
4.
Improper parameters of boiler
operation.
1. Check the central heating
system.
2. Carry out a short energy audit
3. Replace the fuel with the
appropriate fuel.
4. Set proper parameters for
boiler operation.
Flame image
1. red
2. blue
3.with noise
4.small flame
1. Lack of secondary air.
2. High secondary air supply.
3. High primary air supply.
4. Lack of primary air.
1. Increase the supply of
secondary air.
2. Decrease the supply of
secondary air.
3. Decrease the supply of
primary air.
4. Increase the supply of primary
air.
The chimney smokes
1.
Low secondary air supply
2. If it still smokes...
1. Completely open of
secondary air opening
2.
…completely open of
secondary air opening and
reduce the primary air supply.
Condensation inside
the boiler
1. Condensation of air and exhaust gases
during ignition of the boiler
2.
Very low return temperature
3.
F
uel with very high amount of moisture
4. Low chimney draft
5.
Small section of chimney
6.
Faulty connection to the chimney
7.
Concentrates or rain entering the
chimney
1.
During ignited adjust the
boiler temperature above 70
o
C
and keep it for a few hours
2. The boiler must be protected
from low return temperature with
a three-way valve. The minimum
return temperature is 50
o
C.
3.
Use dry fuel with
moisture<20%
4.
Check the chimney and clean
it if it is necessary
5.
Check the sizing of the
chimney in accordance with the
instructions
6.
Ensure tight connection of the
boiler to the chimney
7.
Check the installation of the
chimney and place protective
hat if it is necessary
The fan does not start
1. Fan failure
2. Burned out fan
1. Check electrical connection of
the fan.
Check the capacitor of the fan
engine.
2. Replace the fan with a new
one.
Poor combustion
1. The fan feeds too little air
2. Too little chimney draught
3. Incorrect air supply system
1. Clean the fan, adjust the
quantity of air with the adjusting
screw.
2. Measure the chimney
draught.
Install a draught generator.
3. Check the patency of the air
supply duct.
