MAINTENANCE PROGRAM

!
Burner and boiler servicing must only be carried out by authorised and qualified personnel at least once a year.
Depending on the type of installation, shorter maintenance intervals may be necessary.
The system operator is advised to take out a maintenance contract to guarantee regular servicing.
WARNING: Use original spare parts.
SAFETY WARNINGS:
1. Turn off the power supply and protect the system from accidental start-up
2. Cut gas supply
3. Make sure there is no residual power in the system and that the actions in points 1
and 2 have been completed.
4. Before opening the burner casing, ensure that the fan motor has stopped completely
Failure to observe any of these instructions will result in the risk of death or injury!
WORKS RECOMMENDED AS PART OF ANNUAL BURNER MAINTENANCE:
• Emergency stop button function check
• Check burner start characteristics
• Run burner test and input measurement in the boiler room
• Clean the combustion components and replace defective parts if necessary
• Check the combustion head components and make sure that all components are in good condition otherwise replace them
• Replace ignition electrodes and nozzle if necessary and check their correct position after any intervention
• Flame monitor and automatic combustion control unit function check
• Clean the fan wheel and the blower and grease rotating parts if necessary
• Perform visual inspection of gas lines in the boiler room and check the gas flow
• Clean the gas filter cartridge with air periodically, replace it if necessary
• After the cleaning of the components of the gas train perform the leakage test
• Make visual inspection of the burner's electrical components and eliminate malfunctions if necessary
• Burner safety devices function check (air pressure/gas pressure switches)
• Commissioning the burner and correct the adjustment values if necessary
NOTES ON REASSEMBLING: Perform the described step in reverse order and make sure to refit components
as they were originally assembled and the system is free from leaks. Use only original spare parts.

EXHAUST GAS LOSS
Exhaust gas loss by way of free heat will
occur as a result of the temperature
difference between the fuel-air mixture
entering the furnace chamber and the
gases discharged. Any increase in the
excess of air and the resultant higher
exhaust gas volume will cause the exhaust
gas loss to rise. The exhaust gas loss can
be calculated as follows:
