Mk8 MM Manual Page | 68
3.2 Installation Checks
3.2.1 Commissioning Checks
When all the installation and burner adjustments are completed, the entire burner control system should be
tested in accordance with the manufacturer’s instructions. The procedure should verify the correct operation
of:
1. Each operating control (temperature, pressure etc.)
2. Each limit switch (temperature, pressure, low water cut-off, etc.)
3. Each interlock switch (airflow switch, high and low fuel pressure or temperature switches, purge and
low fire switches, fuel valve proof of closure interlock etc.)
4. Pilot flame failure response and lockout.
5. Main flame failure response and lockout.
6. Tight shut-off for all valves.
3.2.2 Operational Checks
1. Close manual main shut-off valve.
2. Check all limit circuit wiring for proper operation and correct connection.
3. Confirm that the automatic main fuel valves are wired correctly.
4. Power the control and electronically check the proper sequence of operation.
5. After assuring yourself that all the interlocks and valves are properly wired and that the sequence of
operation is correct, open the manual main shut-off fuel valve and proceed cautiously through the
boiler light off process. Check all safety interlocks for proper shutdown of the boiler.
3.2.3 Installation Precautions
The reliability of the equipment may be impaired if used in environments where strong electromagnetic fields
exist e.g. if the equipment is installed in a boiler house where radio systems exist then additional EMC
(Electro Magnetic Compatibility) measures may have to be considered. Please contact Autoflame for more
information.
3.2.4 Maintenance and Servicing
The Micro-Modulation unit uses solid state technology. It requires no routine maintenance.
The servomotors/gas/oil/FGR valves do require routine maintenance. Any fault associated with these parts is
usually diagnosed by the MM. Contact Autoflame for preventative maintenance procedures, please refer to
the Valves and Servomotors manual for general checks.
