3.2 Installation Checks
WARNING
Electrical Shock Hazard, Fire or Explosion Hazard. Can cause severe injury, death or property
damage.
1. Use extreme care while testing the system. Voltage is present on most terminal connections when
power is on.
2. Isolate the power before removing or installing the Autoflame Flame Safeguard Controller.
3. Make sure all manual fuel shutoff valve(s) are closed before starting the initial lightoff check and the
Pilot Turndown tests.
4. Do not put the system in service until you have satisfactorily completed all applicable tests as
required by regulations and the equipment manufacturer.
3.2.1
Configuration Checks
When all the installation and burner adjustments are completed, the entire burner control system including the
Flame Safeguard 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 gas/oil 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.
