Test method Outcome
Step 1
1. Rotate the setting wheel on the switch to its maximum
value.
2. Start the burner.
After testing, return the setting wheel to its original position and
reset the switch.
Boiler pre-purging begins. The burner
must shut down before the pre-purge
cycle is completed.
Error code 2F and the text Gas Pressure
has dropped below minimum Limit
appear on the display.
Step 2
1. Start the burner. Wait until the start-up sequence is
finished.
2. Rotate the setting wheel on the switch towards the
maximum value while the burner is running.
After testing, return the setting wheel to its original position and
reset the switch.
The burner should shut down before the
maximum setting.

Test method Outcome
1. Start the burner. Wait until the start-up sequence is
finished.
2. Drive the burner to maximum capacity.
3. Rotate the setting wheel on the switch towards the
minimum value while the burner is running.

Gas shut-off valves
If the burner is equipped with an automatic valve proving system the valves are tested
to be leak free during each start-up sequence.
To prove the valves manually:
1. Install a pressure gauge between the fuel shut-off valves. Refer to the valve
manufacturer’s instructions for the exact location of the measuring port.
2. Start the burner. Wait until the start-up sequence is finished.
3. Rotate the dial on the gas minimum pressure switch towards the maximum value.
Wait for the burner to shut down.
4. After the burner has shut down observe the reading on the pressure gauge for a
few minutes. The indicated pressure must not lower during that time.
Servomotors
During burner start-up the burner control drives the servomotors to maximum position
and during shutdown to 0-position. The burner control supervises the correlation of the
position settings and back coupling.
During burner shutdown, check the air damper and the locking screws of the fuel
adjusting valve. Push air damper plates lightly to make sure they are firmly attached.

/CO trim control (if equipped)
● The system is self-checking during start-up.
● Confirm proper fuel/air ratio with flue gas analysis.
