and initiate the ignition sequence, or Feed Start State.
2.
After burner has been running in the Firing State for approximately 5
minutes, insert the combustion analyzer into the exhaust gases
outlet/chimney and take readings
3.
Adjust the air setting by adjusting the “Fan High Speed” value if
more/less air if needed. Adjust this value by pressing the “Parm”
button until “Fan High Speed” appears on the display and use the
“+” and “-“ keys to adjust the value up or down. The maximum
setting for the Fan High Speed is 255.
Combustion adjustments to feed rate and fan speed can be made while
the burner is running to obtain the proper combustion properties.
Remember to wait least 2-3 min between making changes to the
controller to allow the combustion within the burner to stabilize.
Burner settings and tuning should be accomplished to establish these
operational values:
CO
2
= 10-12%
CO = Less than 300 ppm
Efficiency = Maximized using firing rate
Burner Cycles
The PB-1525 is fully automated and will respond to the heating demand as
called for by a thermostat.
It is important to reduce the total number of operational cycles by as
much as possible to ensure the most efficient operation of the system and
to avoid premature failure of system components. On average, systems
will operate between 10-20 times per day during the heating season.
