Setting the Cleanout Cycles
As an option, the PB-1525 can be fitted with an automatic burn chamber
cleanout system that will serve to keep the burn chamber cleaner and
more clear of clinkers during extended periods of operation. The system
utilizes a set of air nozzles affixed to the inside of the burner connected to
an air line, compressor and solenoid valve; all provided by Pellergy. The
burner controller will activate the solenoid valve at a set time during the
Purge cycle to push the by-products of combustion into the ash collection
area of the boiler.
The frequency of this cleanout cycle is set within the controller and can
be set to blow down the burn chamber every cycle or every “N” cycles as
set by the Certified Installer. To set the number of cycles between
cleanout system activation, follow the steps below:
The system must be in Technician Mode.
1.)
Press the “Parm” button until “Cleanout Cycles” is displayed on the
controller.
2.)
Use the “+” and “-“ buttons to add or subtract cycles.
The set number is the number of cycles the controller will wait to perform
the cleanout function. Pellergy recommends starting with a value of 10
and adjusting from there depending on the feedback regarding pellet
quality.
Installation and Setup of the Flue Gas Temperature Sensor
The PB-1525 requires the installation of a supplied flue gas sensor in the
stack of the boiler/furnace. This sensor should be installed as close to the
boiler/furnace flue collar connection as possible without causing damage
to the leads of the sensor.
The sensor is installed using a 0.25” hole in the smoke pipe and two self
tapping sheet metal screws.
The Pellergy PB-1525 controller will constantly monitor the stack gas
