CHAPTER 9: MAINTENANCE
9.1 Modulex Preventative Maintenance Kits
To perform the necessary maintenance tasks described in this section, AERCO offers a line of
maintenance kits for your Modulex boiler as described below.
9.1.1 Annual Maintenance Kit
Each Annual Maintenance Kit contains a flame detector, spark igniter, and associated gaskets. A
detailed description of the Annual Maintenance tasks can be found in Sub-section 9.2.
9.1.2 Fireside Inspection Kit
Each Fireside Inspection kit contains a flame detector, spark igniter, and gaskets for the flue collector,
burner modules and condensate tray. A detailed description of the Fireside Inspection tasks can be
found in Sub-section 9.3.
NOTE
The Fireside Inspection Kit already includes the components included in
the Annual Maintenance Kit, therefore, when performing the Fireside
Inspection, you only need the Fireside Inspection Kit, not both.
