** NOTE: The reason the Riello burner nozzle sizes are smaller than the standard Thermo Pride burner nozzles is
that pre-set pump pressures are higher, therefore achieving the same firing rate with a smaller nozzle.

I. HEAT EXCHANGER CLEANING INSTRUCTIONS:
? ? ? ? WARNING: THE HEAT EXCHANGER MUST BE CLEANED BY A QUALIFIED
SERVICE PERSON.
It is important to inspect and clean the heat exchanger once a year, or as necessary, to remove any build-up of soot.
A layer of soot on the inside of the heat exchanger will act as an insulator and reduce heat transfer, resulting in less
efficiency.
To clean the heat exchanger, first turn off all power to the unit. Next, remove the access panel (see below and
beginning of following page) immediately above the burner (on the horizontal furnace, it will be located to the side
of the burner) to gain entry to the clean-out covers, refer to figure 15. This panel is identified with a label. Remove
clean-out covers, the vent connector pipe to the chimney, the burner, and the burner mounting plates. When
removing the clean-out covers, special care must be taken not to damage the gaskets. Should the gaskets separate,
crack, break, or be unsuitable for reuse, the gasket must be replaced before reattaching the clean-out covers.
