8. Remove the pin located to the left of the door, that locks the hinge in place. Once the pin is
removed, the door will be free to rotate about the hinge, providing better access to the inside of
the heat exchanger.
BE CAREFUL NOT TO DAMAGE THE EQUIPMENT OR THE BURNER,
WHICH ARE MOUNTED TO THE DOOR, WHEN ROTATING ON THE HINGE.
9. Swing open the burner door/heat exchanger door to provide access to the inside of the heat
exchanger. The burner does not need to be removed. Patterson-Kelley does not recommend
removing the burner, though it may be removed to provide better access for cleaning the
exchanger.
10. With the coils to the heat exchanger now accessible, clean the coils with a non-steel brush
(
preferably nylon). Vacuum out any large debris that is “knocked loose”.
ANY CLEANING OF
THE COILS WITH ACID OR ALKALI PRODUCTS IS PROHIBITED.
However, Patterson-
Kelley recommends using a white vinegar solution to assist with the cleaning of the coils.
BE
SURE NOT TO GET EITHER THE DOOR REFRACTORY, OR THE INNER EXCHANGER
REFRACTORY, WET.
11. Once the coils have been cleaned, rinse the coils with clean water.
BE SURE NOT TO GET
EITHER THE DOOR REFRACTORY, OR THE INNER EXCHANGER REFRACTORY, WET.
12.
Use a pressurized water hose with control nozzle. Begin by spraying just a few seconds of
water into the combustion chamber and then close off the nozzle.
13.
Walk around to the rear of the boiler and ensure the wash water is draining into the temporary
drain hose off the condensate drain. Adjust the temporary drain hose if needed to help drain the
wash water from the boiler.
