Do not use solvents to clean any of the burner
components. The components could be dam-
aged, resulting in unreliable or unsafe operation.
Check System Piping
1. Inspect all piping (water and gas) on the boiler
system for leaks and verify that the piping is
leak free and properly supported.
2. Inspect the fittings and components on the unit
and verify they are leak free.
Eliminate all boiler water system leaks.
Continual fresh make-up water will reduce the
heat exchanger life causing boiler failure.
Leaking water may also cause severe property
damage to the surrounding area. Inspect the gas
supply piping for any leaks.
Clean Condensate Drain Assembly
1. Loosen the retaining nut from the condensate
drain assembly and disconnect the assembly
from the boiler.
Ensure the installation of the condensate drain
assembly included the metal washer when
attaching to a polypropylene condensate pan.
Failure to comply could result in the trap assem-
bly dislocating from the boiler.
2. A new metal washer must be installed if the
installation of the condensate drain assembly
did not include a metal washer when attaching
to a polypropylene condensate pan. The new
metal washer must first be cut using a pair of
diagonal cutting pliers to make it into a split
washer. Insert the split metal washer into the
retaining nut and screw onto the condensate
drain assembly without rubber gaskets. Use the
condensate drain assembly as a tool to press the
retaining nut with split metal washer onto the
polypropylene condensate pan. Unscrew the
condensate drain assembly and proceed to the
next step.
3. Empty any water from the condensate drain
assembly. Flush with fresh water as necessary
to clean.
4. Check the drain piping from the condensate
drain assembly to the drain. Flush to clean as
necessary.
5. Reassemble the condensate drain assembly onto
the boiler by tightening the retaining nut with
rubber seal onto the boiler.
6. Remove the fill plug on the condensate drain
assembly and fill with water.
7. Replace the fill plug on drain assembly.
