TIPS FROM TECHNICAL SERVICE
Flue Gas Condensation Within Boilers
The following note can be found on the cover page of any of the Slant/Fin boiler
Installation/Operation manuals.
IMPORTANT
RADIANT FLOOR, LOW WATER TEMPERATURE,
And LARGE WATER VOLUME systems require special piping arrangements. See page—.
Additionally, the following will be included in the piping section of the manuals. At a later date,
we plan to add suggested piping arrangements for applications such as these.
RADIANT FLOOR, LOWWATER TEMPERATURE, and
LARGE WATER VOLUME systems: A boiler by-pass loop,
three-way valve arrangement, or primary secondary
pumping (with a boiler loop) must be used to provide
aminimum 130∞Fre,*urn water temperature to the boiler.
This will prevent condensation on the cast-iron sections
that can result in improper cperation of the boiler.
These conditions are detrimental to the proper operation of, and the life expectancy of boilers. They
can cause rust particles to drop to the base of the boiler. It is often the origin of damage to ribbon
type burners used in most boilers. Fortunately, the burners are easily replaced.
These applications can also cause difficulties in Concept 21 and Prodigy 21 boilers. To date, there
have been a several cases of rust particles building up on the ceramic burner surface, causing igni-
tion problems. If a Concept or Prodigy boiler, operating under one of the conditions listed above, and
operated for several seasons, develops unexplained ignition problems, a rust buildup may be respon-
sible. The rust must be removed and the cause of the build up eliminated. If there are any questions
regarding these, or any other operational problems, please contact Tech Service at 1-800-873-4346
Tosum up, systems with RADIANT FLOOR, LOWWATER TEMPERATURE, and LARGE WATER
VOLUME must be carefully piped and configured to avoid low water temperatures returning to
the boiler.
