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
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, LOW WATER TEMPERATURE, and LARGE WATER VOLUME systems: A boiler
a minimum 130∞F re,*urn water temperature to the boiler. This will prevent condensation on the
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
To sum up, systems with RADIANT FLOOR, LOW WATER TEMPERATURE, and LARGE WATER VOLUME must be carefully piped and configured to avoid low water temperatures returning to the boiler.
