Condensate from the boiler is slightly acidic with a pH of 3.2 - 4.5. To avoid long term damage to the drainage system and to meet local code requirements, HTP recommends neutralizing condensate with a Condensate Neutralizer Kit (Part # 7450P- 212 for 80/110/150/220/299/301 models, Part # 7350P-611 for the 399 model).

It is very important that the condensate piping be no smaller than ¾”. To prevent sagging and maintain pitch, condensate piping should be supported with pipe supports, and pitched ¼” per foot to allow for proper drainage. Failure to maintain proper pipe size and pitch could result in condensate leakage and potential water damage to property.
