Condensate Requirements - Munchkin T50M Installing, Operating & Maintaining

VENTING
E. CONDENSATE REQUIREMENTS
This is a condensing high efficiency appliance, therefore this unit has a condensate removal system.
Condensate is nothing more than water vapor, derived from the combustion products, similar to an
automobile when it is initially started. This condensate does have a low PH and should be treated
with a condensate filter. This filter contains either lime crystals or marble crystals, which will
neutralize the condensate. The outlet of the filter is sized for 5/8" ID (Inside diameter) plastic tubing.
It is very important that the condensate line is sloped away from and down to a suitable inside drain,
if the condensate outlet on the Munchkin is lower than the drain, you must use a condensate
removal pump. A condensate filter and a condensate pump kit are available from Heat Transfer
Products, Inc. It is also very important that the condensate line is not exposed to freezing
temperatures, or any other type of blockage. Plastic tubing should be the only material used for the
condensate line. Steel, brass, copper or others will be subject to corrosion and deterioration. A
second vent may be necessary to prevent condensate line vacuum lock if a long horizontal run is
used. Also, an increase to 1" tubing may be necessary.
