Condensate Drain
Check with your municipality, or local gas company, to determine if the disposal of
combustion condensate is permitted in your area (e.g. in the State of Massachusetts the
condensate must be neutralized prior to entering a drain).
The following are important notes that must be taken into consideration when constructing the condensate drain
system (See Condensate Drain section of the boiler Installation Manual for further details):

DO NOT install condensate lines outside. A frozen or blocked drain will cause the condensate to back-
up and leak. This may result in damage to boiler components resulting in a no heat condition; property
damage may also occur.

NEVER use copper, steel, or galvanized piping in the construction of the condensate system
(condensate is very corrosive and will corrode most metals).

When a condensate pump is used or required, select a pump that is designed for residential furnaces.
13. Siphon – Install the Siphon to the fitting of the Horizontal Drain. Connect a field supplied
condensate hose and route to an appropriate drain.
