Connection of the condensate drain piping system

is to the back of the unit beneath the flue/combus-

tion air separator tube assembly. The condensate

drain tube provided in the un it is 1 - 19/3 2 inche s (40

mm) O.D. to which the drain trap assembly supplied

with the unit may be connected. The condensate

drain outlet connection on the trap is 1 - 19/32 in-

ches (40mm) O.D. to which standard 1 -1/2 inch tra-

de size schedule 40 PVC pipe can be connected to

create the rest of the drain system. The drain sys-

tem must pitch downward towards the sewer.

Note: The condensate will not likely require any spe-

cific water treatment because of condensate dilution

by normal wastewater use. If, however, local regula-

tions require wastewater to have a neutral pH, a

condensate treatment tank can be installed

between the trap and the sewer.
