-Condensate Drain Connections-
The water heater is a high efficiency condensing model that produces condensate (acidic water) The
acidic condensate generated in the secondary heat exchanger can be neutralized by the Neutralizer acces-
sory
Case A: If a neutralizer is not required
1 Connect a 1/2” FPT X 3/8” (or 1/2”) HB Adaptor to the condensate drain port at the bottom of the
water heater
2 Connect a condensate drain tube to the 1/2” FPT X 3/8” (or 1/2”) HB Adaptor The manufacturer
recommends the material of the condensate tube be either EPDM or PVC
3 Leave an adequate amount of space between the end of the drain tube and the actual drain, to
facilitate proper drainage
Case B: If a neutralizer is required (installing the Neutralizer assembly)
1 Connect the 1/2” FPT X 3/8” MPT Adaptor to the condensate drain port at the bottom of the water
heater
2 Connect the Neutralizer to the 3/8” MPT connection of the adaptors There is a flow direction indicator
on the neutralizer Please orient the neutralizer in the proper direction
3 Connect a 1/2” drain tube to the other end of neutralizer
4 Leave an adequate amount of space between the end of the drain tube and the actual drain, to
facilitate proper drainage
