Water Supply Connections - Bradford White RE2H50R10B-1NCWT Owner's Manual & Installation Instructions

WATeR SUPPLy CONNeCTIONS

Refer to the illustration below for suggested typical installation.
The HOT and COLD water connections are clearly marked
and are ¾" NPT on all models. When connecting to the
inlet/outlet ports, the use of ¾"female NPT tapered thread
fittings with use of thread sealant is recommended. The
installation of unions is recommended on the hot and cold
water connections so that the water heater may be easily
disconnected for servicing if necessary.
NOTe: Install a shut-off valve in the cold water line near the
water heater. This will enable easier service or maintenance
of the unit later.
ImPORTANT: do not apply heat to the HOT or COLd water
connections. If sweat connections are used, sweat tubing
to adapter before fitting the adapter to the cold water
connections on heater. Any heat applied to the hot or cold
water connection will permanently damage the internal
plastic lining in these ports.

CONdeNSATION dRAIN CONNeCTION
This unit has a condensate drain; therefore a floor or other
drain no higher than 36" (91.4cm) above the floor must be
available in close proximity to the water heater. Drain must
meet state and local codes. It is important to install a fitting
suitable for rigid or flexible drain line to the primary drain port
coming off the side of the unit. Ensure that the rigid or flexible
drain line maintains a downward slope to allow for proper
gravity drainage of condensate to the drain. If no drain is
available, then a common condensate pump with a capacity
no less than 1 gallon (3.8L)/day must be purchased and
installed. The rigid or flexible drain line should be routed so
that the discharge water cannot contact live electrical parts or
cause water damage.
