The Legacy Model LRZ electronic heater has
a standard two (2) inch water header and coupling
design. With this feature, only nominal two inch PVC
or CPVC may be connected to the heater. However,
by installing the appropriate pipe adapters and two
short pieces of two inch plastic pipe (supplied by the
installer), any size existing pipe may be tted to the
heater.
To connect a section of 2” PVC or CPVC pipe
to the heater, rst slip a coupling nut onto the pipe.
Then prepare the end of the pipe with the proper PVC/
CPVC primer and glue. Follow the manufacturer’s
instructions provided with the primer and glue for
preparation procedures and curing times. Apply the
slip-t side of the coupling to the end of the pipe.
Allow the glue to cure completely. Set the o-ring
into the groove on the face of the coupling. Slide the
coupling nut up to the coupling and tighten it to the
threaded connection on the header. See Figure 12.
