OUTLET SIDE
Install the water heater. Leave
enough surrounding room for the
radiant heat system equipment.
Position everything so you can
access the equipment during
installation and for future
servicing.
Solder ¾-inch hard copper pipe to
a di-electric fitting threaded on
one end. Solder the pipe to the
unthreaded end. This end will run
from the outlet side of the hot
water heater to the supply side of
the radiant tubing.
Thread the threaded side of the di-
electric fitting onto the hot water
outlet of the hot water heater.
