Connect the hot water supply line to the Hot Water Outlet.
Ensure there are no kinks or sharp bends that might restrict
the fluid flow. If bends are required for PEX tubing, fit the
tubing into a plastic bend support. Do not use rubber heater
hose for potable water plumbing. See Figure 7-2: The
Approved Method of Installing Heater Hose (Consult ITR for
Alternative Methods and Products) for methods of attaching
heater hose.

A drain point, labeled “Drain” is provided on the front lower
middle face of The WaterHeater™ by ITR and consists of a 1/2”
threaded pipe with a temporary plastic cap installed. Prior to
filling The WaterHeater™ by ITR with water, remove the plastic
cap and install the drain valve (provided) and tighten to a leak
free condition. Use two wrenches. Use a food safe Teflon tape
for thread sealant. If the Space Heating Module has been
added, see the Space Heating Module instructions before
installing the drain valve.

A suggested procedure for filling The WaterHeater™ by ITR is
to close The WaterHeater™ by ITR drain valve, open the
highest hot water faucet in the domestic water system, open
the valve to the cold water inlet to The WaterHeater™ by ITR
and then allow to fill. Once the water is flowing in a steady
stream from the hot water faucet, close the faucet.
