Connecting the pressure relief valve (PRV)
A listed pressure relief valve supplied with the heater must
be installed at the time of installation. No valve is to be
placed between the PRV and the heater. No reducing
coupling or other restriction may be installed in the discharge
line. The discharge line must be installed such that it allows
complete drainage of both the PRV and the line. The location
of the PRV must be readily accessible for servicing or
replacement, and be mounted as close to the water heater
as possible. See Fig 7. To install the PRV, a suitable fitting
connected to an extension on a "T" fitting can be sweated
to the hot water line.

Close the hot water faucet after the water flows freely and
all the air has escaped from the system. The water heater
