Fig. 7 - Pressure Relief Valve
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.
If control button(s) are jammed, close the gas supply and
call a qualified service technician. Attempted forceful repair
may result in a fire or explosion.
