Relief Valve
Pipe the discharge of the pressure relief valve to prevent scalding in
the event of a discharge, see Figure 10.  e discharge piping must be
sized the same as the pressure relief valve outlet and installed to allow
complete drainage of both the relief valve and the discharge piping.
Figure 10 Relief Valve Piping
Never install any type of valve between the boiler/
water heater and the relief valve or an explosion causing
extensive property damage, severe personal injury or
death may occur!
Flow Switch
 e  ow switch supplied with the boiler/water heater must be wired
to the terminal strip in the control panel to prevent the boiler from
 ring unless there’s adequate water  ow through the unit.  e  ow
switch must be installed in the supply piping adjacent to the boiler
outlet connection.
Failure to properly install the  ow switch may result
in damage to the boiler/water heater heat exchanger
voiding the warranty!
