Install the thermowell (P/N 49263) into the lower port on tank (see Figure 3-16) with pipe
dope, then put heat conducting compound (P/N 122848) inside the thermowell.
8.
Put the temperature sensor probe through the cord grip (P/N 62005) and then insert the
sensor fully into the thermowell (see Figure 3-16). Screw the cord grip into the thermowell
and then tighten cord grip to secure the temperature sensor probe in the thermowell.

Install pressure relief valve (P/N 92129) into upper port of tank using appropriate pipe dope
(such as Loctite 567). Valve outlet should point downwards (Figure 3-16).
