Optional Pressure Relief Valve Escutchen:
Note: If the heater is equipped with an optional Pressure Relief Valve, use
the escutcheon on the Pressure Relief Valve water pipe. If required, before installing the escutcheon, carefully remove
the round Pressure Relief Valve knock out from the heater panel.
The pressure relief water pipe escutcheon ensures the heater is rodent resistant. The following describes how to install
the water pipe escutcheon for a new heater installation. The water pipe escutcheon should be installed when the water
pipe is being installed to the heater.
See page 61 for parts list.
To install the water pipe escutcheon:
1. Place the water pipe escutcheon over the water pipe,
see Figure 47.
2. Slide the escutcheon flush against the heater panel.
4. Hand-tighten the retention screw to secure the escutcheon in place.
