8.12 STRAINERS
All SmartPlate Water Heater Models utilize Combination Strainers and Ball Valves to prevent
fouling of the Heat Exchanger by trapping foreign material before it enters the Heater. In
addition, SmartPlate provides a Differential Pressure Gauge on the Boiler Water Inlet to aid in
determining when to blow-down the Strainer. If this Gauge becomes inoperable, it should be
replaced using the following procedure.
NOTE
If normal maintenance does not clear the Water Heater flow path,
it will be necessary to remove and manually clean the screens in
the Boiler Water and DHW piping as follows:
a. Remove Strainer end cap and remove screen.
