Manufacturer Recommendation
A water sediment filter for potable water before entering the boiler is highly recommended to
prevent errors and lockouts. The filter prevents any sediment and debris from your water supply
piping from entering the boiler. Debris carried from the water supply will clog DHW water flow
sensor resulting in error codes and causing boiler to lockout.
Locate the filter as close to the boiler as possible and place on DHW (domestic hot water) inlet
connection located at bottom of the boiler.
