must be a minimum of ½" clearance between the copper well tube and any
surface within the boiler.
See Electro-Well models on page 8.

LED will not illuminate.
Fuel Smart HydroStat can be installed on an existing immersion well already in the boiler or on a Hydrolevel Electro-Well™
(sold separately). The low water cut-off function is automatically activated when installed on an Electro-Well™.
IMPORTANT: The control will not provide low water cut-off protection when installed on a standard immersion well.
