The LMV36 burner management system is a microprocessor-based burner
control with matching system components for control and supervision of forced
draft burners of medium to high capacity.
For the use of dual fuel application with 2 fuel actuators, the AGM60 dual fuel
switch unit is required.
The LMV36 / AGM60 and this Data Sheet are intended for use by OEMs which
integrate the actuators in their products!
