Stack Damper
Introduction
In some applications, a stack damper is used to prevent a draft from coming into the boiler
when the boiler is shut down. However, the stack damper needs to be open during boiler
operation. Typically, it is desired to have the stack damper fully open before the combustion
fan turns on, and to leave the damper open until the combustion fan turns off again. The
following procedure will describe how to wire a stack damper to the LMV3 so that the damper
is open anytime the combustion fan is on.
Procedure
2. Wire the LMV3, RWF5x load controller, and stack damper as shown in Figure 13.
