- Fresh Air Blower Interlock
If a Blower is installed to achieve the 40 CPM per 100,000 BTU/hr of Fresh (Combustion) Air Supply
requirement then
an ‘interlock’ connection must be made
between the Blower and Vacuum Switch (and
therefore the Vacuum Pump).
1.
Mount the Vacuum Switch and make the connections to the Blower as required. (See Figure 42 below for
details)
Ensure that field wiring maintains the required clearances when being routed near equipment.
