1. Valve Application
These valves are only used to isolate a boiler from the system during low load conditions. A separate
service valve MUST be installed for each boiler. See Figure 1 and Figure 2, which show typical
installation diagrams – local codes and authorities should be consulted for compliance. The primary
purpose of these diagrams is to illustrate the motorized valve location – see specific piping diagram
provided with the AERCO boiler for the rest of the piping details.
These valves do NOT qualify as service valves.
2. Valve Installation Location
a. Benchmark Boilers: Do NOT install the Motorized Control Valve directly against the outlet of the
boiler. The actuator will interfere with venting and boiler sheet metal.
b. Provide ample clearance from venting, water piping, gas piping, electrical, controls, and other system
components. The valve should be installed with a reasonable amount of “working space” around it to
allow room to be able to service the valve and use the manual lever.

3. Valve Orientation
The valve can be oriented in any position as long as the actuator does not go below the horizontal plane.
See orientation guide from Belimo that is attached to the valve.
4. Valve Wiring
See Table 1 on the next page to determine which of the included diagrams to use.
IMPORTANT NOTE!
The valves are supplied with 3 feet of power cable (exception:
Valve PN 92084-7 is supplied with Screw Terminal for electrical
connection) and 3 feet of auxiliary switch cable. If the cables are
not long enough, we recommend that a distribution box be
connected. The power and auxiliary cables are permanently
connected to the valve and cannot be removed.

How to use the below chart:
1. From the first column, identify the AERCO Boiler Series to which the Belimo valve will be
applied. If the Belimo valve is being installed on a BMK boiler that is already in the field, to
determine if the boiler is equipped with BMK Pump Relay Option 69102, see Figure 1 on
next page.
2. From the second column, identify the AERCO part number of the Belimo valve being used.
3. From the third column, identify which AERCO Boiler Valve Controller is being used in the
application.
4. Use the resulting wiring diagram from the last column.
