Installing Belimo Motorized Valves on AERCO Benchmark Boilers
Technical instruction Document
TID-0028_0C
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.
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.

These valves do NOT qualify as service valves.
