Assessment

Available plans will be reviewed to assess system design and intent

If specified on hot water system, the contractor will check existing distribution piping layout to ensure that installation of these valves will not result in undesired outcomes, such as unintended flows through other branches/circuits

If specified for one-pipe steam system, contractor will make sure valves will not be enclosed inside a radiator cover

If specified for one-pipe steam system, contractor will ensure that the correct valve type is recommended

Contractor will assess whether the specified valve is the correct type so that the temperature sensor will not be enclosed or trapped behind furniture

Ensure specified valve meets design intent and desired outcome

Isolate TRV location

TRV location will be isolated.

Nearest valves on either side of TRV location will be closed to isolate from the system

Eliminate water/steam supply to valve location
5.3102.32d
Install TRV

TRV will be installed in accordance with manufacturer specifications

In applicable cases, system will be refilled and air will be eliminated

Allow distribution loop to bypass terminal unit/radiator and eliminate over- and under-heated zones
