APPLICATION
Myson radiators are only for use in recirculating closed loop hydronic heating systems. These
radiators are not recommended for gravity systems. Myson Select Radiators are designed to work
with a maximum working pressure of 78 PSI and no more then 212 degrees F water temperature.
DO NOT USE STEAM IN THESE RADIATORS.
DESIGN AND LAYOUT CONDITIONS
Myson Select Radiators should only be used with a recirculating pump closed loop hydronic
heating system. Please consult national and local codes for specific restrictions that may be
imposed on your installation. Position your radiator away from your circulator pump to avoid
either excess pressure that could force water out the air vent or excess suction that could draw
air into the system. The preferred positioning for the Select radiator is below a window where
it can minimize downdrafts from glazed areas.
Myson Radiators may be hot to the touch. Generally the surface temperature is at 10-12
degrees Fahrenheit below system water temperature. Care must be taken to consider room
occupant’s ability to sense or understand that radiators may be hot. Should radiator surface or
system water temperature be an issue, please contact MYSON at 1-800-698-9690 for information
on the MYSON LST radiators. LST (Low Surface Temperature) Radiators can be a viable solution
where temperatures are a safety concern.

* Using optional EZ-Brackets
It is not recommended to route piping through the walls for single panel radiators (TYPE 11) as
there is generally insufficient room to leave the wall and make the angle into the radiator.
