A variety of matching valves and other accessories are available and recommended from MYSON. For
specific applications see our detailed installation and technicals manuals and price book which are
available on our web site.
It is assumed that the installer has the appropriate technical knowledge related to building codes,
standard trade practices, and proper use of the tools of the trade.
Myson radiators should only be used with recirculation pump closed loop hydronic heating systems such as 2 pipe
reverse return, 2 pipe direct return, 1 pipe monoflo or homerun piping systems. Series loop piping is not
recommended. Myson radiators are not for use in gravity or steam systems. 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 suggested location for your Myson radiator, where possible, is below a window
where it can minimize downdrafts from glazed areas. Mounting the radiator a minimum of 4 inches off the floor

Myson radiators are supplied with drain plugs, vent plugs, and mounting brackets.
Failure to flush system of debris and flux may cause premature radiator failure, which can result in leaks and
property damage NOT covered under the Myson Warranty.
Step 1 Fill and vent the system.
Step 2 Run the system for two (2) hours at full temperature with all radiator valves in the open position.
Step 3 Shut off and drain the system while the water is still hot.
Step 4 Refill the system.
Step 5
Reheat, vent, and balance the system.
Step 6 Once the Décor Radiator is filled with water the system should be left filled.
Step 7 System should be checked for leaks on seasonal start-ups. Leaks must be repaired
as automatic system fill valves allow fresh water/oxygen into the system attacking
radiators internally.
SYSTEM START-UP
MAINTENANCE &
CLEANING
1 Once operating, avoid the introduction of fresh water and oxygen to the system to prevent corrosion.
2 An occasional wiping with a damp cloth using a non-abrasive detergent can protect the finish of your
Myson radiator.
3 The use of abrasive cleaners will damage the surface of your radiator and void the manufacturer’s warranty.
DESIGN AND LAYOUT CONSIDERATIONS:
NOTE! For optimum performance connect the supply to the top and the return to the bottom of the opposite side. Bottom
supply and return will result in a 5% reduced heat output. (See online manual for detailed piping diagrams.)
VALVE ROUGH-IN: When using Myson radiator valves to install your radiator add the following distance from
the end of the radiator to the center of your Supply/Return pipe for each valve.
For 2TRV1/2AN a
nd LKD16AN valves add 1-3/4" ---
For 2TRV1/2IN and FF16LAC/FF16WAC valves add 1-5/8"
MOUNTING: Myson horizon
tal radiators 3H to 11H are supplied with welded mounting lugs located 6-15/16" in
from each end. Myson vertical radiators V11 are supplied with welded mounting lugs located 4-1/4" in from
each end (top and bottom). Pedestal style radiators H34 are supplied with adjustable height stands. Myson
baseboard style radiators 2H are supplied with the appropriate number of brackets for each length. (See
Mounting Detail Supplement for more information)
For more detailed bracket installation dimensions and mounting positions please consult the
detailed installation manual available at MysonComfort.com and/or the assembly instructions
included with the mounting brackets.
SAFETY PRECAUTIONS
Radiators are hot when in use, and as such, present a risk of burns to users on prolonged contact. The
temperature of a
radiator is dependent on the temperature of the system water, as set by the system installer
or user. Installers and users should take all necessary steps to minimize the risks of burns. If the risk is
significant, consideration should be given to installing low surface temperature radiators, or to placing guards in
front of the radiators.
For
the correct installation of radiators it is essential that the mounting of the radiator to the wall is carried out
in such a way that it is suitable
for intended use AND predictable misuse.
VENT LOCATION: The radiator vent should be located on the return side of the radiator at the top tapping.
