H and V models
Suitable for mono-flo, home run or 2-pipe systems
Rough-in
dimension shown at right is for a TRV and a
LKD valve or a pair of LKD valves.
When using FF valves add 3-5/8" to overall length.
Recommendation:
Radiator tappings and valve spuds are 1/2"BSP.
Professional expertise is required when sealing these
"straight" threads. Failure to properly seal the
connections will result in leaks resulting in property
damage.
NOTE ! Myson is not responsible for damage resulting from improper workmanship.
NOTE !
Rough-in information is given for Myson control valves. Valve specifications vary by manufacturer.
Myson will not be responsible for damage or repair of property resulting from the use of non-Myson valves.

•
All installations require 2 valves per radiator
•
All valves are ½” BSP thread for connection to the
radiator and ½” NPT thread for connection to the
system (also includes compression nut and ferrule
for connection to ½” copper)
•
Valves are available in 3 basic patterns: angle,
straight, and inverted angle (TRV only)
•
Basic Installation: use 2 – LKD16AN (angle) or
LKD16SN (straight) manual valves, nickel plated with
screwdriver stops and caps
•
Basic upgrade: use 1
-
FF16WAC and 1 - FF16LAC
manual valves, angle only, chrome plated with white
handles (FF16WAC is adjustable for balancing,
FF16LAC is fixed open but can be closed for service)
•
TRV (thermostatic radiator valves) are available for
automatic temperature control of individual radiators:
available in 3 body patterns, with or without
thermostatic head (sensor), use in conjunction with
LKD or FF

All MYSON COLUMN radiators
are manufactured with an internal
baffle. The tapping with the
baffle is identified with a RED
plastic cap, all others being
BLUE. It is important that the
supply inlet is connected to the
tapping identified in RED.
MYSON COLUMN radiators are suitable for the use of
BBOE (Bottom Bottom Opposite End), TBSE (Top
Bottom Same End) and TBOE (Top Bottom Opposite
End) connections. TTOE (Top Top Opposite End)
connections cannot be used.
All systems must be designed with suitable pipe sizing
and with adequate pump head. Failure to do this
may lead to trapped air and cold spots because of
insufficient pressure and water flow will not drive the
air from the radiator. The taller and more tubes a
radiator has, the more likely this is to happen.
The installation work must be carried out with
precautions taken to avoid contamination which
could lead to corrosion. If a corrosion inhibitor or
other water treatment is to be used, the
Manufacturer’s Instructions must be strictly followed.
The MYSON COLUMN radiator's large diameter
steel tube contruction ensures a negligible
pressure drop through the radiator. The pressure
drop through the radiator can be ignored in the
design of most hydronic systems.
