Myson products are designed to be installed by professional trades people. Myson instructions
are meant to be thorough; however 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. Should a homeowner without such knowledge or skill take it upon him/herself to attempt the
installation, Myson will not be responsible for any damages, injuries or unsatisfactory performance
of the Myson product used.
NOTE:
MYSON products have
BSP
male and female threads. BSP threads are a
straight running
thread NOT tapered like NPT
. Myson Radiator Valves are designed with BSP threads at radiator
side and NPT or compression connections to system piping.
Step 1
Clean all threaded surfaces (both external and internal).
Step 2
Apply teflon tape or pipe dope to the male threads, leaving the first thread exposed. If using
pipe dope, also apply to the female threads of the radiator. Common practice to seal BSP
threads is to use heavy duty teflon tape, such as is used to seal gas pipe fittings, or anaerobic
pipe dope.
Step 3
Using accepted trade practices assemble and wrench tighten fittings until proper
alignment is obtained.
