The 'M' means a separate regulator must be used should be upstream of the modulator
The 'R' means the low fire by-pass outlet is on the right side of the valve.
The 'H' means that the valve has the capability for a total modulation span as much as 10" W.C.
Please note that the M420RH is only available in 1/2" NPT (not 3/8")
