o
C.
4. Ensure the correct pressure relief valve has been supplied. 60 PSI (415 kPa) pressure relief valve
is suitable for low pressure mechanical heating or process heating applications only on ‘H’ model
water heaters. 150 PSI (1000 kPa) pressure relief valve is suitable for mains pressure DHW
application
on ‘W’ model water heaters and ‘H’ models being used in high temperature DHW
applications.
