Maintenance instructions

The LTV valve is maintenance free.  It does not require regular
cleaning or calibration.  In most installations, the 1-1/2" and 2"
valves are hard piped into place and do not afford access.  The
2-1/2" valve has flanged connects which allows removal.

If the valve becomes unable to maintain a consistent inlet water
temperature of 125°F during steady state firing conditions, replace
the valve or the wax element inside the valve.

The recommended maximum high
temperature to the valve should be 175°F; the
absolute maximum is 195°F.
