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.

￿WARNING The recommended maximum high temperature to the valve should be 175°F; the

absolute maximum is 195°F.
