TANKLESS WATER HEATER ISOLATION VALVE KIT INSTALLATION GUIDE

START UP AND NORMAL OPERATION:

1. CAUTION! Before pressurizing the system for
service, make sure that the drain valves on both the
HOT and COLD service valves are put into the fully
CLOSED position. These are closed by turning the
smaller red and blue lever handles clockwise. The
drain valves' lever handles should be positioned
perpendicular to the body of the drain valves. Refer
to photo D. Remove the hose caps and visually
inspect the drain valve outlets to verify that the balls
are in the closed positions. You should be able to see
the chrome plated face of the closed ball assembly.

2. Replace the hose caps and hand tighten only.
3. CAUTION! Before unthreading the hose caps after the valves have been placed in service, make sure
that the drain valves are in the CLOSED position (see step 1). Unthread slowly to allow any possible built-up
pressure to disperse. After removing the cap, inspect the cap gasket for any damage. Replace if necessary.
Both drain valves must remain in the FULLY CLOSED position under normal operating conditions. NEVER rely
on the hose cap gasket to safely keep the primary seal when the valves are in service.
4. Isolation valve handles should be in the FULLY OPEN position under normal operating conditions. Both
red and blue handles should be parallel to the valve body and piping.
5. For water heater start up, please refer to the water heater owners' manual.
DRAIN/FLUSH OPERATION:
CAUTION! Hot water may be present in the system. Use extreme caution when servicing the tankless water
heater. Please refer to the water heater owner's manual for specific use instructions.
1. Disconnect the power supply to the tankless water heater.
2. Close the valve handles on the cold and hot water valves. This will isolate the incoming water to the heater
and the hot water from the piping going to the home.
3. The purge valve on the COLD side will be used as the flushing inlet and the purge valve on the HOT be the
flushing outlet. Ensure that the valve is off before removing the purge valve cap.
4. Slowly open the drain caps, ensuring that the rubber gaskets stay in place.
