IX TANKLESS WATER HEATING PIPING
The tankless heater may be connected as shown in Figure 3. A mixing valve (not supplied) may be used
to reduce the water temperature at kitchen or bathroom taps. High temperature water for a dishwasher
may be obtained by piping as shown.
The nuts that secure the tankless coil flange should be tightened before the boiler is filled with water,
after initial firing and every year during annual maintenance. Deterioration due to coil gasket leaks shall
void warranty.
* Venting - Refer to Section VI BOILER PIPING
** Relief Valve discharge and drain valve piping
should be piped to a safe place of discharge.
