ASME addendum
Installation & Operation Manual
1. Heat exchanger
Allows pool water to flow through specially designed tubes for maximum heat transfer, while providing protection against
flue gas corrosion.
2. Outlet temperature sensor
This sensor monitors outlet water temperature and will shut down the unit if this temperature gets too high.
3. Inlet temperature sensor
This sensor monitors the inlet water temperature and will be used by the integrated control to determine whether an ignition
cycle should begin.
4. Water outlet (pool supply)
For an ASME unit, connection to the pool heater can be made with either 2" threaded pipe or a slip connection with 1 1/2"or
2"pipe.
5. Water inlet (pool return)
For an ASME unit, connection to the pool heater can be made with either 2" threaded pipe or a slip connection with 1 1/2" or
2" pipe.
6. High limit sensor
Device that monitors the outlet water temperature. If the temperature exceeds 175°, it will break the control circuit,
shutting the pool heater down.
7. Pressure relief valve
A pressure relief valve is installed in the vertical position and mounted in the front header on the hot water outlet
of the pool heater. To prevent water damage, the discharge from the relief valve shall be piped to a suitable floor
drain for disposal when relief occurs.
8. Pool heater drain port (total of 3 - not shown)
Location from which the heat exchanger can be drained.
