IMPORTANT!
With electrical power supplied to the Cont inuum 2424, it will not freeze in environments as cold as -30ºF, when protected from direct wind exposure.
In the event of a power failure at temperatures below freezing, the Continuum 2424 should be drained of all water to prevent freezing damage.
The unit may be drained manually, or through the installation of the Optional solenoid valve drain kit shown.

IMPORTANT!
With electrical power supplied to a Rinnai water heater, it will not freeze in environments as cold as -30ºF, when protected from direct wind exposure.
In the event of a power failure at temperatures below freezing, the water heater should be drained of all water to prevent freezing damage.
The unit may be drained manually, or through the installation of the Optional solenoid valves as shown shown.
The electrical connections for the two solenoid valves should be tied to the 120V power terminals provided on the PCB of the water heater.
When the electrical power to the water heater fails, the 3/4" solenoid valve closes (stopping the flow of water into the heater) and the 1/2" solenoid valve opens (allowing the water heater and associated piping to drain. Insure that you run the drain for the solenoids to the outside environment to prevent discharging water inside the building, causing water damage.

1. Disconnect power to Rinnai water heater.2. Close valves V3 and V4.3. Connect pump outlet hose H1 to service valve V2.4. Connect drain hose H3 to valve V1.5. Pour approximately 4 gallons of virgin, food grade, white vinegar (or virgin, food grade, citric acid) into pail.6. Place free ends of hose H2 and H3 into pail.7. Open valves V1 and V2.8. Turn on power to circulating pump and allow solution to circulate through water heater for 45 minutes.9. Turn off power to circulating pump.10. Remove free end of hose H3 from pail.11. Close valve V2 and open valve V4, only. Do NOT open valve V3 at this time.12. Allow water to flow out of hose H3 for 5 minutes, rinsing cleaning solution from water heater.13. Close valve V1 and open valve V3.14. Disconnect hoses H1 and H3 from service valves.15. Remove in-line filter from water heater cold water inlet and clean out any residue. Place filter back into unit.16. Restore power to water heater.
