Water Piping Notes
1) A manual water control valve must be placed upon the water inlet connection to the
Continuum 2424WC before it is connected to the water line. Unions may be used on
both the hot/cold water supply lines, for the future servicing or disconnection of the unit.
2) All soldering materials and piping must be compatible with potable water.
3) Purge the water line to remove from it all debris and air. Debris will damage the
Continuum 2424WC.
4) There is a wire mesh strainer on the Continuum 2424WC's inlet to discourage the
introduction of debris to the unit. It will need to be cleaned periodically.
DO NOT operate unit without filter in place.
WARNING: DO NOT reverse the inlet and outlet (cold and hot water) connections on
the unit. This would cause the Continuum 2424WCto operate dangerously or not at
all.

Pressure Relief Valve
1) ANSI code calls for the addition of an approved pressure relief valve to all water
heating systems.
2) The pressure relief valve must meet the following criteria: The relief valve must
comply with the standard for Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems ANSI Z21. 22. This relief valve must be rated at 150
PSI of pressure.
3) The relief valve should be added to the hot water outlet line per manufacturer's
instructions. DO NOT place any other type valve or shut off device between the
relief valve and the hot water heater.
4) The discharge from the pressure relief valve should be piped to the ground or into a
drain system to prevent exposure or possible burn hazards to humans or other plant
or animal life. Water discharged from the relief valve could cause severe burns
instantly, scalds and/or death.
5) Do not plug the relief valve and do not install any reducing fittings or other restric-
tions in the relief line. The relief line should allow for complete drainage of the
valve and the line.
6) Pressure relief valve must be manually operated once a year to check for correct
operation.
7) Should overheating occur or the gas supply fail to shut off, turn off the manual gas
valve on the Continuum 2424WC.
