INSTALLER’S INSTALLATION INSTRUCTIONS
Gas Piping Notes
1) A manual gas control valve must be placed upon the gas inlet connection to the
Continuum 2424WC before it is connected to the gas line. A union can be used on
the connection of the Continuum for the future servicing or disconnection of the
unit.
2) Check the type of gas and the gas inlet pressure before connecting the Continuum
2424WC. If the Continuum 2424WC is not of the gas type that the building is sup-
plied with, DO NOT connect the water heater. Contact the dealer for the proper unit
to match the gas type.
3) Minimum and Maximum Gas pressures are listed below:
* Minimum value is for input adjustment
Natural Gas: Minimum 7" WC Propane Gas: Minimum 10"WC
Maximum 10.5" WC Maximum 14" WC
WARNING: Conversion of this unit from natural gas to propane or propane to
natural gas CANNOT be done in the field.
4) Always use approved connectors to connect the unit to the gas line. Always purge
the gas line of any debris before connection to the water heater.
5) The Continuum 2424WC must be leak tested before it is placed into operation.
6) After completion of gas pipe connections, all joints including the heater must be
checked for gas-tightness by means of leak detector solution, soap and water, or an
equivalent nonflammable solution, as applicable. Caution: Since some leak test
solutions, including soap and water, may cause corrosion or stress cracking, the
piping must be rinsed with water after testing, unless it has been determined that
the leak solution is non-corrosive.
7) The Continuum 2424WC and its individual shut-off valve must be disconnected
from the gas supply piping system when pressure testing of the gas supply
piping system at test pressures equal to or greater than 1/2 psi.
8) The Continuum 2424WC must be isolated from the gas supply piping system
by closing it's individual manual shutoff valve during any pressure testing of
the gas supply piping system at test pressures less than 1/2 psi.
9) The Continuum 2424WC's Installation location must provide adequate Combustion
and Ventilation airflow.
