On a typical forced hot water system, connect return to inlet side of circulator and supply upstream of re-
motely operated valve. Unit may also be connected to mains of an existing loop system of suffi cient capacity.
Operation will be infl uenced by the system circulator and associated controls.
Installation of a pump and line voltage thermostat will provide the unit with its own “zone” control.
With the addition of a circulator pump, hot water storage tanks may be used (where codes permit) as a supply
source if proper precautions are taken, and if realitively low water temperatures can be tolerated. Be sure tank
can supply additional load of the Twin-Flo and 120° F water. Supply is taken from top of tank, and returns at
the cold water inlet with a check valve. Do not return to bottom drain tapping.
Operation from steam boiler water is entirely possible as long as supply and return connection is installed be-
low level of water line on a steam boiler. This installation requires an optional circulator pump and line voltage
thermostat. Check local building codes.
