Comfort Plus Hydronic
SINGLE ELECTRICAL FEED KIT
The Steffes Comfort Plus systems have built-in circuit breakers. They are factory
configured to be field connected to multiple line voltage circuits. If single feed to the
element and blowers/control circuits is desired, the single feed kit is available to allow
the system to be powered with a one, larger line voltage circuit. Contact the factory for
ordering details.
When using single feed, the neutral conductor MUST be sized in
accordance with all applicable local, state, and national codes and
regulations.
PRIMARY LOOP KIT
The Comfort Plus Hydronic system requires a primary water loop which serves to regulate heat transfer from the
unit
’
s heat exchanger. To minimize installation time and costs for field design and engineering of this loop, Steffes
Corporation offers a primary loop kit. The kit contains the components generally installed with hydronic heat systems.
Features:
Includes a 5-gallon diaphragm type expansion tank, Grundfos brand pump
(circulator), air separator, air vent, pressure gauge, and pump connection
conduit and fittings.
Contains the appropriate valves to bleed air from the system during filling along
with automatic purge during system operation and draining.
Incorporates isolation flanges for quick and easy servicing of the primary loop
pump (circulator).
Offers troubleshooting isolation between the heating system and secondary
zones.
AIR HANDLER
The Steffes air handler allows the 5100 series heating system to
provide forced air heating or to be interfaced with other ducted heating
and/or cooling systems such as a heat pump or air conditioner. When
used with a heat pump, it serves as the back-up or supplement heat
and provides comfort modulation. It
’
s duct sensor monitors outlet air
temperature and modulates the off-peak stored heat needed to
maintain the desired output air temperature. As the air handler is
attached to the Comfort Plus system, it also directs the heat lost
statically through the outer panels into the ductwork for delivery to the
living space (automatic static heat recovery). The Comfort Plus
system
’
s internal controls automatically regulate the air handler
’
s
operation.
