Some applications (such as garages) may require that the heating appliance be elevated in
order to meet building codes. The Steffes Comfort Plus stand elevates the 4100 or 5100 series
Comfort Plus system 18". This stand is shipped as a kit and requires field assembly.
liftinG HanDleS
To make it easier for installers to handle and
move the Comfort Plus furnaces, Steffes offers
special lifting handles designed specifically to fit around the furnace’s
brick storage module. The handles allow 2 to 4 people to more easily
lift the furnace and move it to its installation site.
Comfort Plus Hydronic Optional Accessories  2.02
air HanDler
The Steffes Air Handler is an optional device designed to interface to
the Comfort Plus Hydronic (5100 Series) furnace to allow it to pro-
vide forced air heating as a stand alone furnace or as a supplement to
other ducted heating systems such as a heat pump. When used with a
heat pump, it allows the Comfort Plus Hydronic furnace to serve as the
back-up heat source and to provide comfort modulation. The Steffes Air
Handler includes a return plenum, supply air blower, water coil, and air
filter. It is painted and fully insulated. The Air Handler attaches directly
to the right side of the Steffes furnace.
 ½ HP configuration can accommodate most 1.5 to 4 ton heating/cooling coils
 1 HP configuration can accommodate most 3 to 5 ton heating/cooling coils
 The 1 HP air handler 90,000 BTU/hr water coil output may decrease when using heating/cooling coils smaller than 5 tons
 External static pressure should not exceed .75 inches water column.
 When interfaced to a 2-stage air conditioner or heat pump, the ECM motor will operate at 70% of the selected air flow in
low speed (Stage 1) compressor mode. If 50% air flow is required in low speed, a Stage 1 speed adjusting relay must be
installed. Steffes recommends the Allen Bradley Relay #700-HA32A24 with Relay Base #700-HN125 or equivalent.
