WARNING
General
These instructions are written as if the furnace is installed in an
upflow application. An upflow furnace application is where the
blower is located below the combustion and controls section of the
furnace, and conditioned air is discharged upward. Since this
furnace can be installed in any of the 4 positions shown in Fig. 2,
you must revise your orientation to component location
accordingly.
Electrical Controls and Wiring
Each pressure switch is labeled with the reference location (noted
as “COLLECTOR BOX--LPS” or “HOUSING--HPS” on the
switch). The nominal break point of each switch is shown on the
label below the reference location in inches of water column,
“W.C.” The maximum and minimum break point of the switch is
+/-- 0.05 inches of water column from the nominal break point of
the switch. The maximum make point of the switch is 0.10 inches
of water above the maximum break point of the switch.
Example
: Nominal break point on pressure switch is 0.68--in.
W.C. The minimum break point of the switch is 0.63--in. W.C.
The maximum break point of the switch is 0.73--in. W.C. The
maximum make point of the switch is 0.83--in. W.C.
