B1. CDB1 HORIZONTAL APPLICATION

The CDB1-50, 75, 100, and 125 furnaces may be installed in a horizontal position by placing the furnace on the left
or right side (as viewed from the front in the upright position).

For left or right horizontal applications of the CDB1 series units, the rollout switch located on the burner box must
be moved to the pre-punched mounting holes on the side of the burner box. Screws are provided in pre-punched
holes at the required limit location. Remove these screws and use them to mount the limit to new location. Utilize
previously removed limit mounting screws to fill voided holes at previous limit location (See Figure 1).

For a right side horizontal application of the CDB1 series units, the hose from the single tap pressure switch (top
switch) is already connected correctly (See Figure 1).

For a left side horizontal application of the CDB1 series units, the hose from the single tap pressure switch (bottom
switch) must be moved to the lower front tap on the face of the collector box. Use the black cap removed from this
tap to plug the original pressure switch tap.
NOTE: The hose, when moved, must be shortened (cut) to ensure that no excess hose exists to cause a sag, loop, or
"water trap".

For a right side horizontal application of the CDB1 series units, the auxiliary limit switch located on the right side of
the house air blower must be moved to the bracket on the opposite (left) side of the blower (See Figure 1).

NOTE: When the CDB1 is installed as horizontal unit, it is imperative that the auxiliary limit switch and bracket be
located on the upper side of the house air blower; the burner rollout switch located on the burner box be relocated to
the side of the burner box; and that the hose from the single tap pressure switch be connected to the lower tap on the
front of the collector box (See Figure 1).
