All installations and services must be performed by qualified service personnel.

Equipment must be installed in accordance with regulations of the National Board of Fire Underwriters. Authorities having jurisdiction should be consulted before installations are made.

B. FURNACE LOCATION

: These high efficiency condensing furnaces are not certified for and shall not be vented into a standard or any type of chimney.

The following shall be considered for locating the furnace:

1.For best performance locate the furnace so that it is centralized with respect to the duct system and as near as possible to a floor drain since condensate drainage must be provided.

2.Place the unit so that proper venting can be achieved, with a minimum number of elbows, in accord with the instructions in this manual.

3.The furnace must be located on a level, dry surface. The furnace must be installed so that the electrical components are protected from water. If the area becomes wet or damp at times, the furnace should be raised above the floor using a concrete base, bricks, patio blocks, etc.

NOTICE: Ensure furnace is level after installation to ensure proper drainage and operation.

4.This furnace must be connected to a drain in accordance with these instructions. If it is not practical to connect the unit to a drain, a condensate pump must be used and can be ordered as an accessory, part number 350225. If an acid neutralizer kit is required by local code or the customer, it is available under part number 320095.

B1. CDX1 HORIZONTAL APPLICATION

The CDX1-75, 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 CDX1 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 CDX1 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 CDX1 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 CDX1 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).
