or on the ceiling rafters. Note that the platform and the ceiling rafters must be able to support the weight of the furnace being installed. It can also be suspended from a ceiling in a basement or utility room in either a right to left airflow or left to right airflow.

When installed horizontally, the furnace must be raised above the surface to allow a drain trap to hang vertically below the furnace. This will allow for proper drainage of the condensate from the furnace.

Conversion of the 90+ Upflow Furnace for a Horizontal Right Installation.

1.Remove the hard “J” tube drain trap as- sembly.

2.Place the 5/8” cap plug over the drain tap in the header box from which the “J” drain trap assembly was removed.

3.Remove the piece of soft tubing running from the in-line drain assembly to the header box and place a 1/2” vinyl cap over the drain tap in the in-line drain assembly.

4.Remove the grey tubing from the pres- sure switch to the header box. Remove the 1/4” cap from the pressure tap on the right side of the header box and place it on the corresponding pressure tap on the opposite side of the header box.

Conversion of the 90+ Upflow Furnace for a Horizontal Left Installation.

Refer to Figure 4 for details and description of parts required for the horizontal left conver- sion.

1.Remove the hard “J” tube drain trap as- sembly.

2.Ensure that the piece of soft tubing run- ning from the in-line drain assembly to the header box is in place with the drain oriented downwards (See Figure 4).

3.Connect a draw trap to the right side of the header on the furnace. The drain trap must be installed according to local code. NOTE: A downward slope must be maintained on the tube as it is routed through the furnace (when the furnace is in the horizontal position).
