4.3 HORIZONTAL
Horizontal application is perfect for ceiling installation.
Allow enough space for inclination of the furnace and
drain trap.
Figure 12 will help you figure orientiation,
inclination and space needed.
When installing the furnace in horizontal orientation
you must tilt the furnace at least 0.5 in torward the
heat exchanger to ensure proper drainage of the
condensate. See figure 12
4.3.1 Horizontal Condensate drain
connection
1. Remove PVC tubes from the ID blower, condensate
box and vent collector and block the openings with
furnished ½” black caps.
2. Use the furnished extra tubing and cut those 4
lengths : (1) 3.75" , (2) 5.5" , (3) 5.5" and (4) 3.25".
3. Remove the appropriate knock-out for drain trap. It
is on the top of the furnace. Refer to Figure 4, and
look for horizontal drain trap location.
4. Cut open the pressure port, located on the
condensate box behind the inducer. It will be
connected to the multiposition pressure switch in
section 4.5. For pressure port location see figure
14.
