Figure 53. Condensate Trap Locations

(Unit shown in upflow position with remote trap)

*Piping from furnace must slope down a minimum of 1/4” per ft. 

toward trap.

Figure 54. Unit with Evaporator Coil

When  combining  the  furnace  and  evaporator  coil 

drains together, the A/C condensate drain outlet must 

be vented to relieve pressure in order for the furnace 

pressure switch to operate properly.
