How to Connect a Condensation Pump on a Furnace

Furnaces produce condensation as part of their normal functioning, and if this condensation is not removed from the furnace, it can extinguish the furnace's pilot light and cause other problems. Normally, furnaces are installed above a condensate drain and the condensation is simply diverted into the drain. When this is not possible, however, a condensate pump can be a useful means for eliminating condensation from the furnace and directing it into the condensate drain.

PVC pipe or flexible tubing
Plastic tubing

Instructions

- 1
  Place the condensate pump in an ideal location. The pump must be close to the furnace itself, but also located close enough to the condensate drain to minimize the amount of tubing needed to connect the two. Place the pump close enough to an electrical outlet that the pump's power cord can easily reach the outlet.
- 2
  Connect the condensate outlet on your furnace into the inlets on your condensate pump. Some models of condensate pump feature several inlets for convenience; simply choose the one that involves the least amount of PVC or flexible tubing.
- 3
  Connect discharge tubing from the condensate pump outlet to the desired condensate drain. Use plastic tubing unless advised to use another material by the manufacturer's instructions.
