Is the rubber clamp installed properly between pvc vent pipe and furnance induced draft motor?

Home Maintenance Questions and AnswersCategory: Furnace VentingIs the rubber clamp installed properly between pvc vent pipe and furnance induced draft motor?
Question by Waseem

Few week ago I had the HVAC technician replace the  furnace induced draft motor as previous one stopped working. So the guy replaced the motor but kept the clamp and rubber piece that seals the pvc exaust pipe to the motor from the old motor/install (15 yr old). Due to poor seal the exhaust pvc pipe started dripping water/condensation back in the furnace chamber causing water pooling. Today the guy replaced the rubber piece and newer clamps and the leak stopped coming back from the condensation from the joint of the exhaust flute/pipe.
My question is he put the rubber piece/clamp and it has a indicator that shows air direction but he installed it upside down. Does that really matter if the air direction is inverted on the runner piece? since its just to seal the pvc pipe with the motor pipe outlet. Please see picture link for reference.

Hi Waseem, the rubber piece he used is actually a vent drain kit used in horizontal furnace installations where condensate drain tubing installation might be necessary (it attaches where the yellow caps are. In your case, the condensate drain tube is probably installed at the lower section of the induced draft motor enclosure but I can’t see that on your picture. So, this air flow arrow direction / inverted rubber piece should not impact proper operation of your furnace.

Hello Dariusz…thanks for taking the time to reply. In fact the induced draft fan has two  condensation drain outlets from back side of the motor…. one on top ( near the neck of the pipe) and one at bottom that fit into the furnace itself once the fan is mounted. That contraption goes into the drain pipe within the furnace then comes out at the bottom of the furnace and then to the floor drain and that drain pipe also has a thick end at the bottom in between( assuming that the neutralizer for condensed water) before it drains into floor drain outlet. I will try to post some pictures this evening from my old motor that show the water outlets and water drain pipe coming out of the furnace so it may help someone if they come across similar situation.
Thanks again for the explanation

 I am attaching the pics that show the old blower fan with the vents for evaporation.
