Anyone familar with Power Vent W/H? Fan question

Hi- Fan on top of water heater. I can feel cool air coming from the seams around the fan housing when its running.

Is it normal to sense air around the fan / motor housing?

The fan has an air intake...( Maybe thats what you are feeling?

But what seams/seals are you talking about? The vent seal from the exhaust pipe? Or the fan seal on the water heater where it meets the fan?

No exhaust gases should be leaking out...

Below is a photo of where I feel air blowing. The air I feel is a consistent room temp. throughout the entire cycle, not warm or hot that you might associate with combustion and not warm at all like the PVC or bottom of the fan feels when its heating. It doesn't appear to be coming from the rubber coupling either.

So its the plate that the motor is screwed too. The backside that you cant see in the photo (closest to the center vent is and where the makeup air vent is) has a gasket (which you can see in photo). The front side where I feel the air doesn't appear to have a gasket I can see nor could you open the fan up that way.... the side with the gasket is the side that unscrews.

Also the air is not coming from the cylinder motor with the squres/louvres you could see the motor windings thru.

If its coming from where you show thats fine. Normal...

Most manufactures make you install a short piece of 3" before reducing to 2"

But that may be the manufactures coupling there..

Can you tell me make and model?

Great, you think that's normal then. Just curious, whats your reasoning?

BTW: This is the model STATE GS6 50 YBVIS. That coupling is the manufacture coupling and since the venting system is small enuff its 2".

p.s.- When I was calling the side of the fan with the gasket the backside, actually that would be the front maybe since that's the side that collects the exhaust. Where I feel the air, that the back of the fan side (motor side).

Not trying to confuse matters although it probably sounds like it!!!

Lawrosa- I just took a closer look with a flashlight and what I am feeling is air from a small fan that is mounted between that blower housing and the cylinder motor. I suppose its to cool the motor.
