I had the hood installed to be vented to outside. Air blows out the top vents. Very loud clicking on 3rd speed. ????

Call the person who installed it and have them fix it. They most likely did not remove the blocking panel that opens the hood to the outside vent. The instructions are pretty clear that you need to do this or else it will simply blow air back in your face. The clicking is probably a similar issue - that your installer didn't open it up and put the right panels in place and remove the securing packing tape.

Exhaust vent out the top, vertical up. No power involved at all. See those slots in the side of the device?? Thats where air goes in so keep them clear

You want the fan to push the air out of the exhaust vent. On my fan, the housing outlet is positioned so that if the fan turns one way, the air is blown into the outlet. If it turns the other way it isn't and the fan is less effective. I suspect most housings are similarly designed.

There was one of these in the home I moved into last year. It worked well enough, but the vent fan sounded like a jet engine. Also, there seemed to be no noticeable sound difference between high and low. My model was made in 2006, so I'm not sure how much they've improved this since.

flip the fan over -- the fan doesn't know the difference. It exhausts air or evacuates (sucks) depending upon how it's installed.

For anyone else that is interested, I got a response from MetroVac already. They said, "It is normal for venting thru housing to avoid overheating."

Make sure that the venting is correct. The combustion air and the exhaust are both in the top vent. What is the error code that is displayed when it cuts out? Was it installed by a professional?

it will smoke through the vent...which is the stuff and moisture you are burning off which comes out of the ac system

I drive wiyh mine all yhe time at those speeds. It has been about 9 months since I installed the top. The only issue I have is one of the side window channels unhooks partially once in a while. It is probably an incorrect adjustment on my part. Had a foot of snow on it the other day and no worries. Hope that helps your decision.

I had to use a reducer for mine so check ur pipe size carefully, took it off after two weeks the sound was an annoying pitch and I saw no performance or gas mileage difference worth keeping it on ( can't even sell it for $20 to anyone ) I would look to another manufacturer

Do you hear the motor speed drop as well? And are you running the hot air rework at the same time. It did it to me the other night I had the iron, rework wand, and the smoke absorber on all at the same time. And when the heating element kicked in my air would drop. Then come back when the iron turned off, then start again when the iron needed to heat. Did you remove the red plug from the bottom? And if that fails crack it open and see if any lines are loose, or cracked. If all else fails write me back and I'll help ya more if I can.-patrick

The sensors might be dirty or perhaps the unit is too close to a vent or air source. I took the front panel off of mine and blew on the sensor then relocated it slightly. It hasn't happened since.

You need to vent it outside so the hot air has somewhere to go. A window is the easiest.

Mine seemed to take a few hours to really start to cool everything down, but it works perfectly now. Make sure it has the proper exhaust ventilation.

Not sure what you mean. The exhaust breath goes thru center round vent when exhaling. I put my hand over it to seal the outer edges when using. This blows air out around your face to check seal.

Pop the hood! Do you see a carb or a throttle body on top of your engine! If it's 88 or newer probably tbi

Yes, I did the same thing. The vent was movable to blow from back or the top of the unit.
