Does the exhaust go into duct for outside exhaust or does it go into attic for dissipation or either?

Either if you want. I wouldn't have it dissipate in the attic as the moisture and mold factor would go up. It's vented through the roof in my house.
164815
It would go either I suppose even though I would not recommend attic dissipation. I bought two of them and went the extra mile installing vents on the roof connecting both ends with aluminum duct hoses. I had them for 8 month now and I'm very happy so far.

The internal fan has a hookup for ducting to dissipate outside your attic through venting. You could leave it n hooked although you will only cause a moisture problem in your attic as you would with any vent fan. This creates mold and rot in the structure and insulation of your home. So, I recommend adding the ducting for proper moisture removal.

It exhausts through piping (i used dryer type), through attic to vent on side of home. You don't ever want to vent into the attic. That can cause all kinds of problems. It's very quiet and looks great. Not a lot of fan power so best for a smaller bathroom. We are very happy with it.

I installed mine and i hooked it up to the existing duct that vents outside....pretty easy

A true vent exhaust should always be vented outside, never into the attic space. You will cause moisture causing mildew and mold into your attic.

Mine vents to a well-ventiliated attic and has been fine, but the unit is designed so you can easily intall duct to go where you need it to.

You can do either. But it depends on your attic spaces and its ventilation. My attic is open with no storage near the exhaust so it's vented into the attic. However, always follow your local codes. Also, this unit is quiet and I like the model.

It is required to be OUTSIDE. The Exhaust from natural gas is pretty clean, yet toxic and being so cleaned you won't noticed you are being poisoned. KEEP IT OUTSIDE. UNDER NO CIRCUMSTANCES SHOULD IT BE IN A GARAGE. I am not yelling, I am just making sure you get it.The plastic is pretty durable, but if you want to extend its life, put a vinyl fence around it for shade. Just make sure to leave enough space to breath and exhaust as well as to do maintenance. Also make sure you instal it with plenty of clearance from the house. At least 3 ft, but check the local code.

I had another fan installed without attic access. However, I have recently learned that the original unit was not ducted correctly, to the outside as i was told, but it exhausts to the attic soffit area, which I'm told will cause frost this winter, and probably mildew and mold, not at all what is wished! So, in that case, yes, attic access will be necessary, but if you already have a fan in the ceiling, and you have a qualified handyman who can do the job, I could be wrong, but it seems that attic access might not be needed, if you are wishing only to switch out your old unit, and to put this one in.

The vent pipe for this unit (bought separately) is actually a pipe within a pipe. The outer pipe draws in fresh air and the inner pipe is the exhaust. As long as you install the vent pipe, route it outside and have access to your gas line (as well as electricity), you can install this unit in a cabinet.

I installed one of these as a bathroom exhaust fan--used a ceiling vent plate that had a 4"duct nipple (you can use an A/C ceiling plate) and then ducted it into the attic to the TD-100 and then more duct to the house ridge vent. I used regular Romex 14-2 with a ground from a timer to the fan. The fan has a connection box on it to make the connections using compression screws that are all supplied.

The ouptut duct for this model is 4" in diameter. If you are replacing an existing exhaust fan, you will probably have a 3" plastic flex duct vented directly into your attic which is not code compliant. Correct way is to replace the 3" plastic duct with a 4" insulated duct and vent to the outside directly.If you use the existing 3" duct, you will have to purchase a 4" to 3" adaptor.Hope this helps.AMGContracting

The vent pipe. Depends on where you are venting and how long the exhaust needs to be.

If you already have an exhaust fan in the bathroom that you're replacing, you can install this model from inside the bathroom. Since the unit is vented, it needs to be piped either through the roof or to an exterior wall. So, if it's a new installation, you'll install the fan/light unit from inside AND you'll have to vent it from the attic to the outside (or you'll create an environment in your attic where the moisture disperses and mold will form.)

only need venting from outside if its a mobile home or trailer. exhaust must be vented out in double walled pipe.

You don't need to install anything. The exhaust pipe is a short plastic pipe, but the air flow is not too strong. I have it in my kitchen and while it does warm up the area, it's not too bad and I never felt like I need to direct the airflow through the window.

It can be configured to vent through the back or the top of the hood. You would have to install the duct and outdoor hardware to complete the job, (not included with the hood). I used it to replace an existing hood that vented out the back into a duct already in the wall and it mated up nicely with the old opening.

No it is made to be outside. It would not have the proper ventilation inside of an attic.

Yes, the exhaust can be vented to the outside of the house. I do not know how many CFM.

Cold air comes out of the exhaust, so, yes, you have to exhaust it outside. You want to pull the inside air as the feed though, so block off the air intake hose.

If the air is coming from the hood, then you know it's NOT ducted. Ducted means the air is pushed through a duct to the outside.

Sounds like you do not currently have an exhaust fan. If you have no working knowledge of electrical circuits, I strongly recommend that you hire a licensed electrician to properly wire the unit. Also, the unit needs to be properly vented. If simply vented into an attic or crawl space, you can pretty much guarantee mold growth. It needs to be vented to the outside.This advice not only applies to this model, but to any exhaust fan that you might be contemplating.

To use it as an an air condioner, you do need to run the hose to the outside. Hot air is vented out thru the hose, and cold air comes out of the vent into the room. When using as a dehumidifier, the exhaust hose does not need to vent outside, but you will get no cooling.
