## Overview

The GenExhaust Universal generator exhaust system features a robust double-wall stainless steel design with welded seams to prevent leakage and withstand high temperatures. It fits 1" ID steel flex tubing and includes slotted mounting plates, a galvanized u-bolt clamp, and a ventilated bracket with a 3/4" air gap to reduce heat transfer and ensure safe, efficient exhaust through walls. Ideal for professional-grade generator enclosures requiring durable, safe, and adaptable exhaust solutions.

## Description

This all stainless steel double wall constructed universal wall attachment kit provides of method of emitting the combustion exhaust out of your unoccupied generator enclosure for any 1” ID steel tubing exhaust kits. The inner pipe is 13” in overall length with a slash cut 3” long exterior end for prevention of weather penetration and a double wall section to pass through the enclosure wall. Interior attachment length of the 1” exhaust pipe is an approximately 1” long section. The outer pipe is 1-1/2” OD and 8-3/4” long with about 8” going through the wall. The 5” X 5” mounting bracket has 4” X 4” hole spacing for 5/16" diameter bolts/screws/threaded rod attachment that you supply depending on application. It is formed with a 3/4" air gap to reduce the amount of contact area and also to provide an air gap for cooling between the bracket and the exterior wall. The bracket also has a series of holes on the outside to vent the space between the two walls of tubing.

Review: Quality Product - Great product. I built a generator room in my detached garage and was looking for a way to run the exhaust outside. Done a search for portable generator exhaust on desertcart and came across this item. So glad I did. It’s made of good quality material and craftsmanship. Worked perfect for what I was doing. In my case I had to pass through an 8” block wall. I put a 2” sleeve through the wall, then installed the exhaust pipe through the sleeve. (You don’t necessarily need a sleeve in a block wall but I think it made for a better installation). I also built a generator room for my neighbor in her detached shed. In her case the exhaust pipe had to pass through a wood stud wall with vinyl siding on the exterior. I installed a 2” sleeve over the exhaust pipe for more air circulation around the exhaust pipe since I was dealing with flammable materials. The tail pipe already has an outer sleeve welded on it from the manufacturer but as added insurance I add the 2” sleeve. Worked great and looks great. (I did caulk the gap between the wood and vinyl siding in the photo). I would highly recommend this product.
Review: Good Quality part! - Works with the WGEN11500TFc Generator and a one inch exhaust extention ment for a Firman Generator.

## Questions & Answers

**Q: On a duromax xp12000hx will i have to remove the generator's muffler to attach a 1 inch flexible pipe to go to this exhaust pipe, how can i connect?**
A: This "through the wall" device does not connect to the generator.  You drill/cut a hole through the building wall, install this in the hole, then use a flexible exhaust pipe and the appropriate fitting (bolted onto your generator's muffler output) so you can route the exhaust out of the building.  This does not physically connect to any generator, it connects to an exhaust pipe/exhaust tube that comes from the generator.

**Q: What all is included in the sell?**
A: This listing includes the through wall assembly, the two flat plate (that can be used as supports on the inner mounting surface), and the clamp. All these items are in the main photo.

**Q: I have genexhaust 1" steel exhaust extension, will this work to attach them together ?**
A: I'm not sure what you're asking. The extension I hooked up for my brothers garage was used with a 1"  flex steel  5'  piece. Then clamped on his generator. We wanted that the generator could stay in place for snow storms. This is for venting thru a 6" wall. This unit is then hooked to that 5' flex pipe.  The flex pipe inside the garage isn't insulated but makes it warmer when freezing out. Nice for when gassing the generator. I also wrapped a thin layer of exhaust pipe insulation for leak prevention. He went through a one week, twice without power both times with no problems. The main thing is no exhaust leaks without ventilation!

**Q: Can this be used to vent a generator inside a cargo van?**
A: Using an appropriate hose and fasteners, you could probably use it to vent through any wall less than 5" thick or so, including a cargo van. HOWEVER, a cargo van has a small airspace, so if your connections leaked even a small amount, it could quickly become deadly. You would at least want a CO detector in there if humans or animals are present.
