exhaust modifications

What is the proper way to mod. your exhaust on pw for you dont get a improper flow and lose hp or fuel consumption...

Currently I have my running out towards the back door, but you still have a fire hazard and poison gases from the exhaust entering the trailer...

I would like it to go down through the floor, so its vented, or would it be better to take it through with the stack....

Thru the floor or thru a stack is both good. If You go thru the floor make sure the tail pipe sticks out of the side of the trailer so the fumes don't rise up inside.

I have my Powerwasher vented thru the top of the trailer and my engine exhaust vented out of the back. A better way that I will do one day is vent the engine exhaust right thru the stack.

Here's a picture of the inside of my enclosed trailer. You can see the exhaust pipe sticking up and out over the reels.

Nice hose reels. What brand are they and how much hose do they hold?

Those look like Hosetract reels, or whatever it is that E-spec is selling. They use nylon bushings for bearings, and after a while they split and fall out so there is no bearing, at least from my experience. I prefer Cox or Hannay.

So I am assuming that you can put any length of pipe out your muffler and not have a large bend or turn to damper exhaust flow you should be alright...

What do you have John for thr top of your flue stack, just a standard cap....

I bought a hannay for 218.00, holds 450 from dultimeier...

Have Rob Fitzgerald post a picture of how he has his machine vented throught the roof of his van. He has a nice setup. I told him I would also vent the muffler into the burner stack also. A muffler shop should be able to do that with no problem. He has a Delco machine.

Steve,
Those are Hosetract reels. I have about 400' of PW hose on it. I believe it could probably hold 500'. They work like a charm and I had no problems with these reels. The hose reel stack my father made. I don't think Hosetract had a stack for these size reels at the time when I bought them.

Mattia,
I paid around $300+ for the stack pipe and cap and installed it myself. I'll have to get a picture of the cap. I forgot the make of it but none of it was cheap considering the short length of the pipe.

I bought all of it from a plumbing store. No Home Depots crap here.

He did a good job on the rack. A friend made mine out of 2" angle iron also and put wheels on the bottom so I could roll it out with the hot unit I have. It works well for me. There are a lot of driveways that are not as long as my rig so I park on the street and roll everything right up to the house.

When venting a diesel burner never go smaller in size than the output diameter of the opening. If you do it will cause soot build up. Sharp turns are not recommended. Some manufactures will have one bend on the output to divert the output.

It has been my experience that when venting an oil fired burner, you do want to stay at the manufacturer's stack dimension. However, it is imperative to have an air gap at the machine leading into the stack. I usually use a bell shaped adapter to go from a size larger than the stack to the actual pipe diameter. The hot exhaust coming out of the machine will cause a natural draft up the chimney. The 1/5 hp motor on a burner is there to drive a fuel pump and push enough air to mix the fuel properly. It is not designed to push a column of air up a stack and out to atmosphere. The bell adapter must be suspended or supported so there is about 1" - 2" of air gap at the bottom. I have seen many coils soot up to the point of total closure just because the blower is trying to do double duty. An in stack damper like on a house furnace will work, too, although it's more expensive.
