Direct Vent Pipe Length

i will be installing my direct vent koker in my basement, is there a max length of pipe inside the house?

Initially the installer told me he wanted to keep the horizontal run to about 12 feet. We ended up with 1.5 ft vertical run out of the top vent , then a 12.5 ft horizontal run to the block wall. This was done using 4" stainless steel pipe.
I hope this helps.

on my keystoker DV, I think I have about 8' vertical run and 6' horizontal run to the outside, Just make sure you adjust your draft accordingly...

With a long horizontal stretch of flue, you will accumulate fly ash quite quickly,, I would inspect the flue pipe every month for the first several months to learn just how much and how fast the ash fills up the pipe.
The rate and amount will depend on the weather, therefore the amount of coal burnt and ash produced..
You may want to plumb the flue with a 'TEE' in place of an elbow, and cap the unused leg of the 'TEE'. This way you can remove the cap and shine a light in the flue to inspect for ash accumulation. You can also just use a shop vac with extension tubes to vac out the flue.

Hope this helps.. Greg L

Using the tee instead of an elbow is a good suggestion. That's what we did on mine and that's why we did it. Because it's a direct vent, there's a positive pressure in the pipe. This requires all the vent pipe joints to be sealed. The less intrusive I can be when inspecting and cleaning the pipe, the easier the job will be. Having the cap on the tee as the only thing I have to open up is a good idea.

nice and shiney looks real good.
