Hi guys I'm new to the site and need to bone up on just how these EFM units work... it's all new to me. I picked up a used DF 520 that I plan on using to heat my new shop. The shop is 40 w x 80 l x 20 h with R 19 in the walls and R 30 in the ceiling. To start with I will only be heating 1/3 of the shop with the boiler by way oh heat exchangers. My first question is must I use a 8 " smoke stack or can I down size it to 7". I salvaged about 18' feet doubled wall 7" from a building that was going to be leveled. If not I'll just try to sell it and get the 8".

Thanks

Thank you for the warm welcome lincolnmania. Do you think that the 7" smoke stack will be OK?

Hi and welcome. Let's put it this way: If you go to the trouble of installing undersized pipe and you have a CO problem, do you really want to replace it with the proper sized pipe?

It's a close call. It might work and it might not, depending upon your draft. I'd be tempted to try it in my own shop, but officially, it must be 8 inch pipe.

Stoker-Man thank you for your incite!!!
What are my options with regards to stack piping?
Do I have to use double wall piping?
Keep in mind that all the stack piping will be inside the building.

Single wall 24 or 26 guage pipe is fine for indoors, keeping combustible clearances in mind.

OK so I add a slide show of what I'm working with so hopefully it will work. Just click on the picture and it shoutd start and at any point you can click on any picture and it will enlarge it. Where do I start :?

Download the manual of the DF520 off the efmheating.com website. It will answer most of your questions.
