Type \"L\" vent

Joel_3

Ok "all fuel" pipe is wicked exspensive and overbuilt for typical oil work. "L" vent is UL approved for high eff oil up to 580F continous stack 1700 for 10 min overfire protection. Sooooooo who's used it? how did it work out?? Never seen in it in this here woods but I'm mighty interested especially since you can get it in small sizes like 4" and 5" . looking for feedback ASAP thanx!!!!!

Class 1 chimney vent

I've used Class 1 vent (Metalbestos) on many installations. It does the job. Yes, it's not inexpensive. We size the vent to the input of the oil appliance, using the manufacturers' charts.

I used one...

in a direct vent(balanced flue) application on a 90 turn where I had a problem with clearance to the floor above as I went through the sill. The fire inspector had given me a hard time before but himmed and hawed and let me do it that way.( he could not find a code that prohibited it). I have not had any problem to this day with that boiler install.

L-Vent

It's used a fair bit up here in the north when the cost of 'A' vent becomes too prohibitive to the customer. I have it personally at home on my oil fired (ouch) furnace. It's never been a concern for inspection or performance.

All - Fuel vent

This stuff works fine, but I also use a post & pre purge control to help draft on start-up.Cost is still cheaper than burning down the house. Good luck
