Stainless Steel Chimney Liners

Hi Dorothy,
If you are installing a STEAM boiler,the IN5 also is avaiable as a power vent model. In this configuration you would not need to use your chimney at all, just vent out the side of the house through SS pipe.
I went this route when I got the quote for a liner install. Not sorry I went for the power vent.

Chimney Liners

Hi all.

So i will be getting a new boiler and the installation guy is requesting that i get my chimney relined.
My question is that some shops are giving me 6'diameter stainless steel lining and some are giving me 5 1/2'.

For the 5 1/2' opening, the guy is telling me that the drafting wont be much of a big difference. I need 25' ft of lining.

is he telling the truth?
Thanks

it depends

on the boiler's output, Dorothy. It is not uncommon to see a 5" liner used on a 6" boiler vent (oil). Something to do with keeping the exhaust velocity up, if you will. Most liner co.'s have charts for acceptable liner diameters. Why not tell us what boiler you have and it's input/output? Is it oil or gas?

Question

If you don't trust your installer why are you having them work in your home?

Dorothy....meet Goldie Locks!

Goldie Locks Saves the Three Bears from Certain Asphyxiation!


Goldie Locks Saves the 3 Bears from Certain Asphyxiation: The last time we saw Goldie Locks, she was a mere child being chased around by 3 bears. But alas, Goldie has grown up and is now an appliance installer. As we peek in on Goldie Locks, she is attempting to connect a furnace to one of three vent pipes in the three bears house. The first vent pipe was toooooo small, the second vent pipe was toooooo big, but the third vent pipe was just right. At one point we were simply worried about vent pipes being big enough but as technology has progressed, we are now worried about vents being too big. Vent pipes for new Federally mandated mid-efficiency appliances have to be "just right" When a vent pipe is too small there isn't sufficient area to vent the products of combustion. When a vent pipe is too big it will be subject to excessive condensation. The corrosive nature of this condensate will cause the vent pipe to deteriorate. This issue, as well as the dangers associated with vents and chimneys that don't funtion properly have led to incresed concern about using existing chimneys and vents when appliances are being replaced. You have probably seen some articles on the subject. An article called "Carbon Monoxide--The Silent Killer" , "Danger Lurks in Local Neighborhoods: Dangers of Carbon Monoxide," written by George E. Lucia and Trica Branley of Hillsboro, NJ and it appeared in the Feburary 1994 issue of New Jersey Municipalities Magizine. Both of these articles are worth reading. Some questions I ask as a aplicant who is proposing to use an existing chimney or vent with a replacement appliance are: 1. Is the chimney/vent clear and free of obstructions? 2. Is the chimney lined, and is the liner in good condition? 3. Is the chimney/vent size appropriate for the new appliance? Often it is not possible for an inspector to see the inside of the flue or chimney. In most cases, an inspection is done after the new appliance is installed. For this reason getting some certification about existing conditions from the installer probably makes sense and is in fact code in the great state of New Jersey (counter form: F370). In addition, a spill test performed by the contractor should be performed. If possible, this spill test should be witnessed. We now return to Goldie Locks, who has just completed the furnace installation in the 3 bears house. The 3 bears are so happy with the installation that they don't chase Goldie Locks out of the house, but rather, invite her to sit down and have some porridge with them. And they all lived happily ever after--untill the bears got the bill. Papa Bear thinks Goldie Locks' prices are toooooo high! The End.............

Each liner company.....

.... has specs in regards to sizing their respective liner. It all has to do with BTUH input, efficiency of the boiler and height of the chimney.

The boiler brochure normally specifies what diameter the chimney liner should be. Your boiler installer should have that info.

Boiler that is being installed is the Burnham IN5.
the manual recommends 6' diameter piping, but the chimney man is saying that probably wont fit due to flue in the chimney. To fit a 6" diameter liner in there, he has to chip away at the old clay flue which i suppose he doesnt want to do.
i guess my concern is will this draft properly since its a 1/2 smaller?

Thanks.

well it would also depend on the dimentions of her chimney..

Your best bet is to call Burnham and ask as the manual says minimum 6inch at 15 feet so given tghat the only ones that can ok the 5.5 inch liner is Burnham 888-432-8887.
