Stainless Steel Flue Liner Replacement
There are times when the current chimney liner is beyond repair. That is when we recommend stainless steel liners as an alternative for chimneys and fireplaces if they are good candidates for this option. We also recommend and use stainless steel lining kits (full kits) for a direct connection to wood stoves. Ask us about the life time guarantee!
Here is an overview of the different Stainless Steel types we use:
- 316 Type stainless steel – can be used for wood burning, coal burning, oil burning and category 1 gas. (This is what we use 95 percent of the time due to the wide range of fuels used in fireplaces / chimneys.)
- 304 Type stainless steel – would be used by us for solid fuel burning conditions (pellet stoves, wood stoves, open wood-burning fireplaces) only. The reason is a lot of consumers tend to convert to gas. One might think that the ideal material for these liners would be 304 stainless steel. Well, the flexible pipe manufacturers tried this, and the chlorides in the exhaust vapor of natural gas caused corrosion.
Any time we install a stainless steel liner, whether we take out the existing flue tiles or not, we insulate the liner with an approved insulation mix or insulation blanket. The insulation mix has to be poured around the liner at a minimum one-inch thickness. The insulation blanket has to be a minimum of ½-inch thickness or a minimum of ¼-inch thickness depending on the situation. Insulating the liner is an important step not to be overlooked in the process of replacing or adding a stainless steel liner to your chimney system.
If you are not sure you need a new liner or need a second opinion, call a certified technician from Owens Chimney Systems to inspect your chimney today. We can provide to you digital pictures so you can see the damage and see the problems first hand.
