At Lindemann Chimney Supply we like to pass along tips to our customers who are installing stainless steel chimney liners. Here are some tips, below, for attaching insert boots and connecting the stainless steel chimney liner:
Some installers use stove gasket cement to glue stove gasket to the bottom of the insert boot to create a better seal.
Some boots such as the ICO Adjustable Boot, above, has a clamping system that attaches it through the insert collar.
For insert boots that have to be attached to the insert a cobalt drill bit will do a quicker job.
To secure the insert boot you can either use bolts and nuts. Another way is to pick up a tap and die kit. After drilling the correct size hole (as mentioned in the tap and die kit) then use the kit to thread the holes and attach the boot with screws.
Stove and gasket cement can be used to seal where the insert boot meets the stove and where the pipe enters the collar. However, this will make future removal more challenging because it sets up hard.
Never use silicone sealant to seal an insert boot. It wont withstand the temperatures.
If you are attaching the boot to the insert first then don’t forget to predrill the holes in the liner so that when you pull the liner down into the boot all you have to do is line up the holes and attach.
If you are attaching the boot to the liner ahead of time make sure you have room to push the liner up a little to clear the insert when it’s pushed back into the opening.
If you attach the liner to the boot ahead of time make sure you predrill the holes into the insert so you can line everything up and attach the screws or bolts and nuts.
We provide boot dimensions in our catalog so you can anticipate whether the boot will clear the lintel in situations where you attach the boot ahead of time.
