Back To Tech Q and A
Question: I am relining a flue with a stainless steel liner for a client because the existing clay liner is now over sized for the new appliance. Do I really need to perform an internal camera inspection of this flue if I already know that I'm fixing it?
Question: I am installing a 6” stainless steel liner in a clay tile lined flue for a new woodstove insert in a masonry fireplace. The flue is oversized, so I am downsizing by installing a full liner. The clay tiles are not cracked and it’s an interior chimney. Do I still need to insulate?
Question:When I have a liner job that requires tile removal I refer it to another company. I'm thinking about adding clay liner removal to the services I provide so that I may keep those jobs. I have done a lot of research, and I've heard some conflicting advice. Should I break tile from the top with my drill and rods, or from the bottom?
Question: If a masonry chimney does not meet current minimum height requirements, do I have to raise the height if I am relining it with a listed liner system?
Question: I recently swept a wood burning masonry fireplace and observed that mortar is missing from the joints between clay tile liner sections in multiple areas. Should I recommend joint repair, or a reline with a stainless steel liner?
Question: I plan to install 2 UL listed stainless steel chimney liners in the same chimney flue, in a residential single-family home application that will serve two separate appliances. Is this permitted without installing a nominal 4" thick masonry wythe or dividing wall between them?
Question: One of our new members we'll call Jim, has a client with a masonry fireplace. It needs a new liner, but the existing clay liner is undersized, and even after the clay liner removal, the chimney won't accommodate a properly sized replacement. Jim wants to know, what are his options?
