Hey all- I am planning on putting in a vented gas insert in one of my 2 fireplaces. I already have the gas and electric run. I need to understand one thing though. How do you add the cap for the gas fireplace when you have an existing cap like i do? Covers all three flues and seems like its cemented in. We do not burn wood in any of the fireplaces and the 3rd is a vacated capped exhaust from the old furnace that was replaced with a newer one vented out the side of the house.
Do i just cut a hole in the existing cap to fit the gas fireplace cap and seal it with the correct sealant so water doesn't get it but it will handle the heat?
It would be the flue all the way to the right. TIA!
