    I am installing an Englander 25 with a Dura vent flue kit. On the outside of the house, do I cut the siding around the square thimble, or do I screw the thimble over the vinyl siding and seal with silicone? Thanks for your help.

    Either or so long as the clearance is maintained.

    They should offer a vinyl stand-off kit. We got lucky here, we were having the vinyl siding done on the building. So we cut our holes and sealed everything up. Then the guys just went around the thimbles and cleaned them up real nice.

    I put mine outside the siding, and placed under the lip, and put silicone all around and screwed it to the wall, Just maintain your clearance or better.

    If you look at your thimble it will tell you what clerance is required, mine was a 3" vent pipe with the thimble it was a min of a 7/12" hole I made mine about 9".

    the flanges on the thimble covers everthing.
