Direct vent gas fireplace. Truss runs parallel to the back wall about 8″ out. I need to run vent which requires a an 11″ x 11″ hole. Do I notch out the double top plate and drywall nailer on the interior non-loadbearing wall or cut the bottom chord of the truss and fix it somehow? I know they say “never cut a truss”, but I’m really tempted. Trusses are 24″ o.c. Why can’t I weld up a little c-shaped deal out of steel tubing with flanges on the ends, bolt it in and then cut out a section of the 2 x 4? Seems like I could get more clearance to combustibles that way. The pipe requires 1″, but I always sleep better with more.
Thanks.
