How close to a fireplace can a register duct boot be placed?
I am doing a remodel in the living room and the existing register is almost centered in front of the fireplace and 4'7" (center of register to front of fireplace). I see that because of a 16" x 4" load bearing beam the vent could not be moved further (right) away from the fireplace during the original construction - although there are 6 additional feet of space to the right of the load bearing beam.
In my remodel I was looking to move the register 1 foot closer to the fireplace - and I cannot go 1 foot further away because of sewer plumbing in that space. I need to get access to the space to put some 2"x8" braces for a shower above this space.
For HVAC experts out there, Any issues with moving the register closer to the fireplace?
