Well I didn’t get any hits on my first post so hoping someone can help me out on this issue.
We have poured a new footing and framed in chase which is wider at the bottom with a narrower up through the roof. See Pic - outside chase. This is basically what our old masonry chimney looked like before it was torn down (was going to be a full rebuild). We wanted to avoid the “elevator shaft” look on our small house and plan to clad it in cultured stone.
I am confused on clearance requirements from the top of the fireplace on the inside of the chase. All manuals for gas fireplaces list the dimensions to the ceiling which I interpret as in front of the fireplace. Some note the distance to the ceiling of the enclosure but most of them are ambivalent. I know you cannot put anything below the standoffs. Because of the way my chase is constructed we have two beams supporting the upper portion (narrower part) of the chase which sit above the unit which are at the same level as the rough opening height (header). See pic - inside chase. You can also see the plumb bob for help determining my vent placement and clearances.
Even the building inspector I chatted with agreed that some models don’t really make it clear and that if there was no minimum dimension for framed enclosure ceiling height specifically he would go off dimensions to combustibles (rough opening height). I’m good on all my other clearance dimensions. The 2 clearance pics are from Regency P33CE install manual. Clearance 1 pic outlines dimension "C" clearance to ceiling from top of unit to ceiling as 30 inches. Clearance 2 pic shows dimension "M" shows framed chase ceiling as 36" for rigid vent pipe or 32" for flex pipe measured from base of unit.
Have any of you dealt with this kind of installation before? I'm sure I'm over thinking this but the ceiling height to me means in the room in front of fireplace and enclosure ceiling height to me means inside the chase. Any comments would be appreciated. Thanks, Karen
