Deck Fitting
To install the thru deck fitting, a hole must be cut in your deck. Depending on
the diameter of the chimney stack will depend on the size hole that needs to be
cut. There should be a 1” clearance all around the chimney pipe. For example, a
3” diameter exhaust pipe would require a 5” hole drilled in the deck. Once a
hole is cut, you can line the raw hole with epoxy, caulking or a metal liner to
finish it off. Just ensure there is a 1” air gap between the side of the hole and the
chimney pipe.
The thru-deck fitting includes a stainless steel dress ring for the interior of
the cabin and a neoprene rubber gasket to better seal the fitting on the deck
side. Depending on the contour or the angle of the cabin top, you may need
to make a hardwood spacer block. One surface of the block would be a level
plane to mate to the deck cap. The other would match the angle or contour of
the cabin top. A hole through the center of the block would also be 2 inches
greater then the diameter of the flue pipe.
Exhaust Cap
The DP round or H style exhaust caps are most recommended. The exhaust
cap will fit over the crimp on the deck fitting or flue pipe. The location of
the exhaust cap above deck must be clear of any immediate obstruction that
may cause unusual air movement or turbulence. CAUTION: The Exhaust
Cap gets hot when the stove is operating.
