DECK FITTING (CHARLIE NOBLE) INSTALL
Sealant or no sealant?
Heat and weather resistant sealant is recommended for
installs on textured or rough surfaces where the rubber
gasket makes incomplete contact with a roof’s surface
(fig 32) On smooth surfaces, a properly installed rubber
gasket alone can provide a sufficient seal.

The Deck Fitting
A light and effective stainless steel
replacement for a traditional charlie
noble, the Dickinson deck fittings are
extruded by hand using a process
called spinning. Each one is then finely
electro-polished as an added measure
to prevent stainless steel corrosion in
a marine environment.
Exit hole
The hole for the deck fitting must
provide a 1” clearance around the
deck fitting pipe. For a 3” chimney,
this means cutting a 5” hole.
The internal diameter of the rubber
gasket can be used to mark the
approximate hole size.
Mounting
The deck fitting attaches to chimney
pipe below and above the deck
surface while its bell also seals the
chimneys exit hole to prevent water
entry.
Install deck fitting first
The deck fitting should be installed prior to the construction of the
chimney. It will be far easier to attach the chimney to the deck fitting
this way. Once The deck fitting is installed, a tapered stainless sleeve
pulls down from the deck fitting to make the pipe easy to line up and
attach.
Tighten hardware evenly
Fasten down the deck fitting using the screws provided by slowly
tightening them in turn to evenly press the bottom of the deck flange
into the rubber gasket to create a seal. DO NOT pre-drill holes through
the rubber gasket! It may cause it to leak – screw the hardware right
through the gasket material.
