Installing the Flexible Pipe
Four springs are installed between the inside and outside pipe to ensure that an even air
space is provided. It is important that two springs be located at any bend in order to
prevent the pipes from touching. The length of pipe supplied is approximately 28"
(71cm). The pipe can be stretched to provide 1-2 additional inches. Bending the pipe
will cause the pipe to stretch.
It is important that the small exhaust pipe is fitted snug on the heater flue collar. Try
each end of the pipe and use the end that fits tighter. Once the small pipe is fitted snug
then insert the larger pipe ( this pipe does not have to fit as tight ) Pipes inserted into the
cap do not have to fit as snug.
We do not recommend you cut the pipe but the pipe can be cut with a fine hacksaw blade
to the required length. Twist the pipe to tighten the pipes flexibility, then tape the end of
the pipe and install a hose clamp on the side of the pipe that you are keeping. This is so
the clamp is left on the pipe and only removed after or during installing. Cut with fine
tooth hack saw blade then use a round file to remove the large burrs in the inside of the
pipe
.
Caution The flexible pipe can be easily damaged.
Additional 28" (70cm) or 10” (25.4cm) lengths of pipe are sold as an option (Part No. 19-
000 and 19-005). A coupling fitting is provided with the optional length.
Installing The Direct Vent Thru-Fitting and Cap
Step - 1
Measure, and cut or drill a 3" hole through the deck, ceiling or wall
where the exhaust cap will be located.
Step - 2
Make sure the sealing gasket is installed under the above deck-flange
before screwing down the fitting. Rotate the fitting to position the
pipe seam, inside the boat, so that it is not visible. Holding the deck
flange firmly in position secure with the 6 S/S screws supplied.
Step - 3
Attach the dress ring on the inside, underneath the fitting with the 4
S/S screws supplied. (Make sure that the opening lines up with the
underside of the thru-deck or the pipe will not fit correctly).
Step - 4
Install the flexible pipe on the heater. It is very important that the small
pipe fit tightly against the flue collar on the heater, the cap and any
other connections are not as important.
Step - 5
Make whatever bends are necessary in the flexible pipe and push into
the thru-fitting.
Step - 6
Attach the back mounting plate and secure the heater in position.
