Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the wall
are packaged with the starter kit, and can be cut to suit if
necessary.
Guide the vent terminations 4” and 7” collard into their
respective vent pipes. Double check that the vent pipes
overlap the collars by ” (51 mm). Secure the termina-
tion to the wall with screws provided and caulk around
the wall plate to weatherproof. As an alternative to screw-
ing the termination directly to the wall, you may also use
expanding plugs or an approved exterior construction ad-
hesive. You may also attach the termination with screws
through the inner body into the 4” vent pipe, however for
this method, you must extend the 4” pipe approximately
6” (15 mm) beyond the outer face of the wall.
The 40” (1016 mm) flex vent is used for 90° off the
top of the unit then out the back wall.
Follow Step 1 and on Page .
Install the four (4) spacer springs on the 4” flex vent pipe.
When installing the spacer springs around the 4” pipe,
stretch the spring to approximately 15” (381 mm), wrap
the spring around the pipe and interlock the ends of the
spacer spring approximately ” (51 mm). Measure 6C\v”
(17 mm) from the end of the pipe. Place the next spring
5” (17 mm) from the previously installed spring. Place
the next spring 6” (15 mm) from the last spring. Finally
place the last spring 1” (305 mm) from the last spring
installed. Figure 29
Install the 4” (10 mm) flex vent pipe to the appliance col-
lar as described on Page 14. Secure the end with the first

pipe and secure the 7” collar as described on Page 14.
