Electrical Installation
(If Needed)
A knockout is provided in the left rear corner of the zero
clearance cabinet to install an electrical outlet (not supplied)
if desired. Be sure to ground the receptacle to the zero
clearance cabinet if installed. Figure 8.
Flue Rough-In Support Kit
Flue rough-in support #1-00-774283 installs in the zero
clearance cabinet and provides a flue stub mounting surface
which will be in the exact position of the stub when it is on
the insert mounting frame. Figure 9.
If you have not yet purchased the insert, order stub kit #
1-00-674040. This kit includes a 4” pipe stub, gasket and
mounting bolts. If you do have the insert, remove the flue
stub from the mounting frame. Install the exhaust stub onto
the support using the bolts and nuts from the support kit.
Install with bolts passing upward, through the support plate
and the flange nuts on the top. If installing the outside air kit,
install the stub from the kit onto the left side of the support.
It is not necessary to install the gaskets on the support
plate, however you will need them for final attachment.
Next, using 8 tek screws, install the rough in support into
the cabinet. You can now run your venting and air intake
and permanently attach them to their respective stubs. Be
sure to properly secure both, the venting and the outside air
pipe, so that they cannot move when you remove the rough-
in support. When all of the construction is completed, and
you are ready to install the insert, remove the support plate,
leaving the stubs in place. Install the insert mounting frame
and bolt the stub(s) and gasket(s) to the frame.
IMPORTANT! Install the stub gasket between the stub
and the mounting frame.
