3. For standard installation, use the template enclosed with the heater to position the hole for the flue pipe. Tack
or tape template to the wall at the desired position (See Fig. 4).
NOTE:
Heater should be installed on a sturdy floor that is level and flat.
4. Cut the hole for the flue pipe from inside the room. Use a 2-3/4 to 3” diameter hole saw attached to an electric
drill (See Fig. 5). The opening on the inside wall should be slightly higher than the outside opening
(approximately 1/4”) so that the flue pipe will slope slightly downward (approximately 2 degrees) after it is
installed (See Fig. 6). This will enable the draining of condensed moisture from the flue pipe to the outside and
prevent rain or snow entering from outside after installation.
NOTE:
After the cutting of the hole is completed, remove the template from the wall.
