3. The distance under a door or window to the edge of the flue pipe should be more than 22 inch from the
opening. The distance to the side of a door or window from the edge of the flue pipe should be more than 4
inch from opening.
4. 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.
5. 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.

From inside the room, insert the inner flue pipe through the hole. Make sure the arrow on the inner flue
pipe is pointing up. Secure the inner flue pipe to the wall with the three wood screws.

In the event that the wall is too thin, use the spacer as indicated in Fig. 8.
c. From outside, insert the outer flue pipe through the hole. Secure the outer flue pipe to the wall by turning it
clockwise. This locks the two halves together (See fig. 9).
IMPORTANT:
Make sure the arrow on the outer flue pipe flange is pointing up.
Make sure to secure the outer flue pipe well. (A-part shown in Fig. 9)
Check inside flue pipe for insulation and remore if any.
