4.4 Installation Steps

4.4. 1 Drill the Flue Hole
Ensure that there are no gas or water lines, or
electrical circuits in the wall location where the
flue hole is to be drilled. Drill the flue hole using
a Ø3 1/8 inch (Ø80 mm) drill. The center of the
hole must be located exactly at the specified
point.
See diagram. For weatherboard walls, drill
through the center of the weatherboard from
the outside first and then through the
plasterboard. A template is provided.
For installation without using extension kits, the
configuration of the flue manifold, air intake
hose, and exhaust slide pipe should be as
shown when installation is completed. The 60
degree arc shows where the flue manifold can
be located.
NOTE
Use a template (included) to determine
allowable location of the flue hole.
Figure 8
4.4.2 Install the Flue Manifold
Guidelines:

The flue manifold must exhaust to the
outside. Do not exhaust into other rooms.

The flue manifold is not designed to be
positioned under floors or below the
furnace.

The termination cannot be vertical.

This furnace can only be used with one of
the five types of Rinnai flue kits. The flue
kits and their dimensions are listed in
section "4.2.1 Items Included."

Refer to "Flue Terminal Clearances" in
section "4.3.2 Clearances."

Instructions:
1. Disassemble the flue manifold
The flue consists of 3 parts:
 sleeve
 inside connection
 outside terminal
Disassemble the flue manifold by first pulling
out the inside connection. To remove the outer
terminal pull and release the two internal ties
and then pull out the outer terminal.
Clearance to combustibles for the sleeve and
flanges is zero inches.
Inside Connection

2. Adjust the sleeve length
Measure wall thickness through previously
drilled Ø3 1/8 inch (Ø80 mm) hole.
The end of the sleeve should protrude 3/16 -
3/8 inch (5-10 mm) from the outside wall.
The sleeve is threaded for adjustment.
Adjust the sleeve length to wall thickness
plus 3/16 - 3/8 inch (5-10 mm).
NOTE: Do not extend beyond the red line.
For other than the "S" type flue manifold, if a
shorter length is necessary an extension can
be removed. Cut the outer plastic laminate
(with a utility knife or similar) and remove the
extension. The metal should not be cut.
