Use and Care Manual

10 Rinnai Corporation EX17CT, EX22CT Manual
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 3 1/8 inch (80
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.
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.
2. Adjust the sleeve length
Measure wall thickness through previously drilled 3
1/8 inch (80 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.
• 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 heater.
• The termination cannot be vertical.
• This appliance can only be used with one of the
five types of Rinnai flue kits. The flue kits and their
dimensions are listed in the Specifications section.
• Refer to the Flue Terminal Clearances section.
