Exterior Masonry Chimneys (Category I Furnaces Only); Checklist Summary - Amana M8 Installation Instructions Manual

7. Remove the chimney transition bottom from the transition
bottom kit.
8. Install the chimney top with the four screws retained from
step 6 onto the new chimney transition bottom from the
transition bottom kit.
9. Remove the induced draft blower and install the new
chimney assembly to it using the three screws retained
from step 5.
10. Rotate the induced draft blower 90 degrees to the right,
feed the flue pipe through the round cutout from the outside
of the wrapper, and fit onto the chimney top assembly.
Secure the pipe to the chimney top from the front, top, and
bottom using (3) screws and rotating the induced draft
blower to properly orient the assembly. NOTE: If the pipe
section is less than 18", then attach it directly to the chimney
top on 3 sides and feed it through the round cutout from the
inside of the wrapper.
11. Reattach the induced draft blower using the (4) screws
retained from step 3. Ensure the gasket located between
the induced draft blower and collector box is rotated
accordingly.
12. Reconnect the induced draft blower power leads. NOTE: If
the wires are not long enough, pull extra wire from the wire
bundle in the blower compartment.
13. Reconnect the remaining flue pipe, and the pressure switch
tubing. Ensure that all wires and the pressure switch tubing
is at least one inch from the flue pipe, or any other hot
surface.
14. Restore power to furnace.
NOTE: In a horizontal installation the air conditioning coil must
be adequately supported by proper brackets and supports.
Inadequate coil support can result in furnace cabinet distortion
and air leakage.
Counterflow units are shipped with the induced draft blower dis-
charging from the top of the furnace. ("Top" as viewed for a coun-
terflow installation.)
Vent the furnace in accordance with the National Fuel Gas Code
NFPA54/ANSI Z223.1-latest edition.

XTERIOR ASONRY HIMNEYS
An exterior masonry chimney is defined as a "Masonry" chimney
exposed to the outdoors on one or more sides below the roof line."
The ability to use a clay lined masonry chimney depends on a
parameter not associated with interior chimneys. This variable is
the geographic location of the installation. Researchers have dis-
covered that the winter design temperatures have a direct impact
on the suitability of this type of venting. In most situations, the
existing masonry chimneys will require a properly sized metallic
liner.

HECKLIST UMMARY
This checklist serves as a summary of the items to be checked
before venting an 80+ furnace into a masonry chimney. In addi-
tion, we recommend that a qualified serviceman use this checklist
to perform a yearly inspection of the furnace venting system.
This checklist is only a summary. For detailed information on
