Exterior Masonry Chimneys; Ategoryi Furnaces Only ) - Amana GDH8 Installation Instructions Manual

The minimum vent diameter for the Category I venting system
is as shown:
MODEL
UPFLOW
40 4 Inch
60 4 Inch
80 4 Inch
100 5 Inch
120 5 Inch
140 5 Inch
Under some conditions, larger vents than those shown above
may be required or allowed. When an existing furnace is re-
moved from a venting system serving other appliances, the
venting system may be too large to properly vent the remaining
attached appliances.
Upflow or Horizontal units are shipped with the induced draft
blower discharging from the top of the furnace. ("Top" is as
viewed for an upflow installation.) The induced draft blower can
be rotated 90 degrees with the (0270F01119) chimney transi-
tion bottom kit for Category I venting. For horizontal installa-
tions, a four inch single wall pipe can be used to extend the
induced draft blower outlet 1/2" beyond the furnace cabinet.
THIS PRODUCT IS NOT DESIGNED FOR COUNTERCLOCK-
WISE INDUCED DRAFT BLOWER ROTATION.
Vent the furnace in accordance with the National Fuel Gas
Code NFPA 54/ANSI Z223.1 - latest edition. In Canada, vent
the furnace in accordance with the National Standard of Canada,
CAN/CSA B149.1 and CAN/CSA B149.2 - latest editions and
amendments.
Venting - Furnace Installed in Horizontal Position
THIS FURNACE IS NOT DESIGN CERTIFIED TO BE HORI-
ZONTALLY VENTED THROUGH AN EXTERIOR SIDE WALL.
The following describes an optional venting procedure when the
furnace is installed in the horizontal left discharge position.
To rotate the induced draft blower clockwise, you will need to
purchase one (0270F01119) chimney transition bottom kit.
1. Disconnect electrical power from the furnace.
2. Disconnect the induced draft blower power leads, flue
pipe, and pressure switch tubing.
3. Remove the round cutout from the right side of the wrapper.
4. Remove and save the four screws that fasten the induced
draft blower to the flue collector box.
5. Remove and save the three screws that hold the chimney
assembly to the induced draft blower.
6. Remove and save the four screws that fasten the chimney
top to the chimney bottom.
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
discharging from the top of the furnace. ("Top" as viewed for a
counterflow installation.)
Vent the furnace in accordance with the National Fuel Gas
Code NFPA54/ANSI Z223.1-latest edition. In Canada, vent the
furnace in accordance with the national standard of Canada,
CAN/CSA B149.1 and CAN/CSA B149.2- latest editions and
amendments.

XTERIOR ASONRY
An exterior masonry chimney is defined as a "Masonry" chim-
ney 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. Re-
searchers have discovered 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.
