Alternate Vent/Flue Location - Amana GUCA Installation Instructions Manual

NOTE: Standard and alternate locations can be combined
(i.e., an installation may use the standard combustion air
intake location but use the alternate vent/flue location or
vice versa), if needed.
CAUTION
Edges of sheet metal holes may be sharp.
Use gloves as a precaution when removing
hole plugs.

Alternate Vent/Flue Location

The alternate vent/flue location is the large hole directly in
line with the induced draft blower outlet. To use the
alternate vent/flue location refer to the following steps, the
"Vent/Flue Pipe Cuts" figure, and the "Alternate Vent/Flue
Location" figure.
NOTE: Counterflow instructions follow the upflow instruc-
tions.
1. Remove and save the four screws securing the vent/
flue coupling to the furnace top panel.
Counterflow units.
Remove and save the four screws securing the vent/
flue coupling to the furnace basepan. Also remove the
three screws securing the furnace's internal vent/flue
piping to the blower deck.
2. Upflow and Counterflow units.
Loosen the worm gear hose clamps on the rubber
elbow and detach it from both the induced draft blower
and the vent/flue pipe.
3. Upflow and Counterflow units.
Remove the vent/flue pipe from the furnace.
4. Cut the vent/ flue pipe at the elbow nearest the coupling
end of the pipe (see " Vent/Flue Pipe Cuts" figure). The
section of pipe attached to the coupling will reach
through the side panel to the induced draft blower.
Discard unused pipe and elbows.
Counterflow units.
Cut the vent/flue pipe 3.718 inches from the blower
deck coupling (see "Vent/Flue Pipe Cuts" figure). Save
vent/flue pipe attached to blower deck coupling for use
in the alternate location. Discard remaining pipe and
elbows.

5. Remove plastic plug from alternate vent/flue location.
Relocate and install plug in standard vent/flue location
(top cover).
Counterflow units.
Remove plastic plug from alternate vent/flue location.
Relocate and install plug in standard vent/flue location
(basepan). Plug remaining hole in blower deck with
plastic plug included in the drain kit bag.
6. Upflow and Counterflow units.
Insert cut section of vent/flue pipe and coupling into
alternate vent/flue location. Using a rubber coupling
and worm gear hose clamps from the drain kit bag,
attach the vent/flue pipe and coupling to the induced
draft blower. Secure the coupling to the cabinet using
the screws removed in step 1 or with field-supplied 3/8"
#8 self drilling screws.
WARNING
The rubber elbow is not designed to support
a load. When the rubber elbow is mounted
externally to the furnace cabinet, extreme
care must be taken to adequately support
field-supplied vent/flue piping. As damage
can result in leaks causing bodily injury or
death due to exposure to flue gases,
including carbon monoxide.
7. Upflow and Counterflow units.
For upright installations, externally mount the rubber
elbow to the vent/flue coupling using a worm gear hose
clamp. Secure field supplied vent/flue piping to the
rubber elbow using a worm gear hose clamp. NOTE:
Use of the alternate vent/flue location for upright instal-
lations, requires the drain trap be installed on the same
side of the unit as the flue pipe.
8. Upflow and Counterflow units.
For horizontal installations, externally secure the
field-supplied vent/flue pipe directly to the vent/flue
coupling using a PVC or ABS coupling or elbow.
