Amana xMVM97 series Installation Instructions Manual page 8

• Counterflow Installation over a combustible floor. If
installation over a combustible floor becomes necessary,
use an accessory subbase (see Specification Sheet
applicable for your model for details.) A special accessory
subbase must be used for upright counterflow unit
installations over any combustible material including
wood. Refer to subbase instructions for installation
details. Follow the instructions with the subbase for
proper installation. Do not install the furnace directly
on carpeting, tile, or other combustible material other
than wood flooring. (NOTE: The subbase will not be
required if an air conditioning coil is installed between
the supply air opening on the furnace and the floor.)

C = If placed on combustible floor, floor MUST be wood only.
NOTES:
• For servicing or cleaning, a 24" front clearance is required.
• Unit connections (electrical, flue and drain) may necessitate
greater clearances than the minimum clearances listed above.
• In all cases, accessibility clearance must take precedence
over clearances from the enclosure where accessibility
clearances are greater.

C = If placed on combustible floor, floor MUST be wood only.
NC = For installation on non-combustible floors only. A combustible subbase
must be used for installations on combustible flooring.
NOTES:
• For servicing or cleaning, a 24" front clearance is required.
• Unit connections (electrical, flue and drain) may necessitate
greater clearances than the minimum clearances listed above.
• In all cases, accessibility clearance must take precedence
over clearances from the enclosure where accessibility
clearances are greater.
Installations must adhere to the clearances to combustible mate-
rials to which this furnace has been design certified. The mini-
mum clearance information for this furnace is provided on the
unit's clearance label. These clearances must be permanently
maintained. Clearances must also accommodate an installation's
gas, electrical, and drain trap and drain line connections.
NOTE: In addition to the required clearances to combustible
materials, a minimum of 24 inches service clearance must be
available in front of the unit.

NOTE: When an existing furnace is removed from a venting
system serving other appliances, the venting system may be too
large to properly vent the remaining attached appliances.
The following vent testing procedure is reproduced from the
American National Standard/National Standard of Canada
FLOOR
for Gas-Fired Central Furnaces ANSI Z21.4, CSA-2.3 lat-
C
est edition Section 1.23.1.
C
The following steps shall be followed with each appliance
connected to the venting system placed in operation, while
any other appliances connected to the venting system are
not in operation:
1. Seal any unused openings in the venting system;
2. Inspect the venting system for proper size and horizontal
pitch, as required by the National Fuel Gas Code, ANSI
Z223.1 or the Natural Gas and Propane Installation Code,
CSA B149.1-05 and these instructions. Determine that
there is no blockage or restriction, leakage, corrosion
TOP
and other deficiencies which could cause an unsafe con-

dition.
6"
3. As far as practical, close all building doors and windows
and all doors between the space in which the appliance(s)
connected to the venting system are located and other
spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not connected
to the venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, so they shall oper-
ate at maximum speed. Do not operate a summer ex-
haust fan.
6. Follow the lighting instructions. Place the appliance be-
ing inspected in operation. Adjust thermostat so appli-
ance shall operate continuously.
7. Test for spillage from draft hood appliances at the draft
hood relief opening after 5 minutes of main burner op-
eration. Use the flame of a match or candle.
8. If improper venting is observed during any of the above
tests, the venting system must be corrected in accor-
dance with the National Fuel Gas Code ANSI Z223.1/NFPA
54 and/or National Gas and Propane Installation Code
CSA B149.1-05.
