Combustion and Ventilation Air
WARNING
Possible death, personal injury or prop-
ertydamagemayoccurifthefurnaceand
otherfuel-burningappliancesarenotpro-
vided with enough fresh air for proper
combustionandventilationoffluegases.
Most homes require outside air to be
supplied into the furnace area.
Improved construction and additional insulation in build-
ings has reduced the heat loss, making these buildings
muchtighterarounddoors andwindowsso air infiltration
isminimal.Thiscreatesaproblemsupplyingcombustion
and ventilation air for gas fired and other fuel burning
appliances.Useofappliancespullingairoutofthehouse
(clothes dryers, exhaust fans, fireplaces, etc.) increases
this problem causing appliances to starve for air.
This furnace must use indoor air for combustion. It
cannot be installed as a direct vent (i.e., sealed com-
bustion) furnace. The burner box is present only to help
reduce sound transmission from the burners to the
occupied space.
Air Requirements
Most homes will require outside air supplied to the
furnace area by means of ventilation grilles or ducts
connectingdirectlytotheoutdoorsorspacesopen to the
outdoors such as attics or crawl spaces. The following
informationonairforcombustionandventilationisrepro-
duced from the National Fuel Gas Code NFPA54/ANSI
Z223.1 Section 5.3.

5.3.1 General:
(a) The provisions of 5.3 apply to gas utilization equip-
ment installed in buildings and which require air for
combustion, ventilation and dilution of flue gases from
within the building. They do not apply to (1) direct vent
equipment which is constructed and installed so that all
air combustion is obtained from the outside atmosphere
and all flue gases are discharged to the outside atmo-
sphere, or (2) enclosed furnaces which incorporate an
integral total enclosure and use only outside air for
combustion and dilution of flue gases.
(b)Equipment shallbe installedin a location in which the
facilities for ventilation permit satisfactory combustion of

IV. Category IVenting (Vertical
Venting)
WARNING
To prevent possible death or personal
injury due to asphyxiation, Amana Non-
Condensing Gas Fired Warm Air Fur-
naces must be Category I vented. Do not
vent any of these furnaces using Cat-
egory III venting.
Category I Venting (vent at a non-positive pressure)
doesnothavetobegas-tight. WhenventedasCategory
I, this furnace is considered a fan-assisted appliance,
which has an induced draft blower to draw products of
combustion through the heat exchanger, and under
some conditions may be vented in common with natural
draft appliance (such as most water heaters).
All installations must be vented in accordance with Na-
tional Fuel Gas Code, NFPA 54 / ANSI Z223.1 - latest
edition. In Canada, the furnaces must be vented in
accordancewiththeNationalStandardofCanada, CAN/
CGA B149.1 and .2 - latest editions and amendments.
For any Category I installation, the vertical height of the
venting system will be at least as great as the horizontal
length of the venting system.
WARNING
To prevent possible death or personal
injuryduetoasphyxiation,commonvent-
ing with other manufacturer’s induced
draft appliances is not allowed.
Common venting with specific Amana Category I 80%
furnacesisallowedwiththeadditionofacommonventkit

Check 1 - Proper chimney termination.
A masonry chimney used as a vent for gas fired equip-
ment must extend at least three feet above the highest
point where it passes through the roof. It must extend at
least two feet higher than any portion of a building within
a horizontal distance of 10 feet. In addition, the chimney
must terminate at least 3 feet above any forced air inlet
located within 10 feet. The chimney must extend at least
five feet above the highest connected equipment draft
hood outlet or flue collar.
If the chimney does not meet these termination require-
ments, but all other requirements in the checklist can be
met, it may be possible for a mason to extend the
chimney. If this will not be practical, see Fix 1, page 12.
