Thermostat Location; Combustion & Ventilation Air Requirements - Amana GUCA Installation Instructions Manual

The following vent testing procedure is reproduced from the
American National Standard/National Standard of Canada
for Gas-Fired Central Furnaces ANSI Z21.47-1998,
CSA-2.3-M98 Section 1.23.1.
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:
a. Seal any unused openings in the venting system;
b. Inspect the venting system for proper size and horizontal pitch,
as required by the National Fuel Gas Code, ANSI Z223.1 or the
CSA B149 Installation Codes and these instructions. Determine
that there is no blockage or restriction, leakage, corrosion and
other deficiencies which could cause an unsafe condition;
c. In so 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. Turn on clothes dryers and any appliance not con-
nected to the venting system. Turn on any exhaust fans, such as
range hoods and bathroom exhausts, so they shall operate at
maximum speed. Do not operate a summer exhaust fan. Close
fireplace dampers;
d. Follow the lighting instructions. Place the appliance being
inspected in operation. Adjust thermostat so appliance shall
operate continuously;
e. Test for draft hood equipped spillage at the draft hood relief
opening after 5 minutes of main burner operation. Use the flame
of a match or candle;
f. After it has been determined that each appliance connected to
the venting system properly vents when tested as outlined
above, return doors, windows, exhaust fans, fireplace dampers
and any other gas burning appliance to their previous conditions
of use;
g. If improper venting is observed during any of the above tests,
the common venting system must be corrected.
Corrections must be in accordance with the latest edition of
the National Fuel Gas Code NFPA 54/ANSI Z223.1 and/or
CSA B149 Installation Codes.
If resizing is required on any portion of the venting system,
use the appropriate table in Appendix G in the latest edition
of the National Fuel Gas Code ANSI Z223.1 and/or CSA B149
Installation Codes.

THERMOSTAT LOCATION

In an area having good air circulation, locate the thermostat
about five feet high on a vibration-free inside wall. Do not
install the thermostat where it may be influenced by any of
the following:
•
Drafts, or dead spots behind doors, in corners, or
under cabinets.
•
Hot or cold air from registers.
•
Radiant heat from the sun.
•
Light fixtures or other appliances.
•
Radiant heat from a fireplace.
•
Concealed hot or cold water pipes, or chimneys.
•
Unconditioned areas behind the thermostat, such
as an outside wall.

Consult the instructions packaged with the thermostat for
mounting instructions and further precautions.
V. Combustion & Ventilation
Air Requirements
WARNING
Possible death, personal injury or property
damage may occur if the furnace is not
provided with enough fresh air for proper
combustion and ventilation of flue gases.
Most homes require outside air to be
supplied to the furnace area.
Improved construction and additional insulation in buildings
have reduced heat loss by reducing air filtration and escape
around doors and windows. These changes have helped
in reducing heating/cooling costs but have created a prob-
lem supplying combustion and ventilation air for gas fired
and other fuel burning appliances. Appliances that pull air
out of the house (clothes dryers, exhaust fans, fireplaces,
etc.) increase the problem by starving appliances for air.
If this furnace is to be installed in the same space with other
gas appliances, such as a water heater, ensure there is an
adequate supply of combustion and ventilation air for the
other appliances. Refer to the latest edition of the National
Fuel Gas Code NFPA 54/ANSI Z223.1 (Section 5.3), or
CSA B149 Installation Codes (Sections 7.2, 7.3, or 7.4), or
applicable provisions of the local building codes for deter-
mining the combustion air requirements for the appliances.
Most homes will require outside air be supplied to the
furnace area by means of ventilation grilles or ducts con-
necting directly to the outdoors or spaces open to the
outdoors such as attics or crawl spaces.
