Thermostat Location; Combustion & Ventilation Air; Requirements - Goodman *MVM96 Installation Instructions Manual

3. As far as practical, close all building doors and win-
dows and all doors between the space in which the
appliance(s) connected to the venting system are lo-
cated 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
operate at maximum speed. Do not operate a summer
exhaust fan.
6. Follow the lighting instructions. Place the appliance being
inspected in operation. Adjust thermostat so appliance
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.
9. After it has been determined that each appliance con-
nected 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.
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 B149.1-05
Installation Codes.

HERMOSTAT OCATION
The thermostat should be placed approximately five feet from the
floor on a vibration-free, inside wall in an area having good air
circulation. Do not install the thermostat where it may be influ-
enced 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.

SUFFICIENT FRESH AIR FOR
FLUE GASES MUST BE SUPPLIED
SUPPLIED INTO THE FURNACE
Improved construction and additional insulation in buildings have
reduced heat loss by reducing air infiltration and escape around
doors and windows. These changes have helped in reducing
heating/cooling costs but have created a problem supplying com-
bustion 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 of air.
House depressurization can cause back drafting or improper com-
bustion of gas-fired appliances, thereby exposing building occu-
pants to gas combustion products that could include carbon mon-
oxide.
When the furnace is installed as a direct vent (2-pipe system)
furnace, no special provisions for air for combustion are re-
quired. However, 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 or CAN/CSA B149 Instal-
lation Codes or applicable provisions of the local building codes
for determining the combustion air requirements for the appli-
ances.
Most homes will require outside air be supplied to the furnace
area by means of ventilation grilles or ducts connecting directly
to the outdoors or spaces open to the outdoors such as attics or
crawl spaces.
The following information on air for combustion and ventilation is
reproduced from the National Fuel Gas Code NFPA 54/ANSI
Z223.1 Section 9.3.
9.3* Air for Combustion and Ventilation.
9.3.1 General.
9.3.1.1 Air for combustion, ventilation, and dilution of flue gases for
appliances installed in buildings shall be obtained by application of one of
the methods covered in 9.3.2 through 9.3.6. Where the requirements of
9.3.2 are not met, outdoor air shall be introduced in accordance with meth-
ods covered in 9.3.3 through 9.3.6.
Exception No. 1: This provision shall not apply to direct vent appliances.
9.3.1.2 Appliances of other than natural draft design and other than Cat-
egory 1 vented appliances shall be provided with combustion, ventilation,
and dilution air in accordance with the appliance manufacturer's instruc-
tions.
9.3.1.3 Appliances shall be located so as not to interfere with proper
circulation of combustion, ventilation, and dilution air.
