NOTE: Discharge static electricity accumulated in the body
before touching the unit. An electrostatic discharge can adversely
affect electrical components.
Use the following steps during furnace installations and servicing
to avoid damage to the integrated control module. By putting the
furnace, the control and the person at the same electrostatic
potential, these steps will help avoid exposing the integrated
control module to electrostatic discharge. This procedure is
applicable to both installed and non installed (ungrounded)
furnaces.
1. Disconnect all power to the furnace. Do not touch the
integrated control module or any wire connected to the
control prior to discharging your body's electrostatic charge
to ground.
WARNING
Possible property damage, personal injury or death due
Goodman 48
to fire, explosion, smoke, soot, condensation, electrical
shock or carbon monoxide may result from improper
installation, repair, operation or maintenance of this
product.
WARNING
Goodman 49
To prevent property damage, personal injury or death due
to fire, do not install the furnace in a mobile home, trailer
or recreational vehicle.
WARNING
Goodman 50
To prevent possible equipment damage, property damage,
personal injury or death, the following bullet points must
be observed when installing the unit.
Follow the instructions listed below when selecting a furnace
location. Refer also to the guidelines provided in "Combustion
and Ventilation Air Requirements."
Centrally locate the furnace with respect to the proposed or
existing air distribution system.
Check that the temperature of the return air entering the
furnace is between 55°F and 100°F (12.8ºC and 37.8ºC) when
the furnace is heating.
Provide provisions for venting combustion products outdoors
through a proper venting system. Special consideration
should be given to the vent/flue pipe routing and the
combustion air intake pipe when applicable. Refer to "Vent/
Flue Pipe and Combustion Air Pipe—Termination Locations"
for appropriate termination locations and to determine if the
piping system from the furnace to the termination can be
accomplished within the guidelines given.
NOTE: The length of flue and/or combustion air piping can be
a limiting factor in the location of the furnace.
Electrostatic Discharge (ESD)
2. Firmly touch a clean, unpainted, metal surface of the furnace
near the control. Any tools held in a person's hand during
grounding will be discharged also.
3. Service the integrated control module or connect wiring after
following the discharge process in Step 2.
NOTE: Do not recharge your body with static electricity by
moving or shuffling your feet or touching ungrounded
objects. Repeat Step 2 if you touch an ungrounded object.
4. Follow steps 1 through 3 before removing a new control from
its container or installing the control on a furnace. Return any
old or new controls to their containers before touching any
ungrounded object.
Location Requirements
Locate the furnace so that the condensate flows downward
to the drain.
NOTE: Do not locate the furnace or its condensate drainage
system in any area subject to below freezing temperatures
without the proper freeze protection. Refer to "Condensate
Drain Lines and Trap."
Check that adequate combustion air is available for the
furnace. Improper or insufficient combustion air can expose
building occupants to gas combustion products that could
include carbon monoxide. Refer to "Combustion and
Ventilation Air Requirements."
Set the furnace on a level floor to enable proper condensate
drainage. If the floor becomes wet or damp at times, place
the furnace above the floor on a concrete base sized
approximately 1¹⁄₂" (3.8 cm) larger than the base of the
furnace. Refer to "Horizontal Applications and
Considerations" for leveling of horizontal furnaces.
Check that the upflow or horizontal furnaces are not installed
directly on carpeting, or any other combustible material.
NOTE: The only combustible material allowed is wood.
A special accessory subbase must be used for the upright
counterflow unit installations over any combustible material
(including wood). Refer to subbase instructions for installation
details.
NOTE: A subbase will not be required if an air conditioning
coil is located beneath the furnace between the supply air
opening and the combustible floor.
Exposure to contaminated combustion air will result in safety
and performance-related problems.
NOTE: Do not install the furnace where the combustion air is
exposed to the following substances:
Chlorinated waxes or cleaners
Chlorine-based swimming pool chemicals
Water softening chemicals
Deicing salts or chemicals
Carbon tetrachloride
Halogen-type refrigerants
Cleaning solutions (such as perchloroethylene)
Printing inks
Paint removers
Varnishes
Hydrochloric acid
Cements and glues
Antistatic fabric softeners for clothes dryers
Masonry acid washing materials
