Installation Positions; Horizontal Applications & Considerations; General; Drain Trap And Lines - Goodman GKS9 Installation Instructions Manual

5. When directly communicating with the outdoors, the single open-
ing shall have a minimum free area of 1 square inch per 3,000
BTU per hour of total input rating of all equipment in the enclo-
sure.
5.3.4 Specially Engineered Installations:
The requirements of 5.3.3 shall not necessarily govern when special
engineering, approved by the authority having jurisdiction, provides an
adequate supply of air for combustion, ventilation, and dilution of flue
gases.
5.3.5 Louvers and Grilles:
In calculating free area in 5.3.3, consideration shall be given to the
blocking effect of louvers, grilles or screens protecting openings. Screens
used shall not be smaller than 1/4 inch mesh. If the area through a
design of louver or grille is known, it should be used in calculating the
size of opening required to provide the free area specified. If the design
and free area is not known, it may be assumed that wood louvers will
have 20-25 percent free area and metal louvers and grilles will have 60-
75 percent free area. Louvers and grilles shall be fixed in the open
position or interlocked with the equipment so that they are opened au-
tomatically during equipment operation.
5.3.6 Special Conditions Created by Mechanical Exhausting or Fire-
places:
Operation of exhaust fans, ventilation systems, clothes dryers, or fire-
places may create conditions requiring special attention to avoid unsat-
isfactory operation of installed gas utilization equipment. Air from In-
side Building. See 5.3.3-a.

NOTE: This furnace is shipped from the factory as a Dedicated
Upflow. A "Blocked Drain Kit" is available and MUST BE USED if the
furnace is installed Horizontal Left or Horizontal Right. Check the
Serial/ Rating Plate on the furnace for the Kit P/N.
This furnace may be installed in an upright position or horizontal on
either the left or right side panel. Do not install this furnace on its
back. For upright upflow furnaces, return air ductwork may be at-
tached to the side panel(s) and/or basepan. For horizontal upflow
furnaces, return air ductwork must be attached to the basepan.
NOTE: Ductwork must never be attached to the back of the fur-
nace. Contact your distributor for proper airflow requirements and
number of required ductwork connections. Refer to "Recommended
Installation Positions" figure for appropriate installation positions,
ductwork connections, and resulting airflow arrangements.

ENERAL
Horizontal applications, in particular, may dictate many of the
installation's specifics such as airflow direction, ductwork connec-
tions, flue and combustion air pipe connections, etc. The basic ap-
plication of this furnace as a horizontal furnace differs only slightly
from an upright installation. When installing a furnace horizontally,
additional consideration must be given to the following:

RAIN RAP AND
In horizontal applications the condensate drain trap is secured to
the furnace side panel, suspending it below the furnace. A mini-
mum clearance of 4 3/4 inches below the furnace must be provided
for the drain trap. Additionally, the appropriate downward piping
slope must be maintained from the drain trap to the drain location.
Refer to Section X, Condensate Drain Trap and Lines for further
details. If the drain trap and drain line will be exposed to tempera-
tures near or below freezing, adequate measures must be taken to
prevent condensate from freezing.

EVELING
Leveling ensures proper condensate drainage from the heat ex-
changer and induced draft blower. For proper flue pipe drainage,
the furnace must be level lengthwise from end to end. The furnace
should also be level from back to front or have a slight tilt with the
access doors downhill (approximately 3/4 inches) from the back
panel. The slight tilt allows the heat exchanger condensate, gener-
ated in the recuperator coil, to flow forward to the recuperator coil
front cover.

In horizontal installations provisions for alternate flue piping are avail-
able for upflow furnaces with left discharge . This configuration al-
lows the flue piping to be run vertically through the furnace. Refer to
the "Recommended Installation Positions" figure for further detail.
The standard piping connections may also be used in these posi-
tions. Refer to Section IX, Vent/Flue Pipe and Combustion Air Pipe
for details concerning the conversion to the alternate vent/flue con-
nections.
