Furnace Suspension; Front Cover Pressure Switch Tubel; Drain Trap And Lines; Horizontal Furnace Leveling - Goodman xMEC96 Series User Manual

F S
URNACE USPENSION
If suspending the furnace from rafters or joists, use 3/8" threaded
rod and 2"x2"x1/8" angle iron as shown in the following diagram.
The length of rod will depend on the application and the clearances
necessary.
If the furnace is installed in a crawl space it must be suspended
from the floor joist or supported by a concrete pad. Never install
the furnace on the ground or allow it to be exposed to water.

RONT OVER RESSURE
When an upflow model is installed horizontally with left side
down, the front cover pressure switch tube must be relocated
to the lower port of the collector box cover.
1. Remove tube from front cover pressure switch and collector
box cover.
2. Remove rubber plug from bottom collector box port and install on top collector box port.
3. Locate 24" x 1/4" tube in parts bag.
4. Install one end on front cover pressure switch.
5. Route tube to lower port on collector box cover and cut off excess tubing.

RAIN RAP AND INES
In horizontal applications the condensate drain trap is secured to the furnace side panel, suspending it below the furnace. A minimum
clearance of 5.5" 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 Condensate Drain Trap and Lines for further details. If the drain trap and
drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to prevent condensate from
freezing.

ORIZONTAL URNACE
Leveling ensures proper condensate drainage from the heat exchanger and induced draft blower. For proper flue pipe drainage, the
furnace must be level lengthwise from end to end. The furnace should have a slight tilt from back to front with the access doors
downhill from the back panel approximately 1/2 to 3/4 inches. The slight tilt allows the heat exchanger condensate, generated in
the recuperator coil, to flow forward to the recuperator coil front cover.

LTERNATE LECTRICAL AND
This furnace has provisions allowing for electrical and gas line connections through either side panel. In horizontal applications the
connections can be made either through the "top" or "bottom" of the furnace.
D P
RAIN AN
A drain pan must be provided if the furnace is installed above a conditioned area. The drain pan must cover the entire area under the
furnace (and air conditioning coil if applicable).

REEZE ROTECTION
Refer to Horizontal Applications and Conditions - Drain Trap and
Lines.

ROPANE AS IGH
This furnace is shipped from the factory configured for natural gas
at standard altitude. Propane gas installations require an orifice
and spring change to compensate for the energy content differ-
ence between natural and propane gas.
High altitude installations may require both a pressure switch and
an orifice/spring change. These changes are necessary to compensate for the natural reduction in the density of both the gas fuel and
the combustion air at higher altitude.
