Vent /Intake Terminations For Installation Of Multiple Direct Vent Furnaces; Oncentric Ent Ermination; Condensate Drain Lines & Drain Trap; General - Goodman GMS9 Installation Instructions Manual

nation Location for location restrictions. A 2 3/8 inch diameter wall
penetration is required for 2" diameter pipe while a 3 1/2 inch diam-
eter hole is required for 3" diameter pipe. To secure the pipe pass-
ing through the wall and prohibit damage to piping connections, a
coupling should be installed on either side of the wall and solvent
cemented to a pipe connecting the two couplings. The pipe length
should be the wall thickness plus the depth of the socket fittings to
be installed on the inside and outside of the wall. The wall penetra-
tion should be sealed with silicone caulking material.

In a basement installation, the pipes may be run between the joist
spaces. If the pipes must go below the joist and then up into the last
joist space to penetrate the header, two 45° elbows should be used
to reach the header rather than two 90° elbows.

If more than one direct vent furnace is to be installed vertically through
a common roof top, maintain the same minimum clearances be-
tween the exhaust vent and air intake terminations of adjacent units
as with the exhaust vent and air intake terminations of a single unit.
If more than one direct vent furnace is to be installed horizontally
through a common side wall, maintain the clearances as in the fol-
lowing figure. Always terminate all exhaust vent outlets at the same
elevation and always terminate all air intakes at the same elevation.

A condensing gas furnace achieves its high level of efficiency by
extracting almost all of the heat from the products of combustion
and cooling them to the point where condensation takes place. The
condensate which is generated must be piped to an appropriate
drain location.
In upright installations, the furnace's drain hoses may exit either the
right or left side of the furnace. NOTE: If the alternate vent/flue
outlet is utilized in an upright installation, the drain trap and drain
connections must be located on the same side as the alternate
vent/flue outlet.
In horizontal installations, the drain hoses will exit through the bot-
tom (down side) of the unit with the drain trap suspended beneath
the furnace. The field-supplied drain system must be in accordance
with all local codes and the instructions in the following sections.
