Amana GUIA Series Service Instructions Manual page 52

PRODUCT DESIGN
Horizontal terminations should be as shown in the follow-
ing figure. Refer to Vent/Flue Pipe and Combustion Pipe -
Termination Location section in this manual or the installa-
tion instructions for location restrictions. A 2 3/8" diameter
wall penetration is required for 2" diameter pipe while a
3 1/2" diameter hole is required for 3" diameter pipe. To
secure the pipe passing through the wall and prohibit dam-
age 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 pen-
etration 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.
Vent/Intake Terminations for Installation of Multiple
Direct Vent Furnaces (90% Furnaces Only)
If more than one direct vent furnace is to be installed verti-
cally through a common roof top, maintain the same mini-
mum clearances between the exhaust vent and air intake
terminations of adjacent units as with the exhaust vent and
air intake terminations of a single unit.
