18.7 Quick Connect Multi System Installation
• The Quick Connect Multi System allows the installation of two units together utilizing only the Quick Connect
Cord. Unit's MAX Btuh must be same in order to quick connect. e,g. When installing PV199DV (GHQ-
C3201WX-FF PB US), you must install UT199DV (GQ-C3260WX-FF PB US).
• The Quick Connect Cord is 6 ft. (2m) long. Install the units 3-18 in. (75-457 mm) apart from each other to
ensure the cord will be able to reach between the units. (See Typical Plumbing diagram).
(If the distance between the two units is too great, not only will the cord not be able to reach, but the water
temperature may also become unstable because of the difference in pipe length between the two units).

Leave enough clearance around the
plumbing to apply insulation. It will be
necessary to add bends to the piping to
ensure that this clearance is available.
The backflow preventer should be placed
upstream
of the cold water branch.
