GE® Indoor Tankless Water Heater
Dimensions and Installation Information (in inches)
Locating the Unit
•
Install the unit in a location central to where hot water is used.
• Sizing guide is based on the following:
• In homes with large hot water demand consider locating the
tankless hot water heaters in different parts of the home near
the point of use for optimal performance (you may cascade
up to 5 total units).
• If installing indoors, consider installing on an exterior wall to
minimize vent length.
• The compact design allows several location options: closet,
garage, basement laundry/mud room; even under stairs.

Dimensions and Installation Information (in inches)
Installation:
Planning for plumbing
(shown with optional pipe cover)
The center of the pipes can be
placed anywhere within the
shaded area.
The center of the pipes is
recommended to be protruding
only within 6" of the mounting
wall. Other specific installations
may be different.
Be sure that the minimum
elevation of the bottom of
the unit is 18" to meet the 36"
recommended clearance for the
exhaust.
Note: It is recommended to install
the bottom of the unit at least
18" off the ground to minimize
blockage from debris and provide
room for the optional Pipe Cover
Accessory, AGTPCM.

Additional clearances—vent terminal
These clearances are applicable to both
concentric termination and non-concentric vent
exhaust terminations.
• Avoid termination locations near a dryer vent.
• Avoid termination locations near
commercial cooking exhaust
Vent Length Calculations
Maximum System performance is achieved at a vent length of 21
equivalent feet or less. The system is capable of 41 equivalent feet length if
required, but this reduces system performance. For vent length calculations,
a 90˚ elbow counts as 6 feet and a 45˚ elbow counts as 3 feet—see the
chart below.
Concentric Vent Piece Equivalent Length
Straight 1 ft (per foot length)
90˚ elbow 6 ft each
45˚ elbow 3 ft each
Total vent length = straight ft + 90˚ elbows x 6 ft + 45˚ elbow x 3ft
Note: Vent dimensions = up to 5 3/4 inches. Please read vent supplier's
installation manual for specific dimensions.
