Venting; Blower Assembly Installation - Rheem GG50T06PVT Use And Care Manual

Installing the water heater.
The water heater must be installed with the factory supplied blower assembly in place.
DANGER: Failure to
install the blower
assembly and properly
vent the water heater to
the outdoors as outlined
in the Venting section of
this manual will result in
unsafe operation of the
water heater causing
bodily injury, explosion,
fire or death.
To avoid the risk of
fire, explosion, or
asphyxiation from
carbon monoxide, NEVER
operate the water heater
unless it is properly
vented and has adequate
air supply for proper
operation as outlined in
the Venting section of
this manual.
The vent pipe must
overlap a minimum of ½"
on each connection. It
is important that the vent
pipe engages fully into
any pipe fitting and be
kept in that position until
the adhesive has fully
cured. DO NOT drill
or punch holes in the
plastic pipe or fittings.
NOTICE: This unit is
equipped with a Flammable
Vapor Sensor. Do not apply
power until enough time
has passed to allow the
vapors from the primer and
cement to dissipate.

Venting

The water heater must be vented to
the outdoors as described in these
instructions. DO NOT connect this water
heater to an existing vent or chimney - it
must be vented separately from all other
appliances.
NOTICE: This unit can be vented using only
the following recommended pipe material.
Use only 2- or 3-inch diameter pipe.
PVC (Schedule 40, ASTM D1785)
CPVC (Schedule 40, ASTM F441)
ABS (Schedule 40, ASTM D2661)
ABS (Schedule 40 DWV, Cellular Core,
ASTM F891)
The fittings, other than the TERMINATION,
should be equivalent to the following:
PVC (Schedule 40 DWV, ASTM D2665)
CPVC (Schedule 40 DWV, ASTM F438)
ABS (Schedule 40 DWV, ASTM D2661)
The unit may be vented horizontally
through a wall or vertically through the
roof.
Pipe runs must be adequately supported
along both vertical and horizontal runs.
Maximum unsupported span is
recommended to be no more than 6 feet.
It is imperative that the first hanger be
located on the horizontal run immediately
adjacent to the first 90-degree elbow
from the vertical rise.
Support method used should isolate
the vent pipe from floor joists or other
structural members to help prevent the
transmission of noise and vibration.

Blower Assembly Installation

(If not factory installed)
Rubber
Connect blower assembly with the electrical connector. Attach
Coupling
Blower Assembly to top pan using the six (6) screws provided
(See diagram to the left). Install rubber coupling (supplied in
the box with water heater) on blower housing and secure it.

Baffle
NOTICE: The Blower Assembly is Btuh input specific and
is not certified for use on any other Btuh input model.
Do not support, pin or otherwise secure
the venting system in a way that
restricts the normal thermal expansion
and contraction of the chosen venting
material.
If the water heater is being installed as a
replacement for an existing power vented
water heater, a thorough inspection of
the existing venting system must be
performed prior to any installation work.
Verify that the correct materials as
detailed above have been used, and that
the minimum or maximum vent length
and terminal locations as detailed in this
manual have been met.
Carefully inspect the entire venting
system for any signs of cracks or
fractures, particularly at the joints
between elbows or other fittings and the
straight runs of vent pipe.
Check the system for signs of sagging or
other stresses in the joints as a result
of misalignment of any components in the
system.
If any of these conditions are found, they
must be corrected in accordance with the
venting instructions in this manual before
completing the installation and putting
the water heater into service.
NOTICE: The vent piping must be
connected to the blower assembly
using the rubber coupling and
supplied clamps. The vent pipe
connections at the blower assembly
must be leak tested with soap and
water solution upon initial startup.
Repair any leaks before allowing
the water heater to operate.
