Venting Instructions (V53i)
Intake / Exhaust Guidelines
•
This water heater is a direct vent water heater and
therefore is certified and listed with the vent
system. You must use vent components that are
certified and listed with the water heater model.
•
Do not combine vent components from different
manufacturers.
•
The vent system must vent directly to the outside
of the building and use outside air for combustion.
•
Venting should be as direct as possible with a
minimum number of pipe fittings.
•
Avoid dips or sags in horizontal vent runs by
installing supports per the vent manufacturer's
instructions.
•
Support horizontal vent runs every four feet and all
vertical vent runs every six feet or in accordance
with local codes.
•
Vent diameter must not be reduced.
•
Do not connect the venting system with an existing
vent or chimney.
Condensate
Condensate formation can occur in high efficiency
direct vent appliances. To prevent condensate
damage follow these instructions.
• Vertical terminations must incorporate a
condensate drain and trap as close as possible to
the appliance.
• The V53i water heater has an integrated
condensate collector.
• Rinnai offers a condensate trap.
• Regions of cold climate will create more
condensate in the vent system. The condensate
collector should be used in cold climates.
• Use only vent that is approved and identified as
acceptable for your particular model.
• Do not use PVC, CPVC, ABS or galvanized
material to vent this appliance.
• Slope the venting toward the appliance according to
the vent manufacturers installation instructions.
• All condensate must drain and be disposed of per
local codes.
• Use only PVC or CPVC pipe for the condensate
drain line.
• The condensate drain pipe should be as short as
possible and have a downward pitch.
• Do not connect the condensate drain pipe directly
to the rain sewer.
Refer to the specific instructions on your vent product for additional
installation requirements.
V53i & V53e Operation and Installation Manual
•
Do not common vent with the vent pipe of any
other water heater or appliance.
•
Vent connections must be firmly pressed together
so that the gaskets form an air tight seal.
•
The vent piece connected to the water heater must
be secured with one self-tapping screw.
•
Refer to the instructions of the vent system
manufacturer for component assembly instructions.
•
If the vent system is to be enclosed, it is suggested
that the design of the enclosure shall permit
inspection of the vent system. The design of such
enclosure shall be deemed acceptable by the
installer or the local inspector.
NOTICE
If it becomes necessary to access an enclosed vent
system for service or repairs, Rinnai is not responsible
for any costs or difficulties in accessing the vent
system. Warranty does not cover obtaining access to
an enclosed vent system.
WARNING
The condensate trap must be primed before operation
to prevent exhaust gases from entering the building.
NOTICE
Provisions must be made to prevent the condensate
from entering the water heater. Without proper
drainage or disposal, condensate will damage the heat
exchanger.
• The condensate drain pipe (along its entire length)
must be at least the same diameter as the drain
line.
• The end of the condensate drain pipe should be
open to the atmosphere. The end should not be
under water or other substances.
• Do not connect the condensate drain line with an
air conditioning evaporator coil drain.
• To minimize freezing of the condensate, run the
condensate drain line through an interior wall or
between insulation and an interior wall.
• The condensate collector should be used for all
hydronic heating applications.
