Venting 

Instructions      

 

 

 

 

 

 

 

 

 

 

 

 

• 

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.

 

• 

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.

 

• 

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.

 

Intake / Exhaust Guidelines 

Refer to the specific instructions on your vent product for 
additional installation requirements. 

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. 

• 

Use only vent that is approved and identified as 
acceptable for condensing appliances. 

• 

Do not use aluminum, 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 dispose of per local 
codes. 

• 

If the condensate drain gets blocked, an error code 
will display on the controller. If this occurs, the 
condensate drain must be cleaned. 

• 

The condensate trap will automatically prime (self-
prime) during operation of the unit as condensate 
forms.  Condensate draining from the unit indicates 
that the trap is full and that there is no blockage in 
the condensate drain.  It is not necessary to add 
water to the condensate trap. 

• 

Use only PVC or CPVC pipe for the condensate 
drain line.   

• 

The drain pipe (along its entire length) must be at 
least the same diameter as the drain line, (1/2 inch 
NPT). 

Condensate  

The Rinnai RC80i and RC98i condensing tankless 
water heaters are factory equipped with a condensate 
trap and drain line. 

NOTICE

 

Do not plug or cap the integrated condensate line. 
Without proper drainage or disposal, condensate will 
damage the water heater. 

• 

The drain pipe should be as short as possible and 
have a downward pitch. 

• 

The end of the drain pipe should be open to the 
atmosphere.  The end should not be under water or 
other substances. 

• 

Do not connect the drain pipe directly to the rain 
sewer. 

• 

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.
