A Successful Install
STARTS HERE
LOCATE EXHAUST TEE
& NEUTRALIZER
The exhaust tee and neutralizer
are shipped with the water heater
in a separate box and need to be
connected for proper operation.
GAS CONNECTION
Step 2,
Connect the Gas Line
For best performance:
• Ensure that all gas connections, regulator(s), and meter are sized properly
for the BTU/h rating (See Installation Manual for charts)
•
Regulator should be a minimum of 8' from the water heater
If installing more than one water heater, make sure each water heater
has a regulator
• Check all connections and fittings for leaks

PREPARE THERMAL
EXPANSION TANK
Make sure the thermal expansion
tank is properly sized for the
application and pressurized to
the building static water pressure.
INSPECT SHIPMENT

that may have
occurred during
shipping or handling.

VENTING
Step 3,
Hook Up the Intake and Exhaust
For optimum performance, proper venting
is essential.
Here are a few tips for installation:
• Calculate total equivalent feet.
90° and 45° elbows reduce the equivalent
vent length by the these values
• Ensure that vent runs are sloped
(1/4" per foot rise recommended)
• Install condensate drain / loop for air intake
• Rheem recommends long sweep elbows when possible
