THIS SECTION IS INTENDED
FOR THE INSTALLER
This boiler must be commissioned by a
licensed professional. Installer qualifications:
A trained and qualified professional must
install the appliance, inspect it, and leak test
the boiler before use. The warranty will be
voided due to any improper installation. The
trained and qualified professional should
have skills such as: Gas sizing; Connecting
gas lines, water lines, valves, and electricity;
Knowledge of applicable national, state, and
local codes; Installing venting through a wall
or roof; and training in installation of
condensing boilers. Training for Rinnai
Condensing Boilers is accessible online at
www.trainingevents.rinnai.us.
Boiler commissioning is a procedure used
after boiler installation to ensure the system
and boiler were installed correctly and ready
for operation.
WARNING
Failure to properly commission the boiler as
described in this section may result in
unreliable and unsafe burner operation and
reduced component life.

IMPORTANT
•
Work on the boiler must be carried out
by a licensed professional, using
correctly calibrated instruments with
current test certification. The
commissioning instructions are intended
for licensed professionals who have the
necessary knowledge and are approved
for working on heating and gas systems.
•
The fan will operate when power is
initially provided to perform a safety
check on the boiler.
•
The boiler and its individual shut off
valve must be disconnected from the gas
supply piping system during any
pressure testing of that system at test
pressures in excess of 1/2 PSI (3.5 kPa).
•
Before the boiler is fired for the first
time:
−
Ensure the boiler and system are
fully de-aerated
−
Purge the gas line between the gas
meter and boiler
−
Prime the pump (as described in this
section)
IMPORTANT
It is recommended to fill the boiler with
power supplied to the boiler. If power is
not supplied, freezing and pump lockup
issues could occur.
1. Ensure all boiler components are installed
correctly.
2. Open the air vent inside the boiler.
3. Power on the boiler.
4. Open the fill valve on the filling circuit.
5. Check the pressure on the controller and/or
pressure gauge. Fill the boiler to a minimum of
20 PSI (138 kPa) water pressure and a maximum
of 30 PSI (207 kPa).
6. An E430 diagnostic code will be present until the
boiler senses at least 13 PSI (90 kPa).
7. Check the heating system for leaks.
8. Begin the deaeration process shown in the next
section ("10.3 Deaeration Process").
