Installation Manual

Rinnai I-Series Condensing Boiler Solo Manual 69
Failure to properly commission the boiler as
described in this secon may result in
unreliable and unsafe burner operaon and
reduced component life.
Boiler commissioning is a procedure used
aer boiler installaon to ensure the system
and boiler were installed correctly and ready
for operaon.
THIS SECTION IS INTENDED
FOR THE INSTALLER
This boiler must be commissioned by a
licensed professional. Installer qualicaons:
A trained and qualied professional must
install the appliance, inspect it, and leak test
the boiler before use. The warranty will be
voided due to any improper installaon. The
trained and qualied professional should
have skills such as: Gas sizing; Connecng
gas lines, water lines, valves, and electricity;
Knowledge of applicable naonal, state, and
local codes; Installing venng through a wall
or roof; and training in installaon of
condensing boilers. Training for Rinnai
Condensing Boilers is accessible online at
www.trainingevents.rinnai.us.
1. Ensure all boiler components are installed
correctly.
2. Open the air vent inside the boiler.
3. Power on the boiler.
4. Open the ll valve on the lling 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 diagnosc code will be present unl the
boiler senses at least 13 PSI (90 kPa).
7. Check the heang system for leaks.
8. Begin the deaeraon process shown in the next
secon (“10.3 Deaeraon Process”).
• Work on the boiler must be carried out
by a licensed professional, using
correctly calibrated instruments with
current test cercaon. The
commissioning instrucons are intended
for licensed professionals who have the
necessary knowledge and are approved
for working on heang and gas systems.
• The fan will operate when power is
inially provided to perform a safety
check on the boiler.
• The boiler and its individual shut o
valve must be disconnected from the gas
supply piping system during any
pressure tesng of that system at test
pressures in excess of 1/2 PSI (3.5 kPa).
• Before the boiler is red for the rst
me:
− 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
secon)

WARNING
Do not ll the boiler unless permanent
power is available. Freeze protecon is not
available if the boiler is not lled, air
purged, and supplied with power and gas.
