Installation Manual
46 Rinnai I-Series Condensing Boiler Solo Manual
• The boiler shall be installed such that
the gas ignion system components
are protected from water (dripping,
spraying, rain, etc.) during appliance
operaon and service (circulator
replacement, condensate trap, control
replacement, etc.).
• A sediment trap must be provided
upstream of the gas controls.
• A manual gas shuto valve between
the gas supply and the boiler must be
installed.
• A licensed professional must install the
gas supply.
• Turn o 120V power supply.
• Turn o the gas.
• Gas is ammable. Do not smoke or
provide other ignion sources while
working with gas.
• Do not turn on the boiler or gas unl all
fumes are gone.
1. Check the type of gas and gas supply
pressure before connecng the boiler. If the
boiler is not of the gas type that the building
is supplied with, converng the gas type of
the boiler is necessary. A gas conversion kit is
included with the boiler. Refer to secon
“14.4 Gas Conversion” in the Appendix for
gas conversion instrucons.
2. Check the gas supply pressure immediately
upstream at a locaon provided by the gas
company. Supplied gas pressure must be
within the limits shown in secon “3.4
Specicaons” with all gas appliances
operang.
3. Before placing the appliance in operaon, all
joints including the heater must be checked
for gas ghtness by means of soap, gas leak
detector soluon, or an equivalent
nonammable soluon, as applicable. Since
some leak test soluons, including soap and
water, may cause corrosion or stress
cracking, the piping shall be rinsed with
water aer tesng, unless it has been
determined that the leak test soluon is
non-corrosive.
4. Use approved and appropriately sized
connectors to connect the boiler to the gas
line. Purge the gas line of any debris before
connecon to the boiler.
5. Any compound used on the threaded joint of
the gas piping shall be a type that resists the
acon of liqueed petroleum gas (propane/
LPG).
6. The gas supply line shall be gas ght, sized,
and so installed as to provide a supply of gas
sucient to meet the maximum demand of
the heater and all other gas consuming
appliances at the locaon without loss of
pressure. If in doubt about the size of the gas
line, refer to secon “6.3 Gas Pipe Sizing
Reference Tables.”
7. Perform a leak and pressure test prior to
operang the boiler. If a leak is detected, do
not operate the boiler unl the leak is
repaired.
