INSTALLER’S INSTALLATION CONSIDERATION
( C o m m e r c i a l U n i t )
6) The appliance should be located in an area where water leakage from the unit
or connections will not result in damage to the area adjacent to the appliance
or to lower floors of the structure. When such locations cannot be avoided, it is
recommended that a suitable drain pan, adequately drained, be installed under
the appliance. The pan must not restrict combustion air flow. The manufacturer
is not responsible for any damage due to improper installation.
7) For an outdoor unit, do not install under an overhang less than 3 feet from the
top of the unit. When the overhang protrudes out over the Rinnai Water Heater
greater than 3 feet, the area under the overhang must be open on 3 sides.
8) Installer must install a Pressure Relief Valve. Pipe pressure relief discharge to
a drain or outside environment - see pressure relief valve page for details of
requirements.
1) A manual water control valve must be placed in the water inlet connection to the Rinnai
before it is connected to the water line. Unions may be used (and are recommended) on
both the hot/cold water supply lines, for the future servicing or disconnection of the unit.
2) All soldering materials and piping must be compatible with potable water.
3) Purge the water line to remove all debris and air. Debris will damage the Rinnai Water
Heater.
4) There is a wire mesh strainer on the Rinnai's inlet to prevent the introduction of debris to
the unit. It will need to be cleaned periodically. DO NOT operate unit without filter in place.
Clean this filter before leaving the job site.
5) It is recommended that auto drain down solenoids are installed in all applications where
below freezing temperature may occur.
WATER PIPING NOTES
Rinnai makes an installation kit available containing unions.
Do not reverse the inlet and outlet (cold and hot water) connections on the unit. This
would cause the Rinnai Water Heater not to operate.
