This manual must be followed exactly.
1) Read the Safety Issues section completely before installing the Rinnai Water
Heater.
2) This water heater is suitable for residential water (potable) heating ONLY. DO
NOT use this water heater for space heating, combination space heating/
domestic water heating, or commercial water heating applications. Doing so will
void the warranty.
3) The Rinnai Water Heater is not suitable for use as a pool or spa heater.
4) The indoor unit is designed to be installed indoors using the proper vent piping
to exhaust by-products of combustion to the outside environment. Contact
your dealer or Rinnai for proper vent kits. DO NOT operate this unit without
vent piping connected. Exhaust gasses must be expelled outside the home.
All pipe joints shall be taped to help prevent leakage around joints. (Aluminum
tape is recommended.)
5) Maintain proper space around the unit for proper servicing and operation.
Minimum clearances from combustible and non combustible materials are listed
below.
6) 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.
7) 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.
Manufacturer is not responsible for damage due to improper installation.
8) 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.
