Rinnai R63LSE2 - Manual (Page 19)

VA Series Outdoor LS Manual 19
Gas Piping
General Instructions
A manual gas control valve must be placed in the
gas supply line to the Rinnai water heater. A union
can be used on the connection above the shut off
valve for the future servicing or disconnection of the
unit.
Check the type of gas and the gas inlet pressure
before connecting the Rinnai water heater. If the
Rinnai water heater is not of the gas type that the
building is supplied with, DO NOT connect the water
heater. Contact the dealer for the proper unit to
match the gas type.
Check the gas supply pressure immediately
upstream at a location provided by the gas
company. Supplied gas pressure must be within the
limits shown in the Specifications section.
Before placing the appliance in operation all joints
including the heater must be checked for gas
tightness by means of leak detector solution, soap
and water, or an equivalent nonflammable solution,
as applicable. (Since some leak test solutions,
including soap and water, may cause corrosion or
stress cracking, the piping shall be rinsed with water
after testing, unless it has been determined that the
leak test solution is non-corrosive.)
Always use approved connectors to connect the unit
to the gas line. Always purge the gas line of any
debris before connection to the water heater.
The gas supply line shall be gas tight, sized, and so
installed as to provide a supply of gas sufficient to
meet the maximum demand of the heater and all
other gas consuming appliances at the location
without loss of pressure.
Any compound used on the threaded joint of the gas
piping shall be a type which resists the action of
liquefied petroleum gas (propane / LPG).
Refer to an approved pipe sizing chart if in doubt
about the size of the gas line.
Electrical Connection
The water heater must be electrically grounded in
accordance with local codes or in the absence of local
codes with the most recent edition of the National
Electrical Code, ANSI/NFPA 70. In Canada, all
electrical wiring should be in accordance with local
codes and the Canadian Electrical Code, CSA C22.1
Part 1. Do not rely on the gas or water piping to
ground the water heater. A screw is provided in the
junction box for the grounding connection.
The water heater requires 120 VAC, 60 Hz power from
a properly grounded circuit.
A disconnect switch must be provided and installed for
the incoming 120 VAC power. It should be a type that
is suitable for outdoor use. Check the National
Electrical Code, ANSI/NFPA 70 and your local codes
for a proper switch type to use in your area.
The wiring diagram is located on the Technical Sheet
attached to the inside of the front cover.
