  Gas Piping   

•  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 

The water heater requires a standard 3 prong 120 VAC, 60 Hz properly grounded wall outlet.  Plug the 6ft long 
power cord into the wall outlet.
