Rinnai RC80I Electrical Connection, Error Indication or Air Handler Control Switch, Gas Piping

Page 18

Electrical Connection

The water heater requires 120 VAC, 60 Hz power from a properly grounded circuit.

If using the 6 foot long power cord, plug it into a standard 3 prong 120 VAC, 60 Hz properly grounded wall outlet. The wiring diagram is located on the Technical Sheet attached to the inside of the front cover.

The water heater must be electrically grounded in accordance with local codes, or in the absence of local codes with the National Electrical Code, ANSI/NFPA 70 and/or the CSA C22.1, Canadian Electrical Code.

Error Indication or Air Handler Control Switch

When using the Rinnai water heater with an Error Indication Switch, switch No. 4 in the bank of 8 switches should be in the off position. This is the default position.

To connect the water heater to the Rinnai Air Handler, the Control Switch is necessary to function as the electrical connection. When the Control Switch is functioning as the electrical connection between the water heater and air handler, switch No. 4 in the bank of 8 switches should be in the on position.

The Error Indication Switch and the Rinnai Air Handler Control Switch are optional products available from Rinnai. Installation instructions are included with these products.

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.
