MSA Controller: The MSA controllers (Pack A) and cables (Pack B) are optional accessories that electronically connect 2 to 5 water heaters and allows them to function as one hot water source. Two water heaters require one MSA Pack A. Each additional water heater beyond two requires one MSA Pack B.

EZConnect: The EZConnect cable is an optional accessory that electronically connects 2 water heaters and allows them to function as one hot water source.

PVA Valves: Pressure activated valves that allow each water heater (max 5) to turn on as necessary to meet the demand for hot water. A PVA valve is also useful when dedicating one Rinnai in a multiple Rinnai system for hot water circulation. The PVA valve will allow flow from the cold water supply to the dedicated unit when a differential pressure is exerted on the PVA valve due to domestic demand.

Remote Controllers: MC-91-1US - Controller included with the unit except for the V53e and V53i. MCC-91-1US - For commercial and hydronic applications allowing temperatures above 140º F. MC-100V-1US - Deluxe controller BC-100V-1US - Bathroom controller

Rinnai is continually updating and introducing new products and accessories. For the latest information, contact Rinnai at 1-800-621-9419, FAX: 1-888-474-6624, or www.rinnai.us.

Rinnai Accessories Multiple Unit Connections (refer to model applicability)

• Do not install both the EZConnect and the MSA packs because they are not designed to operate together.

• Water heaters connected with the EZConnect Cable or the MSA packs cannot be used for the bathfill function.

• Temperature settings can only be changed on the controller for the primary unit. • Do not use the EZConnect or MSA packs with storage tank applications.

Guidelines for multiple unit connections:

Rinnai Installation Kits - available with threaded (F) or sweated (C) connections; provides isolation valves, pressure relief valve, and full port drains with easy union installation

Recess Boxes: Recesses unit into the wall, protecting and hiding the unit from view

Pipe Covers: For security, weather protection, and finished look

Water Quality and Scale

A complete water analysis and an understanding of system requirements are needed to protect the Rinnai tankless water heaters and water heating systems from scale. Water analysis shows whether water is hard or soft. Hard water, unless treated, will cause scaling or liming of the Rinnai heat exchanger. The rate of scaling increases with temperature and usage because calcium carbonate and other scaling compounds lose solubility (fall out of solution) at higher temperatures. For example, for every 20°F over 140°F, the rate of scale increases by a factor of 2 (See figure below). Reference target water quality levels found in the operation / installation manual and consider water treatment if these levels are exceeded. *

Pump Sizing for Circulation

1. Use the chart below or one appropriate for your conditions to determine the heat loss in the length of the hot water supply and return piping. For example, 100 ft of 1-1/2 in bare copper tubing results in a heat loss of 5300 Btu/h.

2. Determine the acceptable temperature drop at the last fixture in the loop. For example, if the supply temperature from the water heater is 120 ºF (49 ºC) and an acceptable temperature at the last fixture is 100 ºF (38 ºC) then the acceptable temperature drop is 20 ºF (7 ºC).

3. Calculate the required pump flow rate using the following formula:

FLOW RATE (gpm) = HEAT LOSS (BTU / h)

500 X ACCEPTABLE TEMPERATURE DROP (ºF )

4. Based on the above calculations select a pump for the type of circulation system you will be utilizing:

A). Optional Method (reference drawing WH1-C-O) - Reference pump manufacturers flow vs. pressure specifications to select a pump that can provide the flow rate calculated above while overcoming the pressure loss through:

• Tank water heater (reference manufacturer’s information)

• All building supply and return plumbing in the circulation loop (reference local plumbing codes, standards, or practices)

B). Preferred Method (WH1-C) - Reference pump manufacturers flow vs. pressure specifications to select a pump that can provide 3 gpm of flow or the flow rate calculated above, whichever is greater, while overcoming the pressure loss through:

• Rinnai tankless water heater (reference flow vs. pressure curve of the Rinnai model being used)

• Optional storage tank (reference manufacturer’s information)

• All building supply and return plumbing in the circulation loop (reference local plumbing codes, standards, or practices)

NOTE: Only use pumps of brass, bronze, or stainless steel construction. Do not use pumps of iron construction as they will oxidize and clog the inlet filter on the appliance. The pump should be controlled by an aquastat, timer, or combination of the two. A demand control (motion sensor, push button, or door contact) may also be used.

Tank Water Heaters in a Circulation Loop

The following applies when using a tank water heater (gas or electric) to provide heat for a circulation loop. Drawing WH1-C-O is an example. The heat output of the tank must be equal to or greater than the calculated circulation loop heat loss. (Reference page 7, Step 1 on calculating heat loss). Electric Tank Water Heater

Since the input and output are the same for an electric tank water heater, this can be expressed as:

Electric Tank Input (Kw) > Circulation loop heat loss (Btuh) 3413

(1 Kilowatt = 3,413 BTU) Gas Tank Water Heater

When using a gas style water heater, the efficiency of the tank must be taken into account.

Available Btuh output = (Btu input of tank) x (efficiency) > Circulation loop heat loss (Btuh)

Example:

30,000 Btuh input gas tank 0.62 Efficiency

30,000 x .62 = 18,600 available Btuh output

Additional Guidelines Rinnai water heaters not recovering a storage tank: In applications involving a commercial dishwasher, a hot water circulation loop feeding the dishwasher is required.

Rinnai water heater recovering a storage tank: In applications involving a commercial dishwasher, a hot water circulation loop feeding the dishwasher may be required depending on the distance between the dishwasher and the storage tank. Refer to local codes when determining the need for circulation loops to dishwashers.

When using the Rinnai water heater as the heat source for circulation loop, the piping systems should be designed with a hot water circulation loop having a minimum circulating flow rate of 3 gpm. Also review the pressure drop curves for the Rinnai water heater when sizing circulators.

Rinnai water heaters cannot be used in applications requiring 180º-195º F water at a DISHWASHER, unless a booster heater capable of producing 180º-195º F water is provided at the dishwasher. The Rinnai water heater is not to be used as a booster water heater in these applications.

For beauty salon applications, a hot water circulation loop feeding the head wash stations is highly recommended. This provides instant hot water to the head wash stations and reduces the possibility of cold bursts at the stations. (Refer to the piping schematics in this manual.) Insulation of circulation piping is also recommended for heat retention.

Exhaust gases from beauty salon applications and fume hoods of commercial dish washers with chemical sanitizers can be highly corrosive and may cause premature failure of water heater components. Care must be taken to ensure that the water heater and vent termination are installed away from that area. An uncontaminated supply of combustible air m ust be maintained for optimum performance of the unit.

If the intended installation is located in a hard water area, a softener or alternate water treatment system must be used. Perform routine maintenance as necessary.

For any applications requiring temperatures above 140º F, an MCC-91 temperature controller must be purchased separately.

The following applies when using Rinnai tankless water heaters to recover a storage tank. Drawing WH1-BC is an example.

Rinnai Tankless water heaters have a pressure loss which must be considered in the system design. Reference the pressure loss curve for the Rinnai model being used to determine the pump size for the desired recovery rate.

For recommended pump sizes use the table below. Additional pressure losses in plumbing between the Rinnai(s) and the storage tank must also be taken into consideration.

The specified pump size is to provide maximum recovery of the storage tank. A smaller pump size may be used, but could result in longer recovery time of the tank. Please contact the engineering department with any questions on pump sizing.

NOTE: Only use pumps of brass, bronze, or stainless steel construction. Do not use pumps of iron construction as they will oxidize and clog the inlet filter on the appliance.
