WATER & GAS PIPING INSTALLATION» The following plumbing drawings are not intended to describe acomplete system. It is up to the engineer/contractor to determine thenecessary components needed for the configuration of the particulary p g psystem being installed.

» The following plumbing drawings do not imply compliance with localg p g g p y pbuilding code requirements. It is the engineer/contractor’s responsibilityto ensure the installation is in accordance with all local and state buildingcodes. Confer with your local building officials before installation.

» All water and gas lines MUST be installed by a qualified or licensedplumber or gas technician.

Sizing Guidelines• Each installation is unique and can vary depending on the application, demand, and

input/output characteristics (i.e. incoming water temperature, pipe sizing, etc). F th d t t t i t th i fl t hi d bFurthermore, ground water temperature can impact the maximum flow rate achieved by the product. It is important to contact Rinnai’s Engineering / Applications department for assistance in sizing all residential and commercial jobs. Please call 1-800-621-9419 for support or utilize Rinnai’s sizing calculators available at www.rinnaisolutions.com.

• Commercial dishwashers;

• 1. Typically, in applications involving commercial dishwashers, two or more tankless water heaters are needed. Contact Rinnai Engineering / Applications department at 1-800-621-9419 for proper sizing in all commercial dishwasherdepartment at 1-800-621-9419 for proper sizing in all commercial dishwasher applications. (Have the dishwasher model number available).

•• 2. A circulating system is required in all commercial dishwasher applications to

ensure you have hot water available at the dishwasher when it calls for hot water. CCirculating systems are also required in tank water heater applications.

• 3. DO NOT use a tankless water heater as a booster heater for commercial dishwashers. When using a tankless water heater in conjunction with a hot water sanitizing type dishwasher a booster heater recommended by the dishwasher


sanitizing type dishwasher a booster heater recommended by the dishwasher manufacturer must be used.

Multiple UnitMultiple Unit

MSA Controls InstallationMSA Controls Installation

Use MSA controls when banking multiple units on the same manifold system in residential or commercial applications. The MSA controls will sequence or rotate between units to prevent one unit from being a “work horse”. In addition, p g ,these controls ensure each unit is firing at the same rate during operation, and it electronically balances the flow rate through each unit, eliminating the need for balancing valves.


MSA - 2M Master Board and wiring harness (MSA-2S) Connections

Manifold Controls g ( )

When manifolding two R98/C98 Models, an MSA b d i t Aboard is not necessary. An

EZConnect cable can be used connecting to a special harness

on the primary unit (picture below) and the PCB on the secondary unit (picture tosecondary unit (picture to

right). Three or more R98/C98 Models will require the MSA

components.

In an MSA configuration, a special harness connects to the MSA controller board (left arrow), a single red wire (middle arrow),


and each unit’s PCB (right arrow).
