Tankless Rack System
By Rinnai
Rinnai’s objective:
To supply a packaged water heater solution as fully assembled systems. The system/kit would include all water/gas connections and manifolds under the units. Installer mounts rack system with any necessary venting and connects his utilities at which time the system is ready for operation
– Offerings to include;• In-Line or Wall Mount – 2 & 3 unit rack • Back to Back Mount; 2 – 4 or 3 - 6 unit rack• Rack systems can be combined in combinations up to 25 water heaters.

Features and Benefits:
•Pre-assembled rack with water heaters installed
•Racks can be used with RU98 indoor/outdoor water heaters ONLY
•In-Line or Back to Back free standing options
•Gas and water manifolds properly sized for each rack system
•Rinnai MSB electronic control system available for linking up to 25 units
•MCC-91-2 commercial controller available for temperatures between 140˚F and 185˚F

– Uni-Strut Vertical legs /Sheet Metal bracing.• Uni-Strut – Galvanized Steel• Sheet Metal is 0.090” Aluminum w/powder coat
– Frame uses (12) 5/16” threaded bolts to secure the top and center bracing.
– Use up to #10 screws to mount to wall studs, 0.219” holes are 2” apart for ease of installation
• Manifold Kits– Hot & Cold Water – Type “L” Copper – Manifolds properly sized to handle maximum flow of system – Universal manifold for hot /cold water lines– Gas – Black Iron w/powder coat
• Branch Lines– CSST ¾” from water heaters to manifolds - all connections– RIK kits include for hot/cold water feeds to manifold. – ¾” manual shut off or service valve provided for each water heater– ¾” CSST gas branch lines with yellow epoxy coating

REU-MSB Control System:
•The MSB-M main board is supplied with (2) MSB-C1 cables, (one short & one long) to connect the first two units up to the main MSB-M board.
•Additional MSB-C1 cables will be needed to connect a third, forth or fifth unit to a MSB board. If installing more than five units the combination of MSB-M boards plus C1 and C2 cables will be determined on site based on the water heater configuration you choose.
•Up to 5 MSB-M boards can be linked together with communication cables (MSB-C2’s) allowing up to 25 water heaters to operate as a single system.
•An MSB system could have an operating range from 10,000 BTU to as great as 5 million BTU’s in terms of flow rate, from 0.4 gpm to 245 gpm.
•When multiple water heaters are linked together with MSB controls, they will attempt to supply equal amounts of hot water. They will also rotated occasionally to ensure equal usage among the entire system.
•On initial water flow 1 to 3 units will fire up based on the dip switch configuration of the Main MSB board. Once the flow rate is determined, the MSB board will cycle additional units on or off as needed. Water heaters not firing will close their servo valves.
MSB System

MSB Control System continue
•The temperature setting for all water heaters in a manifold system are controlled by the primary unit connected to the Main MSB board. The temperature controllers connected to other units will display the set temperature selected on the primary unit and cannot be adjusted individually. Additionally they will display error codes and can be used for diagnostics for that particular unit.
•If a water temperature over 140 ˚F is desired, the MCC-91-2 controller must be installed on the water heater with the Main MSB board.
• Dip switches on the MSB-2M board determine the number of units in standby. It is recommended that the Main MSB-M board dip switches are set for three units to be in the standby mode. All other MSB-M boards should be set to one unit in standby. Place dip switch #1 and #2 on the Main MSB-M board to the “OFF” position, this will place three units in the standby mode. Place dip switch #1 & #2 to the other MSB-M boards to the “ON” position. That will place one unit in those banks in the standby mode. The system will always allow three units to be in standby, as long as the Main MSB-M board is set to three units as explained above.

MSB Control System (continued)
All MSB boards must be set up to communicate with the other boards. This is achieved by setting the dip switches on the MSB boards to the proper positions, follow steps a – e below:
MSB System

Dip switches
a. Set dip switch #3 on the Main MSB board to the “ON” position.
b. Set dip switch #4 on the second MSB board to the “ON” position.
c. Set dip switch #3 & #4 on the third MSB board to the “ON” position.
d. Set dip switch #5 on the fourth MSB board to the “ON” position.
e. Set dip switch #3 & #5 on the fifth MSB board to the “ON” position
In all steps, LED #6 will light to confirm connection.
