Usage Features:

Airflow Orientation: The 10kW Icebox models (DINIB10Z7-L and DINIB10Z7-R) are available in left and right-hand orientations, respectively. The 13kW and 15kW Icebox models (DINIB13Z7 and DINIB15Z7) are factory-set for left-hand orientation but can be converted to right-hand orientation by relocating the 'Top Rail' and 'Pop Cover Plate'.
Integrated Cooling: The Icebox uses the existing heating system's fan and ductwork, simplifying installation and reducing the need for separate air distribution components.
Condensate Drainage: All models include a 3/4" BSPM thread for connecting a drainpipe, which must have a continuous downward grade of not less than 1:50 to prevent pooling and corrosion.
Thermistor Location (BX5 Models): For BX5 models, the thermistor needs to be repositioned to the in-cabinet thermistor arm, ensuring the wiring is safely routed away from heat sources.
Communication Cable: A 2-core shielded communication cable (field supplied) is required between the Icebox unit (Terminals S1 & S2) and the outdoor condenser unit (Terminals S1 & S2), with the shield earthed at the condenser end only.
Control Wiring: 24-volt control wiring is installed from the Icebox electric box (Terminals A1, A2) to the Heater (StarPro series) or Brivis Thermostat.

Maintenance Features:

Service Clearances: A minimum clearance of 750mm on the sides and 500mm from the front of the unit, extending vertically one meter above the heater roof, is required for servicing.
Filtration: A filter must be fitted into the system and should be easily accessible for regular cleaning. Refer to the guidelines for return air filter grilles accompanying the Gas Ducted Heater.
Nitrogen Holding Charge: Icebox coils are supplied with a nitrogen holding charge (400kPa to 700kPa) to protect against leaks during transport. This charge must be checked prior to installation.
Regular Servicing: Rinnai recommends that this appliance be serviced every 2 years by a qualified technician.

Ductwork Design:

Good duct design and sizing are essential for efficient operation. Key considerations include:

Airtight and Insulated Ductwork: Ductwork should be airtight and have a minimum insulation rating of R1.0.
Proper Sizing and Smooth Bends: Ducts should be sized correctly with smooth curves and bends to ensure efficient, quiet airflow.
Register and Diffuser Design: Registers and diffusers should be large enough and designed to minimize noise while providing the correct distribution pattern.
Return Air System: A positive return air system with a grille large enough to handle the full air capacity at low noise levels is required.
Air Filtration: Adequate air filtration must be provided.
Outlet/Inlet Placement: If high-level outlets (e.g., ceiling diffusers) are used, the return air inlet should be at a low level.
Downstream Ductwork: A minimum of 1m, or preferably 2½ times the duct diameter, of straight ductwork must be installed immediately downstream of the Icebox unit before any divergence or branch-take-offs to avoid compromising airflow, system performance, and reliability.
Icebox Coil Placement: The Icebox coil unit must never be placed in the return air part of the duct system, as this can lead to condensation, corrosion, and damage to vital components in the Heater.

The Brivis "SuperSizeGuide" / Brivisize, Technical Data Sheets, or HB276 should be consulted for estimating cooling requirements and system design. All ductwork and fittings must be insulated, and fire-rated duct may be mandatory under some building codes.
