Usage Features:
- Installation Flexibility: Designed for installation in roof spaces or beneath the floor, with specific clearance requirements detailed for both methods.
- Split Design: Compact Classic models can be split in half to ease installation, particularly in confined spaces.
- Duct Connection Options: Two options for return air connection are available: on the fan housing side (preferred, ex-factory) or on the motor side (alternate option, which may result in a nominal airflow reduction of 10%).
- Flueing: Requires a 100mm round single or twin wall non-corrosive metal flue, with maximum lengths specified (2m for single wall, 6m for twin wall). Horizontal flues must have a minimum rise of 20mm per 1m run. A Brivis Remote Flue Terminal can be used for horizontal flue termination on outside walls.
- Fan Speed Settings: Offers three fixed fan speed options: High (factory default), Medium, and Low, adjustable via terminals on the control board. This allows installers to optimize temperature rise at outlets based on the system type (floor or ceiling outlets).
- Add-On Cooling/Fan Only Operation: The Classic control board does not natively support "Add-On" cooling or "Fan Only" operation. An additional accessory, 'ACC LOOM ADD-ON RELAY CLASSIC' (Brivis Part No. B063283), must be fitted for these functionalities.
- Thermostat Compatibility: Requires a Brivis programmable thermostat for optimal operation, especially with add-on cooling.
Maintenance Features:
- Service Access: The heater must be installed in a position that allows adequate and safe access for service, with minimum clearances specified (e.g., 750mm minimum for service clearance, 200mm vertical clearance).
- L-Shaped Lid Removal: The L-shaped lid can be easily removed by unscrewing and lifting, providing access to controls for servicing.
- Return Air Grille: If a filter is fitted to the return air grille, it must be easily accessible for regular cleaning to maintain efficiency.
- Regular Servicing: Rinnai recommends that the appliance be serviced every 2 years by an authorized person.
- Troubleshooting Guidance: The manual includes instructions for initial ignition and gas inlet pressure checks, as well as troubleshooting steps for ignition failures, such as checking the thermostat wiring, overheat switch, and fuse.
- Leak Detection: After reassembly, the heater should be started up and tested for gas leaks using soapy water solution or a leak detector spray.
Installation Requirements and Warnings:
- Installation must comply with manufacturer's instructions, current AS/NZS 3000, AS/NZS 5601, AS/NZS 5141, AS 4254, HB 276-2004, local regulations, municipal building codes, and OH&S requirements.
- Installation, maintenance, and removal must only be carried out by an Authorised Person.
- The appliance is heavy; use 2 people or mechanical lifting device to prevent injury or damage.
- Do not modify electrical wiring. Damaged wiring must be replaced by an authorized person.
- Do not install on unstable or non-level surfaces.
- Gas supply piping must conform to AS/NZS 5601, and a gas cock must be fitted adjacent to the heater.
- Electrical supply must be 220-240V at 50Hz, plugged into a standard 10 Amp switched socket outlet.
- Ductwork must be well insulated (minimum R1.0, or R1.5 in some areas), airtight, and comply with the Building Code of Australia. Insulated fire-rated duct is mandatory.
- Ventilation calculations are provided for internal installations, requiring permanent openings if the unit's MJ/hr rating exceeds specified thresholds per cubic meter of room volume.
- Installer due diligence is crucial for changeovers, including comprehensive inspection of existing systems and correct commissioning to align with original system performance.
