1. SCOPE

This installation manual is intended to be used as a guideline for the installation of Gas Fired Central Heaters.

It covers only the installation and commissioning of the heater and the allowable ueing congurations. Although recommended return air grilles and allowable duct outlet quantities are specied, it does not cover the actual ducting

design required to suit the installation.

This installation manual is based on Australian codes. For all other applications, please refer to local codes and

regulations.

These heaters must be installed and serviced only by qualied personnel. This manual applies to the following

models:

1.1 SP Heater Overview

SP6 series heaters are condensing heaters.

SP4 and SP5 series heaters are non-condensing heaters.

Universal models may be used in both internal and external applications.

For more details refer to Technical Specications section.

1.2 BX5 Heater Overview

The BX520 and BX526 ducted heaters are designed primarily to replace Bu󰀨alo 85 and Bu󰀨alo 120 heaters respectively. Their conguration allows for seamless changeover onto an existing base box, where applicable, with identical service connections, capacities and airows commensurate with the original units. They also incorporate on-board controls providing greater exibility for thermostat and zone control options.

Rinnai 7 Ducted Gas Heater IM

1.3 Installer Due Diligence for Changeovers

Modern ducted gas heaters, even those that are physically ‘like-for-like’, typically have di󰀨erent technical specications and control systems to existing, older models. Modern units usually have higher Star Ratings, which are accompanied by higher airows. Higher e󰀩ciency heaters with modulating gas valves also operate di󰀨erently to non-modulating

units.

When doing a direct unit change over:

Do a comprehensive inspection of the entire existing system to ensure it is ‘t for purpose’ with the new heater

•

Check existing items that are not being replaced; i.e. ensure the soundness and suitability of all ttings and

•

controls for use with the new ducted gas heater (e.g. Duct sizes, Flue, Return Air grille size, Thermostat, Zoning

etc.)

Correctly commission the new ducted gas heater – where possible, align it with the performance characteristics

•

of the original system – do not leave units at the factory default settings unless you are absolutely certain the settings are appropriate

Failure to observe best practice can lead to costly call backs for installers, unnecessary manufacturer warranty calls

and a poor customer experience.

With our policy of continuous improvement, we reserve the right to change, or discontinue at any time, specications

or designs without notice.

2. GENERAL PRODUCT GUIDELINES

2.1 APPLICATION AND SIZING

These heaters are designed to provide a central source of heat for a ducted central heating system.

The heaters should not be installed downstream from an air washer, an evaporative cooler or refrigerative cooling system. Nor are they designed to be installed on a marine craft, houseboat, or any similar environment.

The heaters must be installed in accordance with these instructions and related regulations, codes, standards, and authorities. These include but may not be limited to:

• AS/NZS 3000 - Electrical Installations

• AS/NZS 5601 - Gas Installations

• AS 4254 - Ductwork for air-handling systems in buildings

• HB 276 - A Guide to Good Practice

• AS/NZS 5141 - Residential Climate Control Systems

• Local Gas and Electricity Authority Codes

Note: The manufacturer assumes no responsibility for equipment installed in violation of any code, regulations and these installation

instructions..

It is recommended the Product Sizing Guide is followed in estimating heating requirements and for system design that will result in efficient installation and provide a higher level of comfort and economical operation.

For the hourly input and the gas type to be used, refer to the appliance data label located inside the service compartment or the Technical Specifications at the rear of this manual.

Note: All installations should only be carried out by a qualified tradesperson. Installations at altitudes above 1000m above sea level

may require main burner injector upgrading. Please contact the Customer Service Centre for advice.

• Product Sizing Guide

• Local Building Regulations

• Environment Authorities

• National Construction Code of Australia (NCC)

2.2 INSPECTION

This appliance has been inspected and tested at the time of manufacture and packaging and released for transportation without known damage. Upon receipt, inspect the exterior for evidence of rough handling in shipment. Ensure that the appliance is labelled correctly for the gas to which it is intended to be connected. If a discrepancy or damage to the appliance is identified DO NOT install the appliance and report findings back to supplier.

2.3 UNPACKING THE HEATER

Some heaters are supplied on a pallet with a plastic sleeve. To unpack:

Cut and remove the external plastic packaging and dispose of thoughtfully.

Remove heater from pallet (if supplied).

Some heaters are supplied with a base box assembly wrapped with a removable plastic film to protect the surface.

Note: Always remove and dispose of the plastic film before mounting the heater onto the base box.

2.4 UNLOADING OR LIFTING THE HEATER

When unloading or lifting the heater, ensure lifting equipment is in good operating condition and capable of lifting the total load. Be sure there is a clear area to place the heater down, which is within reach of the lifting equipment.

Note: Do not use the lifting handles provided to lift the heater above head height. If fitting the heater to elevated heights such as a

roof, use suitable lifting equipment.

Rinnai 9 Ducted Gas Heater IM

2.5 SERVICE CONNECTION GUIDELINES

2.5.1 Gas Inlet Connection

• All piping must be in accordance with AS/NZS 5601 and any local gas regulations.

• The connection point for universal and external model heaters is a female G3/4 compression fitting to AS 3688. This is either located on the outer cabinet of the heater, or supplied loose within the heater.

• The connection point for internal model heaters is a male G3/4 compression fitting to AS 3688.

• A gas cock shall be fitted in the gas line adjacent to the heater and in a convenient location so it can be turned OFF quickly and easily.

• The gas supply shall in no way interfere with any servicing of the heater.

Note: The gas supply must be installed by a licensed gas fitter. The gas pipe and gas meter should be sized so the heater can

maintain its required incoming gas pressure at maximum consumption with all other gas appliances operating at their maximum capacity at the same time as the heater.

2.5.2 Electrical Power Supply

The heater is pre-wired with a 3-pin plug and lead, and shall be plugged into a standard 10 Amp 220-240V fixed switched socket outlet adjacent to the heater in a convenient location so it can be turned OFF quickly and easily.

Note: A qualified electrician must install the 220 to 240 volt wiring according to local regulations.

IMPORTANT: Switch OFF the power and unplug the heater before touching any wiring. If any electrical wiring is damaged, it must

be replaced by the manufacturer, its service agents or an electrically qualified technician, in order to avoid a hazard.

The electricity supply must be 220-240V at 50Hz, and supplied by an authorised power supplier. Generators should never be used to supply this system as their output may be incompatible with, or prone to damage electronic components of the heater.
