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 specic 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.

Note: CC3 Ducted Gas Heaters do not have on-board Add-On Cooling connections
1.2 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 from 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.

Brivis 10 Ducted Gas Heater IM
2.9 VENTILATION CALCULATIONS
For installation of internal heaters in a room, enclosure, residential garage, or plant room with natural ventilation
conditions, ensure adequate ventilation is available by utilising the following formulae:
Installation of a gas appliance in a room or enclosure for properties approved for
construction prior to 31st March 2014
a. Determine if the unit(s) MJ/hr rating for each cubic metre of the room or enclosure, is greater than 3 MJ/hr per m3.
Example:
Unit rating (Ur) = 120MJ/hr
Room volume (Rv) = 1m x 1m x 2.4m = 2.4m3
Ur/Rv = 120/2.4 = 50 MJ/hr per m3
As the result if greater than 3 MJ/hr per cubic metre of the space, additional ventilation is required.
b. Two permanent openings are required, each equivalent in area to the determined value A. The lower vent shall
be located close to the floor or at burner level for a Downflow unit. The upper vent shall be located at or above
the top of the unit. The two openings may be combined as long as the above conditions are met.
Determine free ventilation area using A = T x F, where:
A = minimum free ventilation area, mm2
T = total gas consumption of all gas appliances, MJ/hr. e.g. CC320I V2 = 90MJ/hr
F = factor (detailed in the table below)
Table 1. Ventilation F Factors
Gas appliance location Source of Ventilation Factor F
Gas appliance in a room or enclosure

Via an adjacent room 300
* Directly to outside means through an outside wall, into a cavity vented to outside, into an
underfloor space or roof space vented to outside.
Installation of a gas appliance in a room, enclosure, residential garage or plant room for
properties approved for construction after 31st March 2014
c. Determine if the unit(s) MJ/hr rating for each cubic metre of the room, enclosure, residential garage or plant room
is greater than 0.4 MJ/hr per m3.
Example:
Unit rating (Ur) = 120MJ/hr
Room volume (Rv) = 1m x 1m x 2.4m = 2.4m3
Ur/Rv = 120/2.4 = 50 MJ/hr per m3 > 0.4 MJ/hr per m3
As the result if greater than 0.4 MJ/hr per cubic metre of the space, additional ventilation is required.
Refer to AS/NZS 5601 for natural ventilation requirements.
Note: For all other applications, e.g. Mechanical Ventilation, refer AS/NZS 5601.

4. DUCTING INFORMATION
Good duct design and sizing are essential to every Central Heating system. Use the Product Sizing Guide and
technical data within this manual for the best results and follow these guidelines:
• Ductwork should be well insulated and airtight and have a minimum insulation rating of R1.0 (R1.5 in some
areas). Ensure that ducting complies with the Building Code of Australia.
• The ducting shall be well fastened to pops, BTOs, outlet boots and neck adapters adequately with duct tape, in
accordance with AS 4254.
• It shall also be properly sized, and curves and bends shall be smooth enough to ensure that the air flows
through efficiently, quietly and with minimal resistance.
• The registers and diffusers shall be large enough and of good design. They should minimise noise, while
providing the correct distribution pattern.
• The positive return air system shall be fitted with a grille large enough to accept the full air capacity of the
system at low noise levels and minimum resistance.
• If the system uses high level outlets (e.g. ceiling diffusers), then the return air inlet should be at a low level.
Ceiling systems with a high level return air may result in reduced performance.
Note: It is important that the ducting should be well insulated. It is mandatory under building codes to install insulated, fire rated duct.
4.1 RETURN AIR GRILLE
If a filter is fitted to the return air grille, make sure it is easily accessible for regular cleaning.

Note: Sizes are based on maximum airflow for typical 'egg-crate' grilles. For all other types, refer to the manufacturer’s specifications.
Example:If a grille has a free ventilation opening of 370mm x 560mm, the grille size is 0.37m x 0.56m = 0.21m².
This grille would be suitable for a CC315 & CC320 heater provided the grille does not have a filter fitted.

5. OUTLET CHART INFORMATION
The outlet chart (Table 4) provides recommendations based on the Product Sizing Guide or a system designed using
accepted design principles. The calculations use the typical size of registers and diffusers used on domestic heating
systems (300mm x 100mm floor registers and 150mm round ceiling diffusers) with 150mm ductwork.
For all systems, the minimum number of outlets, the outlet grille and the damper in the duct must all remain fully
open if the heater is to operate properly without overheating. Additionally, to ensure that the air velocity through each
ceiling outlet is sufficient, the maximum number of fully open ceiling outlets should not be exceeded (although the
system will operate efficiently with more ceiling outlets fully open if properly balanced).
There is not a limit/maximum number of floor outlets, so Table 4 lists the typical number for each heater model.
The outlet chart is divided into four columns as follows:
A. The maximum number of outlets that should remain fully open for a ceiling outlet system.
B. The typical number of outlets for a floor outlet system.
C. The minimum number of outlets that should remain fully open for floor/ceiling systems.
Note: Airflow figures are based on the maximum fan speed setting at total static pressure of 50Pa for 15, 20 & 25 kW models, 125Pa
for the 30kW model.

6. COMMISSIONING AND CONTROL SETTINGS
All of these heaters have been factory tested, but should be commissioned and adjusted in accordance with the
following instructions to ensure efficient and optimal heating performance. Remember:
• Mains power must be switched OFF before any wiring is touched.
• Commissioning must be carried out by a qualified trades person.
• If the heater cannot be adjusted to operate in accordance with these instructions, contact the Customer Service
Centre (refer to the back cover).
6.1 COMMISSIONING INSTRUCTIONS
6.1.1 Initial Damper Settings
Generally, a correctly designed and installed ducted system should have the following initial damper settings:
• Living areas: 100% open
• Bedrooms: 50% open
• Bathrooms, ensuite and laundry: 25% open.
6.1.2 Initial Ignition and Gas Inlet Pressure Check
a. Turn OFF the 240 Volt AC power supply at the fixed switched socket outlet adjacent to the unit.
b. Ensure the gas cock adjacent to the heater is in the OFF position.
c. Locate gas valve inlet pressure test point, remove the grub screw and insert your test point fitting (hose tail 1/8”
NPT).
d. Attach a manometer to the test point.
e. Ensure that all air has been purged from the gas piping and then turn ON the gas cock adjacent to the unit.
f. Turn on the 240 Volt AC power supply adjacent to the unit.
g. Go to the Thermostat, turn it ON and increase the temperature setting so that it calls for heat
h. The unit will now attempt to ignite. If the ignition attempt fails the heater will cycle through five ignition attempts
before locking out.
i. Once the ignition is successful allow the unit to run for one minute, ensuring the gas supply pressure does not
fall to below 1.1 kPa for natural gas and 2.7 kPa for LPG heaters. This should be done with all other gas
appliances operating at their full capacity.
j. If the reading is below the minimum requirement and cannot be adjusted any higher, this indicates the incoming
gas supply is inadequate (check supply pipe for blockage, check pipe sizing and gas meter size).
k. Turn the unit OFF at the thermostat, isolate the gas and the 240 Volt power supply adjacent to the unit.
l. Remove and replace test point with the grub screw.
Note: If there is air in the gas line, the heater may not ignite on the first attempt. Ignition attempts will occur automatically. Allow time
for the heater to rectify itself as it may simply be purging air.
If the heater does not attempt pilot ignition at all:
• Check the Lighting Procedure again and if it still fails to light, by-pass the Thermostat by removing cables from
the terminal block at the unit and link (bridge) terminals “R” and “W”. If it then lights, there is a fault with the
wires to the Thermostat or in the Thermostat itself. If it does not light, check the overheat switch has not tripped
or the 2 amp fuse has not blown.
6.1.3 Start & Check Burner Pressure
• Repeat steps 'a' to 'g' in Section 6.1.2. For step 'c' relocate the test point fitting from the inlet pressure test point
location to the burner pressure test point location, either on the gas valve or the manifold.
• Take a manometer reading of the test point pressure and confirm it is equal to the figure shown on the appliance
data label. If the pressure reading is not correct adjust the gas valve pressure regulator either up or down to
match the required test point pressure. If the pressure is lower than the required amount and cannot be adjusted
any higher, this indicates that the incoming supply pressure is not sufficient (check supply pipe for blockage,
pipe and gas meter sizing).
