C3 Gas Pipe Sizing
Gas pipe should be sized as per the requirements of AS/NZS 5601. The pipe sizing must be
sucient to deliver the following volume of gas to the heater with all other gas appliances in the
home running at the same time:
DL850 Gas Consumption = 38MJ/hr
DL1100 Gas Consumption = 42MJ/hr
C4 Gas Pipe Position
The DL850 / DL1100 have two possible entry points for gas pipe: on the rear right corner and
the front right. Each is sealed by either a plastic grommet or plastic plug. If you wish to use the
rear exit location, you may swap the grommet and plug positions.
The gas connection on the appliance is a ½” female BSP at the very front right of the appliance.
This section of the piping will need to be flexible to allow for pipe disconnection and firebox
removal.
C5 Gas Isolating Valve
It is recommended that a gas isolating valve be installed as close to the regulator on the gas inlet
side as possible with easy access if the fascia is removed. This will allow for easier servicing in the
future.
C6 Pressure Test Point
As per AS/NZS 5601, a pressure test point shall be provided by the installer prior to the inlet of
the appliance
Gas pipe entry positions
Regulator
Inlet gas connection
(Grommet)
(Plug)
Installer to swap plug and
grommet if required
END OF SECTION C
By the end of this section, you should have:
□ An unlined cavity with a standard three pin 230/240V AC supply that the appliance can
be plugged into
□ An electrical isolating switch that is accessible once the appliance is installed
□ A suitably sized gas supply to the right hand side of the appliance with a pressure test
point, ready to be connected once installed
□ Network cable installed, ready for plugging into appliance (if being connected to internet
router/network)
