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 appli-
ances 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 has 2 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 ap-
pliance. This section of the piping will need to be exible to allow for pipe disconnection
and rebox 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
