Gas Connections - Waterco Turbotemp 200HD Installation And Operation Manual

FLOW SWITCH
If the heater is installed more than 1.5 m above the pool or more than 1.2 m below the
pool level, you will be beyond the limits of the pressure switch and a flow switch must
be installed. Locate and install the flow switch externally on the outlet piping from the
heater, as close as possible to the heater. Connect the flow switch wires in place of the
water pressure switch wires.

GAS CONNECTIONS

GAS LINE INSTALLATIONS
The gas supply must be installed in accordance with the Gas Installation Code, AS/NZS 5601.1,
as applicable and all applicable local codes.
Before installing the gas line, be sure to check which gas the heater has been designed to burn.
This is important because different types of gas require different gas pipe sizes. The rating plate
on the heater will indicate which gas the heater is designed to burn. Table 2 below shows the
recommended gas inlet pipe sizes required for the distance from the gas meter to the heater.
The table is for natural gas at a specific gravity of .65 and propane at a specific gravity of 1.55.
When sizing gas lines, calculate 0.9 additional meters of straight pipe for every elbow used.
When installing the gas line, avoid getting dirt, grease or other foreign material in the pipe as
this may cause damage to the gas valve, which may result in heater failure.
The gas meter should be checked to make sure that it will supply enough gas to the heater and
any other appliances that may be used on the same meter. Insufficient gas supply will cause
the heater to operate below its designed performance or not at all. The gas line from the meter
will usually be of a larger size than the gas valve supplied with the heater. Therefore a reduction
of the connecting gas pipe will be necessary. Make this reduction as close to the heater as
possible. Gas supply companies are increasingly supplying natural gas to new installations
with 2.75 kPa; this means if the gas pressure is not adjusted to the correct working pressure,
the heater will be over gassed and cause serious damage within minutes. This damage is not
covered under the heater warranty.
Install a manual shut-off valve that conforms with Type 1 or Type 2 as per AG201 and/or AS4617
standards, and a sediment trap/drip leg and union located outside the heater panels, see Figure
6. Do not use a restrictive gas cock.
The heater and any other gas appliances must be disconnected from the gas supply piping
system during any pressure testing on that system, (greater than 6.0 kPa). The heater and its
gas connection must be leak tested before placing the heater in operation. Do not use flame
to test the gas line. Use soapy water or another nonflammable method.
NOTE
A manual main shut-off valve must be installed externally to the heater.
!
WARNING
DO NOT INSTALL THE GAS LINE UNION INSIDE THE HEATER CABINET. THIS WILL
VOID YOUR WARRANTY.
