Water Connection; Gas Connection - Rinnai Infinity 16 external Operation And Installation Manual

2.4.2 WATER CONNECTION

Water pipe sizing and layout should be designed correctly to ensure the given water flows from the appliance are
available.
Prior to connect the water heater and not to invalidate the warranty, water line must be cleaned to remove any
impurity or production residue that could cause product malfunction.
The water connections are shown at the right table.
Where the water supply pressure exceeds 1,000kPa(10bar), an approved pressure reducing device must be fit at
the inlet of the appliance. To achieve the maximum rated flow a minimum water supply pressure of 140kPa(1.4bar)
is required at the appliance inlet. The unit will operate at lower supply pressures but the maximum flow rate may not
be achieved. Most installations will use high temperature setpoints which will reduce the available flow rate and heat
exchanger pressure drop, and therefore less pressure will be required at the inlet. Contact Rinnai or your supplier for
further instruction.
Connect the hot and cold water supply pipes. An approved isolation valve and strainer MUST be installed in the cold
water inlet pipe. An approved isolation valve and draining point should be installed in the hot water outlet pipe. There
must be a union or release fitting on the heater side of the isolation valves. An unvented kit to local regulations must
be installed in the pipework when the system is closed (i.e. has a flow and return, or tank).
If the heater is in a hard water area a suitable water conditioning system must be installed to prevent the build up of
limescale within the heat exchanger. Heat exchangers damaged by scaling are not covered by the manufacturer's
warranty.

All water pipework should be insulated to optimise maximum performance and energy efficiency.

2.4.3 GAS CONNECTION

Prior to connect the water heater and not to invalidate the warranty, gas line must be cleaned to remove any impurity
or production residue that could cause product malfunction.
Make sure that the appliance is set up for the correct type of gas.
The gas connection is shown at the right table.
The size of the gas meter (or regulator) and pipework must be sufficient for all appliances on the main. The gas
supply must be designed following the regulations in force and must provide the suitable dynamic pressure according
to the appliance nominal power. Gas pipe sizing must consider the gas input to this appliance as well as all the
other gas appliances in the premises. Sufficient gas must be available at the appliance if correct operation is to be
expected; insufficient gas will damage the unit.
The available gas pressure affects directly the power output and can result in discomfort if not correct. If the gas pipe
sizing is insufficient the customer will not get the full performance benefit.
An approved gas isolation valve must be fitted at the gas inlet. A union or release fitting should be installed after the
isolation valve in case of emergency and for maintenance.
Fuel quality: the appliance is designed to operate with a pure gas, otherwise an appropriate filter must be installed
on the gas line to restore the necessary quality
LPG tank: inert gas residues (e.g. nitrogen, etc...) could remain inside new tanks resulting in a poor gas mixture and
could cause malfunction or product failure. The gases in the mixture could become stratified during storage, causing
the variation of the fuel calorific value and altering the appliance efficiency.
