2.6 INSTALLATION
2.6.1 CLEARANCE
The appliance must be installed in an easily accessible position. Sufficient
clearances for component removal and product maintenance must be
guaranteed.
INDOOR model: the minimum frontal clearance distance for the appliance
is 50cm.
OUTDOOR model: the minimum frontal clearance distance for the
appliance is 50cm. For a correct operation of the product, any architectural
elements placed in front of the appliance, DO NOT have to create zones of
differentiated pressure (refer to the image on the side).
IMPORTANT
There must not be any obstacles, even partial, placed on the front of the appliance: this will allow
the appliance to work correctly even in strong wind conditions.
2.6.2 WATER CONNECTION
The sizing and layout of the water pipes must be designed correctly to ensure adequate water flow to the appliance.
Prior to installing the appliance, to avoid invalidating the warranty, it is necessary to clean the pipes to remove any
impurities or production residues that could cause the product to malfunction.
The water connections are 15A (R1/2”) male.
If the water supply pressure (cold water inlet) exceeds 8 bar, a pressure reducer must be installed. In order to achieve
maximum flow it is necessary to guarantee a pressure of 0.8bar. The appliance can also work at lower pressures,
but the maximum capacity will not be guaranteed. When water is used at high temperatures, the available flow rate
decreases and, as a consequence, also the pressure drops in the heat exchanger: a lower pressure at the inlet will
therefore be required. Contact Rinnai or your supplier for further instructions.
When connecting the water supply pipes, it is recommended to have a valve and a filter on the cold water inlet union,
and a valve on the hot water outlet. Do not connect the valves directly to the water heater’s connections, but interpose
a flexible connection joint.
If the appliance is supplied with water of poor quality, it is necessary to install an adequate water treatment system
(water softener), to limit the scale of limestone and the encrustation on the heat exchanger. The warranty does not
cover damages caused by limescale. Below are some limit values of substances dissolved in water to respect:
Description pH
Total
dissolved

Chlorides Magnesium Calcium Sodium Iron
Max value 6.5-9.0 600mg/litre 150mg/litre 300mg/litre 10mg/litre 20mg/litre 150mg/litre 1mg litre
The hydraulic pipes should be well insulated to optimize energy efficiency and reduce heat losses.
2.6.3 GAS CONNECTION
Prior to installing the appliance, to avoid invalidating the warranty, it is necessary to clean the gas line to remove any
impurities or production residues that could cause the product to malfunction.
Make sure the appliance is set up for the type of gas used.
The gas connection is 15A (R1/2”) male.
Check that the meter and the gas pipe are adequate to the power of the appliance (including all the appliances
connected to the same gas line): the gas network must be designed by qualified professionals and according to current
regulations; must provide adequate dynamic pressure based on the rated power of the device. Refer to what reported
by the National Standards.
