Water temperature over 50°C can cause severe burns instantly or even
death from scalding. Hot water at 60°C can severely burn a child in less than
a second. At 50°C it takes five minutes. Always test the temperature of the
water before any use. To prevent these risks, Rinnai reccomends to consider
setting your hot water production at a maximum temperature of 50°C.
Do not store flammable objects near the appliance: it could cause a product
failure or fire. Do not spray aerosols in the vicinity of this appliance while it
is in operation.
Check that the appliance is supplied with the correct gas type and pressure
according to the data plate: ensure that the gas in use matches with the gas
indicated on the data plate. If not, there could be incomplete burning of the
gas, resulting in toxic emissions and/or product failure.
Do not insert objects into the flue outlet. Do not spray water directly into the
flue outlet. Keep, trees, shrubs, etc. well clear of the flue outlet. On colder
days steam may discharged from the flue outlet. This condition is normal for
high efficiency appliances and does not indicate a fault.
Do not touch the unit cover or the flue outlet.
Verify that the main gas tap is open before using the product.
It is recommended to use flexible metal fittings, specific for gas (and water),
in the appliance connections to the gas (water) network. Avoid using rubber
fittings that may deteriorate early.
Insert valves on the gas and on the water pipes to facilitate any maintenance
and safety in emergencies.
Before connecting the mains cable, check that the power supply is suitable:
make sure that the electrical system is up to standard and has a good earth
connection; otherwise the appliance may be damaged or malfunctioning.
It is not recommended to extend the supplied electrical cable (eg through the
use of extension cords or multiple sockets). In case of damage, replace the
electric cable with an original one. Replacement may only be performed by
Rinnai authorized technical personnel.
After installation (or long periods of inactivity) it is advisable to let the hot
water run before the use.
It is recommended the installation of a system to collect and drain water under the appliance in the case of water
leakage to prevent material and property damages.
Frost protection
: Make sure that the power cord of the appliance is
plugged-in and the electrical power is always available.
The frost protection system activates only when the appliance is electrically
powered.
All pipes must be wrapped with insulating materials to prevent heat loss.
The thickness of insulation should be between 25mm and 50mm according
to outdoor temperatures. Electrical hot wires could be installed to protect
pipework subjected to extreme cold or wind chill conditions. Hot wire use is
recommended if the case of temperature drops below -15°C.
If extremely freezing conditions are expected, turn off water and gas, and
drain all water from the appliance. If power and the automatic frost protection
are connected, freezing will be prevented. (Anti-frost protection is fitted as
standard equipment on all hot water units)
If water pipes are frozen, there would not be water flow in the system. Use a
heat source (e.g. hair dryer) to unfreeze the frozen components and pipes.
Before using the appliance after defrosting contact the Rinnai service to
verify possible damages.
