Ariston GL 2.5 S Instructions Manual page 5

General remarks
CAUTION
The manufacturer cannot be responsible for the damages caused by improper
installation or by failure to follow instructions in this manual. Comply with the
installation instructions before completing electric connection.
CAUTION
The GL 4 CA S model is only approved for installations in Canada.
The thermostat has been pre-set at the factory at a temperature:
CAUTION
- Equal or below 51.7°C (125° F) for GL 2.5 S, GL 4 S and GL 6+ S for USA with UL
certification (See fig. 2/4).
- Equal to 60°C (140° F) for GL 4 S for Canada with CSA certification. Check local codes
to see if the installation of a tempering valve is required (See fig. 2/5).
CAUTION
Hydrogen gas can be produced in a hot water system served by this heater that has not
been used for a long period of time (generally 2 weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, it is recommended that the
hot water faucet be opened for several minutes at the kitchen sink before using any
electrical appliance connected to the hot water system. If hydrogen gas is present, there
will probably be an unusual sound such as air escaping through the pipe as the water
begins to flow. There should be no smoking or open flame near the faucet at the time.
Any water heater should be installed in such a manner that if it should leak, the resulting
CAUTION
flow of water will not cause damage to the area in which it is installed. National Plumbing
codes require a drain pan for any water heater installation. Failure to install one is the sole
responsibility of owner and/or installer. Reference UPC 2000 (Uniform Plumbing Code)
Section 510- Protection from Damage or IPC 2000 (International Plumbing Code) Section
504- Safety Devices.
