Temperature And Pressure Relief; Scalding - HTP Everlast 18 Manual De Uso Y Mantenimiento

NOTES:
1. Minimum pipe size should
match connection size. Upsize
pipe accordingly if greater flow
is required.
2. Drains and check valve
between will assist in purging
air from system.
3. These drawings are meant
to demonstrate system piping
only. The installer is responsible
for all equipment and detailing
required by local codes. In
Massachusetts, you must install
a vacuum relief valve per 248
CMR.
4. A temperature and pressure
(T&P) relief valve is not required
for most installations, but may
be required to meet local,
state, or provincial codes. If
codes require a T&P valve,
install according to code and
manufacturer instructions.
5. Mixing valve applications are recommended to help prevent scalding.
6. It is highly recommended by the manufacturer to install water leak detection devices and automatic shutoff valves in
any water heater installation where a leakage of water could result in property damages.
C. Temperature and Pressure Relief
This tankless water heater is equipped with both computer temperature control and mechanical auto resetting
high limit switches for high limit temperature protection. This product does not use a storage tank and a
temperature pressure relief valve (T&P) is not required for most installations. UL Standard 499 does NOT require
that a pressure relief valve be used.
However, a T&P valve may be required to meet installation codes in your area. If one is required, install the valve
in accordance with local codes. Ensure that it operates correctly and that air is purged from the valve before using
the water heater. When connecting to flex or high temperature CPVC pipe, it is recommended that a T&P valve
be used for added safety.
NOTE: Installations in the Commonwealth of Massachusetts and State of Kentucky require a pressure relief valve.
Please check local installation codes for any special requirements.
Do not thread a cap or plug into a relief valve or relief valve line under any circumstances! Explosion and
property damage, serious injury, or death may result.
D. Scalding
An ASSE 1017 or ASSE 1070 temperature limiting or mixing valve is recommended in installations servicing
disabled or elderly persons, or children. Mixing valves do not eliminate the risk of scalding.
To avoid scalding:
• Set the water heater set point temperature as low as possible.
• Feel water before bathing or showering.
• If thermostatic valves are required, use devices specifically designed for such purpose. Install these devices
in accordance with instructions provided by the manufacturer.
Failure to install a temperature limiting or mixing valve and follow these instructions could result in property
damage, severe personal injury, or death due to scalds.
This water heater can deliver scalding water. Be careful whenever using hot water to avoid scalding injury. Certain
appliances such as dishwashers and automatic clothes washers may require increased water temperatures. By
setting the thermostat on this heater to obtain the increased water temperature required by these appliances
you may create the potential for scald injury.
To protect against injury, install a mixing valve in the water system. This valve will reduce point of use discharge
temperatures by mixing cold and hot water in branch supply lines. Such valves are available from your local
plumbing supplier.
