10. GENERAL SAFETY INFORMATION
-13-
SCALDING HAZARD. If the water
temperature is over 120°F, household
members can suffer serious or fatal scalding and painful and
permanent injury. • The Consumer Products Safety Commission
recommends an initial setting of 120°F, but notes a slower
response time of infants, aged, disabled and other persons
increases the scalding hazard and may require lower settings. •
Always check the water temperature before use, including washing,
bathing or showering. • Temperature limiting valves are available
from your plumbing supplier. A check valve must be installed in the
boiler return line to prevent gravity flow through the heat exchanger.
This can cause overheating and result in serious or fatal scalding.
SCALDING HAZARD. If the thermostat is
not working properly or if this product is not
installed in accordance with the manual, water temperature can
reach excessive levels that may cause serious or fatal scalding.
After installation and any servicing of the unit, verify that the
thermostat is working and firmly inserted in the thermostat well by
following the thermostat testing instructions in the manual.
Failure to use the correct replacement
parts may make your product unsafe.
CALIFORNIA PROPOSITION 65
WARNING! WARNING: This product
contains a chemical known by the State of California to cause
cancer and birth defects or other reproductive harm. (California
Installer/Contractor - California law requires that this notice be
given to consumer/end user of this product.) For more information:

In limited circumstances, space heating
can be lost in the home with unit utilizing
priority mode. Any demand for space heating is postponed until
the Boiler Mate
®
has reached its set temperature. This delay in
supplying the space heating zones is usually not noticed by the
inhabitants of the living spaces. However, in the event of certain
malfunctions such as circulator or thermostat failure, space
heating could be delayed indefinitely. If undetected and
uncorrected, freezing damage to piping could result.
If a steel hydropneumatic tank is in place,
AMTROL
®
recommends replacing it with
a properly sized EXTROL
®
expansion tank. Otherwise, significant
heat transfer problems can occur by causing air to be trapped in
the heat exchanger. If the boiler system has an EXTROL
®
or
Radiant EXTROL
®
expansion tank and the boiler temperatures are
being changed, resize the EXTROL
®
or Radiant EXTROL
®
expansion tank.
If installing on city water supply a properly
sized THERM-X-TROL
®
is required with
the BoilerMate
®
and should be installed as set fo rth in the
THERM-X-TROL
®
product installation manual. Contact your water
supplier or local plumbing inspector for additional information.
Prevent pressure build-up in any existing
internal tankless coil. Do not plug incoming
or outgoing tappings in the internal tankless coil plate. Leave the
coil in the boiler and leave system connections open, to prevent
pressure build-up.
Electrocution Hazard. The BoilerMate
®
must be electrically grounded. Electrical
supply must come from the boiler side of boiler’s emergency
shut-off switch in order to prevent unsafe operation.
Chlorine Aggressive Water: The water
quality can significantly influence the life
of this Product. You should test for corrosive elements, acidity,
total solids and other relevant contaminants, including chlorine and
treat your water appropriately to insure satisfactory performance
and prevent premature failure.
Note: Inspect for shipping damage and notify freight carrier or
store where purchased immediately if damage present. To avoid
risk of personal injury and property damage, if the product appears
to be malfunctioning or shows signs of corrosion, call a qualified
professional immediately. Current copies of the Product manual
can be viewed at www.amtrol.com. Use proper safety equipment
when installing.
EXPLOSION HAZARD. The pressure of
the heat transfer medium must be limited to
a maximum of 30 psig by an approved safety or relief valve on your
boiler. The BoilerMate
®
pressure must be limited to 150 psig
maximum by the installation of a temperature and pressure relief
valve (included). The relief tube must be plumbed to a suitable
drain per code. No reducing coupling or other restriction may be
placed in this line.
This Product, like most Products under
pressure, may over time corrode, weaken
and burst or explode, causing serious or fatal injury, leaking or
flooding and/or property damage. To minimize risk, a licensed
professional must install and periodically inspect and service the
Product. A drip pan connected to an adequate drain must be
installed if leaking or flooding could cause property damage. Do
not locate in an area where leaking could cause property damage.
EXPLOSION OR RUPTURE HAZARD. A
relief valve must be installed to prevent
pressure in excess of local code requirement or maximum working
pressure designated in the Product Manual, whichever is less. Do
not expose Product to freezing temperatures or temperatures in
excess of the maximum rated operating temperature.
If not installed by the boiler manufacturer,
install a low water cut-off or pressure
reducing valve on your boiler so that leaking will not result in a dry
boiler which if the boiler continues to fire, will cause an explosion
hazard.
This unit must be installed as a separate
heating zone. Do not connect this unit to
an existing heating zone or dangerous over-heating will result.
Do not drain this appliance before shutting
off the supply valve and opening the relief
valve or another downstream fixture, as it will damage this unit. A
vacuum breaker should be installed to avoid damaging the liner.
Damage to the unit and leakage can occur if a vacuum breaker is
not installed.
USE GLYCOL ONLY WITH
DOUBLE-WALLED HEAT EXCHANGER
MODELS. Avoid risk of ingesting a toxic glycol fluid. The heat
transfer medium should be water. If glycol must be used, it should
only be used with double-walled heat exchangers and closely
moitored for leakage.
