15. GENERAL SAFETY INFORMATION
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: www.amtrol.com/

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 boiler 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 feed boiler water directly through
the coil as 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.
