Amtrol WH-9 Classic Series, Top Down, RTR General Safety Information, Explosion or Rupture Hazard

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/ prop65

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 forth­ 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.
