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 HAZARD TO THEM 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.
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
SCALDING HAZARD: A CHECK VALVE MUST BE INSTALLED IN THE BOILER RETURN LINE TO PREVENT GRAVITY FLOW THROUGH THE HEAT EXCHANGER. THIS CAN CAUSE OVER HEATING AND RESULT IN SERIOUS SCALDING.

MODELS. Glycol is a hazardous substance. To avoid seepage or leakage of glycol to surfaces where children or animals can ingest it, use glycol only in double-walled units, so that any leaks will most likely be released to the atmosphere. However, a leak to a surface area may still occur, so any use of glycol must be monitored closely and children and animals should be protected from contact with the unit.

BOILER MATE™ will be supplied before space heating.
In limited cir
heating can be lost in the home in this priority mode. Any demand for space heating is postponed until the BOILER MATE™ has reached its set temperatur 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.
Select Circulator versus Zone Valve
j
The flow of hot boiler water to the BOILER MATE™ can be controlled with either a motorized zone valve or a circulator.
1. Zone valve (system flow of 4-8 gpm). If a zone valve is to
be used, a minimum flow rate of 4 gpm with all zones in use is required with a maximum of 8 gpm with only the BOILER MATE™ in use. Be sure the zone valve chosen has a maximum pressure drop (Cv = 4) when fully opened.
2. Separate circulator. The recommended way to provide
adequate flow through the BOILER MATE™ heat exchanger is to use a separate dedicated circulator with a minimum flow rate of 4 gpm (10 feet of head minimum) and maximum flow rate of 8 gpm. This option may be used even though the heating system utilizes zone valves.

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®expansion tank and the boiler temperatures are being changed, resize the EXTROL®expansion tank.

A. General Installation Requirements
1. Do not "short circuit" the boiler
Do not connect boiler supply and return lines to the same section or in the same flow circuit in a boiler, because the boiler water returning from the BOILER MATE™ will "short circuit" and exit the boiler too cold for proper heat transfer.
2. Avoid high flow domestic water recirculating loops
If a recirculating loop is necessary consult applicable Code requirements. A flow of no more than 1/2 gpm is all that is generally needed for temperature maintenance at the furthest hot water fixture. Any flow greater than 1/2 gpm will result in excessive heat loss and reduction in performance.
3. Locating Unit
Do not locate this product where leaking and flooding could cause
damage to surrounding property.
The BOILER MATE™ should be located in an area where water leakage from the tank or connections will not result in damage to areas adjacent to the application or to lower floors of the structure. When such a location cannot be avoided, a suitable drain pan must be installed. The pan must be connected to a drain. The installation location for this unit should also be chosen to comply with the follow­ing required and recommended dimensions for clearance and accessibility:
Clearance from Combustible Surfaces This unit is design certified by the C.S.A. for installation on combustible flooring and in alcoves, closets, etc. The min­imum clearance dimensions from combustible material is as follows: (See dimensions given facing units)
Clearance From Combustible Surfaces

4. Instructions for reversing unit:
The unit is designed to be reversible, i.e. depending on the particular installation area, the BOILER MATE™ can be rotated 180° for easier connection to the boiler and cold water supply. All units are shipped "left-handed" with all connections (boiler, cold water supply) on the left side of the unit. If, for ease of installation, it is necessary to have the connections on the right, the following steps should be taken:
1. Carefully remove the front panel (remove top screw and unhook from stand).
2. Move the access panel/electronic control assem­bly to the opposite side of the BOILER MATE™.
3. Remove the ground screw from the BOILER MATE™ stand and save.
4. Proceed with electrical installation
5. Reassemble the access panel/electronic control to
the BOILER MATE™.
6. Confirm that the temperature sensor is firmly inserted into the thermostat well.
7. Proceed with the installation.

AND LOW PRESSURE STEAM BOILER.
The BOILER MATE™ is intended to provide a tank service life of many years. Components, however that require service. Failure to use the correct procedures or parts in these circumstances may make the unit unsafe.
• DO NOT OPEN DOWN-STREAM FIXTURE IF YOU HAVE LOOSENED THE TOP CONNECTIONS.
• DO NOT OVER-DRAIN THE TANK - THE HEAT EXCHANGER MUST REMAIN COVERED BY WATER TO AVOID DAMAGE TO THE LINER.

c. T & P Relief Valve - Yearly Inspection
d. Sediment - Monthly Inspection - depending on water
conditions Depending on water conditions, a varying amount of sediment may collect in the tank. This is normal. Levels requiring service are indicated by a small temperature difference in the supply and return lines. (See also "Scale" below.) Repeated flushing usually clears such material. As a preventive measure, each month water should be drawn from the tank at the drain valve until it runs clear.
e. Scale - Monthly Inspection
A small temperature difference between the water entering and leaving the coil may indicate a scale build-up. A water softener will prevent this problem. (See also "Sediment" above.) Repeated flushing should also resolve the problem. If not, proceed as follows:
