COMPONENTS CHECKLIST

The following is a checklist of components required for proper installation of these

BOILER MATE™ models, both Priority and Non-Priority:

A. Separate circulator

• 1 each - circulator (4-8 gpm)
• 1 each - positive shut-off weighted check valve

B. Use of heating system zone circulator

• 1 each - zone valve

C. Also Required:

• 4 each - unions
• 4 each - shut off valve
• 1 each - vacuum breaker
• 1 each - T & P relief valve (included)
• 1 each - A THERM-X-TROL

expansion tank - REQUIRED IF a Back flow preventer, check

valve or pressure reducing valve is installed anywhere between the BOILER MATE™ and
the city main.

• As needed - pipe dope or Teflon tape
• Do not forget an EXTROL

and thermal expansion - an expansion tank is required on the boiler

side of your system.

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.
