Chicago, IL -- November 25, 1996 -- ITT McDonnell
& Miller introduces the GuardDogRB-24, its new low water cut-off for
residential hot water gas-fired boilers. Model RB-24 is a conductance-type
water detection control designed for protection of residential gas-fired
hot water heating boilers against a loss of water condition. In the event
of a major loss of water, which could result in a fire or explosion of the
boiler, the unit will automatically shut the burner down.The new cut-off is in compliance with the International Mechanical Code 1996 which states that all steam and hot water boilers shall be protected with low water cut-off control. This is necessary because no other device, not even an automatic feed valve, can accurately detect a low water condition. Manufacturers also strongly suggest installation of low water cut-offs as part of every hot water boiler installation when the boiler is located above the radiation level.
The RB-24 features a compact high-temperature injection-molded plastic housing, which includes completely self-contained and sealed electronic water detection circuitry, to allow the unit to be mounted directly in the boiler. If necessary, the unit can also be mounted just above the boiler.
The RB-24's small size, easy installation
and simplified wiring were developed especially for use on residential hot
water boilers. This unit's single 24-volt model, which fits all residential
gas boilers, simplifies the selection for contractors and stocking for wholesalers.
Easy-to-read indicators and automatic reset after a power outage make the
unit simple for homeowners to use. A GuardDog RB-120 unit is also available
for use with oil-fired boilers.For more information about GuardDog low water cut-offs or any of ITT McDonnell & Miller's product lines, call 773/267-1600 or write to ITT McDonnell & Miller, 3500 N. Spaulding Avenue, Chicago, IL 60618. Website http://fhs.ittind.com
