The Model RB-24E Low Water Cut-Off is specifically designed to provide burner cut-off if there is an unsafe water loss, which can result from a broken or leaking radiator or pipe, or a cracked section in the boiler. McDonnell & Miller’s patented self-cleaning probe minimizes scale build-up and extends the recommended cleaning interval to 5 years. Water/glycol mixtures up to 50% concentration may be used.

Features

The RB-24E low water cut-off offers several features:

• Brass threads provide a metal-to-metal seal that ensures a leak-free installation
• Integrated wrench flats enable secure installation without damage to the housing
• “Plug & Play” wiring harnesses are available for most residential gas-burning boilers
