<h3>About Suburban Manufacturing</h3><p><strong>Suburban Manufacturing</strong> has been a cornerstone of the RV industry for over 75 years. <a href="/7593-suburban-mfg">Suburban Mfg</a> traces its roots back to 1947, when it began as the Hunt Heater Company, producing small gas space heaters in Dayton, Tennessee. A pivotal moment came when a customer asked whether one of Suburban's greenhouse heaters could be adapted to run on 12V for use in a motorhome — and the RV-focused legacy of the brand was born. Today, Suburban is headquartered in the same Dayton, Tennessee community it has called home for decades, operating out of a facility that spans more than 300,000 square feet.</p><p>In 1998, Suburban joined the <strong>Airxcel</strong> family of brands, which has grown into the leading designer, manufacturer, and distributor of critically functional products for the RV industry. That partnership gave Suburban the resources to continuously refine and expand its product line while maintaining the hands-on manufacturing quality that built its reputation. Suburban's engineers have pioneered a long list of RV industry firsts — from space-saving, horizontally vented gas heating systems and solid-state spark ignition technology to efficient DC furnace motors and glass-top ranges that double as counter space when not in use.</p><h3>What Suburban Makes</h3><p>Suburban's core product lineup covers the essential comfort systems that RV travelers depend on every day. The brand is perhaps best known for its <a href="/7593-suburban-mfg-heating-200526">RV heating solutions</a>, including a comprehensive range of ducted furnaces and wall heaters engineered specifically for the space constraints and power demands of motorhomes and travel trailers. Suburban furnaces are designed to deliver reliable warmth using propane, with efficient DC blower motors that minimize battery draw — a critical factor for off-grid campers.</p><p>Beyond heating, Suburban has long been a trusted name in RV kitchen appliances. Their <a href="/7593-suburban-mfg-stoves-cooktops-201021">stoves and cooktops</a> are built with the unique requirements of RV galleys in mind: compact dimensions, durable construction, and propane-compatible burners that perform reliably on the road. Suburban has also expanded into <a href="/7593-suburban-mfg-stoves-cooktops-202596">outdoor cooking</a>, offering cooktops and cooking appliances designed for the camp kitchen experience outside the coach — including griddles and other galley accessories inspired by contemporary European design and manufactured in America.</p><p>Most of Suburban's product line is backed by a <strong>2-year limited warranty</strong>, reflecting the brand's confidence in its own manufacturing standards. Each product goes through a rigorous series of quality and safety tests before leaving the Dayton facility — a commitment that has made Suburban a preferred OEM supplier for many of the largest RV manufacturers in North America.</p><h3>A Legacy of Innovation</h3><p>Suburban's influence on modern RV design is difficult to overstate. The company helped pioneer the glass-top range, which transformed compact galley kitchens by providing valuable counter space when burners aren't in use. More recently, Suburban has pushed into all-in-one solutions: their <em>RV One</em> system combines an on-demand water heater and NT furnace into a single unit engineered for the growing segment of compact and lightweight travel trailers. With a track record of listening closely to the needs of RV builders and end users alike, Suburban continues to set the standard for what RV appliances can be.</p>

Product Details

The Suburban Mfg 523015 Low Capacity Automatic Changeover Regulator is a single-stage LP propane regulator designed to deliver uninterrupted gas flow to RV appliances. It automatically switches from an empty service cylinder to a full reserve cylinder, eliminating the need for manual intervention and ensuring your appliances keep running without disruption.

A highly visible full/empty indicator clearly signals when a cylinder needs to be refilled, and the built-in back check valve allows the empty cylinder to be safely removed and refilled while the reserve cylinder remains in active service. An Overpressure Protection Device (OPD) limits environmental propane release to less than 2 PSI in the event of a regulator malfunction — well below the threshold mandated by UL Standard 144.

Key Features:

  • Automatically switches from empty service cylinder to full reserve cylinder
  • Ensures continuous, uninterrupted LP gas flow to appliances
  • Highly visible full/empty indicator signals when refill is needed
  • Built-in back check valve allows cylinder swap while reserve remains active
  • Overpressure Protection Device (OPD) limits release to less than 2 PSI
  • Flow limiter reduces gas flow in the event of hose rupture or accidental disconnection
  • Adjustable outlet pressure setting
  • Rated at 160,000 BTU/hour
  • Dual inlets: Two 1/4 in. inverted flare
  • Outlet: 3/8 in. female pipe thread (FNPT)
  • Includes mounting bracket and protective plastic cap cover
  • UL listed
  • Approved for RV use

Suburban Manufacturing is a leading supplier of LP gas accessories for the RV industry, known for reliable performance and quality construction. The 523015 automatic changeover regulator is an essential component for dual-cylinder propane setups in motorhomes, travel trailers, and fifth wheels.
