The Rheem Commercial Universal Gas Water Heaters are engineered for compact retrofit installations while delivering robust performance to meet demanding commercial needs. With a 100-gallon tank and a powerful 199,900 BTU natural gas burner ignited by a quick spark-to-pilot electrical system, this unit offers versatility and efficiency. Its compact footprint, low vent height, and multiple water connections facilitate seamless replacement, ideal for various hot water applications. However, it's essential to note that a 120-Volt power source is required for operation. Notably, for residents in California, Utah (effective 7/1/18), and Texas, compliance with emissions regulations is crucial, as outlined. The space-saving design, coupled with features like the System Sentinel LED diagnostic system and stainless steel burners, ensures reliability and easy maintenance. Additionally, built-in corrosion resistance and fully insulated construction enhance longevity and energy efficiency. Furthermore, the gas control system provides precise temperature adjustment and safety features. For tailored configurations, Rheem's universal line offers water heaters ranging from 35 to 100 gallons, available in various BTU/h ratings for both natural gas and liquid propane options.
