Description

Hobart 721027-1 36" Thermopile is a high quality designed for use in commercial cooking appliances, such as fryers and boilers. This thermopile operates at 250 to 750 mV and is very efficient at converting thermal energy to electrical energy to provide reliable ignition and consistent flame in equipment such as the Robertshaw 1950-53B, Cecilware fryers, Cleveland boiler gas steam generators, and other models of Imperial, Keating, Southbend, Star, Tri-Star, Vulcan, Wells, and Wolf. The thermopile's dual lead configuration lends itself to easy installation. This also maintains consistency in performance at its better even in the most extreme kitchen environments thanks to its durability and reliability resulting.

Step1: Shut off gas and electrical supply, then let burner assembly cool fully before handling.

Step2: Remove access cover and disconnect existing thermopile from pilot bracket and control valve terminals.

Step3: Install new thermopile, positioning tip directly in steady pilot flame for accurate millivolt generation.

Step4: Reconnect the leads securely to the gas valve.

Step5: Restore gas, light pilot, and confirm stable flame and ignition response.

Step6: Check all connections for leaks and secure panels before operation.

  • What maintenance is required for the Hobart 721027-1 Thermopile?

    Inspect the thermopile tip regularly for carbon buildup or soot and clean it gently to ensure proper flame contact and stable millivolt output. Check all electrical connections for tightness, corrosion, or heat damage. Verify correct pilot flame engulfment for accurate energy conversion. Replace if output becomes inconsistent or falls below operating range.

  • What are common issues with the Hobart 721027-1 Thermopile?

    • Weak or no millivolt output due to worn thermopile.
    • Pilot flame not properly heating sensor tip.
    • Carbon buildup reducing electrical generation efficiency.
    • Loose or corroded wire connections causing signal loss.
    • Intermittent burner operation from insufficient voltage output.
