Made with either two or three copper-sheathed tubular elements that are silver soldered to a threaded brass fitting
The fitting is installed through a 2-7/16” diameter hole in the bottom of the vessel, and secured to the vessel by a brass hex nut.
A NEMA 1 terminal box is standard on all units.
All standard bottom-mounted immersion heaters, with or without a low water cutout are UL listed.
Allen Head Fitting – For convenience of installation, an Allen head fitting can be furnished on a NEMA 1 outlet box. This allows installation with a 3/8” Allen wrench rather than the wide jaw wrench required to fit the large hex nut on the NEMA 1 box.
