Description
Its Direct Spark Ignition (DSI) system provides safe and easy startup without the need for a pilot light. The 1440-watt electric element and 12,000 BTU gas burner can operate separately or simultaneously for a fast recovery rate, meaning less waiting between uses.
Designed for dependability, the SW12DELC includes a replaceable anode rod for corrosion protection, a copolymer insulation jacket to retain heat efficiently, and a sturdy die-formed metal control housing to protect against weather and debris.
Please note: Access door and on/off switch sold separately.
