Designed for Long Life

Its robust stainless steel heat exchanger is durably constructed with an oval pipe design for maximized heat transfer and long life. The oval design creates less scale build-up, increased thermal efficiency and lower maintenance.  The unique design boasts an increased life cycle of 3.5 times more than a copper heat exchanger.  

The LT Series has burner control and a combusion system that is designed for longer life, reduced dust build-up and fewer maintenance issues.  This combusion system includes a negative pressure gas valve and metal fiber construction.
