Product Description

Superior DRL3555 55" overview

The DRL3555 is the largest model in Superior's Pro Series DRL3500 line and is notable for its low profile: it frames at only 29" tall and 18" deep, so it fits under windows, into low knee walls or beneath a large TV without eating up wall height.

Despite the value positioning it is well equipped: battery-backed IPI/CPI ignition, platinum crushed glass, tempered glass, a factory blower with six speeds, floor lighting with six settings and a multi-function remote with thermostat. A black porcelain liner can replace the painted interior, and the HeatFlo kit is available on this 55" size.
