Unique to today’s market, Direct-Temp provides exceptional corrosion protection (and virtually no leakage) due to an inner stainless-steel liner. Stainless steel permits precision manufacturing tolerance, ensuring tight seals and the added structural integrity of the system. The liner has a continuously welded seam, which is superior to lock-seam designs that might leak. The company’s engineers set out to surpass the performance requirements of the industry using unique features found only in the company’s direct-vent system. Direct-Temp is ideal for both sidewall and conventional through-the-roof venting solutions and has been engineered for optimum appliance performance.
