Description: The Polaris, which operates at a cost-saving thermal efficiency of up to 96 percent, easily installs and pairs with recirculating systems or domestic space heating systems. Available in 34- and 50-gallon models, Polaris achieves energy efficiency through an enhanced, ultra-low NOx modulating gas burner that ensures operation at low input rates and maintains years of reliability with a durable tank and heat exchanger built of corrosion-resistant stainless steel. Compatible with both natural gas and propane, the Polaris features a power direct vent design that fits with polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), or polypropylene (solid core only) through a sidewall or roof. The Polaris can also be paired with an optional concentric vent kit.
