The Gravity Wall Furnace with PilotPro comes with all of the quality and reliable features of Cozy's Gravity Wall Furnace, now with all the benefits of PilotPro, the gas-heating industry's first battery-ignition pilot system. With the inclusion of Cozy's innovative, patent-pending PilotPro technology, the pilot light is lit only when needed, increasing the furnace's energy efficiency by as much as 2%. This also leads to an average cost savings of $75 per year on gas bills. In the event of a pilot outage, PilotPro relights the pilot on demand, eliminating the need for manual relighting or emergency contractor calls. Requiring only 2 D batteries to operate, the batteries can be easily replaced by removing the cover, no tools required. Cozy Gravity Wall Furnaces mount on any inside or outside wall (single wall only), providing both circulated and radiant heat in an economical package. Available in single or dual wall models, each fits between any standard 16 in. center stud space. With 25,000 and 35,000 BTU options, Cozy Gravity Wall Furnaces provide ample heating for new constructions, additions and other hard-to-heat areas. Equipped with self-energizing controls for use during power outages, heavy-gauge steel grill to eliminate heat warp and an optional fan accessory kit, Cozy Gravity Wall Furnaces are a top choice of contractors everywhere.
