General Features NATURAL GAS MODELS Central Heating furnace designs are certified by the American Gas Association for both natural and L.P. gas. Limit setting and rating data were established and approved under standard rating conditions using American National Standards Institute standards. SAFE OPERATION The Integrated System Control is a solid state device which continuously monitors for presence of flame when the system is in the heating mode of operation.
Features and Benefits 96.
Features and Benefits THREE–WAY MULTI-POISE (UPFLOW, HORIZONTAL LEFT AND RIGHT) PLUS DEDICATED DOWNFLOW Easier to specify Shipped ready to install (no kits required) Every model has at least two venting options When in horizontal, trap extends only about 2” Barbed fitting on trap at hose connection and on cabinet transition for hose has barbed fitting and clamps at both ends for leak resistance.
