AIR-FLAPPER
•A stainless steel air flapper is used inside the premix system to replace externally mounted flue damper to minimize the standby heat loss and to minimize the overall heater height
METAL VENTING
•Rated Category I Appliance. Uses standard double wall type “B” vent
•Can be commonly vented with other Category I appliances
•Vent connects directly to the vent connector outlet
•An excellent choice for retrofit and upgrade installations
•When common venting multiple BTL water heaters into a common vent system, follow the common vent tables in the current edition of the National Fuel Gas Code book for Category 1, Fan assisted heaters.
