Proylite 3100 Chamber Wall - Retains heat ensuring cool operation and maximum heat transfer to water, not the room. 3. Heat Distribution/Flame Deflector Dome - Distributes heat evenly throughout combustion chamber and flues, eliminating hot spots and uneven heat transfer, resulting in peak operating efficiency and heater life. 4. Flame Spreader - Acts like a spray nozzle to distribute flame in combustion chamber. Helps eliminate hot spots and uneven heat transfer. 5. Sealed Combustion Chamber Commercial Water Heaters: BT 65, 80, 100 BTP D, 540A, 700A BTR 120-500A Master-Fit® Residential Water Heaters: ProMax Conservationist Energy Saver
