The BCS vent is a chamber within a chamber. Heated flue gas is exhausted through an inner chamber, while cool outside air is pulled in through a surrounding outer chamber. This allows outside air to be preheated prior to combustion, while providing a cool outer surface for mounting through combustible materials. Available for oil or gas configurations.

          Standard length BCS vent (30-1/2") for wall thickness up to 8" (optional 30-9/16" length for wall thickness up to 12").

         Circumferential combustion clearance - 1/2" minimum Direct side wall venting - eliminates noxious fumes and odors. BCS unit allows outside air to be preheated before entering chamber - provides more efficient combustion. Carlin EZ-BCS burner - complete with air-boot. Available for oil or gas configurations.

         Turboflue® - Bock's patented design is the industry's most advanced and efficient heat exchanger. Simply put, it heats water faster and uses less fuel, which reduces energy costs.

          ®- Durable and exclusive porcelain enamel glass is used to line all tanks and Turboflues. Highly resistant to aggressive water. Fresh silica mixed daily to provide the highest quality.

• All stainless steel venting.
• Built to last - Hand-crafted from heavy gauge steel. Longer life equals a higher "Return on Investment".
• Dual magnesium anode rods - Inhibit corrosion and maximize tank life. Electrolysis attacks the anode rods, not the welded seams of the tank.
• Double pressure tested - Only Bock pressure tests its tanks twice.
• Fully welded tank skirt - prevents noxious flue gases from escaping between the tank and jacket.
• Center flue design - reduces tank flex for longer life.
• Fiberglass insulation - decreases standby heat loss.
• Accurate temperature control - Only Bock offers dual aquastats or operating and high limits, as standard.
• Spring loaded inspection door - Easy access for inspection and maintenance, also functions as a pressure relief valve.
• Brass drain valve - Accessible, tamper-proof.
• Factory installed T&P valve - CSA listed.
• Dielectric unions on boiler connections.
• Hand-cast refractory lined combustion chamber - Only one in the industry - better heat retention, warmer starts. better combustion, reduces noxious emissions.
• UL Listed.
• 5 year limited warranty - on steel tank (single family residential installations).
• 3 year limited warranty - on steel tank (commercial installations).
