Lochinvar & A.O. Smith 100187863 Elbow
The Lochinvar & A.O. Smith 100187863 is a 4-inch aluminum exhaust/condensate elbow assembly engineered specifically for high-efficiency gas-fired boilers and water heaters. As a veteran technician knows, managing flue gases and acidic condensate in condensing systems requires components that can withstand corrosive environments without compromising structural integrity. This OEM replacement part is constructed from high-grade aluminum, offering superior corrosion resistance compared to standard galvanized fittings while keeping the assembly lightweight for easier overhead installation. It ensures a smooth exhaust flow with minimal back pressure, crucial for maintaining the precise combustion ratios required by modern modulating condensing boilers. Designed as a direct-fit component, this 4" elbow facilitates the critical transition between the heat exchanger and the venting system, incorporating a profile that effectively manages condensate drainage back toward the trap, preventing liquid accumulation in the blower or burner assembly.
Key Benefits
- Optimized Flow Dynamics: Reduces back pressure to maintain peak blower efficiency and stable flame signals.
- High Corrosion Resistance: Aluminum construction is designed to handle the acidic nature of flue gas condensate common in high-efficiency systems.
- Precision OEM Fitment: Eliminates the need for field-fabricated adapters, ensuring a leak-free seal on 4-inch venting outlets.
- Thermal Stability: Engineered to withstand the fluctuating temperatures of discharge gases without warping or degrading.
- Integrated Condensate Management: Geometric design supports proper pitch to ensure condensate moves away from critical electronic components.
Common Questions
Is this elbow compatible with PVC or CPVC venting systems?
This 100187863 aluminum elbow is typically used for the internal transitions within the appliance or specifically approved aluminum vent runs. For field-installed venting, always refer to the specific boiler or water heater manual to verify the approved materials (PVC, CPVC, or Stainless Steel) for the exhaust run.
Can this part be used for both the intake and exhaust sides?
While sized at 4 inches, this component is specifically listed as an exhaust/condensate elbow. Using it on the intake side is generally acceptable if the dimensions match, but its primary engineering focus is on the harsher conditions of the exhaust stream.
How do I ensure a gas-tight seal during installation?
Ensure all mating surfaces are clean of debris. When installing this HVAC replacement part, verify the orientation allows for the natural flow of condensate toward the drain points to prevent "slugging" or premature component failure.
