The Centrotherm ISAAL0303 is an InnoFlue SW Residential Appliance Adapter designed for use in single-wall residential venting systems. It is made from CPVC and PVC materials and connects a 3-inch appliance outlet to a 3-inch vent pipe. The adapter measures 3 inches in length and provides a secure, airtight transition between the appliance and the vent system. HVAC technicians and installers use this part when setting up or replacing venting on high-efficiency condensing appliances such as furnaces, boilers, and water heaters. The InnoFlue SW system from Centrotherm is a lightweight, corrosion-resistant alternative to stainless steel vent systems. CPVC and PVC construction makes this adapter well-suited for the acidic condensate that high-efficiency appliances produce. The material resists degradation from flue gases and moisture, which extends service life in demanding residential venting applications. This adapter is a critical connection point in any InnoFlue SW installation. It attaches directly to the appliance collar and transitions smoothly into the rest of the single-wall vent run. Proper fitting selection at the appliance connection prevents flue gas leaks, which is essential for safe and code-compliant installations. Contractors working on new construction or retrofit projects will find this part straightforward to install. It is compatible with the full InnoFlue SW product line, allowing seamless integration with elbows, couplings, and termination fittings in the same system. The ISAAL0303 is a reliable, professional-grade component that meets the demands of residential HVAC venting work.
The Centrotherm ISAAL0303 InnoFlue SW Residential Appliance Adapter delivers a durable, corrosion-resistant connection point for single-wall residential venting systems. Its CPVC and PVC construction is built to handle the condensate and flue gases produced by modern high-efficiency heating equipment.
