An adjustable duct coupling and deformable gasket let one venting assembly fit varied water heater duct layouts while enabling flue gas checks.

By integrating the combustion air duct into the wall plate, this case cuts wall clearance, hides the duct, and cools the plate during stove operation.

A wall bracket and movable blanking plate let a coaxial flue connect from the rear without opening the heater housing.

An internal liquid collector and flow-guiding flue remove condensate before discharge, cutting visible boiler pluming without sacrificing condensing efficiency.

See how three chimney stages combine an integrated fireplace body with screw-anchored upper support for modular assembly.

Vertically arranged side flues and segmented dampers create controllable flow paths that help prevent ash buildup and condensation.

Conventional chimneys release combustion heat; nested inner and outer stacks transfer it to incoming air to improve appliance efficiency.

A closure member seals the central combustion duct while leaving the peripheral oxidizer path open.

An elongated closure element seals inner and outer pipe openings, preventing exhaust gas leaks into installation rooms.

A flue damper float lifts the gate to drain accumulated condensate from the pipe.

Helical water separation wall diverts precipitation, preventing flue gas recirculation without increasing roof passage height.

A flue damper uses a drainage port to remove condensate, preventing gate blockage and equipment failure.

Segmented air duct captures exhaust leaks via negative pressure and discharges gases through a positive pressure section, preventing interior contamination.

Height-adjustable air inlet connectors accommodate non-standardized fireplace positions without requiring precise pre-installation measurements.

Double wall tubular flue gas outlet assembly uses a locking member to enable longitudinal length adjustment.

A flexible chimney pipe installation tool establishes mechanical connections between exhaust stack segments using magnetic attraction and tensioning mechanisms.

Movable backflow barriers control gas direction in shared exhaust and air supply systems, preventing hot gas backflow to non-operated burners.

A gas exchange termination assembly maintains neutral pressure using angled intake openings and exhaust slots to direct combustion flow.
