Double wall class A installation
A Class A chimney system must be selected to suit the appliance and building configuration. Where the chimney runs along an exterior wall, the installation requires appropriate wall-pass-through components, supports and roof clearances.
Chimney Experts Cleaning & Repair provides chimney installation services in New York, assessing the proposed route and system requirements before discussing suitable components.
Wall Pass Through Placement
Placement is an important consideration when planning a through-wall chimney system. The wall opening affects the route, connector lengths and position of the exterior chimney.
For chimney pipe installation, our team reviews the appliance location, nearby surfaces and the selected system’s instructions. Required clearances depend on the specific appliance and components rather than a single measurement for every installation.
Wall Thickness & Type
Wall thickness and construction help determine the appropriate pass-through components. The installation must account for the materials within the wall and the requirements of the selected chimney system.
When assessing a double wall chimney, our team also considers the exterior siding and weather protection around the opening. Components are selected for compatibility with the system and property.
Exterior Supports
Exterior chimney sections require suitable support and stabilization. The support arrangement depends on the system, chimney height and available attachment points.
Our team assesses the wall structure and proposed route before planning the installation. Support spacing and permitted loads must follow the selected product’s instructions.
Eave Overhang & Offsets
Exterior chimney sections require suitable support and stabilization. The support arrangement depends on the system, chimney height and available attachment points.
Our team assesses the wall structure and proposed route before planning the installation. Support spacing and permitted loads must follow the selected product’s instructions.
Roof Clearance
The chimney termination must meet the requirements applicable to the appliance, chimney system and building. Roof shape, nearby structures and the height of exposed pipe all affect installation planning.
Our team assesses the required termination position and any additional bracing needed. The final arrangement must follow the selected system’s instructions and applicable local requirements.
Measuring Form and Parts List
Accurate measurements help identify the components required for a Class A chimney installation. Our team reviews the appliance connection, wall construction, exterior route, support locations and roof position.

Frequently Asked Questions
What is a Class A chimney?
A Class A chimney is a factory-built chimney system intended for compatible appliances. The appropriate product depends on the appliance, fuel and installation requirements.
Is double wall stovepipe the same as a Class A chimney?
No. Appliance connector pipe and factory-built chimney sections serve different purposes. A double wall description alone does not establish that a product is suitable for passing through a wall or roof.
Can a chimney system run through an exterior wall?
A through-wall arrangement may be suitable when permitted by the appliance and chimney system. It requires compatible pass-through components, supports and an appropriate exterior route.
Can you extend an existing chimney system?
The existing system must first be identified and assessed. Any extension components need to be compatible, and the proposed arrangement must meet the system’s requirements. A chimney inspection can help assess the existing system before an extension is planned.
What affects the cost of chimney installation?
Cost depends on the appliance, route, chimney height, wall or roof construction, supports and access. An assessment helps establish the work and components required.
