Custom Chimney Pipe Builds for Every Brand & Application | Smokey Mountain Fireplaces
Share
Venting is the part of a fireplace installation that most people don’t think about until it’s too late. We do. Here’s how Smokey Mountain Fireplaces supports your build — from specification to delivery — across every brand we carry and every application that needs a flue.
Why Chimney Pipe Specification Matters
A fireplace without a properly designed venting system is just a box. The chimney pipe is what makes the whole installation work — and getting it wrong means callbacks, failed inspections, and costly rework after walls are closed.
For designers and contractors, the challenge is that chimney pipe systems are highly specific to the fireplace model, the ceiling height, the roof pitch, the framing configuration, and local code requirements. There’s no universal kit. Every build is different.
What We Do: Custom Chimney Pipe Design
When you work with Smokey Mountain Fireplaces on a fireplace specification, we help you design the complete venting system — from the appliance collar to the roof cap — so your installation goes in clean the first time.
What we need from you:
- Fireplace or stove model
- Ceiling height and whether it’s flat or vaulted
- Roof pitch
- Desired flue exit point (straight up, offset, through a wall)
- Framing constraints or existing chase dimensions (for remodels)
- Application type — residential, commercial, outdoor kitchen, or specialty
What we provide:
- Complete parts list with quantities and SKUs
- Diameter and length specifications for each section
- Adapter and reducer callouts where diameters change
- Elbow configurations for offsets
- Ceiling support and roof termination components

Common Build Scenarios — With Diagrams
Scenario 1: New Construction — Straight Vertical Run (Flat Ceiling)
The most common residential configuration. Stove sits on the floor, flue runs straight up through a framed ceiling opening and exits at the roof.
┌──────────────────────────────────────┐ │ ☁ ROOF CAP (DuraTech) │ │ │ │ │ ████████████ ROOF FLASHING │ │ │ │ │ ──────────── ATTIC SPACE │ │ │ Class A Chimney Pipe │ │ │ (DuraTech — all-fuel) │ │ ──────────── CEILING PENETRATION │ │ │ Ceiling Support Box │ │ ──────────── LIVING SPACE │ │ │ DVL Sections │ │ │ (Double-Wall Black) │ │ │ DVL Adapter / Damper │ │ ┌─────────┐ STOVE / FIREPLACE │ │ │ STOVE │ │ │ └─────────┘ │ └──────────────────────────────────────┘
Key components: DVL Adapter → DVL Sections → Ceiling Support Box → Class A Chimney Pipe → Roof Flashing → Chimney Cap
Scenario 2: New Construction — Vaulted Ceiling with Offset
Common in A-frame, cabin, and open-plan builds. Requires elbows to navigate the slope and transition to a vertical Class A run.
┌──────────────────────────────────────┐ │ ☁ ROOF CAP │ │ │ Class A (vertical) │ │ ████████████ ROOF FLASHING │ │ │ │ │ 90° or 45° Elbow │ │ ╱ │ │ ╱ DVL Offset Section │ │ ╱ (follows vault angle) │ │ 45° Elbow │ │ │ │ │ DVL Adapter / Damper │ │ ┌─────────┐ STOVE │ │ │ STOVE │ │ │ └─────────┘ │ └──────────────────────────────────────┘
Key components: DVL Adapter → 45° Elbow → DVL Offset Section → 90° or 45° Elbow → Class A Chimney Pipe → Roof Flashing → Cap
Scenario 3: Remodel — Retrofit into Existing Masonry Chase
Inserting a new stove or insert into an existing masonry fireplace. The existing flue becomes the chase; a liner and adapter bridge the old and new systems.
┌──────────────────────────────────────┐ │ ☁ CHIMNEY CAP (existing masonry top) │ │ │ │ │ ████████████ MASONRY CHIMNEY │ │ │ Flexible Liner │ │ │ (sized to appliance) │ │ ──────────── FIREBOX OPENING │ │ │ DVL Adapter / Reducer │ │ │ (matches collar to liner) │ │ ┌─────────┐ INSERT / STOVE │ │ │INSERT │ │ │ └─────────┘ │ └──────────────────────────────────────┘
Key components: Insert/Stove → DVL Adapter/Reducer → Flexible Liner (through existing masonry) → Chimney Cap
Scenario 4: Malm Floating Cone — Ceiling-Hung Installation
Unique to Malm’s suspended cone design. The flue hangs from the ceiling rather than rising from the floor — requiring a different pipe configuration and ceiling attachment point.
┌──────────────────────────────────────┐ │ ☁ ROOF CAP │ │ │ Class A (through roof) │ │ ████████████ CEILING ATTACHMENT │ │ │ Malm Flue Pipe │ │ │ (24" + 12" sections) │ │ │ 45° or 90° Elbow (if offset)│ │ │ Malm Flue Pipe │ │ ▼ CONE COLLAR │ │ ╱─────────\ │ │ MALM │ (floating — no floor contact)│ │ \ CONE ╱ │ │ ╲─────╱ │ │ (suspended from ceiling flue) │ └──────────────────────────────────────┘
Key components: Malm Flue Pipe sections (12" & 24") → Elbows as needed → Ceiling attachment → Class A through roof → Cap
Scenario 5: Coffee Roasting Exhaust System
Drum roasters produce high-temperature smoke, chaff, and VOC exhaust that requires a properly rated, correctly sized flue. This is not a standard residential chimney pipe application — sizing depends on your roaster’s CFM output, exhaust collar diameter, and local commercial code.
┌──────────────────────────────────────┐ │ ☁ EXTERIOR TERMINATION CAP │ │ │ (spark arrestor recommended)│ │ ████████████ WALL / ROOF PENETRATION │ │ │ Class A or Stainless Liner │ │ │ (sized to roaster CFM) │ │ ──────────── ROASTERY / INTERIOR │ │ │ 90° Elbow (if wall exit) │ │ │ DVL or Stainless Sections │ │ │ Adapter (collar to flue) │ │ ┌─────────┐ DRUM ROASTER │ │ │ROASTER│ (exhaust collar size varies)│ │ └─────────┘ │ └──────────────────────────────────────┘
Key components: Roaster exhaust collar → Adapter → DVL or stainless sections → 90° Elbow (if wall exit) → Class A or stainless liner → Spark arrestor cap. Contact us with your roaster make, model, and exhaust collar size for a custom spec.
Scenario 6: Outdoor Pizza Oven / Covered Kitchen
Covered outdoor kitchen installations require proper exhaust routing to prevent smoke buildup under the structure. Cap type and clearances are critical.
┌──────────────────────────────────────┐ │ ☁ RAIN CAP (above pergola/roof) │ │ │ │ │ ████████████ PERGOLA / ROOF │ │ │ Class A or Single-Wall │ │ │ (clearance to structure) │ │ ──────────── OUTDOOR KITCHEN SPACE │ │ │ Flue Sections │ │ │ Adapter (oven to flue) │ │ ┌─────────┐ PIZZA OVEN │ │ │ OVEN │ (Gozney, CBO, Pinnacolo) │ │ └─────────┘ │ └──────────────────────────────────────┘
Key components: Oven exhaust collar → Adapter → Flue sections → Roof/pergola penetration → Rain cap with spark arrestor
