What Is a Pizza Oven Flue Kit?
A pizza oven flue kit is a complete set of chimney components designed to vent smoke and gases from a wood-fired or multi-fuel pizza oven. These kits help control airflow, improve combustion, and prevent smoke from lingering in your cooking area.
A high-quality flue system ensures:
- Proper draft (airflow to fuel combustion)
- Removal of smoke, carbon monoxide, and moisture
- Consistent oven performance and heat retention
- Safe operation for users and surrounding structures
Why a Proper Flue System Is Critical
An improperly installed or poor-quality flue can cause:
- Smoke backflow into your oven or living space
- Difficulty maintaining high cooking temperatures
- Carbon monoxide risks
- Creosote buildup and chimney fires
- Non-compliance with Australian building codes
With a professional flue kit from Stainlessflue AU, you avoid these issues and enjoy seamless performance and safety.

Here’s what a typical Stainlessflue AU pizza oven flue kit includes:
| Component | Purpose |
|---|---|
| Flue Pipe Sections | Carries smoke away from oven |
| Base Support or Adapter | Connects flue to oven dome |
| Chimney Cap or Cowl | Prevents rain, debris, and downdraft |

Choosing the Right Flue Kit Size
Choosing the correct diameter and height of your flue is crucial for performance:
Diameter Guidelines:
- Small ovens (600–800mm): 125mm flue
- Medium ovens (800–1000mm): 150mm flue
- Large or commercial ovens: 200mm+
Height Guidelines:
- Outdoor ovens: Minimum 1.2m
- Indoor ovens: 1m above roof penetration
- Windy areas: Consider extensions for better draft
Our team at Stainlessflue AU can help you calculate the correct dimensions based on your oven and location.
