Integrated Pizza Oven Ventilation Systems​

Designed for seamless integration, code compliance, and reliable performance in commercial kitchen environments.

Marra Forni ovens feature an integrated vent above the oven mouth.

This system directs heat and exhaust to a dedicated flue connection for direct ventilation.

Our team works with architects, contractors, engineers, and consultants to support system configuration based on oven model, fuel type, routing requirements, and site conditions.

Marra Forni ventilation systems utilize factory-built, double-wall insulated chimney components paired with dedicated exhaust equipment, configured specifically for each project.

All systems are designed to be installed in accordance with manufacturer guidelines, applicable listings, and local code requirements.

For applicable gas and electric models, optional fan interlock controls may be available to automatically activate the exhaust system during operation.

Pizza Oven Exhaust Fan

Marra Forni EXFAN Series exhaust fans are engineered for use with direct-connected ventilation systems and commercial cooking ovens.

Available in multiple configurations, each system is selected based on duct length, routing, and airflow requirements to ensure reliable mechanical draft performance.

Paired with DWKL Series chimney systems, EXFAN equipment is designed for installation in accordance with manufacturer guidelines, project specifications, and local code requirements.

Optimal Ventilation Performance

Proper exhaust airflow is critical to the performance of commercial refractory ovens. Systems that are undersized or oversized can impact heat retention, efficiency, and cooking consistency.
Marra Forni ventilation systems are configured based on oven model, duct routing, and project conditions to support proper mechanical draft performance for each application.

Easy Cleaning & Maintenance

DWKL Series chimney systems are factory-built and insulated, with accessible cleanout and maintenance components designed to support routine inspection and service.
System fittings and offsets are manufactured for consistent assembly and installation in accordance with manufacturer guidelines.
Inspection and cleaning frequency should be determined based on usage, cooking application, and local code requirements.

Fire Protection Considerations

Fire protection requirements are determined by applicable codes and the authority having jurisdiction.
 
Marra Forni ovens are not evaluated or listed for the discharge of fire suppression agents into the oven. Fire protection system design and nozzle placement should be coordinated with a licensed fire protection contractor and local authorities.

Mechanical Exhaust Equipment

EXFAN Series exhaust equipment supports mechanical draft operation for applicable Marra Forni direct-connected ventilation systems.
 
Fan selection is based on project-specific factors, including duct length, routing, fittings, airflow requirements, and discharge conditions.
