Ventilation
Each Wood Stone installation is unique and different. Because our ovens can be installed indoors or out, recommendations for ventilation vary. All indoor installations require an exhaust fan but some outdoor installations may not. Please consult your contractor or call the factory if you have any questions. (800) 578-6836
Indoor installations always require an exhaust fan at the end of your duct run.
Outdoor installation (free standing: no roof or enclosure) – in most cases, these installations don’t require an exhaust fan, just a chimney cap to protect your oven from the elements. If the need arises (wind or downdrafts), it’s easy to install an exhaust fan at a later date.
Outdoor installation (not free standing: enclosed, roof, patio/gazebo) We recommend you install an exhaust fan or at least wire for one in case you have need for it in the future (wind or downdrafts).
Duct Requirements
The oven must be vented using grease-rated duct. This is the type of duct material used in commercial restaurant applications. GREASE DUCT IS DIFFERENT FROM DUCT TYPICALLY USED FOR WOOD STOVES, FIRE PLACES OR RESIDENTIAL GAS EQUIPMENT. While grease duct can be fabricated and installed in accordance with NFPA 96, it is far more common in residential applications to use a manufactured, modular duct system listed as a grease duct. This type of duct is much easier to install, and depending on the brand/style will allow for tighter clearances to combustible construction than a fabricated duct. The duct most commonly used is Selkirk Metalbestos IPS. There are other options as well, such as Metalfab GS. Your venting contractor will need to source this through the appropriate local distributor in your area. Please contact Wood Stone if you have any questions about the type of duct that is required for our ovens. Grease duct is required for both indoor and outdoor installations.
Oven Taking Some Time to get to Temperature?
Things to consider before being concerned:
- Most ovens take 3-4 hours to get to temperatures between 500-600 degrees when heated from cold
- Is the flame on its highest setting?
- Do you have a exhaust fan for your oven? What setting is it on?
- If the flame is pulling hard in the oven and making a loud “wind” sound, the fan may be on too high of a setting. You need to lower the fan speed to the lowest setting that still prevents heat from rolling out of the oven opening (doorway).
- (For Bistro ovens with heat-shield doors): Open the doors by 2 inches, does the flame soften and become quieter?
