IN THE GARDEN
When installing the ALFA Oven in your outdoor cooking area with the venting away from any structures or low ceilings, the ALFA supplied high-quality stainless steel pipe and cap are sufficient.
ON THE TERRACE OR UNDER A PERGOLA
For indoor ALFA oven venting installations, or outdoor settings where your wood-fired oven will be under a roof structure, pergolas, or terrace.
If you are penetrating through an object overhead, you must remove the single-walled pipe provided and start with the pipes and chimneys manufactured by specialized companies.
If a bend is needed to change the pipe or chimney direction to avoid an obstruction, you can use up to (2) 30-degree or less angles but NEVER together to form a 60-degree bend.
