ALFA OVENS VENTING GUIDE FOR WOOD FIRED OVENS
Basic Guideline for ALFA Ovens Flue and Obstruction Clearances:
- Single Wall Flue Piping: Allow 18” of clearance around pipe
- Double Wall Flue Chimney: Allow 3” of clearance around chimney
- Combustible Clearance: Minimum of 3 feet below the ceiling is required
- Chimneys must extend at least 3 feet above the highest point where it passes
through a roof, and at least 2 feet higher than any portion of a building within
10 feet
- Never ll any required clearance with any insulation or other materials
OFFSET ELBOW INSTALLATION:
- Avoid elbows if at all possible, as a vertical pipe or chimney is the most efcient
- Pipe or chimney systems may have a maximum of 2 offsets (two elbows total)
of 30-degrees from vertical
- Elbows are manufactured in 15-degree and 30-degree angles, measured from
the vertical
- Do not combine elbows to create steeper angles and never exceed 2 elbows in
one pipe or chimney system
- A single elbow is dened as a 30-degree bend and then a 30-degree correction
(one set)
- ForExample:Youcouldhavea30-degreebendwitha0-48” horizontal pipe or
chimney and then another 30-degree bend back to the vertical position
- Do not use with forced-draft, positive-pressure appliances.

WARNING: DO NOT USE (2) 30-DEGREE ELBOWS
TO CREATE A 60-DEGREE ANGLE!
THIS VOIDS ALL WARRANTIES AND PRESENTS A FIRE HAZZARD
WITHIN THE PIPE OR CHIMNEY SYSTEM.
If your installation requirement cannot meet the basic standards be sure to
consult a professional and obtain necessary permits in advance.
