Century FW3300 Installation and Operation Manual
38
Use 45 degree elbows where possible, instead of 90 degree elbows.
The rules below are based on those found in the CSA B365 installation code. Please
carefully follow these installation instruction rules, or those enforced where you live.
•
Maximum overall length of straight pipe: 3 m (10 ft.) including elbows.
•
Minimum clearance from combustible material: 450 mm (18 in.). The minimum
clearance may be reduced by 50 percent to 225 mm (9 in.) if suitable shielding is
installed either on the pipe or on the combustible surface.
•
The assembly should be as short and direct as possible between the stove and
chimney. The use of two 45 degree elbows is often preferable to a single 90 degree
elbow because less turbulence is created in the exhaust flow and they result in less
horizontal run.
•
Maximum number of 90-degree elbows: 2.
•
Maximum unsupported horizontal length: 1 m (3 feet).
•
Galvanized flue pipes must not be used because the coatings vaporize at high
temperatures and release dangerous gases. Use black painted flue pipes.
•
Flue pipes must be at least 24 gauge in thickness.
