Concentric Vent Support; Flue Options - Baxi DUO-TEC COMPACT 30 GA Notice D'installation Pour L'installateur

Concentric Vent Support

9.37 in
238.00 mm
15.75 in
400.00 mm
All venting must be supported every 39" (1 m) with a fixed clamp.
A: steel strapping or equivalent
Note:
Ensure that the vent is sloped towards the boiler approximately 0.79 in for every 3.28 ft (2.00 cm for every 1.00 m).
For horizontal flues a minor deviation from the horizontal is allowable, provided it results in a downward slope towards the boiler.
For the vertical flue terminal assembly refer to the separate installation instructions supplied with the assembly.
Additional flue components are available as follows:
1.64 ft / 0.50 m
45° bend
3.28 ft / 1.00 m
90° bend
• Locate the flue elbow on the adaptor at the top of the boiler. Set the elbow to the required orientation (rear, right or left).
• Measure the distance from the outside wall face to the elbow. This dimension will be known as 'X'.
• To dimension 'X' add "Y" + 2 in (50 mm). This is the total dimension of the vents.
• Taking the air vent, mark the above dimension Measure the length of waste material, and transfer the dimension to the flue.
• Remove the waste from both vents (flue and air vents). Ensure that the cut ends are square and free from burrs.
• Insert the flue into the intake air vent and pass them through the hole in the wall
WARNING
• Check all measurements before cutting. Clearance to combustible materials when using a concentric vent system
is zero.
• After installing vents make sure that there is no recirculation of combustion by using a regularly calibrated analyzer.
• Ensure a minimum downward slope of 0.79 in / 2.00 mm for every 3.28 ft / 1.00 m of the flue length toward the boiler
at least 2º.
• Ensure that the terminal is positioned with the slots to the bottom.

Flue Options

• The boiler can be fitted with flue systems as illustrated.
• Any additional "in line" bends in the flue system must be taken into consideration.
1.64 ft / 0.50 m
45° bend
3.28 ft / 1.00 m
90° bend
The elbow supplied with the standard flue is not included in any equivalent length calculations
• The illustrations below show examples of maximum equivalent lengths.
• Instructions for guidance and fittings are included in each kit.
