6.3 Boiler connections
The diagram to the left shows the main plumbing
connections to the Bio-Tec boiler. Connection
sizes for the 35kW model are;
Flow
1 ½ ”
Return
1 ½ “
Filling /draining (on return conn.) ½ “
6.4 Flue Installation
A properly sized and insulated twin wall flue is critical
to the safe and efficient operation of the Bio-Tec
boiler. Table 1 shows the components of the flue
system provided by Firebird.
Key considerations with the installation of the Bio-Tec
flue are;
•
The flue must be insulated to avoid
condensation and tar build up
•
A minimum inner diameter of 200mm is required
for the 35kW Bio-Tec
•
Minimal distance between boiler and the vertical
section of flue should be 500mm
•
Flue must leave boiler with a 45 degree rise
•
Good access for cleaning must be provided
Determining the correct chimney size
Having the right draft and construction is critical to the
efficient and safe operation of the Bio-Tec boiler. An
insulated flue must be used with a minimum inner
diameter of 200 (8”).
Flue height must be according to the chart right.
