4.11.6. Connection to a C53 air vent
Type C53 connection:
Air inlet and gas extraction via 2 separate ducts.
IMPORTANT:
Connecting a VARMAX boiler in a C53 configuration requires the use of
accessory kits.
The table below gives the reference of the available kits depending on the
boiler model and the maximum straight lengths authorised for the air and
flue-gas ducts.

The lengths given include the lengths of the flue-gas terminal but do not
include the air terminal (measure taken on the outside of the wall).
In addition, in the duct length calculation, the following equivalences must
be used;
For ducts with diameters 150 mm and 160 mm:
- 90° elbow = 1.5 m of straight duct
- 45° elbow = 0.8 m of straight duct
For ducts with diameters 180 mm and 200 mm:
- 90° elbow = 2 m of straight duct
- 45° elbow = 1.1 m of straight duct
In addition, in the duct length calculation, the following equivalences must
be used;
- 90° elbow = 1.5 m of straight duct
- 45° elbow = 0.8 m of straight duct
The terminal's installation must comply with the rules in §
4.11.
To facilitate mounting of flue-gas ducts (PPTL), coat the joints with liquid
soap or a suitable grease (provided in the "terminal kit").
IMPORTANT:
The weight of the ducts (air and flue-gas) must not be supported by
the boiler's connecting parts.
