Ventilation Hood In Sheet 2-Cube Concrete Black 125/160mm TJB

In the case of concrete/clay boilers, the boiler/boilers lying above are pushed up towards the ridge to facilitate installation of the upper fitting. Mount the upper fitting on the hood at the same slope as the roof. This is done by sticking the channel down through the lower fitting. The duct must be insulated with building-approved fire-rated insulation. Then screw the upper fitting to the base.

After the installation of the upper fitting for concrete/clay boilers, the boiler/boilers lying above are pushed back. Thread on top of the top fitting. Install in open in plumb, screw phase, it in the upper fitting with the supplied sheet metal screws.
