Flue pipe installation 

We have used our most popular Deltavent twin-wall flue systems to give a simplified step-by-step guide to flue pipe installation.

Before installation

• It is essential that the components are installed with the male spigot down against the flow of gases for all vertical applications. This will allow condensates, if any, to remain within the flue

Flue pipe installation

• Step 1 – Remove any dirt, grease and other contaminants from components where the sealant will be applied
• Step 2 – Apply an adequate amount of sealant to the male flange connection. Using the locating spigot of the male as a guide, simply push/slot the two parts of the Deltavent twin-wall flue system together (so the male spigot runs down)
• Step 3 – Fit the v-band. This has been designed as a two-piece item for easy assembly and must also be free from any contaminants (e.g. grease or oil)
• Step 4 – Apply sealant into the groove of the v-band before fitting
• Step 5 – Position both v-band parts around the Deltavent with the 10mm connection flange located within the groove
• Step 6 – Tightly fasten both joints using the stainless steel nuts and bolts

Important notes

• Nothing should pierce either the internal liner or the outer case at any point of the installation
• If Deltavent is exposed to external elements (e.g. rain or snow), it is essential to apply a bead of sealant into the grooves underneath the band
