ASSEMBLY GUIDE FOR TRENCH CONVECTORS
-
Prepare a suitable place on the subfloor of the following dimensions:
• width of the convector duct + min. 80 mm,
• length of the convector duct + min. 40 mm,
• depth of the convector duct + 2 – 25 mm (as measured from the level of the finished floor). -
Screw levelling bolts into pre-drilled holes on the bottom of the duct and attach the floor fixing brackets to the outside of the duct (included in the installation kit).
-
Position your trench convector in the previously prepared place in the subfloor. Lay soundproofing insulation (e.g. mineral wool, foamed polystyrene, foam) between the convector duct and the subfloor.
-
Level and stabilise the convector duct.
-
Connect the flow and return pipe from the heating system according to the system design. For models with fans (F1S,…), connect all necessary electric wiring. Cover the water and electric connectors with the cover plate included in the installation kit.
-
Pressure test the convector to ensure there are no leaks.
-
Cover the convector duct with the protective chipboard until all construction work has been completed.
-
Fill the gaps between the convector duct and the floor slab with concrete or low expansion foam.
-
Once the project is finished remove the chipboard.
-
When the concrete and foam are completely cured, clean the inside of the duct and the convector itself.
-
Unroll the roll-up decorative grille over the convector.
