5 Preparation of boiler and place of installation
Before installing the hopper, make sure the pellet boiler is installed according to the instructions in the manual and
in compliance with the current regulations.
Make sure the electrical system and sockets are suitable for the maximum absorption
of the boiler and hopper.
The boiler must also be suitably separated from flammable or combustible materials by means of air spaces or the
use of appropriate protective insulation; floors and/or ceiling-coverings in flammable or heat sensitive material must
be protected by panels of insulating material.
Make sure that in the place of installation there are spaces at the sides and rear of the boiler, necessary for
servicing and cleaning the unit, fume ducts and the flue. Also make sure the boiler pellet hopper and supplementary
hopper are easily accessible for loading and checking the fuel level.
The minimum distances for maintenance and safety must comply with the following table:
Before securing the supplementary hopper, operate on the boiler from the side for installation, proceeding as
follows:
- remove the knockouts for the auger tube and electrical cables;
- remove the relevant cap from the hopper;
- fix the flanged spacer tube with screws from the outside of the boiler inwards;
- check for the level sensor in the boiler pellet hopper.
