The following technical instructions and notes are intended for installers so they may make a perfect
installation.
The instructions for igniting and using the boiler are given in the boiler manual.
1. PACKING AND TRANSPORT
The unit is sold on a wooden pallet protected by packing made of strengthened cardboard.
The packed unit must only be transported and lifted by holding it underneath the pallet.
