Maga MA 15, Руководство по эксплуатации и обслуживанию

Страница: 3 / 27

1. Purpose of Use
The MA hot-water boiler is intended for heating homes and other types of buildings. The boiler is designed exclusively to
work on burning wood. Any dry wood such as chopped logs or wood chips with maximum length of 500 mm (MA 15 – 350
mm, MA 80 – 650 mm) can be used as fuel for this boiler. Recommended log diameter is 150 mm. Logs with larger diameters
can be used as well (max. 200 mm). If so done, the boiler’s rated output capacity will decrease and the period of burning will be
extended Minimal diameter of wood chops is 60mm. In case these parameters are not met, extreme overheating of boiler may
occur in the burn-out chamber and ceramic parts will be damaged consequently due to enormous heat.
A large wood storage bin will help replace and eliminate the most laborious operations associated with the preparation of
wood fuel – i.e. the sawing and cutting of logs into pieces of an appropriate size. This practice will save not only physical
exertion, but also time necessary for the work.
