Boiler usage and advantages
Cast-iron sectional gas boiler VIADRUS G 90 is equipped with law-emission atmospheric burner and is
intended for burning pf low-pressure natural gas. The boiler is made in B
11BS
design it means it is equipped
with combustion gases reflux fuse.
It is suitable first of all for heating the middle–sized and bigger premises.
The use of gas valves with an automatic control and watch of the gas cap tightness at the burner makes it
possible to install the boilers in the boiler rooms of categories I and II. The boiler is only made as the hot-
water boiler with a forced circulation and work overpressure up to 400 kPa (4 bar). Before the dispatch the
boiler is tested for tightness by 800 kPa (8 bar) testing overpressure.
Boiler advantages:
1. High service life of the cast-iron boiler drum.
2. Simple operation and maintenance.
3. Reliable security and control elements
4. Gas combustion efficiency 92 %.
5. As a standard equipped with combustion gases reflux fuse.
6. Silent running and law electricity consumption.
7. Gas connected either from the left-hand side or from the right-hand side.
8. Connection of the output and return water either from the left-hand side or from the right-hand side (it
doesn’t apply to the 8-sectional version).
9. Possibility to connect the boiler in an cascade.
10. Possibility to equip with an equitherm regulation.
11. Two-stage burner (nominal/ reduced output).
12. Possible delivery in a decomposed state.
The content of harmful substances in the combustion gases is significantly lower than the values prescribed
by the guideline MŽP 05 – 98 „Environmentally friendly product “ and meets the requirements of the most
strict European standards.
