technical conditions that should be met by buildings and their setting, of 12 April

BEFORE THE BOILER IS STARTED, THE STACK MUST BE WARMED UP!
(see Chapter Boiler firing and operation)
The boiler does not require stack inserts; however, when operated all year
round – heating of a domestic hot water tank – this solution is recommended.
When low boiler temperatures are maintained for a long time, use of such
insert is obligatory. Maintaining low boiler temperature results in emission of wet
flue gases. This may result in moisture accumulation and corrosion of masonry
chimney stacks.
CHIMNEY STACK OPERATIONAL CONDITION SHOULD BE CONFIRMED
BY A LICENSED CHIMNEY SWEEP.
NOTE:
It is recommended to secure the chimney against consequences of flue gas-
es condensing (corrosion of masonry chimney stacks) by installing in the
stack a jacket of heat-resistant stainless steel.
7.5. BOILER CONNECTION TO A HEATING SYSTEM
The boiler should be connected to the heating system with screw connections;
it is forbidden to install the boiler by welding it to the system.
The main supply/return water system connections cannot be reduced below
a diameter of a connector installed on the boiler. Before starting works to connect
the boiler to the heating system check if all boiler sub-assemblies are in a good
operational condition and the boiler equipment is complete.
The SAS AGRO-ECO 17-100 kW boiler can be connected to an open vent-
ed or a sealed system, according to the requirements of current specific reg-
ulations of a country of destination and manufacturer guidelines specified
below. Boilers above 100 kW can only be installed in an open vented system.
A boiler can only be operated in a sealed system when the system is
equipped with reliable devices to remove excess heat according to the re-
quirements of current specific regulations of a country of destination.
NOTE:
It is recommended to connect the boiler to a heating system equipped
with a three- or four-way valve. Such connection protects the boiler against
low-temperature corrosion, preventing its premature wear.
