Ecodense Control Instructions Before Start-Up - Ecodense ROOF TOP Series Installation, Operating And Maintenance Manual

11. ECODENSE CONTROL INSTRUCTIONS BEFORE START-UP

1. Ensure that boilers are mounted on fixed, firm and robust wall. Use metal hangers on improper
walls.
2. Ensure that every boiler has connected to their own 6A fuse.
3. Maximum operation pressure is 6 bars in the closed circuit. Ensure that in CASCADE
SYSTEMS, Balance tank is used below 6 bars and plate heat exchanger is used above 3 bars. In
situation where plate heat exchanger is used, Expansion tanks with proper capacities must be used
at both outgoing and return lines.
4. In single or CASCADE applications, safety valve fixed to 6 bars must be used. Adjustable safety
valve must not be used. As a minimum requirement of the system, use the safety valve as shown
in the package/hydraulic schematic.
5. Control the sufficiency of capacity of circulation pump used in primer circuit (between boiler and
balance tank).
6. In single and cascade type condensing boiler systems, flue pipe connections should be assembled
in a compatible direction and angle and also in a sealed manner according to the boiler condensate
outputs. Chimney connections must be made in the form of air suction or hermetic chimney
connection directly from the environment in accordance with the standard rules.
7. Ensure that there are components such as automatic air vent, air separator and dirt/sediment
retainer on the system and that it is used in sufficient volume and quantity according to the scheme
for the relevant installation model.
8. A manometer to monitor system pressure must be present in system, control if it is mounted on the
system.
9. Control if the condensing fluid siphon is made of plastic, isolated against frost, at correct radius
and connected to condensing fluid drain with an angle. It should not be connected to rain drain.
10. Ensure that circuit and system are tested against leakage and system pressure is sufficient.
11. Ensure that gas pressure complies with boiler operation instructions. In situations where gas
pressure is higher than required pressure, a regulator must be used.
12. Ensure that sensors on boiler feed and circuit (outgoing-return temperature, ambient temperature,
boiler temperature sensors) are wired correctly. Wires of boiler feed and other equipment on
circuit belong to user.
13. Shut-off valve must be installed as safety device on the line where gas pressure is reduced from
300 mbar to 21 mbar pressure by regulator.
14. In boiler installations with 6 or more capacity of 150 kW and higher, the gas line must be divided
into 2 or more sections depending on consumption and should be installed with the regulator.
