The Scope Of Modernization Also Includes Sealing The Chimney Duct With An Acid-Resistant Steel Pipe, Only If Necessary In A Protocol. The Ordering Party Does Not Have An Inventory Of The Existing Chimney To Which The Existing Heating Boiler Is Connected, Therefore, If During The Renovation Of The Boiler Room, After Dismantling The Old Boiler, As A Result Of An Inspection Carried Out By A Chimney Sweeper Or Construction Manager, It Is Found That The Existing Chimney Flue Does Not Have The Appropriate Cross-Section For The Boiler Used Required By The Manufacturer And Applicable Regulations, The Contractor Should Drill The Chimney Flue To The Appropriate Diameter Recommended By The Boiler Manufacturer. Also, If It Is Found (In The Form Of A Report Signed By A Chimney Sweeper Or Construction Manager And Approved By The Supervisory Inspector) That The Existing Chimney Flue Is Burnt Or Leaking, It Is Essential To Seal The Chimney Flue With An Acid-Resistant Steel Pipe. The Height Of The Existing Room In Which The New Gasification Boiler Is To Be Installed Is 2.20 M. Due To The Lack Of Air Supply In The Boiler Room, Air Supply To The Boiler Room Should Be Made With A Cross-Section Of At Least 250 Cm2. The Contractors Responsibilities Will Also Include Performing All Tightness Tests Of The Existing Or Modernized Internal Installations, And, If Necessary, Also Implementing The Necessary Electrical Installation With A Socket Supplying The Gasifying Boiler To Be Installed, Preparing Appropriate Acceptance Reports For The Installed Devices, And A Chimney Sweep Report Allowing The Boiler Room To Be Installed. And Chimney Flues For Use. Moreover, In The Scope Of Modernization Of The Boiler Room, The Contractor Will Be Responsible For Dismantling The Existing Internal Entrance Doors From The Utility Room To The Boiler Room, And Reinstalling (Right) New, Non-Standard Technical Doors With Dimensions 0.85X1.90 M Covered With Galvanized Sheet Metal On Both Sides, As Well As Installation Of A New Door Leaf Of The Technical Door (Right) To The Staircase, Also Covered With Galvanized Sheet Metal On Both Sides. 3. Installation Of A Wood Gasification Boiler - The Scope Of Work Includes The Dismantling Of An Old Boiler (Unnamed Boiler) With A Capacity Of Approximately 15 Kw For Altech Solid Fuel, And The Installation Of A New Steel Or Cast Iron Wood Gasification Boiler With Min. Power Of 20 Kw And Energy Class A+, Operating At A Temperature Of 80-90 Degrees, Equipped With A Weather-Controlled Central Heating Circuit. The Boiler Should Have An Exhaust Fan (Depending On The Model) And Automation That Controls The Combustion Process. A Solid Wood Gasification Boiler With A Humidity Of Up To 20% Should Be Used, Along With Protection Devices And A Control Panel Equipped With Circulation Pumps For The Boiler And Central Heating Installation. And Loading The Domestic Hot Water Capacity Heater, The Expansion Vessel Of The Open System, And The Accumulation Tank, Possibly Equipped With A Flow Coil For Heating Domestic Hot Water. Temperature Valve And 3-Way Mixing Valve. The Boiler Should Be Made In Class 5 Of Energy Efficiency And Emission According To The Pn-En 303-5 Standard, And In Accordance With The Eu Regulation Regarding The Ecodesign Certificate. Additionally, The Boiler Must Meet The Requirements Of Energy Efficiency Class A+ With The Ecodesign Certificate. The Thermal Technology Of The Boiler Room Should Consist Of The Following Circuits: - Boiler Circuit With A Mixing Pump And Temperature Valve, - Accumulation Tank (Buffer) With A Capacity Of 1,000 Dm3 (The Buffer Capacity Should Be Simultaneously Adapted To The Requirements Of A Specific Boiler To Ensure Operational Compatibility), Acting As A Hydraulic Coupling And Allowing Effective Operation Of The Boiler, - Heating Circuit With A Three-Way Mixing Valve (Weather-Controlled) For The Building, - Circuit Loading The Domestic Hot Water Tank. The Boiler Circuit Should Include The Following Devices: - Water Boiler - Mixing Pump - Return Protection Temperature Valve Min. 55 Degrees C. - Security Expansion Vessel With A Capacity Of Min. 50 L. The Mixer Circuit Should Include The Following Devices: - Mixer Circuit Pump, - Three-Way Valve With An Actuator, - Weather-Controlled Three-Way Valve Regulator, - Sludge Filter. The Boiler Operating Parameters Should Enable Achieving An Operating Temperature At The Boiler Outlet Of Not Less Than 80Oc And Not Exceeding 90O C, With An Operating Pressure Not Higher Than 2 Bar, And Adjust The Settings To The Thermal Powers Indicated Above (The Maximum Boiler Power Indicated By The Manufacturer May Be Higher When Adjusting The Settings To The Parameters Resulting From The Attached Energy Audit). 4. Modernization Of The Domestic Hot Water Installation – Necessary Hot Water Installation (Only Within The Boiler) Should Be Made Using Alupex/Pp Technology, Clamping Steel, Covered With Thermal Insulation Compliant With Pn Standard, Without The Need For Any Grooves In Walls And Ceilings. Connect The Wood Gasification Boiler To The Existing Domestic Hot Water Installation In The Boiler Room Without Making Additional Drilling Holes Through The Ceilings And Internal Walls (Additional Drilling Holes Through The Ceilings And Walls Should Only Be Made If There Is A Justified Need To Do So In Consultation With The Supervision Inspector). The Scope Of Modernization Works Also Includes The Removal Of Unnecessary Elements Of The Old Installation (Without Chiseling Out, Only By Plugging Them With The Wall Face And Filling The Gaps With Plaster) In Places Where The Installation Was Liquidated, Without Painting The Walls. 5.
