Gas combi boiler

Product catalog summary
Overview: The document outlines the specifications and features of ComfortLine's gas-fired condensing boilers, emphasizing energy efficiency and compliance with environmental standards. It details various models, including wall-mounted boilers and condensing centers, and provides technical specifications, benefits, and installation requirements.
Specifications:
  • Wall Mounted Boilers (CGB/CGB-K): These models have a modulation range for flow/return temperatures of 50/30°C, with outputs from 3.6 to 24.8 kW. They feature a sealed combustion chamber, high efficiency up to 110% (Hi), and a pivoting heat exchanger for easy maintenance.
  • Condensing Centers (CGS/CGW): These combine a boiler with a stainless steel DHW heat exchanger and stratification cylinder, offering high DHW performance and energy efficiency through innovative insulation and a 'DHW turbo' system.
  • High Capacity Boilers (CGB-35, -50, -75, -100): Suitable for larger installations, these models provide outputs up to 98.8 kW, featuring robust heat exchangers and easy maintenance and installation.
Key Features:
  • All models are DVGW certified and comply with German and European clean combustion directives.
  • Equipped with premix burners for natural gas and LPG, ensuring high efficiency and low emissions.
  • Installation and maintenance are simplified with accessible components and external flue gas test ports.
  • Designed for open and balanced flue operation, with cascade operation options for larger systems.
Installation and Maintenance:
  • Boilers are designed for easy installation with modular components and optional accessories for quick setup.
  • Maintenance is facilitated by pivoting heat exchangers and accessible cleaning ports.
  • Models can be split into modules for easier handling and installation in confined spaces.
Environmental and Efficiency Standards:
  • Boilers meet 'Blue Angel' certificate requirements for environmental excellence with natural gas operation.
  • High standard efficiencies are achieved, with up to 110% (Hi) and 99% (Hs) for optimal energy utilization.
Flue Systems Overview: The document provides technical specifications and installation guidelines for balanced flue systems in wall-mounted gas-fired condensing boilers, detailing configurations and necessary components.
Flue Specifications: It details flue connections, including DN 80 and DN 100 sizes, and their applications in balanced and open flue systems, specifying maximum lengths based on boiler models from 35 kW to 100 kW.
Installation Procedures: Emphasizes adherence to local building regulations and the use of original WOLF components for optimal performance, with instructions for adapting installations to regional requirements.
Standards and Certifications: References compliance with EN 13384 calculations and lists CE-certified flue pipes and components for safety and regulatory adherence.
Recommendations: Advises using original WOLF components for concentric routing of flues and consulting local heating engineers for installation queries.
Accessories: Lists control and hydraulic accessories, including programming modules, safety valves, and connection sets, with specific accessories for solar heating and DHW circulation.
Key Data: Includes tables with maximum flue lengths, fan draught specifications, and component part numbers, essential for planning and installation.
