SIST EN 226:2000

Overview

EN 226:1987 - "Atomizing oil burners - Connecting dimensions between burners and heat generators" (adopted as SIST EN 226:2000) is a CEN standard that defines the mechanical and interface requirements for the connection between atomizing oil burners and heat generators (boilers, furnaces). The standard also addresses the standardization of automatic control devices and flame detectors used with atomizing oil burners to promote interchangeability, safe operation and simplified installation.

Key Topics

• Connecting dimensions and interfaces: Specifies the essential dimensional relationships for mounting burners to heat generators so different manufacturers’ units can be exchanged without major modifications.
• Mounting geometry: Covers flange positions, centre-lines, and envelope clearances to ensure correct alignment and service access.
• Control and detector interfaces: Defines standardized provisions for connecting automatic controls and flame detectors, facilitating compatibility of safety and control equipment.
• Documentation and marking: Requires clear identification and technical data on burner nameplates and documentation to support installation, maintenance and regulatory compliance.
• Scope for liquid and solid fuel burners: Classified under liquid and solid fuel burners (ICS 27.060.10), the standard focuses specifically on atomizing oil burner connections while aligning with broader burner safety principles.

(Note: EN 226:1987 establishes interface and dimensional requirements; it does not specify combustion settings or detailed electrical control circuits.)

Applications

• Manufacturers of atomizing oil burners and heat generators use EN 226 to design compatible mounting flanges and control interfaces, enabling market interoperability.
• Boiler and furnace OEMs adopt the standard to simplify supplier integration and reduce custom adaptor requirements.
• HVAC designers, installers and service technicians rely on the standard to ensure safe, efficient retrofits and replacements of burners.
• Testing labs and certification bodies reference the standard when verifying mechanical conformity and component compatibility.
• Procurement and maintenance teams use the standard to specify replacement burners or controls that will fit existing equipment.

Related Standards

• EN 226 is part of the broader set of EN standards covering burners, boiler safety, and control equipment. It has been adopted nationally (e.g., SIST EN 226:2000 in Slovenia). For complete compliance, users should consult complementary EN standards for burner controls, combustion safety, emissions and boiler performance.
