Overview

EN 1596:1998/A1:2004 is a European standard published by CEN that specifies requirements for dedicated liquefied petroleum gas (LPG) appliances, focusing on mobile and portable non-domestic forced convection direct fired air heaters. This amendment, approved in 2003, introduces technical revisions to the original 1998 standard to improve clarity, safety, and interoperability across member states. It supports compliance with EU directives and must be implemented by national standards bodies throughout Europe.

The standard governs design, safety features, installation, performance, and marking requirements essential for these LPG appliances used in commercial and industrial settings, excluding domestic applications.

Key Topics

• Scope and Modifications
  The amendment revises crucial operational parameters such as gas pressure limits (reducing from 4 bar to 2 bar), flame ignition rates, and extinction delay times to ensure safer operation.

• Gas Inlet Connections
  Specifications for gas inlet connections ensure compatibility and safety, with requirements for threaded connections and sealing washers.

• Air Flow and Ventilation
  Forced air draft burners must include devices that verify adequate air flow during ignition and operation, supporting safe combustion and preventing hazardous conditions.

• Temperature Limits
  Air delivery temperatures are controlled, with adjustments made from 80K to 70K difference limits, and no temperature limit for commercial drying applications.

• Markings and Warnings
  Appliances must carry clear data plates with serial numbers, gas types, supply pressures or pressure ranges, and explicit warnings that the heaters are not suitable for heating domestic habitable areas. This ensures users are aware of intended non-domestic use only.

• Installation and Use Instructions
  Instructions must detail safety warnings, gas pressures, and operational procedures tailored for public and commercial buildings, reinforcing compliance with national ventilation and safety regulations.

• Packaging Requirements
  Packaging must include warnings to prevent misuse in domestic premises and ensure safe transportation and handling.

---

Applications

EN 1596:1998/A1:2004 applies specifically to mobile and portable LPG air heaters used in:

• Construction Sites
  Temporary heating during building or renovation.

• Warehouses and Workshops
  Providing controlled, forced convection heat for employee comfort or material processing.

• Event Spaces and Public Buildings
  Non-domestic use where temporary or supplemental heating is needed under regulated conditions.

• Commercial Drying Processes
  Situations where heated air aids drying operations without temperature restrictions.

This standard ensures these heaters operate safely, meet EU and national regulations, and include essential safety features like flame supervision and air proving devices.

Related Standards

• EN ISO 228-1
  Specifies requirements for pipe threads where sealing is not made on the threads - relevant for gas inlet connections.

• CEN/TC 181 Standards
  The technical committee responsible for dedicated LPG appliances, providing related specifications for other LPG device categories.

• National Ventilation Regulations
  Installation according to EN 1596 must also comply with specific national rules for air supply and ventilation to maintain safe indoor air quality.
