Overview

EN 722-1:2004 (CEN) - "Leisure accommodation vehicles - Liquid fuel heating systems - Part 1: Caravans and caravan holiday homes" specifies safety requirements for installing oil‑fired (liquid fuel) heating systems in caravans and caravan holiday homes. Approved by CEN in July 2004 and superseding EN 722-1:1996, the standard covers installation, components, and safety features to ensure safe operation of liquid fuel heating systems as defined by EN 13878.

Key Topics & Requirements

  • Scope and applicability
    • Applies to liquid fuel heating systems using oil fuels (see EN 13878 for definitions).
    • Note: ventilation requirements are covered separately in EN 721.
  • General installation
    • Install in accordance with equipment manufacturer’s instructions.
    • Systems must be leak‑free and use materials suitable for liquid fuels.
  • Oil tanks
    • Tanks must allow filling/draining from outside and, if separate, be in a ventilated fuel storage compartment with bottom drainage.
    • Capacity limits: maximum 50 L for caravans, 200 L for caravan holiday homes.
    • Stopcock required at each tank outlet and must be readily accessible.
    • Measures to prevent fuel spillage inside or beneath the vehicle when filling.
  • Heating appliances
    • For caravans: only room‑sealed appliances permitted.
    • For caravan holiday homes: appliances drawing combustion air from inside the vehicle are allowed.
    • Combustion products must be ducted to the outside; evacuation under the vehicle is prohibited.
    • Flue terminals: sited per manufacturer; minimum clearances - not within 500 mm of refuelling/breather outlets and not within 300 mm of habitation ventilators or opening windows. If a terminal is directly below an opening window, automatic shut‑off when the window is open is required.
    • Appliances must be accessible for inspection, service and replacement.
  • Fuel pipes and joints
    • Acceptable materials: seam‑welded or seamless steel, stainless steel, copper, or manufacturer‑recommended materials.
    • No soft‑soldered joints; use flat‑faced washered or compression joints; protect against corrosion and mechanical damage.
  • Flues
    • Non‑combustible, sealed flue pipes; remain secure during motion; weatherproofing and caps required.
    • Inspections must be possible via removable panels or mirrors/feel.
  • Fire valve
    • Thermally operated fire valve must be fitted to shut off fuel supply on overheating.
  • User's handbook
    • Manufacturer must provide operation and maintenance instructions in the language of first sale, including fuel specification and suitability for use while in motion.
