• Compressive strength of flue and air supply ducts
• Tensile strength
• Lateral strength
• Wind load
• Gas tightness of flue duct
• Gas tightness of air supply duct
• Terminal performance
• Terminal resistance
• Rainwater ingress
• Flow resistance
• Water vapour diffusion resistance
• Dimensions and tolerances
