Combustion gases
• All gas heaters must be connected in a leak-roof manner to
a gas evacuation pipe of adequate dimensions.
• The flue must:
– be vertical (reduced horizontal sections or no
horizontal sections at all)
– be thermally insulated
– have an exit above the maximum roof level
• A flexible or rigid pipe should be used, fit it inside the flue
socket. The external diameter of the pipe should be slightly
smaller than the dimension specified in the appliances
dimensions table.
• The extremity of the evacuation pipe must be protected

evacuation pipe is placed between the ledge
and the ring of the flue.
Where these conditions are not possible to achieve, an
alternative location must be selected.
