Gasket
Customer best practice will still be needed:
• Use wet wrap when installing.
• Braze the joints.
• Let them cool down.
• Clean the brazing /welding area after the installation (remove remaining flux with a brush).
• This is an important operation and needs to be
done with great care to remove all remaining flux.
• Paint / Anti-corrosive needs to cover all open
steel parts, areas where the black original paint
has been burnt due to brazing and at least 3 cm
approx of the copper.
• Paint the joints twice.
