- Only a Gas Safe registered engineer should perform the removal of the old gas section and the installation of the 0020110996 unit.
- After installation, the engineer must perform a formal tightness test and combustion analysis to verify the boiler is operating within safe parameters.
- No user-serviceable parts exist inside the gas section; do not attempt to dismantle or lubricate the valve mechanism.
