Eco Max 613/2e, does it have a built in auto by-pass

I am installing a pressurised hot water system. My gas boiler is an Eco Max 613/2E, is it fitted with a built in auto by-pass? Or will I need to fit an external one. The seriel no of the boiler 2105333051620001006075N (last D or O)

Thank you for Your help

Hi Daniel,

Indeed the EcoMax 600 series is fitted with an automatic bypass valve.  You can see it in our exploded parts list, please see link below:
