General Information
1A. Introduction
This manual contains installation, operation and
maintenance instruction for the Mighty Max hydronic
boiler, Model HH, sizes 320M, 400M, 520M, 625M,
775M and 1000M. Review all application and
installation procedures completely before proceeding
with the installation. Consult the local factory

lists the input/output ratings for each boiler size.
The indoor version is convertible for outdoor use
with the installation of a conversion kit. See Section 6,
Parts List, for part number.
