SIZE AND SPACE REQUIREMENTS
3.1 The Wessex ModuMax Series boiler range has been designed to utilise minimum floor space by stacking boiler
modules, therefore it is important the plantroom has sufficient ceiling height to allow for installation and connection to the
flue system.
Also important is allowance for sufficient access at sides and rear of boiler for flue and pipework connections. See Figure
3.1.1 below.
