WARNING
Installation requirements:
Installation must conform to the requirements of local and national directives and regulations for the installation of
gas-fi red equipment.
The humidifi er must be installed by a qualifi ed technician and meet the requirements of all governing codes.
Failure to follow these instructions could cause severe bodily injury or death.
• Provide a level, solid foundation for the humidifi er.
• Locate the humidifi er as near as possible to a chimney or outside wall so that the fl ue pipe from the humidifi er is
short and direct.
• Install the humidifi er where its electrical components are protected from water during operation and service.
• Install the humidifi er in a location away (and protected) from drafts. If installed in a separate room, follow the
instructions concerning combustion and ventilation air.
• Install the humidifi er in an area where leakage from the tank or its connections will not result in damage to the
adjacent structure or to lower fl oors of the structure. When such locations cannot be avoided, install a suitable drain
pan (adequately drained) under the humidifi er. The pan must not restrict combustion airfl ow.
• If located in an insulated space, keep the humidifi er free and clear of insulating materials. Insulating material can be
combustible. Inspect the humidifi er area when the humidifi er is installed or when insulation is added.
