MagnaTherm FT User's Manual
4. In the Event of Power Failure
The MagnaTherm will not operate during an electrical power outage. If there is an extended power outage
with danger of freezing, then the MagnaTherm (and all other water systems) should be completely drained.
Before draining the unit, turn off the gas and turn off the main power switch. When you replace the unit in
service, refer to the "Installation and Operation Manual" for instructions on filling and purging.
5. General Care
Keep the area around the MagnaTherm clear and free from combustible materials, gasoline and other
flammable vapors and liquids. Clean the jacket surfaces with a damp cloth and mild soap. Do not use
flammable cleaning materials. Keep the vent terminal free of obstructions. Do not pile snow against the vent
terminal.
6. Annual Inspection and Service
You should visually inspect the vent pipe once a year. Should any corrosion or leaks exist, have the affected
parts replaced.
Once each year a qualified service agency should conduct a detailed inspection of all flue product carrying
areas of the boiler and vent system. Follow the service instructions in the "Installation and Operating
Instructions Manual" for the MagnaTherm.
Once each year inspect the condensate drain line, vent line, condensate PVC fittings, the condensate
trap and condensate neutralizer (if installed). If necessary, disassemble and flush with fresh water and
reassemble.
Once each year inspect and clean the air inlet filter. See the Section 11 of your units Installation and
Operation Instructions for a complete list of maintenance items.
