Caring For Your FT

Your FT will require very little maintenance.However, as with any fine appliance there are certain steps that should be taken to ensure continuing optimum performance.

• Your FT will require very little maintenance.
  However, as with any fine appliance there are certain steps that should be taken to ensure continuing optimum performance.

• General Care

  • Keep the area around the FT clean and free from combustible materials, gasoline and other flammable liquids and vapors.
  • The FT must be completely isolated and protected from any source of corrosive chemical fumes such as trichlorethylene, perchlorethylene, chlorine, etc.
  • Keep bottom and top openings on the boiler free for proper ventilation of interior components.
  • Do not obstruct or block a free flow of air to the boiler to ensure proper ventilation.
  • If desired, clean the jacket surfaces with a damp cloth and mild detergent. Do not use flammable cleaning materials.
  • If sidewall vented, keep the vent terminal clear of obstructions — do not allow snow to cover the vent terminal. Clean the intake screen often, and then develop an appropriate maintenance schedule.

• Annual Inspection of Flue and Vents
  Visually inspect the vent pipe once a year. Should any deterioration exist, have the affected parts replaced by a qualified service person.

• In the Event of a Power Failure
  The FT can not be operated during an electrical power outage. If there is an extended power outage with danger from freezing, then the FT (and all other water systems) should be drained completely. When draining the boiler, turn off main electrical disconnect switch. When placing back in service, refer to Section 3 of this Manual for instruction. All draining and filling must only be done by a qualified service person.

• Full Service Every Year
  In addition to the annual visual inspections, a qualified service agency should conduct a detailed inspection of all flue product carrying areas of the boiler and its venting system.
