Please reference the Installation and Operation Manual for complete details. Doc# 1487

Caring For Your FT

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

2.1 General Care
Keep the area around the FT Series Combi clean and free from combustible materials, gasoline, and other flammable liquids and vapors.
The FT Series Combi must be completely isolated and protected from any source of corrosive chemical fumes such as trichloroethylene, perchloroethylene, 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.

2.2 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.

2.3 In the event of a Power Failure
The FT Series Combi can not be operated during an electrical power outage. If there is an extended power outage with the danger of freezing, then the FT Series Combi (and all other water systems) should be drained completely. When draining the boiler, turn off the 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.

2.4 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 FT Series Combi and its venting system.

DANGER

Scalding may occur within 5 seconds at a setting of 140°F (60°C). Water temperatures over 125°F can cause severe burns or death from scalding. Children, the disabled, and the elderly are at the highest risk of being scalded. Read all instructions before setting the temperature at the appliance. Feel water before bathing or showering.
The manufacturer strongly recommends the use of an anti-scald mixing valve at a domestic hot water outlet (boiler location) to reduce the potential for scalding.
Contact Manufacturer for recommended models. Check with local codes.
