FTHW Wall-Mounted Gas Condensing Heating Only Boiler

FOR YOUR SAFETY : This product must be installed and serviced by a professional service technician, qualified in hot water boiler and heater installation and maintenance. Improper installation and/or operation could create carbon monoxide gas in flue gases which could cause serious injury, property damage, or death. Improper installation and/or operation will void the warranty.

WARNING
If the information in this manual is not followed exactly, a fire or explosion may result causing property damage, personal injury or loss of life.
Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any phone in your building.
• Immediately call your gas supplier from a nearby phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.

Familiarizing yourself to THE FT

Heating Only Boiler

The FT is a highly efficient, wall mounted, condensing and fully modulating, residential boiler. This Users Manual will guide you into the basics of operating your FT
Please reference the Installation and Operation Manual for complete details. Doc # 1342

The FT, Heating Only, Boiler

Shown is the FT Heating Only 140 MBH.
All sizes are very similar in component layout.

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.

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.

Shutting Down the FT

1. Turn off the main electrical disconnect switch.
2. Close all manual gas valves.
3. If freezing is anticipated, drain the FT and be sure to also protect building piping from freezing. All water must be removed from heat exchanger and condensate trap or else damage from freezing may occur. Please refer to the Install and Operating Manual.
   This step to be performed by a qualified service person.
