The FT is a floor standing, condensing and

fully modulating, residential boiler and

water heater.

This Users Manual will guide you into the basics

of operating your FT floorstanding boiler.

Please reference the Installation and Operation

Manual for complete details (Doc 1505).

2. Caring For Your FT

Your FT will require very little maintenance.

However, as with any ne appliance, there are certain

steps that should be taken to ensure continuing

optimum performance.

2.1 General Care

Keep the area around the FT clean and free from

combustible materials, gasoline and other ammable

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 openings on the boiler free for proper

ventilation of interior components.

Do not obstruct or block a free ow 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 ammable

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 qualied service person.

2.3 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

this combi boiler, turn off main electrical disconnect

switch. When placing back in service, refer to Section 3

of this Manual for instruction. All draining and lling must

only be done by a qualied service person.

2.4 Full Service Every Year

In addition to the annual visual inspections, a

qualied service agency should conduct a detailed

inspection of all ue product carrying areas of the boiler

and its venting system.

3. Shut Down and Restart

3.1 To Start the FT

If drained, please refer to the Install and Operating

Manual to ensure that the complete ‘Setup’

procedure has been followed before starting this

boiler. A complete ‘Setup’ must be performed by a

qualied service person.

3.2 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 the 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 qualied service person.
