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 bottom and top 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 qualied 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
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 lling must only
be done by a qualied service person.
2.4 Full Service Every Year
In addition to the annual visual inspections, a
qualied 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 qualied 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 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 qualied service person.
