Determine boiler location
Provide air openings to room:
FTXL alone in boiler room
1. No air ventilation openings into the boiler room are
needed when clearances around the FTXL are at least
equal to the SERVICE clearances shown in FIG.’s 1-1
and 1-2. For spaces that do NOT supply this clearance,
provide two openings as shown in FIG. 1-1. Each
opening must provide one square inch free area per
1,000 Btu/hr of boiler input.
Recommended service clearances
FRONT - 30" (762 mm)
TOP - 18" (610 mm)
REAR - 24" (610 mm)
FTXL in same space with other gas or oil-fi red
appliances
1. Follow the National Fuel Gas Code (U.S.) or CSA B149.1
(Canada) to size/verify size of the combustion/ventilation
air openings into the space.
The space must be provided with
combustion/ventilation air openings
correctly sized for all other appliances
located in the same space as the FTXL.
Do not install the boiler in an attic.
Failure to comply with the above warnings
could result in severe personal injury,
death, or substantial property damage.
2. Size openings only on the basis of the other appliances in
the space. No additional air opening free area is needed
for the FTXL because it takes its combustion air from
outside (direct vent installation).
Do not install the boiler on carpeting even
if foundation is used. Fire can result,
causing severe personal injury, death, or
substantial property damage.
If fl ooding is possible, elevate the boiler suffi ciently to prevent
water from reaching the boiler.
Flooring and foundation
Flooring
The FTXL is approved for installation on combustible
fl ooring, but must never be installed on carpeting.
Residential garage installation
Precautions
Take the following precautions when installing the appliance
in a residential garage. If the appliance is located in a
residential garage, it should be installed in compliance with
the latest edition of the National Fuel Gas Code, ANSI Z223.1
and/or CAN/CGA-B149 Installation Code.
• Appliances located in residential garages and in
adjacent spaces that open to the garage and are not part
of the living space of a dwelling shall be installed so that
all burners and burner ignition devices are located not
less than 18 inches (46 cm) above the fl oor.
• The appliance shall be located or protected so that it is
not subject to physical damage by a moving vehicle.
Vent and air piping
The FTXL requires a special vent system, designed for
pressurized venting.
The boiler is to be used for either direct vent installation or
for installation using indoor combustion air. When room
air is considered, see the General Venting Section. Note
prevention of combustion air contamination below when
considering vent/air termination.
Vent and air must terminate near one another and may be
vented vertically through the roof or out a side wall, unless
otherwise specifi ed. You may use any of the vent/air piping
methods covered in this manual. Do not attempt to install the
FTXL using any other means.
Be sure to locate the boiler such that the vent and air piping
can be routed through the building and properly terminated.
The vent/air piping lengths, routing and termination method
must all comply with the methods and limits given in this
manual.
Prevent combustion air contamination
Install air inlet piping for the FTXL as described in this
manual. Do not terminate vent/air in locations that can allow
contamination of combustion air. Refer to Table 1A, page
10 for products and areas which may cause contaminated
combustion air.
You must pipe combustion air to the boiler
air intake. Ensure that the combustion air
will not contain any of the contaminants
in Table 1A, page 10. Contaminated
combustion air will damage the boiler,
resulting in possible severe personal injury,
death or substantial property damage. Do
not pipe combustion air near a swimming
pool, for example. Also, avoid areas
subject to exhaust fumes from laundry
facilities. These areas will always contain
contaminants.
