Determine boiler location

Installation must comply with:
• Local, state, provincial, and national codes, laws,
regulations, and ordinances.
• National Fuel Gas Code, ANSI Z223.1 – latest edition.
• Standard for Controls and Safety Devices for Automatically
Fired Boilers, ANSI/ASME CSD-1, when required.
• National Electrical Code.
• For Canada only: B149.1 Installation Code, CSA C22.1
Canadian Electrical Code Part 1 and any local codes.
The FTXL gas manifold and controls
NOTICE
met safe lighting and other performance
criteria when the boiler underwent tests
specifi ed in ANSI Z21.13 – latest edition.
Before locating the boiler, check:
1. Check for nearby connection to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
2. Locate the appliance so that if water connections should
leak, water damage will not occur. When such locations
cannot be avoided, it is recommended that a suitable
drain pan, adequately drained, be installed under the
appliance. The pan must not restrict combustion air
fl ow. Under no circumstances is the manufacturer to be
held responsible for water damage in connection with
this appliance, or any of its components.
3. Check area around the boiler. Remove any combustible
materials, gasoline and other fl ammable liquids.
Failure to keep boiler area clear and free
WARNING
of combustible materials, gasoline, and
other fl ammable liquids and vapors can
result in severe personal injury, death, or
substantial property damage.
4. The FTXL must be installed so that gas control system
components are protected from dripping or spraying
water or rain during operation or service.
5. If a new boiler will replace an existing boiler, check for
and correct system problems, such as:
• System leaks causing oxygen corrosion or heat exchanger
cracks from hard water deposits.
• Incorrectly-sized expansion tank.
• Lack of freeze protection in boiler water causing system
and boiler to freeze and leak.
6. Check around the boiler for any potential air contaminants
that could risk corrosion to the boiler or the boiler
combustion air supply (see Table 1A on page 10).
Prevent combustion air contamination. Remove any of
these contaminants from the boiler area.
DO NOT install units in rooms or
WARNING
environments that contain corrosive
contaminants (see Table 1A on page 10).
Failure to comply could result in severe
personal injury, death, or substantial
property damage.
Installation & Operation Manual
This appliance is certifi ed as an indoor
WARNING
appliance. Do not install the appliance
outdoors or locate where the appliance will
be exposed to freezing temperatures or to
temperatures that exceed 100°F.
Do not install the appliance where the
relative humidity may exceed 93%. Do not
install the appliance where condensation
may form on the inside or outside of the
appliance, or where condensation may fall
onto the appliance.
Failure to install the appliance indoors
could result in severe personal injury,
death, or substantial property damage.
This appliance requires a special venting
WARNING
system. The vent connection to the appliance
must be made with the starter CPVC/
stainless steel pipe section provided with
the appliance. The fi eld provided PVC vent
fi ttings must be cemented to the CPVC pipe
section. Use only the vent materials, primer
and cement specifi ed in this manual to make
the vent connections. Failure to follow this
warning could result in fi re, personal injury,
or death.
Closet and alcove installations
A closet is any room the boiler is installed in which is less than
171 cubic feet for FTX400 models, 193 cubic feet for FTX500
models, 223 cubic feet for FTX600 models, 247 cubic feet for
FTX725 models and 278 cubic feet for FTX850 models.
An alcove is any room which meets the criteria for a closet with
the exception that it does not have a door.
Example: Room dimensions = 5 feet long, 4 feet wide, and
8 foot ceiling = 5 x 4 x 8 = 160 cubic feet. This would be
considered a closet for a FTXL Boiler.
For closet and alcove installations as shown
WARNING
in FIG.'s 1-1 and 1-2, CPVC or stainless
steel vent material must be used inside
the structure. The ventilating air openings
shown in FIG.'s 1-1 and 1-2 are required
for this arrangement. Failure to follow this
warning could result in fi re, personal injury,
or death.
Provide clearances:
Clearances from combustible materials
1. Hot water pipes—at least 1/4" (6 mm) from combustible
materials.
2. Vent pipe – at least 1" (25 mm) from combustible materials.
3. See FIG.'s 1-1 and 1-2 on page 8 for other clearance
minimums.
Clearances for service access
1. See FIG.'s 1-1 and 1-2 on page 8 for recommended
service clearances. If you do not provide the minimum
clearances shown, it may not be possible to service the
boiler without removing it from the space.
