Boiler location

Installations must comply with:
• Local, state, provincial, and national codes, laws, regulations
and ordinances.
• National Fuel Gas Code, ANSI Z223.1/NFPA 54 - latest edition.
• National Electrical Code, ANSI/NFPA 70 - latest edition.
Canadian installations must comply with the Natural Gas
and Propane Installation Code, CAN/CSA B149.1 or B149.2
Installation Codes.
• Where required by the authority having jurisdiction, the
installation must conform to the Standard for Controls and
Safety Devices for Automatically Fired Boilers, ANSI/ASME
CSD1.
The ECO boiler gas manifold and controls met safe
lighting and other performance criteria when boiler
underwent tests specified in ANSI Z21.13 — latest edition.
Before mounting the boiler, check:
1. Wall construction — Make sure the wall construction is suitable
to carry the weight of the boiler and components. See page 10
for instructions.
2. A floor stand kit is available. See "BOILER ACCESSORIES"
on page 115 for part number. See kit instructions for details.
3. The boiler is suitable for INDOOR installation only.
4. Check for nearby connection to:
• System water piping
• Venting connections
• Gas supply piping
• Electrical power
• Condensate drain
5. Check area around boiler. Remove any combustible materials,
gasoline and other flammable liquids.
Failure to keep boiler area clear and free of combustible
materials, gasoline and other flammable liquids and
vapors can result in severe personal injury, death or
substantial property damage.
6. The ECO boiler must be installed so that gas control system
components are protected from dripping or spraying water or
rain during operation or service.
7. If new boiler will replace existing boiler, check for and correct
system problems, such as:
• Sediment or corrosion in system piping — clean and flush
piping BEFORE connecting the new boiler. See page 79.
• 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.
Residential garage installation
Precautions
1. Take the following special precautions when installing the boiler
in a residential garage. If the boiler is located in a residential
garage:
• Mount the boiler with its burner and igniter are at least
18 inches above the floor. Follow the National Fuel Gas
Code, ANSI Z223.1 for U. S. installations, or Natural Gas
and Propane Installation Code, CSA B149.1 and B149.2 for
Canadian installations.

AS FIRED WATER BOILER
— Boiler Manual
• Locate or protect the boiler so it cannot be damaged
by a moving vehicle.
• Ensure that the installation complies with all applicable
codes.
• Prevent boiler water and condensate from freezing.
Provide air openings to room
ECO boiler alone in boiler room
1. No air ventilation openings into boiler room are needed if
clearances around boiler are at least equal to the SERVICE
clearances shown in Figure 1, page 9.
2. For spaces that DO NOT supply the minimum
service clearances, provide two openings as shown in
Figure 1, page 9. Each opening must provide 1 square inch
free area per 1,000 Btuh of boiler input.
ECO boiler in same space with other gas or
oil-fired appliances
1. Follow the sizing requirements shown in Figure 25, page 27.
The space must be provided with combustion/
ventilation air openings correctly sized for all
appliances located in the same space as the
ECO boiler.
Reinstall boiler jacket door after servicing.
The boiler jacket door must be securely
fastened to the boiler to prevent boiler from
drawing air from inside the boiler room. This
is particularly important if the boiler is located
in the same room as other appliances.
Failure to comply with the above warnings
could result in severe personal injury, death
or substantial property damage.
Vent and air piping
1. The ECO boiler requires a special vent system, designed for
pressurized venting. ECO boilers are rated ANSI Z21.13
Category IV (pressurized vent, likely to condense in the
vent). See instructions beginning on page 22.
2. You must also install air piping from outside to the boiler
air intake adapter. The resultant installation is categorized
as direct vent (sealed combustion). Note prevention
of combustion air contamination on page 22 when
considering vent/air termination.
3. Vent and air must terminate near one another unless
otherwise specified in this manual. Vent and air piping
may be routed vertically through the roof or out a side
wall, following the options give in this manual. You may
use any of the vent/air piping methods covered in this
manual. Do not attempt to install the ECO boiler using
any other means.
4. 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 in instructions beginning on page 22.
