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.
Electrical installation and grounding must be in
accordance with CSA C22.1, Part 1, Canadian Electrical
Code, and/or local codes.
For Canada only: CAN/CSA B149.1, Natural Gas and
Propane Installation Code, and any local 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 CSD-1.
The boiler gas manifold and controls met
safe lighting and other performance criteria
when boiler underwent tests specified in
ANSI Z21.13 – latest edition.
Before locating the boiler, check:
1. The can be floor-standing with optional kit or
boiler
wall mounted.
2. Wall construction — If the boiler is wall-mounted,
make sure the wall construction is suitable to carry
the weight of the boiler and components. See page 10
for instructions.
3. The boiler is suitable for INDOOR installation only.
4. Check for nearby connection to:
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 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 97.
System leaks causing oxygen corrosion or heat ex-
changer 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
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.
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.
Combustion air requirements
The ECO Tec boiler is certified as a=- Direct Vent appliance. It can be converted
to Direct Exhaust by using the Approved Weil-McLain Direct Exhaust kit.
Direct vent (sealed combustion) where combustion air is ducted from
outdoors.
Direct exhaust where combustion air is obtained directly from the
boiler room.
Provide air openings to room
ECO Tec
1. No air ventilation openings into boiler room are needed if Direct vent and
clearances around boiler are at least equal to the SERVICE clearances shown
in Figure 1, page 8.
2. For spaces that DO NOT supply the minimum service clearances, provide
two openings as shown in Figure 2, page 8. Each opening must provide
1 square inch free area per 1,000 Btuh of boiler input.
The space must be provided with combustion/
ventilation air openings correctly sized for all
appliances located in the same space as the
ECO Tec 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.
ECO Tec
Follow the sizing requirements shown in Figure 29, page 26.
Vent and air piping
1. The boiler requires a special vent system, designed for pressurized
venting. The boilers are rated ANSI Z21.13 Category IV (pressurized vent,
likely to condense in the vent). See instructions beginning on page 20.
2. You must also install air piping from outdoors to the boiler air intake
adapter. The resultant installation is categorized as direct vent (sealed
combustion). Note prevention of combustion air contamination on page 20
when considering vent/air termination.
3. Direct exhaust venting can be done with the approved Weil-McLain Direct
Exhaust Kit, please see page 137 for kit information
4. 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 given in this manual. You may use
any of the vent/air piping methods covered in this manual. Do not attempt
to install the boiler using any other means.
5. 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 20.
