1 Determine boiler location (continued)
Provide air openings to room:
The SYNC alone in boiler room
1. No air ventilation openings into the boiler room are
needed when clearances around the SYNC 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.
2. Combustion air openings are required when using the
Room Air Option on page 24 of this manual.
The SYNC in same space with other gas or oil-fired
appliances
1. Follow the National Fuel Gas Code (U.S.) or CSA B149.1
and B149.2 (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 SYNC.
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 SYNC 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 flooding is possible, elevate the boiler sufficiently to prevent
water from reaching the boiler.
Flooring and foundation
Flooring
The SYNC is approved for installation on combustible
flooring, but must never be installed on carpeting.
Vent and air piping
The SYNC requires a special vent system, designed for
pressurized venting.
You must also install air piping from outside to the boiler air
intake adapter. The resultant installation is direct vent (sealed
combustion). 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. You may
use any of the vent/air piping methods covered in this
manual. Do not attempt to install the SYNC 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 SYNC 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.
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.
