Installation & Operation Manual

1 Determine boiler location (continued)

Provide air openings to room:

Vent and air piping

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 18 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 (Canada) to size/verify size of the combustion/ventilation air openings into the space.

The SYNC 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 Section 4, Vertical Direct Venting. 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 specified. 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.

￿WARNING

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,

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.

death, or substantial property damage.

￿WARNING

Ensure that the combustion air will not

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).

Flooring and foundation

Flooring

The SYNC is approved for installation on combustible flooring, but must never be installed on carpeting.

￿WARNING 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.

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.
