2 General venting

Optional room air

Applications utilizing the SYNC boiler may be installed with a single pipe carrying the flue products to the outside while using combustion air from the equipment room. In order to use the room air venting option the following conditions and considerations must be followed.

The unit MUST be installed with the appropriate room air inlet cover (factory installed).

The equipment room MUST be provided with properly sized openings to assure adequate combustion air. Please refer to instructions provided with the room air kit.

There will be a noticeable increase in the noise level during normal operation from the inlet air opening.

Using the room air configuration makes the unit vulnerable to combustion air contamination from within the building. Please review Section 1, Prevent Combustion Air Contamination, to ensure proper installation.

Vent system and terminations must comply with the standard venting instructions set forth in this manual.
