APPENDIX B1 – Atmospheric Venting

GENERAL WARNINGS for ATMOSPHERIC VENTING SYSTEMS

USE ATMOSPHERIC VENTING only with boilers approved for atmospheric venting as noted in the Specifications Section of this manual.

INSPECT EXISTING CHIMNEY for obstructions and deterioration and repair or line the chimney prior to placing the boiler in service.

UNLINED MASONRY CONSTRUCTION is prohibited for use as a chimney.

FIREPLACES AND FAN-ASSISTED GAS APPLIANCES must not be vented into the same chimney space as this boiler.

DO NOT REDUCE THE DIAMETER of the vent connector between the boiler and the chimney. It must not be smaller than the outlet on the drafthood, damper, or vent reducer supplied with the boiler.

UNLISTED VENT DAMPERS AND OBSTRUCTIONS in the vent pipe are prohibited.

THE VENT DAMPER supplied with the boiler shall not be used to block the vent of any other appliance.

Install vent and vent connector (Figure B-1). Comply with all design and installation requirements in the Connect Venting Section of this manual, local code, and the National Fuel Gas Code or Can/CSA B149.1. Clay flue lined masonry chimneys do not meet the venting requirements for this appliance.
