WARNING

Asphyxiation hazard. The exhaust vent for this fur­ nace must be securely connected to the furnace flue transition at all times.

DO NOT insulate the space between the liner and the chimney wall with puffed mica or any other loose gran­ ular insulating material.

IMPORTANT

SINGLE appliance venting of a fan‐assisted furnace into a tile‐lined masonry chimney (interior or outside wall) is PROHIBITED. The chimney must first be lined with either type B1 vent or an insulated single wall flexible vent lining system which has been sized ac­ cording to the provided venting tables and the vent pipe manufacturer's instructions.

A fan-assisted furnace may be commonly vented into an existing lined masonry chimney if the following conditions are met:

SThe chimney is currently serving at least one drafthood- equipped appliance;

SThe vent connectors and chimney are sized according to the provided venting tables.

If type B1 double‐wall vent is used inside a chimney, no oth­ er appliance can be vented into the chimney. The outer wall of type B1 vent pipe must not be exposed to flue products. A type B1 vent or masonry chimney liner shall terminate above the roof surface with a listed cap or a listed roof as­ sembly according to the terms of their respective listings and the vent manufacturer's instructions.

When inspection reveals that an existing chimney is not safe for the intended purpose, it shall be rebuilt to conform to nationally recognized standards, lined or relined with suitable materials, or replaced with a gas vent or chimney suitable for venting EL180UHE series units. The chimney passageway must be checked periodically to ensure that it is clear and free of obstructions.

Do not install a manual damper, barometric draft regulator, or flue restrictor between the furnace and the chimney. Never connect a Category I appliance to a chimney that is servicing a solid-fuel appliance. If a fireplace chimney flue is used to vent this appliance, the fireplace opening must be permanently sealed.
