DV Only: Before installing vent liners, mark each liner on both
ends to designate which is the intake and the exhaust.
Measure the height of the chimney beforehand and purchase the
appropriate kit. Never attempt to over-stretch a flexible liner to
accommodate the height of the chimney.

installation of the Sonnet; the smoke shelves, shields and baffles
may be removed if attached by mechanical fasteners.
The chimney must be clean, in good working order and
constructed of non-combustible materials.

permit air to leak into the chimney.

using Adaptor (50-1499 - 2” to 3” Air Intake) included with this unit.
