within a solid-fuel burning fi replace and chimney.
The appliance must not be connected to a chimney fl ue
serving a separate solid-fuel burning appliance.
Requires an 1156CLA Valor Co-Axial-to-Co-Linear
appliance adapter, two lengths of 2-ply fl exible
chimney liner, one 3” diameter liner for intake and one
4”diameter liner for exhaust, both approved for venting
gas appliances, a 3 x 4 co-linear termination kit and
