1. Flexible UL1777 listed venting may be used in any venting application where rigid direct vent compo-

nents can be used. All restrictions, clearances and allowances

that pertain to the rigid piping apply to the flexible venting.

Flex kits may not be modified. Flex kits may be added to the

end of a vent run made of rigid vent sections using pipe

manufacturer's approved flex to pipe adapters. This may

occur only if doing so does not violate any of the vent-

ing length, height, routing, horizontal to vertical ratio

requirements or clearance considerations detailed

in this manual.

attach flex venting to the appliance starting collar. It

includes 4" inner and 7" outer adapter rings. Figure

wise damage flexible venting.
