Zero Clearance Applications

An alternate air supply is recommended with
this component.
For installation other than in existing woodburning fireplaces
such as new construction or renovation projects, a Zero
Clearance Kit must be used. ��he kit enables these inserts
to be installed in combustible environments. Whenever
using a Zero Clearance Kit, consideration must be given to
the dimensions of the Zero Clearance Kit and the require-
ments of the Air Kit.
NOTE: If a Zero Clearance Kit is required for models
LHECDV20/LHERDV20/LHECDV30/LHERDV30 Direct
Vent Inserts, only the Vermont Castings Group zero
clearance kit HEZC combined with the HEDVCAK is
approved to be used. Refer to Page 9, figure 10 for HED-
VCAK chimney adapter kit installation. When using the
HEZC with insert models LHECDV20 or LHERDV20, the
Trim Closure Kit, LHE20TCK, must also be installed.
