DVP Venting System
These venting system components have been tested for use with approved HHT Direct Vent appliances. Check with your
local building code agency before you begin installation to ensure compliance with local codes, including the need for per-
mits and follow-up inspections. If you encounter any problems regarding code approvals, or if you need clarification of any
of the instructions contained here, contact your Hearth & Home Technologies dealer. For the dealer nearest you, please

A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
• Between ceiling firestops
• Between wall shield firestops
• Around vent system
Failure to keep insulation or other material away from vent
pipe may cause over heating and fire.
Refer to appliance installation manuals for clearances.
B. Wall Penetration Framing
• Wherever a combustible wall is penetrated, the hole
must be framed and a wall shield installed. When a wall
is penetrated the wall shield is only required on one side
and no heat shield is necessary. If your local inspector
requires a wall shield on both sides, then both wall
shields must have a heat shield attached to them. These
shields maintain minimum clearances and restrict cold air
infiltration.
• If the wall being penetrated is of noncombustible materials
(material which will not ignite or burn, or has a UL fire
rating of zero), a hole 1 in. (25 mm) larger in diameter
than the pipe is acceptable.

CAUTION! Risk of Cuts/Abrasions. Wear protective
gloves and safety glasses during installation. Sheet metal
edges are sharp.
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38mm). The
heat shield is designed to be used on a wall 4 in. to 7-1/4 in. (102
mmto 184 mm) thick. If wall thickness is less than 4 in. (102 mm) the
existing heat shields must be field trimmed. It wall thickness is greater
than 7-1/4 in. (184mm) a DVP-HSM-B will be required.
