Minimum Clearance and Framing
Model DT has a 1" minimum airspace clearance to
combustibles requirement when used as L Vent. This applies
whether DT is being used to bring outside air to the pellet
appliance or not. Do not fill this space with insulation or any
other material. The airspace is required for the safe operation
of the vent. Model UPP has a clearance to combustibles
requirement of 1".
"Combustibles" include framing lumber, drywall, plaster,
plywood, paneling and other building materials.
For penetrating walls, ceiling joists or roof joists the required
framing dimensions for Model DT are 8-5/8" x 8-5/8". This
will provide a 1" clearance for a properly centered vent. A
Wall Thimble is available with framing dimensions of 8-3/4".
NOTE: While these instructions focus on proper installation
of DT when outside air is being drawn to appliance, if other
sources of combustion air are provided, DT may be used
with the combustion air passageway blocked, still at 1"
airspace clearance.
