GENERAL VENTING
These models are approved for use with DESA
58 Series, rigid type direct vent pipe as supplied
by DESA or with approved types of flexible vent
pipe (not supplied) when appropriate sized for an
8" outer and 5" inner diameter application.
Your fireplace is approved to be vented either
through the side wall, or vertically using the fol-
lowing guidelines:
• Only use DESA supplied or approved types
of venting components or kits. Do not mix
different types of vent components, modify
vent components or custom fabricate vent
components for use in any one installation.
• Minimum clearance between vent pipes and
combustible materials is 1", except where stated
otherwise.
• Combustible material may be flush with the top
front of fireplace with a maximum thickness
of 3/4".
• Do not recess venting terminals into a wall
or siding.
• Do not install vent terminals below grade level.
Maintain a minimum height of 12" above snow
line.
• Do not terminate venting system into an attic
or garage.
• If using a venting configuration of only hori-
zontal venting with no vertical run, a 1/4" rise
for every 12" of run toward the termination is
required.
• There must not be any obstruction such as
bushes, garden sheds, fences, decks, or util-
ity buildings within 24" from the front of the
termination cap.
• Do not locate termination cap where excessive
snow or ice build up may occur. Be sure to clear
vent termination area after snow falls to prevent
accidental blockage of venting system. When
using snow blowers, do not direct snow towards
vent termination area.
VENT TERMINATION CLEARANCES
The final position of your appliance depends on
the location of the vent termination in relation to
the clearances that must be observed as shown in
Figure 14, page 10.
You may avoid extra framing by positioning your
fireplace against an already existing framing mem-
ber. The back of the fireplace may be positioned
directly against a combustible wall.
