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 appropriately sized for an 8"

outer and 5" inner diameter application.

Your fireplace is approved to be vented either hori-

zontally through a side wall, or vertically through

a roofline using the following 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 11, page 9.

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.

*Check with local codes or with the CANCGA

B149.1 or B149.2 Installation Codes for Canada

installations. In the USA, follow the current Na-

tional Fuel Gas Fuel Gas Code, ANS Z223.1 also

known as NFPA 54.
