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.
*Check with local codes or with the CANCGA B149 (.1 or .2) Installation Codes for Canada for Installations. In the USA, follow the current National Fuel Gas Fuel Gas Code, ANS Z223.1 also known as NFPA 54.
