VENTING INSTALLATION PRECAUTIONS

Consult local building codes before beginning the installation. The installer must make sure to select the proper vent system for installa- tion. Before installing vent kit, the installer must read this fireplace manual and vent kit instructions.

Only a qualified service person should install venting system. The installer must follow these safety rules:

•Wear gloves and safety glasses for protection

•Use extreme caution when using ladders or when on roof tops

•Be aware of electrical wiring locations in walls and ceilings

The following actions will void the warranty on your venting system:

•Installation of any damaged venting component

•Unauthorized modification of the venting system

•Installation of any component part not manufactured or approved by DESA

•Installation other than as instructed by these instructions

3.When installation of vent pipe is complete, in stall vent termi- nation. Depending on the location of your fireplace, you will vent vertically or horizontally.

4.Allow 1" of pipe to protrude from internal wall, depending on wall thickness. See Figure 7.

5.For horizontal installation, an optional siding standoff may be installed between the vent cap and the exterior wall. Secure horizontal vent cap to standoff. Secure standoff/vent cap as- sembly to wall (see Figure 7). Do not seal termination to vent pipe. The vent termination must be removable for service pipe inspection.

6.For vertical installation, a vertical termination is available. Also for vertical venting application, install vertical flue restrictor into inner collar of fireplace as shown in Figure 6.

When installing a length of pipe for vertical termination that is over 3 ft., support the pipe every 3 ft. using metal wall straps. Vertical to horizontal pipe must be kept at a 1 ft. to 4 ft. ratio with a maximum run of no more than 20 ft.
