DV425TR DIRECT VENT ROOM HEATER
HORIZONTAL INSTALLATION, cont.
Step 1.
Determine the desired location of the stove. Check to ensure that wall studs or roof rafters are not in the way when the venting system is attached. If this is the case, you may want to adjust the location of the stove.
Step 2.
Simpson Dura-Vent pipe is designed with special twist-lock connections. To connect the venting system to the stove flue outlet, a twist-lock adapter is built into the stove at the factory. Remember to include wall thickness in minimum clearances when figuring the measurements for your installation needs.
Note: Twist-lock procedure: Four indentations, located on the female ends of pipes and fittings, are designed to slide straight onto the male ends of adjacent pipes and fittings by orienting the four pipe indentations so they match and slide into the four entry slots on the male ends, see Fig. 5 below. Push the pipe sections completely together, then twist-lock one section clockwise approximately one-quarter turn, until the two sections are fully locked. The female locking lugs will not be visible from the outside, on the pipe or fittings. They may be located by examining the inside of the female ends.

NOTES:
Horizontal runs of vent must be supported every 3’ (914mm). Wall straps are available for this purpose. Horizontal sections require a 1/4" (6mm) rise for every 12" (305mm) of horizontal travel.
Exterior Vent Diameter = 6 5/8" (177mm); Inner Vent Diameter = 4" (101mm)
