Anleitung Zusammenfassung
• These vent kits allow for either horizontal or vertical venting of the stove. • The maximum number of 4" fl exible connections is 3 horizontally or three vertically (excluding the stove and the air terminal connections). • When terminating vertically, the minimum vertical rise is 3 feet above the stove and the maximum vertical rise is 40 feet. FIGURE 4. Deviation from the minimum vertical vent length can create diffi culty in burner start-up and/or carboning. Use an adjustable pipe as the fi nal length of rigid piping to the stove for ease of installation. FIGS 6a-b FIGURE 5 HORIZONTAL RUN NOT TO EXCEED VERTICAL RISE • For optimum fl ame appearance and stove performance, keep the vent length and number of elbows to a mini mum. • The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged. The maximum horizontal run with a 57 inch vertical rise immediately above the stove is 20 feet . FIGURES 6a-b. VENTING VENTING LENGTHS & AIR TERMINAL LOCATIONS For optimum performance, it is recommended that all horizontal runs have a minimum . inch rise per foot. 16 INCHES 3 FEET MINIMUM 40 FEET MAXIMUM FIGURE 4 24” MAX TYPICAL CORNER INSTALL WITH ZERO RISE 10 W415-0547 / B / 05.08.06 USE GD201 PERISCOPE KIT BELOW GRADE INSTALLATION MAXIMUM 10FT VENT LENGTH OF HORIZONTAL REGARDLESS VENT LENGTH 24" MINIMUM 12"MINIMUM Use the GD201 periscope kit to locate the air termination above grade. The periscope must be installed so that when fi nal grading is completed, the bottom air slot is located a minimum of 12 inches above grade. The maximum allowable vent length depends on the fi replace, as illustrated.
