10W415-0662 / C / 04.11.123.1 VENTING LENGTHS AND COMPONENTSUse only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab ventingcomponents. Minimum and maximum vent lengths, for both horizontal and vertical installations, and air terminallocations for either system are set out in this manual and must be adhered to. For Simpson Dura-Vent, Selkirk DirectTemp, American Metal Amerivent and Metal-Fab follow the installation procedure provided with the venting components.A starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installationprocedure found on the website for your venting supplier.For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed using a redhigh temperature silicone (RTV). This same sealant may be used on both the inner exhaust and outer intake vent pipejoints of all other approved vent systems except for the exhaust vent pipe connection to the appliance flue collar which mustbe sealed using the black high temperature sealant Mill Pac. High temperature sealant must be ordered separately.When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the followingtermination kits: wall terminal kit GD222, GD222R, or 1/12 to 7/12 pitch roof terminal kit GD110, 8/12 to 12/12 roof terminalkit GD111, flat roof terminal kit GD112 or periscope kit GD201 (for wall penetration below grade). With flexible venting, inconjunction with the various terminations, use either the 5 foot vent kit GD220 or the 10 foot vent kit GD330.For optimum flame appearance and appliance performance, keep the vent length and number of elbows to a minimum.The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify thatit is unobstructed and undamaged.Rigid and flexible venting systems must not be combined. Different venting manufacturer components must notbe combined.These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal run is 20feet. The maximum allowable vertical vent length is 40 feet. The maximum number of vent connections is two horizontallyor three vertically (excluding the appliance and the air terminal connections) when using flexible venting.PART 4”/7” SUPPLIER WEBSITEDuravent W175-0053 Wolf Steel www.duravent.comAmerivent 4DSC-N2 American Metal www.americanmetalproducts.comDirect Temp 4DT-AAN Selkirk www.selkirkcorp.comSuperSeal 4DNA Metal-Fab www.mtlfab.com8.1For optimum performance, it is recommended that all horizontal runs have a 1/4" rise per foot when usingSimpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Wolf Steel rigid vent components and aminimum 1" rise per foot when using Wolf Steel flexible vent components.
