W415-1367 / B / 01.09.19EN8venting2.0 ventingFor horizontal and vertical vent runs that pass through unheated spaces (attics, garages, crawl spaces) it isrecommended they be insulated with the insulation wrapped in a protective sleeve to minimize condensation.Vent lengths terminating vertically should be kept to short lengths (maximum 5ft / 1.5m) in areas with colderclimates, especially in installations where the majority of the vent length is to be installed outside the buildingenvelope (such as in the attic).2.1 cold climateThis appliane uses a 3” (76.2mm) exhaust / 5” (127mm) air intake vent pipe system. Refer to the sectionapplicable to your installation.For safe and proper operation of the appliance follow the venting instruction exactly. Deviation from the minimumvertical vent length can create difficulty in burner start-up and/or carboning. Under extreme vent configurations,allow several minutes (5-15) for the flame to stabilize after ignition. Provide a means for visually checking the ventconnection to the appliance after the appliance is installed. Use a firestop, vent pipe shield or attic insulation shieldwhen penetrating interior walls, floor or ceiling.NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructionsprovided for the initial installation.! WARNING• Risk of fire. Maintain specified air space clearances to vent pipe and appliance.• If venting is included with spacers, the vent system must be supported every 3 feet (0.9m) for both verticaland horizontal runs. Use supports or equivalent combustibles. Use Wolf Steel Ltd. support ring assemblyW010-0370 or equivalent non-combustible strapping to maintain the minimum clearance to combustiblesfor both vertical and horizontal runs. Spacers are attached to the inner pipe at predetermined intervals tomaintain an even air gap to the outer pipe. This gap is required for safe operation. A spacer is required at thestart, middle and end of each elbow to ensure this gap is maintained. These spacers must not be removed.2.2 venting lengths and componentsThe vent connection to the appliance can be viewed by removing the baffle from the top, inside of the firebox.Use only Wolf Steel venting components. Minimum and maximum vent lengths, for both horizontal and verticalinstallations, and air terminal locations for either system are set out in this manual and must be adhered to. Useonly Wolf Steel Ltd. flexible vent components with the Wolf Steel Ltd. GD179 termination kit. Thisappliance uses a 3” (76.2mm) diameter exhaust and a 5” (127mm) diameter intake coaxial vent system.All outer pipe joints of these venting systems must be sealed using Red RTV and/or Mill Pac high temperaturesealant (not supplied) hereafter referred to as high temperature sealant W573-0002 (Red RTV) and the hightemperature sealant W573-0007 (Mill Pac).For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed usinga red high temperature silicone (RTV). This same sealant may be used on both the inner exhaust and outer intakevent pipe joints of all other approved vent systems except for the exhaust vent pipe connection to the applianceflue collar which must be sealed using the black high temperature sealant Mill Pac.With flexible venting, in conjunction with the GD178 wall terminal kit, use either the 5 foot (1.5m) vent kit GDT5or the 10 foot (3.1m) vent kit GDT10. These kits allow for extended horizontal venting of the appliance.When using approved Wolf Steel venting components, use only the following termination kits: wall terminal kitGD178, or 1/12 to 7/12 pitch roof terminal kit GDT110, 8/12 to 12/12 roof terminal kit GDT111, flat roof terminalkit GDT112.For optimum flame appearance and appliance performance, keep the vent length and number ofelbows to a minimum. The air terminal must remain unobstructed at all times. Examine the air terminalat least once a year to verify that it is unobstructed and undamaged.Rigid and flexible venting systemsmust not be combined. Different venting manufacturer components must not be combined. Ventterminals shall not be recessed into a wall or siding.These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontalrun is 7 feet (2.1m). The maximum allowable vertical vent length is 19 ½ feet (5.9m). The maximum number of ventconnections is two horizontally or three vertically (excluding the appliance and the air terminal connections) whenusing flexible venting.
