8312.11 - Sidewalltermination – Concentricvent12.11.1 - Description and usageThe termination kit must terminate outside thestructure and must be installed as shown inFigure 12-19.The required concentric termination kit as well ascombustion air and vent pipe materials are listedin Figures 12-7 and 12-8.The termination ending must be protected fromrain, see Figure 12-20.12.11.2 - Sidewall terminationinstallation1. Determine the best location for the terminationkit (see Figures 12-19 and 12-20).2. The total length of piping for vent or air mustnot exceed the limits given in Section 12.3.3. You must consider the surroundings whenterminating the vent and air:a. Position the vent termination where vaporswill not damage nearby shrubs, plants or airconditioning equipment or be objectionable.b. The flue products will form a noticeableplume as they condense in cold air. Avoidareas where the plume could obstructwindow views.c. Prevailing winds could cause freezing ofcondensate and water/ice buildup whereflue products impinge on building surfacesor plants.d. Avoid possibility of accidental contact of flueproducts with people or animalse. Do not terminate above any door or window.Condensate can freeze, causing iceformations.f. Locate or guard vent to prevent condensatedamage to exterior finishes.4. Cut one (1) hole 5 inch diameter into thestructure to install the termination kit.5. Install the Concentric vent kit following theconcentric kit manufacturer’s instruction.NOTICE! Ensure termination location clearancedimensions are as shown in Figures 12-19 and12-20.CAUTION!!! DO NOT use field-suppliedcouplings to extend pipes. Airflowrestriction will occur and may causeintermittent operation.6. Operate the appliance one (1) heat cycle toensure combustion air and vent pipes areproperly connected to the concentric venttermination connections.12 - INSTALLATION - CATEGORY IV: Vent and combustion airFigure 12-19 Concentricsidewall termination clearancesOverhang or roofGrade / snow lineVentCombustion airintakeFigure 12-20 Concentric sidewalltermination clearances
