W415-1117 / A / 03.11.1430IOMIOM11.2 CONDENSATE DRAINS11.3 PREPARATIONS FOR VENT AND DRAINING OPTIONH16.2.1ANOTE: It is recommended that pliers be used to firmly clamp the plastic hose clamps.The furnace may condense as much as a 4½ pounds of water per hour (approximately 2 imperial quarts, 2½ U.S.quarts or 2¼ liters). It is necessary to make provisions for draining the condensate away. The furnace is suppliedwith a drain trap assembly. See Figures 16-18 for possible locations of the drain trap.Affix the condensate trap assembly to the interior of the side panel in the blower compartment for upflowpositions. For horizontal positions affix the condensate trap assembly to the exterior side panels.Three plastic drain hose clamps are provided in the parts bag. The large ones are used for securing the drainhose to the front manifold cover drain outlet, and securing the drain hose to the 5/8” barbed fitting on thecondensate trap assembly. The small one is used to secure the drain hose to the 1/2” barbed fitting on thecondensate trap assembly.The drain coupling on the exhauster will work better if the drain holes are pointed down about 15 degrees. Thedrain hose supplied with the furnace is long enough to reach either side panel; however, it must be cut to fit eachapplication. This is to prevent kinking in the drain lines.H16.3.1ABARB FLANGE1. Determine the most suitable vent and drain options for installation. See Figures 16-18 for reference, andrefer to Exhauster Rotation Instructions section if necessary.2. Remove the 3½” plastic exhaust vent cap (if required), and cover vent hole not in use. Install rubbergrommet (in parts bag) for 2” vent pipe. Connect vent pipe (field supplied). If using 1½” or 3” vent, maketransition as close as possible to the unit and on a vertical section.3. Connect 2” air intake pipe (field supplied). The exhaust vent must be supported appropriately prior toit being fitted to the exhauster. Under no circumstances shall the exhauster bear any weight of theventing system.4. Remove the plastic air inlet cap and connect the 2” PVC air intake connector with the rubber gasket on theoutside of the unit using the 2” lock nut (in parts bag).5. Remove the two plastic caps attached to the blower division, and the one attached to the side panel ifapplicable.6. Affix the condensate trap assembly to the interior of the side panel in the blower compartment for upflowpositions using the two screws provided in parts bag (Fig.16). For horizontal positions affix the condensatetrap assembly to the exterior side panels (Fig. 17 & 18).7. Make sure combustion compartment is fully sealed.NOTE• Condensate drain tubing must be cut toappropriate length and slopping towardscondensate trap, ensuring that drain hosesdo not create traps prior to the condensatetrap assembly.• Condensate trap must be primed withwater prior to initial furnace start up.• Any increase of venting diameter must bedone on the vertical sections NOT on thehorizontal sections.NOTEBarbed fittings must be fully inserted intocondensate trap, seated to barb flange.
