These instructions apply to Kit #3265 OSA Termination Kit. ST528 Fig. 1 Outside Air Duct components. Consult your local, state or town building codes before installation. Carpentry and metal work will be required as you install your stove. Wear gloves and protective eyewear. ST528 Mobile Home Outside Air Kit 11/21/00 djt Tools required: • Scissors • Flat and Phillips screwdriver • Electric drill and bits • Saws for cutting floor and wall openings Locate the Outside Air Duct Opening Determine the layout of your installation prior to beginning construction. (Figs. 2 or 3) You may choose the location for the floor or wall opening after positioning the stove. Select a location for the floor opening that does not require weakening structural members. Exterior Wall KT560 Fig. 2 Outside air through the wall installation. The air duct must pass through an exterior wall to an air source outside the house. Prepare the Stove Before installing the duct work for this kit, remove the stove’s bottom heat shield if it is installed. Remove the outside air connection cut out (Fig. 4) in the shield by pushing gently on one of the free edges of the cutout circle. Rotate the disk until it breaks free. Be sure to wear protective gloves to avoid being cut by the sheet metal edges. The bottom heat shield must be reinstalled before attaching the outside air kit duct work to the bottom of the stove.

Make sure you are compliant with local and state building codes for firebreaks and any other building requirements. Test fit the 3” diameter air duct to see that it will pass through the wall system. 4. Attach the exterior sealing plate to the exterior wall with the screws provided. To provide a tight seal, place a bead of silicone sealer on the side of the plate next to the home, and also around the pipe where it passes through the sealing plate. 5. Attach the rodent screen to the outside of one of the non-crimped ends of a 3” diameter air duct using the hardware provided. 6. Bend the tabs outward on the exterior sealing plate where the duct passes through. Slide the duct, with the rodent screen attached, through the exterior sealing plate and secure accordingly through the holes on the bent tabs. 7. From inside the house, attach the interior trim collar by sliding the collar over the 3” diameter air duct and fasten it to the wall. 8. Complete your installation by either using the remaining 3” diameter air duct or 3” diameter flexible aluminum pipe. Use the two (2) hose clamps included with the kit to attach the ducts together. NOTE: If you decide to use the 3” diameter air duct, provided it is long enough, you will have to measure and cut the duct accordingly. Outside Air Through the Floor Installation KT501 Fig. 5 Gasketing applied to air duct elbow. 2. Insert air duct elbow with applied gasketing through the hole in the bottom heat shield and into the iron outside air housing which is located under the stove at the rear. (Fig. 6) Adjust the angle of the duct as necessary. Mark the location of the screw hole, using the hole in the iron housing as a guide. Using a power drill, drill a 1/8” (3 mm) hole through the air duct using the hole in the housing and secure the duct with one (1) #10 x 1/2” pan head screw. KT501 elbow 7/04 Outside Air Housing Cast into Bottom of Stove Air Duct Elbow #10 x 1/2” Screw KT500 Fig. 6 Outside air housing with air duct elbow installed. 2 1. Locate the center of the outside air housing on the floor and cut a hole for the 3” diameter air duct to pass through. Make sure you are compliant with local and state building codes for firebreaks and any other building requirements. You must cut through the floor protection that is or will be placed under the stove as well. Test fit the 3” diameter air duct to see that it will pass through the floor system. 2. Determine the length and cut the 3” diameter air duct by leaving enough duct below the floor system to be able to install the 3” diameter elbow as shown in Figure 3. 3. Insert the 3” duct through the hole in the floor so the non-crimped end is toward the stove (above the floor). From the stove side of the floor system, slide the interior trim collar over the 3” diameter air duct. Using the #10 x 1/2” screws provided, secure the interior trim collar to the finished floor. 4. Apply approximately 11¹⁄₂” (292 mm) of gasketing around the 3” (76 mm) diameter air duct along the perimeter of the non-crimped edge. (Fig. 7) 3” Air Duct Gasket KT496 Fig. 7 Gasketing applied to 3” diameter air duct. 5. Position (or reposition) the stove so the 3” duct is aligned with the outside air connection collar and heat shield pass-through hole. Insert the 3” diameter air duct with applied gasketing through the bottom heat shield hole and intoKT496 the iron outside air housing. (Fig. 8) Using a power drill, drill a 1/8” (3 mm) hole gasket pipe through the air duct using the hole to in the housing as a guide and secure it7/04 with one (1) #10 x 1/2” pan head screw. Outside Air Housing 6. Attach the 3” diameter elbow to the bottom of the 3” diameter air duct connected to the stove using one (1) of the hose clamps provided with the kit. 7. Locate and cut a hole opening on the exterior wall. Make sure you are compliant with local and state building codes for firebreaks and any other building requirements. Test fit the 3” diameter air duct to see that it will pass through the wall system. 8. Attach the exterior sealing plate to the exterior of the home with the screws provided. To provide a tight seal, place beads of silicone sealer on the surface of the plate against the home and around the pipe where it passes through the sealing plate. 9. Attach the rodent screen to the outside of the noncrimped end of the 3” diameter air duct using the hardware provided. 10. Bend the tabs outward on the exterior sealing plate where the duct passes through. Slide the duct, with the rodent screen attached, through the exterior seal plate and secure accordingly through the holes on the bent tabs. 11. Complete your installation by using the 3” diameter flexible aluminum pipe to connect the end of the 3” diameter elbow to the end of the 3” diameter air duct. Use the two (2) hose clamps included with the kit to attach the ducts together. 3” Air Duct KT497 Fig. 8 Outside air housing with 3” diameter air duct installed.
