If the type of gas does not correspond to the type to be used (natural or LP Gas), it must be converted to the correct type of gas. It is necessary to do the following two operations: 1. Remove and change the pilot orifice with the correct gas type as shown below. 2. Remove and change the burner orifice with the correct gas type as shown below. 3. Remove and change the gas valve with the correct gas type as shown below. Gas Type Orifice Part Numbers Gas Valve Natural Burner Orifice: JGLL051; Pilot Orifice: JGLL064 JVLV023 Propane (LP Gas) Burner Orifice: JGLL070; Pilot Orifice: J12160880 JVLV024 4 Figure 1 1 = Fixed/Closed 2 = Openable V = Vent Terminal A = Air Supply Outside Location for Vent Terminal Upon delivery, check to make sure the packaging has not been damaged. 1. Remove the furnace from box/packaging taking care not to damage the paper template. This is to be used to mark the holes for mounting the furnace. 2. After marking where the appropriate holes will be using the above mentioned template, make a 6-inch (152.4 mm) diameter hole. 3. Cut the combustion exhaust and fresh air inlet tubes according to the wall thickness: Air inlet tube length = wall thickness + 11/16 in. (14.4 mm) F Flue outlet tube length = wall thickness + 3 in. 9/16 (90.5 mm) 4. Drill the mounting holes “A” (5 holes) in the wall. If the wall can receive self–tapping screws, drill 1/8-inch diameter holes. If not, drill 1/4-inch diameter holes and use the plastic anchors provided. A. Clearance above grade, veranda, porch, deck or balcony 12-inches (30 cm) minimum. (3) B. Clearance to window or door that may be opened 12- inches (30 cm) minimum. (3) C. Clearance to permanently closed window (minimum 12- inches (30 cm) recommended to prevent condensation on window. D. Vertical clearance to ventilated soffit located above the terminal within a horizontal distance of 2 feet (60 cm) from the centerline of the terminal 18-inches (46 cm) minimum. E. Clearance to unventilated soffit 12-inches (30 cm) minimum clearance to vinyl soffit 36-inches (90 cm) minimum. F. Clearance to outside corner 12-inches (30 cm) minimum. G. Clearance to inside corner 18-inches (46 cm) minimum. H. Not to be installed above a meter/regulator assembly within 3 feet (90 cm) horizontally from the centerline of the regulator. (3) I. Clearance to service regulator vent outlet 6 feet (1.8 m) minimum. (3) J. Clearance to nonmechanical air supply inlet to building or the combustion air inlet to any other furnace 12- inches (30 cm) minimum. (3) K. Clearance to a mechanical air supply inlet 6 feet (1.8 m) minimum. (3) L. Clearance (1) above paved sidewalk or a paved driveway located on public property 7 feet (2.1 m) minimum. (3) M. Clearance under veranda, porch, deck or balcony 12- inches (30 cm) minimum. (2), (3) Notes: (1) A vent shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings. (2) Only permitted if veranda, porch, deck or balcony is fully open on a minimum of two sides beneath the floor. (3) As specified in CGA B149 installation codes (1991). Note: Local codes or regulations may require different clearances. 5 5. Place the insulating sheet on the support bracket and attach the bracket with insulation to the wall by tightening the five screws with washer. (Figure 3) Be sure the bracket is horizontal. 6. Remove the casing from the furnace body, unscrewing the two mounting screws. (Figure 3) 7. Mount the largest tube (diameter 4-inches (101.6 mm) and the gasket on the unit frame with the screws provided. Insert the smallest tube (diameter 2.-inches, 63.5 mm) in the combustion chamber. (Figure 4) Figure 2 Figure 3 A + 17.4 mm A + 90.5 mm O 63.5 O 101.6 O 152.4 mm Figure 4 Figure 5 6 8. Position the furnace on the wall inserting the inlet/outlet flue in the hole previously drilled. Make sure that the edges of the support bracket perfectly match the existing holes in the back on the unit (Figure 5) 9. Attach the furnace to the support bracket with the two screws provided. During this operation make all necessary adjustments to have a correct installation of the unit (Figures 5 and 6) 10. Reinstall the external casing by tightening the relevant screws (Figure 3). 11. On the external side of the wall, install the protection plate in such a way that the center of the hole in the plate matches the center of the hole in the wall. First place the plate in the right position and mark the holes on the wall. Then, remove the plate and drill the holes in the wall. If the wall can receive self–tapping screws, drill 1/8-inch diameter holes. If not, drill 1/4-inch diameter holes and use the plastic anchors provided. Reposition the plate and fix it onto the wall with the four screws provided. (Figure 7 - Left) 12. Mount the vent cap on the flue pipe and fix it onto the external plate with the three self–tapping screws provided. (Figure 7 - Right) 13. Connect the gas supply line. A gas tap ju...
