Note -Installation must conform with these I -External Filter Rack instructions and the installation instructions (Used with kit CAT#16L23 and16L24) packaged with the G26 furnace. 1-Lay G26 unit on its side and cut out return air opening in cabinet. See figure 4. Closet installations -G26 cabinet depth is 2-3/8" 2-Filter rack is shipped for right side installation (60.5ram) larger than G14. The G26 may be installed and for 16 inch (40.6 cm) filter size. If application one inch (25turn) closer to rear of closet (if space requires left side orientation, convert as shown in permits) by rotating supply air transition 180 degrees figure 2. If application requires 20 inch (50.8 cm) from that shown in figure 4 or5. filter size convert as shown in figure 3. Page 3 Note -It is recommended that rack be converted to 20 inch filter size if filter is installed elsewhere in return air duct. 3-In applications where rack uses a 16 inch (50.8cm) filter, remove filler piece before cutting rack opening. See figure 4. 4 -Cut four strips from rollofadhesive-backedfoam tape (provided) to fit filter rack flanges, Apply to flanges. 5 -Secure filter rack to cabinet as shown in figure 4. 6 -Cut opening in filter rack as shown in figure 4, 7 -In applications where rack uses a 16 inch (50,8cm) filter, remove rack from cabinet, re-install filler piece, then re-install rack to cabinet. 8-Install existing filter, unless filter is located elsewhere in the return air duct, 9-Attach door to filter rack with thumb screws provided. II -Internal Filter Rack (Used with kit CAT#16L25) Note -If filter is not to be located inside of unit, installation of this filter kit is not required. 1 -Lay G26 unit on its side and cut out return air opening in cabinet at knockout guides, See G26 installation instructions. 2 -Install filter rack top and bottom inside unit as shown in figure 5, tn right side installations wiring must be carefully worked around. 3 -Install existing filter, 4 -Slide door into filter rack bottom seam and align with filter rack top securing hole. Attach with thumb screws provided. 5-Securewiring awayfrom filter access areawith two provided wire ties. Use existing screws in existing screw locations to prevent accidental damage to control board(s)/wiring by drilling of new holes. B -Supply Air Transition Installation 1 -Cut four strips from roll ofadhesive-backedfoam tape (provided) to fit supply air transition flanges at G26 unit connection. Apply to flanges. See figure 4 or 5, 2-Position supply air transition on unit top as shown in figure 4 or 5. 3-If required, internally insulate transition with foil-faced insulation (field provided) and fasten with kit provided insulation pins and washers, 4-Use four screws and/or bend cabinet flanges over transition tips to secure transition. C -Unit Installation 1 -Align unit with existing supply air plenum (coil cabinet in air conditioning applications) and return air plenum. Note -If required, use existing G14 isomode pads to achieve this alignment. 2 -Make connections to unit, In bottom return air applications, follow the instructions provided with the G26 unit, note especiallythe warnings in the "Return Air Opening Guidelines" section. 3-ff air conditioning coil was removed, re-install coil, reconnect line set and coil drain. See condensing unit installation instructions for re-processing of refrigerant system. Note -Coil drain line must not be connected to heat exchanger condensate drain line. If lines were connected, debris from evaporator could affect heat exchanger operation. 4-Make tow voltage wiring entrance to unit on opposite side from return air connection to prevent blocking filter access. Connect as illustrated in G26 installation instructions. 5 -Connect high voltage wiring as outlined in G26 installation instructions, 6-Connect gas piping as outlined in G26 installation instructions. Consult local codes for flexible connector installation restrictions on G26 furnace. 7 -Connect venting as outlined in G26 installation instructions. Note -Mufflers can not be used in G26 installation. Check existing venting for size (diameter and length). It should meet the specifications as outlined in G26 installation instructions. 8 -Connect heat exchanger condensate drain line as shown in figure 6 and as outlined in G26 unit installation instructions, (A 1/2" PVCto 1/2" CPVC bushing is provided for connecting PVC to existing CPVC condensate line,) 9 -Continue with Unit Start-up Section as outlined in G26 installation instructions. Note -See G26 installation instructions for heat anticipation settings.
