Field conversion: horizontal right with vertical vent

What is going on

Field conversion to horizontal right airflow with a vertical vent. Steps 1 and 2 are done with the furnace in as-shipped condition. Parts come from the parts bag and conversion kit RXGY-CK.

Check in this order

1. Gather parts from the parts bag and kit RXGY-CK: 1/2 inch drain hose E, 1/2 inch drain hose F, condensate trap gasket, 1/4 inch black vent tube, three #8 x 1/2 inch screws, 2 inch pipe grommet, 2-5/8 inch flush-mount plug, intake coupling and nut, and air diffuser.
2. Gather tools electric drill with 1/8 inch bit, pliers, flat-head screwdriver, 5/16 and 1/4 inch hex drivers, and a tubing cutter.
3. Step 1a Remove the flue transition, transition coupling and elbow. Removing the inducer coupling with the elbow makes this easier.
4. Step 1b Remove the condensate trap and hoses. To remove the trap, take out the two screws and pull it straight out.
5. Step 2a Relocate the 1/2 inch yellow vinyl cap on the inducer coupling.
6. Step 2b Remove the 3-3/8 inch flush-mount plug from the jacket side and discard it.
7. Step 2c Keep the IDB coupling and the transition coupling. If the IDB coupling is removed, it must go back in the correct direction (see the related tip).
8. Step 2d Install the 2-5/8 inch flush-mount plug in the top plate.
9. Step 3a Relocate the 0.403 inch drain plug in the collector box.
10. Step 3b Relocate the 1/4 inch yellow vinyl cap on the collector box vent tap.
11. Step 4a Remove the rectangle flush-mount plug from the jacket side and discard it.
12. Step 4b Pre-drill three 1/8 inch holes as shown for the condensate trap.
13. Step 4c Install the 2 inch pipe grommet in the jacket.
14. Step 4d Slide the air diffuser into the intake coupling, then install the coupling into the jacket. Seat the air diffuser fully.
15. Step 5a Remove the metal bracket and the 0.403 inch drain plug, and discard them.
16. Step 5b Remove hose A and discard it.
17. Step 5c Install the 0.559 inch condensate drain plug and condensate trap gasket as shown.
18. Step 5d Install the condensate trap in the jacket with three screws. The trap may be installed later, after the unit is rotated, to avoid damage.
19. Run the review checklist before startup (see the related tip).
