10.Feed thermostat wires from attic to furnace through 1/2" hole in ceiling wall plate.
11.Connect thermostat wires from attic to thermostat wires on furnace. Connect red wires together, then connect white wires together. Use wire nuts to make connections. IMPORTANT: Make sure thermostat wires do not touch combus- tion chamber.
Mounting the Thermostat to Wall
1. | Connect thermostat wires to the two |
| terminal screws on back of thermostat |
| (see Figure 6). Connect red wire to “R” |
| terminal. Connect white wire to “W” |
| terminal. |
2. | Push any excess wire back through hole |
| in wall and plug hole with insulation |
| to prevent drafts. Drafts affect the ther- |
| mostat operation. |
3. | Use thermostat base to mark mounting |
| screw locations. |

CONNECTING TO GAS SUPPLY
WARNING: A qualified ser- vice person must connect fur- nace to gas supply. Follow all local codes.
WARNING: Never connect furnace to private
All piping must comply with local codes and ordinances or with the National Fuel Gas Code (ANS Z223.1 NFPA No. 54), whichever applies.
You can connect furnace to gas supply at front of furnace (inside) or at rear of furnace (outside).
Connecting Furnace to Gas Supply at Front of Furnace
1.Locate gas inlet pipe on lower, right front of furnace (see Figure 8).
2.Connect 3/8" NPT pipe or nipple to gas inlet pipe (see Figure 8). See Provid- ing Gas Piping to Furnace, pages 9 and 10, for correct gas pipe installation.
5. Attach thermostat to wall using screws |
provided (see Figure 7). |
WARNING: Unplug furnace before connecting to gas supply.

CAUTION: Use only new, black iron or steel pipe. Copper tubing may be acceptable in cer- tain areas. Check local codes. Use pipe large enough in diam- eter to allow proper gas volume to furnace. If pipe is too small, undue loss of pressure will oc- cur. Refer to chart on page 9.
