| 1. | Remove the small lower galley door (and hinges) covering the 8 3/8" wide by 11 1/4" high routed furnace opening in the lower galley front. Reinsert the hinge screws in the exposed holes and tighten until flush with the lower galley front. | ||||||||||||||||||||||||||||||||||||||
| 2. | Remove the wall paneling knock-out centered directly behind the furnace opening on the lower galley front. | ||||||||||||||||||||||||||||||||||||||
| 3. | Cut the vent opening in the body panel according to the dimensions in figure 1. | ||||||||||||||||||||||||||||||||||||||
| 4. | Install the 3 ½" wooden heater support with two self-tapping screws. | ||||||||||||||||||||||||||||||||||||||
| 5. | Drill a 1" hole for furnace gas line by using the white plastic pin as a locator mark. | ||||||||||||||||||||||||||||||||||||||
| 6. | Connect the plugged end of the power supply wires (black, orange, white) found in the lower galley compartment to the heater wire harness supplied in kit. Pull the non-plugged end of the wire harness out through the lower galley front opening. | ||||||||||||||||||||||||||||||||||||||
| NOTE: Once the two wire harnesses are connected, check to ensure proper color coding, black to black, orange to orange, etc. | |||||||||||||||||||||||||||||||||||||||
| 7. | Clamp the furnace power supply wires by the right side of the heater box with two plastic clamps and two self-tapping screws provided. | ||||||||||||||||||||||||||||||||||||||
| 8. | Slide furnace into opening except for approximately 6" for wire connections. | ||||||||||||||||||||||||||||||||||||||
| 9. | Connect wires found in compartment to furnace
with the three quick connectors (1216-208) as follows: a. Orange - white wire on furnace marked "thermostat" b. White (-12 VDC) - black wire on furnace c. Black (+12 VDC) - red wire on furnace |
||||||||||||||||||||||||||||||||||||||
| 10. | Slide excess wires back into furnace compartment. | ||||||||||||||||||||||||||||||||||||||
| 11. | Slide furnace into compartment until flange of furnace contacts furnace galley front. Make certain furnace aligns with vent opening. | ||||||||||||||||||||||||||||||||||||||
| 12. | Secure furnace to the wooden galley front with two screws, one on each side of the furnace. | ||||||||||||||||||||||||||||||||||||||
| 13. |
Apply putty tape to perimeter of vent sleeve flange that contacts the body panel once installed and slide into rear of furnace casing. Apply putty tape to top and sides of rear exterior vent assembly that seals against the vent sleeve. Slide exhaust tube into rear of furnace and fasten vent sleeve and vent to panel with two self-tapping screws provided. See figure 2. |
||||||||||||||||||||||||||||||||||||||
| IMPORTANT: A minimum overlay of ½" must be maintained between vent sleeve and furnace casing for proper air exchange. | |||||||||||||||||||||||||||||||||||||||
| 14. | Use the back of the thermostat plastic base as a template and mark the seat panel as shown in figure 3. Cut out this opening with a jigsaw or other suitable cutting tool. | ||||||||||||||||||||||||||||||||||||||
| NOTE: The appropriate seat bench will have the black and orange thermostat wires rolled up and marked inside the compartment. | |||||||||||||||||||||||||||||||||||||||
| 15. | Locate the color-coded thermostat wire harness. The wire harness will consist of one orange and one black with flanged spade terminals. Place the plastic grommet provided through the center hole in the metal U-shaped thermostat bracket. Route the spade terminals through the metal U-shaped bracket and then through the hole cut in step 14. Continue to route the wires through the center hole in the thermostat plastic base and attach the wires to the thermostat: black wire to the fused side of the thermostat (thin copper wire); orange wire to the heat anticipator side of the thermostat. Attach the plastic base to the U-bracket and bench panel with the two short rivets provided. Attach the thermostat to the plastic base with the two long rivets and two flat washers provided. See figure 3. Connect the male plastic plug end of the thermostat wire harness to the female plastic plug end on the remaining thermostat compartment wires. | ||||||||||||||||||||||||||||||||||||||
| NOTE: Once the two wire harnesses are connected, check to ensure proper color coding, black to black, orange to orange, etc. | |||||||||||||||||||||||||||||||||||||||
| 16. |
Secure thermostat wires to floor with the two remaining plastic clamps and two self-tapping screws. |
||||||||||||||||||||||||||||||||||||||
| 17. | Cut existing gas line on trailer directly below heater gas line hole. Put on two flare nuts and flare gas line. Install 3/8" tee. Fasten gas line to trailer frame using two black clamps and two self-tapping screws. Attach gas line to heater, route through floor, and attach to 3/8" tee. | ||||||||||||||||||||||||||||||||||||||
| 18. | Check all gas connections for leaks. Apply pressure to gas supply line and test all connections for possible leaks using a soap solution. | ||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||
| 19. | Install inside furnace cover. | ||||||||||||||||||||||||||||||||||||||
| 20. | Refer to furnace operating manual for lighting instructions. | ||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||
| NOTE: After furnace installation is complete, test fire the furnace and allow it to operate for one complete cycle. This operation will insure the furnace is functioning properly and will burn off any unwanted residue inside the furnace. | |||||||||||||||||||||||||||||||||||||||
