Locating the Furnace
1.The furnace should be located in the same room as the central system and as close as possible, but not closer than 9". There should be no wall between the furnace and the warm air outlet duct that is connected directly to the warm air outlet plenum of the central furnace. (See Fig. 2)
2.The unit will require installation with the following clearances:
Unit to sidewall | 12"(305mm) |
Unit to backwall | 30"(760mm) |
Chimney connector pipe to sidewall
.....................................21"(530mm)
Chimney connector pipe to backwall
.....................................18"(460mm)
Hot air ducts to combustibles
.......................................6"(150mm)
(Refer to Fig. 2 & 3)
3.Place the furnace on a noncombus- tible floor.
4.Check figures 2 and 3. Be sure you have the clearances shown from the furnace and the connector pipe to combustible surfaces. If you have a solid brick or stone wall behind your furnace, you can place the furnace as close as you wish to the wall. If the wall is only faced with brick or stone, treat it as a combustible wall.
