Installation of Three-prong (Grounding) Plug Assembly
1.Disconnect nylon cap on 3' plug assembly from nylon plug on wiring harness. Remove 3' plug assembly from control compart- ment (bottom) of the furnace.
2.Remove 7/8" knockout from appropriate side panel.
3.Insert nylon cap on 3' plug assembly into the 7/8" hole in the side panel.
4.Connect nylon cap on 3' plug assembly to nylon plug on the wiring harness.
5.Place 7/8" strain relief bushing around the cord of the 3' plug assembly. Insert 7/8" strain relief bushing into the 7/8" hole in the side panel.
Attention! The 7/8" strain relief bushing is located within the same envelope as the Installation Instructions and Owner's Manual.
Attaching Furnace to Wall
Place collar on four inch flue tube against combustion chamber back. Align clearance holes on collar with screw holes in combustion chamber back. Attach four inch flue tube to combustion chamber back with four (4) 10 x 1/2" screws.
Place collar on six inch air tube against air drop. Align clearance holes on collar with screw holes in air drop. Attach six inch air tube to air drop with eight (8) 10 x 1/2" screws.
Refer to Figure 5 for the location of the 7 1/2" diameter wall open- ing for the furnace. After the wall opening has been located and cut, position flue outlet on furnace in center of wall opening. Insert tubes through wall opening. When attaching furnace to the wall remove that portion of baseboard and molding on the wall which is behind the furnace. Attach furnace to wall, at the outer casing top, with two (2) plastic expansion anchors provided and to floor, at the outer casing bottom, with two (2) 10 x 1 1/2" screws provided.
Using Plastic Expansion Anchors
1.After locating mounting holes, drill two (2) 5/16" diameter holes into the wall.
2.Insert two (2) plastic expansion anchors provided into the holes.
3.Tighten two (2) 10 x 1" screws provided into the plastic expansion anchors. (See Figure 9)

Installing Vent Assembly
Attention: DO NOT attempt to cut vent tubes. When you order appropriate vent kit for measured wall depth the vent tubes will fit together.
1.Place provided caulking beneath the collar of the outside mounting plate. Use additional caulking to correct uneven wall surface, such as clapboard.
2.Insert six inch air tube on outside mounting plate INTO six inch air tube attached to air drop. Place four inch flue tube on vent cap OVER four inch flue tube attached to combustion chamber. Position the outside mounting plate so that six inch air tube has a slight downward slope to the outside. The downward slope is necessary to prevent the entry of rainwater. Attach outside mounting plate to exterior wall with four (4) 10 x 1 1/2" screws.
3.Installation is completed.
