CLEARANCES
1.In selecting a location for installation, it is necessary to provide adequate accessibility clearances for servicing and proper installation.
2.Clearances to combustible surfaces are 4" (102mm) from sides, 12" (305mm) to top, 1 1/2" (38mm) from floor.
NOTE: Minimum distance of 1 1/2" (38mm) must also be maintained from top surface of carpeting, tile, etc.
VENTILATION AND COMBUSTION AIR
Wall furnaces shall be installed in a location in which the facilities for ventilation permit satisfactory combustion of gas and proper venting under normal conditions. In buildings of conventional frame, brick, or stone construction without tight storm windows and doors, infiltration is normally adequate to provide air for combustion and draft hood dilution.
Where appliances are installed in confined and unconfined spaces withinabuilding,thebuildingbeingofunusuallytightconstruction, air for combustion and ventilation must be obtained directly from outdoors or from such spaces that freely communicate with the outdoors. Under these conditions, the confined and unconfined spaces shall be provided with two permanent openings, one near the top of the enclosure and one near the bottom; each opening shall have a free area of not less than one square inch (6.45cm2) per 2,000 BTU (.6KW/H) per hour of total input.
LOCATION - ALL MODELS
Select a location near the center of the space to be heated. Overflow heat will circulate through doorways into adjacent rooms.
For large homes or
Do not install in a closet, alcove or small hallway where the furnace could be isolated by closing doors to the heated space.
When location is selected, check the walls, attic and roof to make sure there are no obstructions such as pipes, electric wiring, etc., which would interfere with the installation of the furnace or vent pipe.
NOTE: If Rear Register Kit is to be used, see Rear Register Kit instructions for location of hole in rear wall. Register outlet must be cut in wall before furnace is installed.
NOTE: If Optional Blower is to be used, hard wiring must be completed for the optional blower prior to installation of header plate.
ROUGH-IN INSTRUCTIONS
Provide an opening in the wall 14 1/2" (368mm) wide and 66 1/8" (168cm) high measured from top of floor plate (See Figure 2 and Figure 3). Wall depth is to be 2" x 4" framing with 1/4" (6.5mm) to 5/8" (16mm) sheeting. Attach baseplate (not supplied with furnace) to header plate with sheet metal screws at each end. Attach 4" (102mm) oval, double wall vent pipe to baseplate.Attach enough vent pipe so that when installed in wall opening the vent pipe will extend above the ceiling plate by at least 6" (152mm).
Install ceiling spacers according to manufacturer's instructions. Insert header plate with attached 4" oval, double wall vent pipe into wall opening. Position header plate at height shown in Figure
2.Locate rear edge of nailing flange at the back of the 2" x 4" stud which will center the vent collar in the wall. Locate the angled edge of header plate flush with the top of the wall opening. Nail header plate to the wall studs.
