Furnace Installation
SF2600.
This figure represents the model SF2600 furnace. It’s intention is to represent the approximate location of the various controls. This drawing may also be used as a reference for wiring and control spacing. Please note that this drawing is for reference only. Specific installations will vary.
Mounting The Blower And Filter Box
Position the filter box between the brackets on the rear of the furnace, with the bottom of the box resting on the flange at the bottom of the furnace. Insert the mounting clips into the bracket slots to secure the filter box. (see Figure 2) Next, install the blower brackets onto the blower being sure to install the rubber feet into the brackets. NOTE: On the SF3500, install the blower mount and blower before the filter box. All hardware, brackets, etc. for the blower, will be found in the carton with the blower. Next, position the blower in the filter box, centered behind the inlet hole and allow approximately 1/8 in. space between the rear of the furnace and the blower outlet. Now, install the filter rail onto the filter box. NOTE: The filter rail is best installed on the side toward the shaker handle, so that any pipes from the hot water coil do not interfere with filter installation or removal.
NOTE: Before proceeding with the installation of the access door, it is suggested that the wiring be completed. The access door is installed by slipping the flange on the bottom of the access door over the bottom rail of the filter box opening, then push the top of the door against the top of the filter box opening and secure with a sheet metal screw.
