, the venting system may be
too large to properly vent the remaining attached appliances.

90 degrees for Category I venting. For horizontal installations, a
four inch single wall pipe can be used to extend the induced draft
blower outlet 1/2” beyond the furnace cabinet. THIS PR

THIS FURNACE IS NOT DESIGN CERTIFIED TO BE HORIZONTALLY
VENTED.
To rotate the induced draft blower clockwise, you will need to pur-
chase one (0270F01119) chimney transition bottom kit.
1. Disconnect electrical power from the furnace.
2. Disconnect the induced draft blower power leads, flue pipe,
and pressure switch tubing.
3. Remove the round cutout from the right side of the wrapper.
4. Remove and save the four screws that fasten the induced
draft blower to the flue collector box.
5. Remove and save the three screws that hold the chimney
assembly to the induced draft blower.
6. Remove and save the four screws that fasten the chimney
top to the chimney bottom.
7. Remove the chimney transition bottom from the transition
bottom kit.
8. Install the chimney top with the four screws retained from
step 6 onto the new chimney transition bottom from the
transition bottom kit.
9. Install chimney assembly with the three screws retained
from step 5 onto the induced draft blower.
10. Reinstall the induced draft blower rotating it 90 degrees
clockwise from the original upflow configuration using the
four screws retained in step 3. Ensure the gasket located
between the induced draft blower and the collector box is
rotated accordingly.
11. Reconnect the induced draft blower power leads. NOTE: If
the wires are not long enough, pull extra wire from the wire
bundle in the blower compartment.
12. Reconnect the flue pipe, and the pressure switch tubing.
Ensure that all wires and the pressure switch tubing is at
least one inch from the flue pipe, or any other hot surface.
13. Restore power to furnace.

An exterior masonry chimney is defined as a “Masonry” chimney
exposed to the outdoors on one or more sides below the roof line.”
The ability to use a clay lined masonry chimney depends on a pa-
rameter not associated with interior chimneys. This variable is the
geographic location of the installation. Researchers have discov-
ered that the winter design temperatures have a direct impact on
the suitability of this type of venting. In most situations, the existing
masonry chimneys will require a properly sized metallic liner.
