RONT OVER RESSURE
When an upflow model is installed horizontally with left side down or a counterflow model is installed horizontally with right
side down, the front cover pressure switch tube must be re-located to the lower port of the collector box cover.
1. Remove tube from front cover pressure switch and collector box cover.
2. Remove rubber plug from bottom collector box port and install on top collector box port.
3. Locate 24" x 1/4" tube in parts bag.
4. Install one end on front cover pressure switch.
5. Route tube to lower port on collector box cover and cut off excess tubing.

RAIN RAP AND INES
In horizontal applications the condensate drain trap is secured to the furnace side panel, suspending it below the furnace. A minimum
clearance of 5 1/2 inches below the furnace must be provided for the drain trap. Additionally, the appropriate downward piping slope
must be maintained from the drain trap to the drain location. Refer to Condensate Drain Trap and Lines for further details. If the drain
trap and drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to prevent condensate
from freezing.
L
EVELING
Leveling ensures proper condensate drainage from the heat exchanger. For proper flue pipe drainage, the furnace must be level
lengthwise from end to end. The furnace should have a slight tilt from back to front with the access doors downhill from the
back panel approximately 1/2 to 3/4 inches. The slight tilt allows the heat exchanger condensate, generated in the recuperator
coil, to flow forward to the recuperator coil front cover.

LTERNATE LECTRICAL AND
This furnace has provisions allowing for electrical and gas line connections through either side panel. In horizontal applications the
connections can be made either through the "top" or "bottom" of the furnace.

RAIN AN
A drain pan must be provided if the furnace is installed above a conditioned area. The drain pan must cover the entire area under the
furnace (and air conditioning coil if applicable).

REEZE ROTECTION
Refer to Horizontal Applications and Conditions - Drain Trap and Lines.

ROPANE AS IGH L TITUDE
This furnace is shipped from the factory configured for natural gas
up to 10,000 ft. altitude. Propane conversions require the proper
LP kit to compensate for the energy content difference be-
tween natural and propane gas.
For furnaces being converted to LP gas, it is strongly recom-
mended that a LPLP03 kit also be installed. The use of this kit
will prevent the furnace from firing when the LP gas supply
pressure is too low to support proper combustion.
The indicated kit must be used to ensure safe and proper furnace
operation. All conversions must be performed by a qualified in-
staller, or service agency.
