GENERAL INFORMATION (cont.)
WARNING
THIS FURNACE IS NOT APPROVED OR RECOM-
MENDED FOR INSTALLATION ON ITS BACK, WITH
ACCESS DOORS FACING UPWARDS.
SITE SELECTION
1. Select a site in the building near the center of the pro-
posed, or existing, duct system.
2. Give consideration to the vent system piping when se-
lecting the furnace location. Be sure the venting system
can get from the furnace to the termination with mini-
mal length and elbows.
3. Locate the furnace near the existing gas piping. Or, if
running a new gas line, locate the furnace to minimize
the length and elbows in the gas piping. See Figure 5.
4. Locate the furnace to maintain proper clearance to
combustibles as shown in following Figure 6.
WARNING
DO NOT LIFT THE UNIT BY THE HEAT EXCHANGER
TUBES. DOING SO CAN DAMAGE THE HEAT EX-
CHANGER ASSEMBLY.
CLEARANCE – ACCESSIBILITY
The design of forced air furnaces with input ratings as
listed in the tables under Figure 6 are certified by CSA-In-
ternational for the clearances to combustible materials
shown in inches.
See name/rating plate and clearance label for specific
model number and clearance information.
Service clearance of at least 24 inches (61 cm) is recom-
mended in front of all furnaces.
NOTE: Use recommended 24" (61 cm) clearance if accessi-
bility clearances are greater than fire protection clearances.
For downflow non-zero clearance furnace installations, the
minimum clearance required on the right side of the fur-
nace is shown in Figure 4. If this clearance cannot be
maintained, a downflow zero-clearance kit; RXGY-ZK will
need to be installed.

STALLED DIRECTLY ON CARPETING, TILE OR
OTHER COMBUSTIBLE MATERIAL OTHER THAN
