2. Determine the best location for the termination kit. See
Figure 3 for vertical termination or Figure 6 and Figure 7
for horizontal termination. Roof termination is preferred
since it is less susceptible to damage, has reduced
intake contaminants and less visible vent vapors. For
side termination, consideration should be given to:
a. Possible damage from the vapors to plants/shurbs,
other equipment and building materials
b. Possible damage to the terminal from foreign ob-
jects
c. Wind effects that may cause recirculation of flue
products, debris or light snow
d. Visible vent vapors.
Vent
Maintain 12" (18" for Canada)
minimum clearance above highest
anticipated snow level. Maximum of
24" above roof.

WARNING
DO NOT OPERATE THE FURNACE WITH THE RAIN CAP REMOVED AS
RECIRUCLATION OF THE FLUE GASES MAY OCCUR.
WATER MAY ALSO
COLLECT INSIDE THE LARGER COMBUSTIN AIR PIPE AND FLOW TO THE
BURNER ENCLOSURE.
F
AILURE TO FOLLOW THIS WARNING CAN RESULT IN
PROPERTY DAMAGE, EQUIPMENT DAMAGE, PERSONAL INJURY OR DEATH.
6. Install the Y concentric fitting and the pipe assembly
through the structure’s opening. For vertical termina-
tion, install the parts through the field supplied roof boot/
flashing. NOTE: Do not allow insulation or other mate-
rials to accumulate inside the pipe assembly when in-
stalling through the structure’s opening.
7. Secure the assembly to the structure as shown in Fig-
ure 3 or Figure 7 using field supplied metal strapping or
equivalent material.
NOTE:
• Ensure that the strap is installed to prevent movement
of termination kit in side wall.
• Ensure the termination height is above the roof surface
or anticipated snow level as shown in Figure 3 for vertical
termination.
• Ensure the termination location clearance dimensions
are as shown in Figure 6 and Figure 7 for horizontal
terminiation.
