WARNING
THESE INSTRUCTIONS ARE INTENDED AS AN AID TO QUALIFIED SERVICE PERSONNEL FOR PROPER
INSTALLATION, ADJUSTMENT AND OPERATION OF THIS KIT. READ THESE INSTRUCTIONS THOROUGHLY

WARNING
THIS KIT IS TO BE USED ONLY FOR TERMINATING CATEGORY IV CONDENSING GAS FURNACES. DO NOT
USE THIS KIT TO TERMINATE ANY OTHER TYPE OF FURNACE. FAILURE TO FOLLOW THIS WARNING
COULD RESULT IN FIRE, PERSONAL INJURY, OR DEATH.
LOCATION
The Concentric Vent Termination Kit can be installed in either
rooftop or sidewall orientation. Before installation procedures
begin, determine the best location for the termination kit.
NOTE: Roof termination is recommended as it is less susceptible to damage, reduces chances of air intake contaminants,
and less visible vent vapors.
ROOF INSTALLATION
STEP 1: Cut a 4" (-E02, -E02A) or 5" (-E02, -E03A) diameter
opening in the roof and install field-supplied weatherseal boot/flashing for the PVC air intake pipe.
STEP 2: Assemble the Vent Pipe Assembly by cleaning and
cementing the rain cap to the smaller diameter PVC
pipe (see Figure 2). Assemble the Intake Pipe
Assembly by cleaning and cementing the “Y” fitting
to the large diameter pipe (see Figure 3).
NOTE: If field disassembly is desired for cleaning, a field-supplied stainless-steel screw may be used to secure the vent cap
to the PVC vent pipe instead of cement.
!
WARNING
WHEN USING ALTERNATE SCREW METHOD, PREDRILL CLEARANCE HOLE IN RAIN CAP AND PILOT
HOLE IN VENT PIPE TO MATCH THE SCREW SIZE
BEING USED. FAILURE TO DO SO MAY CAUSE
CRACKING OF THE PVC COMPONENTS, ALLOWING
COMBUSTION PRODUCTS TO BE RECIRCULATED.
FAILURE TO FOLLOW THIS WARNING COULD
RESULT IN PERSONAL INJURY OR DEATH.

INTAKE PIPE ASSEMBLY
STEP 3: From below, work the intake pipe up through the
seal boot, ensuring that no insulation or debris accumulate in the pipe.
STEP 4: To secure the intake pipe assembly use a field-sup-
plied perforated strap or a suitable type material.
NOTE: Ensure termination height is above the roof surface or
anticipated snow level (1 ft. in USA or 1-1/2 ft. in Canada).
STEP 5: From the roof top, slide the vent pipe assembly
down through the intake pipe. Cement the top of the
intake pipe to the rain hood and the bottom of the
vent pipe to the inner bushing of the the intake pipe
assembly’s “Y” fitting.
STEP 6: Complete vent and intake connections to the fur-
nace.
SIDEWALL INSTALLATION
IMPORTANT: When installing the kit in a sidewall installation,
consider the following when choosing a location:
* Kit is positioned where vent vapors will not damage
plants/shrubs or air conditioning equipment
* Kit is positioned so that wind will not cause com-
bustion products, leaves, snow or other debris from
entering the air intake.
* Kit is positioned where it will not get damaged by
foreign objects (i.e. balls, stones, etc.)
* Kit is positioned where vent vapors will not be
inhaled or cause a nuisance.
STEP 1: Cut a 4
opening in the sidewall and install field-supplied
weather-seal boot/flashing for the PVC vent pipe.
STEP 2: From inside, work the intake pipe through the hole,
ensuring that no insulation or debris accumulate in
the pipe.
STEP 3: To secure the intake pipe assembly use a field-sup-
plied perforated strap or a suitable type material.
NOTE: Ensure termination height is above the anticipated
snow level (1 ft. in USA or 1-1/2 ft. in Canada).
STEP 4: From the outside, slide the vent pipe assembly down
through the intake pipe. Cement the top of the intake
pipe to the rain hood and the bottom of the vent pipe
to the inner bushing of the the intake pipe assembly’s “Y” fitting.
STEP 5: Complete vent and intake connections to the fur-
nace.
