90% Furnace Concentric Vent Kit Used with ALL 90% Thru 95% Efficent Furnaces ALL Brands (Horizontal or Vertical Installations)

HORIZONTAL INSTALLATION:

SIDE WALL TERMINATION

1. Determine best location for termination kit.
a. Termination kit positioned where the vent vapors will not damage plants, shrubs, air conditioning equipment, or the existing structure.
b. Termination kit positioned so it will not be affected by wind, that may allow recirculation of combustion products, air borne leaves, light snow or fertilizer.
c. Termination kit positioned where it will not get damaged or be subjected to foreign objects: stones, balls, etc.
d. Termination kit positioned where the vent noise will not be objectionable to abutters.
2. Cut a hole (4
• diameter for 2
• concentric vent kit or 5
• diameter for 3
• concentric vent kit).
3. Partially assemble concentric vent termination kit.
a. Cement the Y concentric fitting to larger diameter kit pipe (See Figure 1).
b. Cement the rain cap to the smaller diameter kit pipe (See Figure 1).
4. Install Y concentric fitting and pipe assembly through the structure
•s hole.
Note: Do not allow insulation or other materials to accumulate inside pipe assembly when installing through hole.
5. Install rain cap and small diameter pipe assembly in Y concentric fitting and large pipe assembly. Ensure small diameter pipe is bottomed and cemented in Y concentric fitting.
6. Secure assembly to structure as shown in Figure 6, using field supplied metal strapping or equivalent support material.
Note: Ensure termination location clearance dimensions are in instructions.
Note: If assembly needs to be extended to allow side wall thickness requirement, the two pipes supplied in the kit may be replaced by using the same diameter, Field supplied SDR-26 (D2241) pipe. Do not extend dimension D to more than 60
• (see Figure 2). DO NOT USE COUPLINGS TO EXTEND PIPE.
7. Cement air inlet vent pipe and exhaust vent pipe to concentric vent termination assembly. See Figure 6 for proper pipe attachment.
8. Operate boiler through a heating cycle to ensure air inlet vent pipe and exhaust vent pipes are properly connected to concentric vent termination connections.
9. Allow 8
• center-to-center distance between concentric vent terminations on multiple boiler installations.

VERTICAL INSTALLATIONS

ROOF TERMINATION
1. Determine the best location for the termination kit.
Note: A roof termination is less susceptible to damage. It has reduced chances to intake contaminants and has less visible vent vapors.
2. Cut a hole (4
• diameter for 2
• concentric vent) or 5
• diameter for 3
• concentric vent kit).
3. Partially assemble concentric vent termination kit.
a. Cement Y concentric fitting to larger diameter kit pipe
b. Cement rain cap to smaller diameter kit pipe
4. Install Y concentric fitting and pipe assembly through the structure
•s hole and field supplied roof boot/flashing.
Note: Do not allow insulation or other material to accumulate inside pipe assembly when installing through hole.
5. Secure assembly to roof structure as shown in Figure 4. using field supplied metal strapping or equivalent support 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) as shown in Figure 3.
Note: If assembly is too short to meet height requirements, the two pipes supplied in the kit may be replaced by using same diameter, field supplied SDR-26 PVC (D2241) pipe. Do not extend dimension D more than 60
•. Do not use couplings to extend pipe.
Note: When shortening the length of the concentric vent, the inner pipe is longer than the outer pipe. Make sure you cut the same amount from each pipe. Do not make them equal in length.
