1. Introduction

This manual provides instructions for the installation, operation, and maintenance of the Selkirk 284875 Type L Pellet Kit. This kit is designed as a thru-the-wall vent system specifically for pellet stove applications, intended for horizontal installations only.

Important Safety Information: Always ensure that the appliance's flue gases do not exceed 570°F (299°C). Installation must comply with all local building codes and regulations. It is recommended that installation be performed by a qualified professional.

2. Package Contents

The Selkirk 284875 Type L Pellet Kit includes the following components:

• One 4-inch horizontal cap
• One 4-inch 90-degree elbow
• One 4-inch wall bracket
• Five 4-inch x 1-foot pipe lengths
• One 4-inch tee with cleanout
• One 4-inch wall thimble
• One 4-inch tee support
• One 3-inch to 4-inch pellet increaser
• One 3-inch pipe connector

3. Setup and Installation

This pellet kit is designed exclusively for horizontal thru-the-wall installations. Do not attempt vertical or other configurations.

1. Planning: Determine the optimal location for the pellet stove and the vent exit point through the wall, ensuring compliance with all clearance requirements from combustible materials as specified by the stove manufacturer and local codes.
2. Wall Thimble Installation: Install the 4-inch wall thimble through the exterior wall. This component provides a safe passage for the vent pipe.
3. Connecting Components: Begin assembling the pipe sections, 90-degree elbow, and tee with cleanout. Ensure each connection is secure. Selkirk recommends using high-temperature silicone sealant to join the pieces for an airtight seal. Alternatively, high-quality foil tape designed for high-temperature applications can be used.
4. Pipe Lengths: Utilize the five 4-inch x 1-foot pipe lengths to achieve the necessary horizontal run.
5. Increaser and Connector: Connect the 3-inch to 4-inch pellet increaser to the pellet stove's flue outlet, then attach the 3-inch pipe connector to complete the initial connection to the stove.
6. Support: Install the 4-inch wall bracket and 4-inch tee support to securely hold the vent system in place, preventing strain on the stove and ensuring stability.
7. Horizontal Cap: Install the 4-inch horizontal cap at the exterior termination point of the vent system.
8. Final Inspection: After assembly, visually inspect all connections for tightness and proper sealing. Verify that the entire system is adequately supported and free from obstructions.

For detailed diagrams and specific measurements, refer to the installation guide provided with your pellet stove or consult a certified HVAC professional.

4. Operating Instructions

The Selkirk Type L Pellet Kit functions as a passive vent system for your pellet stove. Proper operation relies on correct installation and maintenance.

• Flue Gas Temperature: Ensure that the pellet stove's flue gas temperature does not exceed 570°F (299°C). Exceeding this temperature can compromise the integrity of the vent system.
• Airflow: The vent system is designed to provide adequate exhaust for your pellet stove. Any blockages or restrictions will impair stove performance and could pose a safety hazard.
• Monitoring: Regularly observe the stove's performance and the vent system for any signs of improper drafting, smoke leakage, or unusual odors.

5. Maintenance

Regular maintenance is crucial for the safe and efficient operation of your pellet stove vent system.

• Routine Inspection: Periodically inspect the entire vent system, including all pipe sections, connections, the wall thimble, and the horizontal cap, for any signs of damage, corrosion, creosote buildup, or blockages.
• Cleaning: The 4-inch tee with cleanout is designed to facilitate easy access for cleaning. Regularly remove the cleanout cap and clear any accumulated ash or creosote from the vent system. The frequency of cleaning depends on stove usage and fuel type.
• Seals: Check all sealed joints for integrity. Reapply high-temperature sealant or tape if any signs of leakage or degradation are observed.
• Obstructions: Ensure the exterior horizontal cap is free from bird nests, debris, or other obstructions that could impede exhaust flow.

6. Troubleshooting

If you encounter issues with your pellet stove's venting, consider the following:

• Poor Draft/Smoke Back-up:
  • Check for blockages in the vent pipe or horizontal cap.
  • Ensure all connections are sealed properly.
  • Verify that the flue gas temperature is within the acceptable range (below 570°F).
• Smoke or Odor Leakage:
  • Inspect all joints and seals for damage or improper installation.
  • Ensure the wall thimble is correctly installed and sealed.
• Excessive Creosote Buildup:
  • Increase cleaning frequency.
  • Ensure the pellet stove is operating efficiently and burning fuel completely.

For persistent issues or concerns regarding safety, contact a qualified heating technician.
