Please read these instructions carefully before installation and retain them for future reference. Proper installation and use will ensure efficient and safe operation of your heating appliance.
2. Safety Information
- Professional Installation Recommended: Installation of this draft regulator should be performed by a qualified professional to ensure compliance with local building codes and safety standards.
- Appliance Compatibility: This draft regulator is designed for use with oil or coal residential or commercial heating appliances. Do not use with gas appliances unless specifically approved by the appliance manufacturer.
- Ventilation: Ensure adequate ventilation in the area where the heating appliance and draft regulator are installed.
- Hot Surfaces: The draft regulator and flue pipe will become hot during operation. Avoid direct contact to prevent burns.
- Regular Inspection: Periodically inspect the draft regulator and flue system for proper function, blockages, or damage.
3. Product Overview
The LLPParts 6-inch Barometric Draft Regulator Damper is designed to maintain a consistent draft in your heating appliance's flue system. It achieves this by counteracting negative forces caused by changes in temperature, barometric pressure, and wind conditions. By stabilizing the draft, the regulator helps optimize combustion efficiency, reduce fuel consumption, and prevent excessive heat loss up the chimney.

4. Setup and Installation
This draft regulator is designed for installation on a 6-inch round flue pipe. It can be used with pipe sizes within 1 inch of the control size (i.e., 5-inch to 7-inch pipes, with appropriate adapters if needed, though 6-inch is optimal).
4.1. Choosing the Installation Location
The draft regulator should be installed in the flue pipe between the heating appliance and the chimney. Consult your appliance manufacturer's instructions and local codes for the exact recommended placement. Typically, it is installed a few feet above the appliance outlet.
4.2. Mounting the Regulator
- Prepare the Pipe: Ensure the section of the flue pipe where the regulator will be installed is clean and free of obstructions.
- Cut Opening: Carefully cut an opening in the flue pipe according to the regulator's dimensions. This typically involves a rectangular or circular opening to accommodate the damper mechanism. Refer to the regulator's specific mounting template if provided.
- Secure Regulator: Insert the regulator into the prepared opening. Secure it firmly to the flue pipe using appropriate fasteners (e.g., sheet metal screws) to ensure a tight, airtight seal. Use high-temperature sealant if necessary to prevent air leaks.
- Initial Adjustment: The regulator is designed for initial settings from 0.02" to 0.08" water column (W.C.) draft. The counterweight on the damper door allows for fine-tuning. Adjust the counterweight until the damper door is balanced and responds smoothly to changes in draft.
5. Operating Instructions
Once installed, the barometric draft regulator operates automatically. Its primary function is to open or close slightly to allow room air into the flue, thereby stabilizing the draft to the desired setting. This prevents excessive draft, which can lead to rapid heat loss and inefficient combustion, and insufficient draft, which can cause incomplete combustion and potential smoke spillage.
5.1. Adjusting the Draft Setting
The optimal draft setting for your appliance is usually specified by the appliance manufacturer. This setting is typically measured in inches of water column (W.C.).
- Measure Draft: Use a draft gauge to measure the actual draft in the flue pipe at the recommended location.
- Adjust Counterweight: To increase the draft (make it stronger), move the counterweight closer to the pivot point of the damper door. To decrease the draft (make it weaker), move the counterweight further away from the pivot point.
- Fine-Tune: Make small adjustments and re-measure the draft until it matches the appliance manufacturer's specifications. The regulator is designed to operate within a range of 0.02" to 0.08" W.C.
A properly adjusted draft regulator will ensure consistent and efficient operation of your heating system.
6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your draft regulator.
- Annual Inspection: At least once a year, or more frequently if the appliance is heavily used, inspect the draft regulator.
- Check for Free Movement: Ensure the damper door pivots freely and is not obstructed by soot, debris, or corrosion. Gently clean any buildup if present.
- Verify Seal: Check that the regulator is still securely attached to the flue pipe and that there are no air leaks around its mounting. Reapply high-temperature sealant if necessary.
- Re-calibrate: If you suspect the draft setting has changed or if the appliance performance degrades, re-measure the draft and adjust the counterweight as described in the Operating Instructions.
7. Troubleshooting
If you experience issues with your heating appliance, the draft regulator may be a contributing factor. Here are some common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Inconsistent or poor appliance performance | Incorrect draft setting; Damper door obstructed or sticking; Flue blockage | Check and adjust draft setting; Clean damper door and pivot points; Inspect flue for blockages. |
| Excessive draft (appliance burns too hot, uses too much fuel) | Draft regulator set too low (not opening enough); Counterweight too close to pivot | Adjust counterweight further from pivot to allow more air in, reducing draft. |
| Insufficient draft (smoke spillage, poor combustion) | Draft regulator set too high (opening too much); Counterweight too far from pivot; Flue blockage or inadequate chimney height | Adjust counterweight closer to pivot to restrict air intake, increasing draft. Check flue for blockages. Consult a professional for chimney issues. |
| Damper door not moving freely | Soot or corrosion buildup on pivot points or door edges | Clean the damper door and pivot mechanism thoroughly. Ensure no debris is impeding movement. |
