## Questions & Answers

**Q: How do I determine the correct size for my fireplace flue?**
A: Measure your flue's interior and choose a Flueblocker the same size or slightly larger. The wool pad pressure-fits and can be trimmed with scissors. Use the sizing guide to match your flue shape—round, square, or rectangular.

**Q: How difficult is installation? Do I need any special tools or supports?**
A: Choose an install spot you can reach by hand. Measure with a tape or ruler. A narrow area above the firebox is ideal. For higher spots, use 6” handle extenders to place the wool pad securely.

**Q: Will the product completely block cold drafts, odors, and heat loss?**
A: When fitted correctly, the FlueBlocker stops heating/cooling loss, drafts and odors from a dormant chimney. To eliminate odor, make sure you vacuum out all the ash from the firebox and seal any ash chute or outside intake attached to the firebox.

**Q: Which is right for my situation – a FlueBlocker or a Chimney Balloon?**
A: The Flueblocker is a durable, reusable chimney plug that handles moisture and is ideal for long-term use. The Chimney Balloon offers a tight seal and a breakaway feature for safety if a fire is lit accidentally.

**Q: How durable is the material? Is it worth the price?**
A: Chimney is harsh, moist, acidic environments. The Flueblocker uses coarse ionized Herdwick wool and durable resin hardware to seal air, wick moisture and resist odors. Chimney Balloons use a heat-reactive laminate to withstand chimney air conditions.
