- Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and sturdy footwear.
- Ensure the work area is stable, clear of obstructions, and well-lit.

3. Package Contents
Upon opening the package, verify that all components are present and undamaged.
- Gelco 20-56 Inch Crown-Form sections (1 pair, consisting of multiple interlocking pieces).
Note: To create a complete set for larger crowns, two pairs of forms may be required. This package contains one pair.
4. Setup
Proper setup of the Crown-Form is crucial for achieving a well-formed chimney crown.
- Prepare the Chimney Top: Ensure the top of the chimney is clean, level, and free from debris. Any loose mortar or bricks should be repaired before proceeding.
- Assemble the Form Sections: The Crown-Form consists of multiple straight-sided steel sections. Select the appropriate sections based on the desired chimney crown dimensions. Slide the sections together, interlocking them securely.
- Adjust to Chimney Dimensions: Place the assembled form onto the chimney top. Adjust the form to match the outer dimensions of the chimney, ensuring a snug fit. The forms are designed to create a minimum 1.5-inch overhang or drip edge around the chimney flue.
- Secure the Form: Once adjusted, ensure the form is stable and level. If necessary, use clamps or weights to hold the form firmly in place during the pouring process.
5. Operating Instructions
Follow these steps for pouring and curing your chimney crown using the Gelco Crown-Form.
- Prepare Crown Mixture: Mix your chosen chimney crown material (e.g., concrete, mortar mix) according to the manufacturer's instructions. The mixture should be of a workable consistency, suitable for pouring.
- Pour the Mixture: Carefully pour the crown mixture into the assembled Gelco Crown-Form. Fill the form evenly, ensuring there are no air pockets. Use a trowel or similar tool to spread and level the mixture.
- Finish the Surface: Once the form is filled, use a float or trowel to create a smooth, sloped surface that directs water away from the flue and chimney walls. Ensure the 1.5-inch drip edge is maintained.
- Allow to Cure: Allow the crown mixture to cure according to the material manufacturer's recommendations. Curing time can vary based on temperature, humidity, and the specific mix used. Protect the crown from rain or extreme temperatures during the initial curing phase.
- Remove the Form: Once the crown mixture has sufficiently cured and hardened (typically after 24-48 hours, but refer to your mix instructions), carefully remove the Gelco Crown-Form. Gently loosen any securing clamps and lift the form sections away from the newly formed crown.
6. Maintenance
Proper maintenance will extend the life of your Gelco Crown-Form.
- Cleaning: After each use, thoroughly clean any residual concrete or mortar from the form sections. Use a stiff brush and water. For stubborn residue, a wire brush or scraper may be used carefully to avoid damaging the steel.
- Drying: Ensure all form sections are completely dry before storage to prevent rust.
- Storage: Store the forms in a dry, protected area. Keeping them organized will make future assembly easier.
- Inspection: Periodically inspect the forms for any signs of damage, bending, or excessive wear. Damaged forms may affect the quality of the chimney crown.
7. Troubleshooting
This section addresses common issues that may arise during the use of the Gelco Crown-Form.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Crown Surface | Form not level; inconsistent pouring; improper finishing. | Ensure form is perfectly level before pouring. Pour mixture evenly and finish with a float or trowel to create a smooth, consistent slope. |
| Crown Mixture Leaks from Form | Form sections not securely interlocked; gaps between form and chimney. | Verify all form sections are tightly connected. Seal any small gaps between the form and the chimney with a temporary barrier if necessary. |
| Difficulty Removing Form | Crown not fully cured; form stuck due to excess mixture. | Allow adequate curing time. Gently tap the form edges to loosen. Ensure no excess mixture has hardened around the form's exterior. |
| Crown Does Not Have 1.5-inch Overhang | Form not adjusted correctly to chimney dimensions. | Before pouring, double-check the form's placement and adjustment to ensure the required overhang is achieved. |
