Suitable For Vermiculite InsulationYes (Note: Inspection hole cover plates must remain in place if vermiculite is installed)
For a proper installation, begin by measuring and marking the chimney base to ensure the register plate is correctly positioned. The four supporting brackets included with the plate should be cut to the required length using standard metal snips, then fixed firmly into the brickwork with standard screws. Once the register plate is cut to size, place it over the base, aligning the access holes with the intended flue pipes. Secure the plate using fire cement or high-temperature sealant to ensure no gaps remain, which could compromise heat efficiency or allow debris to enter. It is vital to retain the inspection hole cover plates if vermiculite insulation is used. Regular maintenance, including an annual sweep and debris clearance, will ensure continued optimum performance.
