Carefully read the manufacturer's instructions before operating the fireplace for the first time.
Keep children and combustibles away from hot surfaces during operation.
Keep fans and air-circulating passageways clean and clear.
Install a carbon-monoxide detector near your fireplace.
Be alert for unusual odors or flames, which can be indications that your fireplace isn't working properly.
Wood fireplaces:
Never leave a fire unattended.
Have the chimney inspected annually and cleaned as necessary by a professional chimney sweep.
Keep a fire extinguisher on hand.
Always use the fire screen when in use.
Clean out ashes from the previous fire.
Never burn garbage, newspapers, charcoal or plastic.
Make sure the fire is completely out before going to bed or leaving the house.
