Important Information for California Residents
California’s Proposition 65, officially known as the Safe Drinking Water and Toxic Enforcement Act of 1986, requires businesses to provide warnings to California consumers when products may expose them to chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
At Eternal Flame Outdoors, we are committed to transparency and customer safety. Some of the products we sell — including fireplaces, heaters, electronics, metals, fuels, and related components — may contain or produce trace amounts of chemicals that appear on California’s Proposition 65 list.
⚠️ Proposition 65 Warning
Certain products sold on this website can expose you to chemicals such as carbon monoxide, lead, silica, nickel, wood dust, or combustion byproducts, which are known to the State of California to cause cancer, birth defects, or other reproductive harm.

What This Means
A Proposition 65 warning does not mean that a product is unsafe or in violation of any product-safety standards. It simply means that California requires a disclosure when exposures to certain listed chemicals could occur — even at very low levels.
Many everyday items, including furniture, appliances, vehicles, construction materials, and cooking equipment, carry similar warnings in California.
Why Some Fireplace & Outdoor Products Carry Warnings
Products such as fireplaces, fire pits, patio heaters, grills, and electrical components may:
- Contain metals or alloys with trace listed chemicals
- Produce combustion byproducts when used
- Include components such as wiring, coatings, glass, or insulation materials
Because these exposures can vary based on installation, use, and environment, manufacturers often require a Proposition 65 warning out of an abundance of caution.
How We Display Warnings
When required, Proposition 65 warnings may appear:
- On individual product pages
- On product packaging or manuals
- Through a clearly marked “CA WARNING” notice with a link to this page
Our Commitment
We work closely with our manufacturers and suppliers to ensure accurate disclosures, regulatory compliance, and high product standards. If you have questions about a specific product, installation, or materials, our team is happy to assist.
