Do these water-vapor fireplaces come with logs?

There are special logs designed specifically for the Dimplex Opti-Myst cassettes that you can purchase as an additional accessory. For the aFirewater models, however, there are no special logs that are made for this brand (like there are for Opti-Myst for example) so, you might have to improvise with other loose decorative logs that are available for electric and ethanol fireplaces.
