Can a plastic water heater pan be installed above a finished ceiling?

You should always check with your local building and fire officials before installing a plastic pan above a finished ceiling. If the return air to the furnace is not isolated through air tight duct work or the open ceiling is used for the return air, the plastic pan should never be used. If the plastic pan is used in these applications and exposed to flames, the toxic smoke can be drawn back to the furnace and distributed throughout the building.
