You may want to purchase one if the current tray in your home needs replacing or it doesn't fit well. You should also consider getting an ash pan for high-efficiency fireplaces that don’t require open doors. It can be difficult for ashes and other debris to make their way out of these types of fireplaces without proper ventilation, which means they could end up inside your house instead! An easy solution is simply getting an ash pan fitted in place before lighting the flame in your new appliance – this will keep excess material contained during usage.
