Unless Tiffin has changed things, you should be able to access the furnace from either the outside or inside. If you see a rectangular cover outside your rig where the furnace intake/exhaust is located, you will be able to remove this cover to access the furnace from the outside. Start by removing the stainless steel plate that covers the intake/exhaust.
Both furnaces in our Allegro Bay sit below a drawer and can be accessed from the inside of the motorhome by removing the drawer. If yours is not under a drawer, you can get to the furnace by removing the louvered wooden air return. Gently pry out the wooden buttons that cover the screws that hold the air return in place and then remove the screws.
