I have a 2000 Tiffin Zephyr diesel pusher. It has a gas furnace which works great. Is there supposed to be a filter somewhere in the coach that requires changing? Thanks, Phil
RV gas furnaces move a lot of air because the heat exchanger is small and gets quite hot. For this reason, I believe, it has been taboo to restrict air flow over the heat exchanger, which a filter would do. Especially since most folks wouldn't keep it clean.
