For those that don’t know – this is the vent for the propane furnace. This is an item on the camper the wasps would love to build nests in. Living in Tenneesee we see wasps building nests everywhere.
We used the heater a few times toward the end of the season last year – but it will not get anymore use until the fall. Its a perfect opportunity for those bugs to build a home and mess up the internal works of the furnace.
We added a mesh grill cover to keep the bugs out.
The cover comes with these little spring retainers that are a huge pain to try and install. There is also no gurantee that those fasteneres will keep the grill in place. I went a different route and used some aluminum wire to fasten the grill to the furnace outlet. Being aluminum the wires will not rust will not hold heat after the furnace has been run.
So far so good, the cover has not moved or loosened up and the furnace works like a charm.
