Odor when using tank heaters

Make sure the vent pipes are sealed to the camper roof INSIDE or under the pipe vent covers. Most don't do that.... It not to stop leaks it's to stop the smell from reentering the cabin. They sometimes drill too big a holes and don't seal the pipe to roof underneath the rain cover. Then sewer gas go back in cabin.

This most likely culprit of all.

Is there any liquid in all 3 tanks? I’m thinking you might not want to heat an empty tank?!

That’s what I’m thinking, this could be a low beer intake issue on your part.

^ lol this.
Are you heating empty tanks?

Fresh plastics "off-gas" for months, perhaps years, until they're fully cured, and that off-gassing is accelerated when heated.

You will often have an odor from any electric heater when first used . May or may not be something wrong . Keep an eye on it .

Thanks everyone. Talked to Northwood service guys and they said that the smell is part of the new tanks being used.
