Here are the pictures right side up.
1. Love this gravity furnace because it is soooo quiet
and vintage.
2. Gone through 2 vintage gas valves that failed and finally a modern new valve and it now works perfectly.
3. Spent many hours dissembling, cleaning and
painting to make as "like new" as possible.
4. The purpose of the post was to help others with a similar issue and share ideas.
So...
What do you think of the vent cover? Good idea? Bad idea? Unexpected problems?
Great to get some relevant feedback. Thanks.
