Questions about repairing old wall heater
I have an 4' X 2' direct vent wall heater. It is mounted on the wall and the vent goes right thru the wall to the outside.
Is it better just to replace the whole unit instead of just the gas valve? The gas valve hasn't worked in a year, but I understand a new gas valve can cost 2 or 3 hundred dollars, while I can buy a new furnace plus the valve for about 500. I'm thinking the old burner might be old and rusty with a bad flame, and I don't want to reuse the old pilot and burner gas lines.
Is mounting these direct vent wall heaters pretty standard? Do they have basically the same dimensions, use the same sized hardware for the venting pipe? I believe the top vent wall heaters are pretty standardized in that way.
