dperry Posted May 2, 2010 Report Share Posted May 2, 2010 Hi everyone, I'm not an inspector but have noticed an issue with my gas heater so I hope you won't mind me posting here about it. I have an old Holly (like Williams) gas forced air wall furnace and today I noticed a small pile of flakes in the vent at the top of the unit, below the blower. I assume this is probably the flue vent. The flakes are rusty on one side and sort of dull metallic silver-grey on the other and they instantly turn to dust when touched. There's also a lot of dust around them. Their proximity to the intake blower is what concerns me since they are so light and dusty and because of the age of this thing and the likelihood of lead paint. God forbid if some lead dust got sucked in and blown all over my living room. However, I'm thinking this may be cold galvanizing compound/paint, which is used to treat steel in corrosive conditions. In that case, it would be mostly zinc. I don't know about lead content, though. Unfortunately, it looks like these Williams-type wall furnaces have no filter. I'd like to know what most likely origin of the flakes is and if they are anything to be concerned about. I can only guess at the age of the furnace but it looks '60's. Thanks in advance for any advice you can give. Dave Quote Link to comment Share on other sites More sharing options...
