Must have your OT filter engaged if you think this is a woodworking forum.

Does anyone know which Selkirk Metalbestos adapter I need to
transition a Modine Hot Dog heater with a 3" appliance exhaust to 5"
type B (gas) round double wall pipe? I purchased their 3" x 5"
increaser and it's actually 3 ½" in diameter.

Ask in alt.hvac. Why ask in a woodworking group?
