We are building a home and will be installing a chimney for our new Englander NC-30 stove. We have a good builder but he doesn't have a ton of experience w/wood stove chimney installations. It looks like we will need to deal w/an online supplier. I have 2 questions. What are suggestions as to a manufacturer that has a reputation as a provider of good quality products that are also a good value? Second question, is there an online supplier that has a reputation for excellent service and very knowledgeable tech staff?
