Warranty

When installed according to Metal-Fab Masonry Chimney Liner installation instructions, as prescribed by Underwriters Laboratories Standard 1777, Metal Fab Inc. warrants its aluminum chimney lining systems for two (2) years from the date of end-user installation. Metal-Fab warrants the Masonry Liner Kits to be free from defects in material and workmanship. During this period, Metal-Fab agrees to replace such defective components without charge. Liability under this warranty shall be limited to the replacement of the liner and accessories found to be defective and shall not include removal costs, re-installation costs, or any other costs.

This warranty shall continue for an additional thirteen (13) years on a pro-rated basis with the proration commencing with the original purchase date. It is the purchaser's responsibility to establish the date of the original installation of the product. Deviation from the installation and use instructions included with the liner will void the warranty. Since wood, coal, and oil can cause creosote, dirt, and debris to build up within a masonry chimney, the installer must be sure that the inside of the masonry chimney is properly cleaned before installing the aluminum liner. No chimney that is not structurally sound should be relined.

Since local or state building codes and fire officials may have installation restrictions, as well as inspection requirements, it is advisable that the installation and maintenance of chimney lining systems be performed by an experienced and certified professional. Important: Metal-Fab Aluminum Chimney Liners are to be used with natural gas or propane gas fuels only.

In order for this Limited Warranty to remain in effect: this liner system must not be exposed to chemically contaminated air; this product and the heating system to which it is connected must be inspected yearly by a qualified technician; a written record of inspections must be maintained by the end user; and system deficiencies must be remedied at time of discovery.

Ordered new, got it used
Format: Paperback
Paid for a new book. It arrived very clearly used. It is in decent condition but it is frustrating paying that much for something to arrive used with damage.

A much needed quench to the thirst of our societies internal struggles.
Format: Hardcover
The Ruthless Elimination of Hurry: This book is a refreshing surge of truth and wisdom, full of profound teachings from a heart posture of love for those of us suffering from modern day hyper-culture. Thank you for the great read, John Mark Comer. I would highly recommend to others to read this book: To slowly and fully read this book. After the first chapter, I was confronted with so many modern day realities that have become the new daily norms. Those of course brought forth personal conviction and a new hope for the change that would be to come! It was hard to believe that the entire book would be so filling - BUT IT WAS. The Ruthless Elimination of Hurry makes an articulate yet simple stride to sober today’s society to the truth. The truth that the generalized hurried, stressed out, and “got no time” culture we’ve created, is bringing us death. Not life. JMC leads a church that I regularly visit. I do not come because I have an overflowing abundance of time and want to go to church twice on Sundays. No, I go because everytime I attend Bridgetown Church, I am filled with deeper insight into God’s word and such joy and peace! Why joy and peace you may ask? Because our God is a God of JOY and PEACE. When you get to know him and his truths are spoken to us and over our life we begin to know our Father and find joy, rest, and many other fruits in him. JMC and his pastoral team are doing something beautifully radical in today’s society - Choosing Jesus’ rhythm over today’s western hyper obsessed, and greed driven culture. I began reading this book during a month of my life that I felt like I was spiritually under warfare and was having a hard time not just spiritually, but also emotionally and physically. I began reading the Ruthless Elimination of Hurry because I have read all of JMC’s books and I trust that his writings would be only an encouragement for me. This book is full of life giving knowledge that he has collected through his discipline to the way, reading other authors, historical and present, that too were trying to practice the way, and oh yeah - where they got it all - Jesus, the man teaching us all the way! This read was a leveling reminder of my discipleship to Jesus and how to step back into his beautifully easy rhythm that is, no doubt, in opposition to the rhythm of current society, social media, and today’s lure of entertainment. I am twisting and turning my way back into the path God has laid so lovingly before us to stride beside him. & just like that! I am back to the fruit of the spirit spilling joy and love out of me! I cried once in this novel. As I read the last three pages. Please listen why - Because JMC so graciously and intentionally laid in front of us Jesus’ teachings in a language we all follow, a way to heal our souls, bring families back together, unite friendships, & ultimately live life to the fullest. I was filled with a passionate excitement to again believe that WE CAN live in the way of Jesus, walking in his slow and easy footsteps. In my opinion, this is John Mark Comer’s best novel yet. I feel as though we have a modern day apostle helping us to disciple under Jesus. Ready and willing to teach those who choose to listen and leading the masses into the loving way of Jesus. I bought this book for myself. & then I bought a couple for a couple close friends. I imagine I will continue as I see the need in many struggling in a chaotic and over crammed life. This is a refreshing reminder to step back into the path less traveled. I encourage you to read it and see what kind of fruit these practices can bear in your life.

Definitely a really good book to read
Format: Hardcover
So far an amazing book I haven’t finished it, but I’m so into it and I know for a fact it’s gonna be good from the beginning to the end. It does make me reflect on my life, and it has opened my eyes to a lot of things regarding being in a hurry, and how if the enemy can’t get us to sin, he will make us busy. Must read.
