10 year old Viessman installed incorrectly replaced and relocated to garage with Ideal logic 30kw(7 year manufacturers warranty).The flue on the older boiler was installed incorrectly and spilling carbon monoxide into garage! Luckily for customer not into the house. It is so important to get an RGII to carry out your installations and annually service your boiler. Don't take a chance and always think: SAFETY FIRST!
