When installing a new gas-burning appliance, different specifications may require a specific chimney liner size to operate properly and safely. Often a new high-efficiency furnace is installed and leaves behind (orphans) a water heater – which is now venting by itself into an old, larger lining. Many times it’s recommended to install a properly sized liner to accommodate the remaining appliance.
DRF partners with Lindemann to provide safe and reliable solutions for instances when a chimney liner is a necessary addition to a water heater installation.
Often when having a new natural gas or propane water heater installed, a new chimney liner is recommended, or even mandated by code. This requirement is a critical safety consideration for your property and addresses several issues.
