Kit for venting water heaters through existing connectors

 Tjernlund Products introduces a new Chimney Stack Assist Kit (Model CSA1) that allows water heaters to be vented through existing connectors and oversized chimneys, eliminating the need to install a chimney liner. Use of a mechanical assist fan protects against condensation callbacks and flue gas spillage problems. The fan installs fast, operates quietly and plugs into a standard electrical outlet.
