Description
The Tjernlund Products GPAK-1 Vent System For Gas Heater is designed for gas-fired heating equipment with capacities up to 250,000 BTU and work as a replacement for the GPAK-1T assembly. It is used in commercial systems to safely vent combustion gases from furnaces, boiler and other fan-assisted gas heaters through sidewall venting configurations. The system supports proper draft control and exhaust airflow management in commercial and residential heating applications where conventional chimney venting may not be practical. Its role within the HVAC system is to maintain safe operation by directing flue gases outside the setups while supporting consistent combustion performance and system efficiency.
