The Toyotomi Heat Exchanger for Laser 60AT and Laser 60AT-W, part number 20479944, is a replacement internal heat transfer component designed to remove combustion heat from the burner chamber and transfer it into the heater’s airflow path. It is engineered to meet original equipment specifications so it installs directly in place of a worn, corroded, or damaged heat exchanger in compatible Toyotomi Toyostove heater models. A properly functioning heat exchanger is essential for efficient heat transfer and helps maintain safe combustion by directing exhaust gases away from the heater’s internal structure.
This heat exchanger is intended for use during repair or service when the original exchanger shows signs of deterioration, rust, blockage, or heat fatigue that can reduce heating performance or contribute to unsafe operation. When malfunctioning, symptoms can include reduced warm air output, visible rust buildup, or abnormal combustion odors. Installation should follow the heater’s service manual and parts diagram to ensure the heat exchanger is positioned correctly and sealed, maintaining proper airflow through the heater’s combustion and circulation systems.
What’s Included: One (1) Toyotomi heat exchanger for Laser 60AT and Laser 60AT-W heater models.
Installation Limits: For replacement use only on compatible Toyotomi heater models; install with the heater powered off and confirm all mounting points and seals are secure to prevent exhaust leaks.
Compatibility: Compatible with Toyotomi Toyostove Laser 60AT and Laser 60AT-W heaters requiring this heat exchanger configuration.
Laser 60AT, Heat Exchanger is located next to Canopy.
