LOWER ELAY IMINGS The integrated control module on 96% models provides a selectable heat off delay function. The heat off delay period may be set to 100 or 150 seconds by cutting the jumper on the control module. The delay is factory shipped at 150 seconds but may be changed to suit the installation requirements and/or homeowner preference.
