M. SETTING TEMPERATURE RISE

The GMD1-60N and GMD1-80N is designed and wired at the factory for a heating blower speed that should result in an approximate temperature rise of 70°F.

The blower motor is wired on low speed for heating mode of the GMD1-60N.

The blower motor is wired on medium low speed for heating mode of the GMD1-80N.

The temperature rise through the furnace may vary depending on the duct system, elevation, heating value, etc. for each installation.

After 10 to 15 minutes of continuous operation, the temperature rise through the

furnace must fall within a range of 55°F to 85°F. If the outlet or supply duct temperature is too high, check to make sure the return air filter is clean, the return air registers are free from obstruction, the outlet registers are properly adjusted and clear, and the supply and return air ducts are open.

The circulating air blower is not moving enough air if the supply air temperature is still too high. Before proceeding further, turn off the power supply to the furnace and remove the blower door. The speed of the blower must be increased by changing the speed tap from the motor (see wiring diagram). This is accomplished by locating the control panel attached to the blower housing and switching the blower lead, which should be connected to the “Heat” terminal on the White-Rodgers 50A65-143 control, with one of the higher speed blower leads attached to a terminal marked “Park”. Be sure to attach any unused blower leads to a terminal marked “Park”. Replace the blower door and turn on the power supply.
