HE ATER MOUNTING
Cut out heater opening at a minimum distance of 6 inches from the furnace. Center the opening on the plenum. Provide
slots for insertion if baes are installed. (Please see Fig. 8).
The 6 inch minimum dimension from the top of the furnace to the heater opening in the plenum may be increased.
If increased, 14 inch minimum dimensions in Fig. 3 must be increased accordingly.
Slip the heater element into the opening. Make sure that the opening and slots are entirely covered by the heater
mounting anges. Secure the heater to the plenum by means of metal screws.
HUMIDIFIER
DO NOT USE PAN & PL ATE TYPE HUMIDIFIERS WITH THE WATER RESERVOIR INSIDE THE WARM AIR SUPPLY
PLENUM.
Only "Pressure Dierential" type humidiers (preferably a power humidier) should be used. If the round inlet duct of the
humidier is connected on the hot side of the heater, it is strongly recommended to insert a reducing ring between the
round inlet duct of the humidier and the opening in the plenum such that the eective opening for the humidier will
approximate 4" in diameter. This will reduce the volume of short-circuited air through the humidier connection
(Please see Fig. 9).
