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 baffles 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 flanges. 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 Differential" type humidifiers (preferably a power humidifier) should be used. If the round inlet duct of the
humidifier 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 humidifier and the opening in the plenum such that the effective opening for the humidifier will
approximate 4" in diameter. This will reduce the volume of short-circuited air through the humidifier connection
(Please see Fig. 9).
