Thermo Products 30 User Manual

All installations and services must be performed by qualified service personnel. 
 

 
 
In addition, long term exposure of building materials to combustion products may 
cause discoloration of material surfaces and corrosion or degradation of 
materials. The preferred installation location will allow combustion products to 
freely escape the immediate area of the appliance and rapidly disperse into the 
atmosphere, without being drawn back into the appliance or a nearby structure. 
 
To prevent combustion products from entering a structure, the vent terminal must 
expel combustion products away from any point of entry.  The minimum 
acceptable distances from the vent terminal to points of entry to a building are 4 
feet horizontally from, and 1 foot above, or at least 4 feet below, any window, 
door, or gravity air inlet into the building.  And, 3 feet or more above any forced 
air inlet to the building located within 10 feet of the terminal.  
 
Once the unit is installed in a suitable location, the installer must mount the vent 
terminal to the appliance. Two sheet metal screws are installed in the unit for this 
purpose. Refer to Figure 2 for a sketch of the correctly assembled vent terminal. 
 

 

 
This appliance is equipped with a ¾ inch PVC stubbed drain extension for 
connection of a condensate line to the evaporator drain pan. A condensate 
removal line should be fabricated and attached to the PVC drain extension, refer 
to Figure 3. The condensate drain line must be pitched downward to drain 
properly. The drain line can also be trapped and the condensate pumped to a 
suitable drain. If the drain line clogs, when the air conditioner is operating, the 
condensate tray under the evaporator coil will fill with water.  As a result, water 
may enter the appliance housing and the supply air ductwork to the structure.
