If the control is to be installed in a furnace, follow items 1 through 4 before bringing the control or yourself in contact with the furnace. Put all used and new controls into containers before touching ungrounded objects.
Page 7 - -The furnace is controlled by a thermostat. It may not be “hot wired” to provide heat continuously to the structure without thermostatic control.
Page 8 The requirements for combustion and ventilation air depend upon whether or not the furnace is located in a space having a volume of at least 50 cubic feet per 1,000 Btuh input rating for all gas appliances installed in the space.

NOTE: It is recommended that the perforated supply- -air duct flanges be completely folded over or removed from furnace when installing the furnace on a factory- -supplied cased coil or coil box. To remove the supply- -air duct flange, use wide duct pliers or hand seamers to bend flange back and forth until it breaks off.

The furnace airflow rates are provided in Table 5- -AIR DELIVERY- -CFM (With Filter). When a furnace is installed so that the supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by duct(s) sealed to the furnace casing and terminating outside the space containing the furnace.
