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

 

2. The furnace must be kept free and clear of insulating material. The furnace area should be 
examined when the furnace is installed or when insulation is added.  Insulating materials may be 
combustible. 
 
3.  For proper and safe operation the furnace needs air for combustion and ventilation.  Do not 
block or obstruct air openings on the furnace, air openings to the area in which the furnace is 
installed, or the spacing around the furnace. 
 
4.  This furnace is equipped with a blocked vent shut off system.  In the event that an obstruction 
or restriction occurs in the vent pipe or termination, the furnace will shut off and the control will 
flash an error code.  This prevents the formation of hazardous gas products and prevents any 
release of exhaust gas into the home.  If the furnace fails to operate, contact a qualified service 
agency. 
 
5.  Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the 
furnace before shutting off the electrical supply. 
 
6.  Do not use this furnace if any part has been under water.  A flood damaged furnace is 
extremely dangerous.  Attempts to use the furnace can result in fire or explosion.  A qualified 
service agency should be contacted to inspect the furnace and to replace all gas controls, control 
system parts, electrical parts that have been wet or the furnace if deemed necessary. 
 
7.  Visually examine the furnace at the start of the heating season and monthly during the heating 
season. 
 

(a.)  All flue gas carrying areas external to the furnace (i.e chimney, vent connector) are 
clear and free of obstructions. 
 
(b.)  The vent connector is in place, slopes upward and is physically sound without holes 
or excessive corrosion. 
 
(c.)  The return air duct connection is physically sound, is sealed to the furnace casing, 
and terminates outside the space containing the furnace. 
 
(d.)  The physical support of the furnace is sound without sagging cracks, gaps, etc., 
around the base so as to provide a seal between the support and the base. 
 
(e.)  There are no obvious signs of deterioration of the furnace. 
 
(f.)  The pilot and burner flames are in good adjustment (by comparison with pictorial 
sketches or drawings of the main burner flame and, if applicable, the pilot burner flame).
