Installation Requirements 

 
1.

 

All installation work must be performed by trained, qualified contractors or technicians.  Electro 
Industries, Inc., sponsors installation and service schools to assist the installer.  

Visit our web site at 

electromn.com for upcoming service schools.

 

 

 

WARNING

 

ALL ELECTRICAL WIRING MUST BE IN ACCORDANCE WITH NATIONAL ELECTRIC CODE 
AND LOCAL ELECTRIC CODES, ORDINANCES, AND REGULATIONS. 

 

 

WARNING

 

OBSERVE ELECTRIC POLARITY AND WIRING COLORS.  FAILURE TO OBSERVE COULD 
CAUSE ELECTRIC SHOCK AND/OR DAMAGE TO THE EQUIPMENT. 

 

 

CAUTION

 

This unit can only be used for its intended design as described in this manual.  Any internal 
wiring changes, modifications to the circuit board, modifications or bypass of any controls, or 
installation practices not according to the details of this manual will void the product warranty, 
the CSA/us certification label, and manufacturer product liability.  Electro Industries, Inc., 
cannot be held responsible for field modifications, incorrect installations, and conditions which 
may bypass or compromise the built-in safety features and controls.

 

 
2.

 

If this is a Dual Heat system, this product relates only to the addition to the furnace ducting system 
external to the gas or oil force air furnace.  The owner/ installer assumes all responsibility and/or 
liability associated with any needed installation of the gas/oil furnace, fuel system, flue, chimney, etc.  
Any instructions or comments made within this manual (or factory phone assistance) relating to the 
gas/oil furnace are provided as comments of assistance and “helps” only. 

 

 

CAUTION

 

This unit shall not be operated (either heating section or blower) until the interior of the 
structure is completed and cleaned.  This also means all duct work must be complete with 
filter, etc.  Both manufacturers’ warranties are void if this unit is operated during structure 
construction.

 

 

 

CAUTION

 

Hazards or unsafe practices could result in property damage, product damage, severe personal 
injury and/or death.

 

 
3.

 

Remember, safety is the installer’s responsibility and the installer must know this product well 
enough to instruct the end user on its safe use. 

 

Safety is a matter of common sense - - a matter of thinking before acting.  Professional installers have 
training and experienced practices for handling electrical, sheet metal, and material handling 
processes.  Use them.
