WARNING: This unit is not to be used for temporary heating of buildings, or structures, under construction. Construction dust may enter the appliance or the duct system and cause a fire hazard. Certain chemicals used during construction when burned, form corrosive condensate that can substantially reduce the life of the heating system heat exchanger.

This appliance is shipped completely assembled and internally wired. All electrical wiring has been factory installed and inspected. At the time of installation, the unit will require connection to electric power, fuel oil supply, and supply and return air ductwork. In the event of a shortage of parts or damage, contact Thermo Pride office.

This unit uses a fan-assisted combustion system, consisting of a pressure atomizing, oil burner and combustion air blower, used to push the products of combustion through the heat exchanger system. After installation, the furnace and duct system must be adjusted to obtain a temperature rise of 50°F to 80°F through the unit. (Refer to the rating label located on side panel inside the burner compartment). The installation must conform with local codes or, in the absence of local codes, with the Standard for the Installation of Oil-Burning Equipment, NFPA 31-1997, or the latest edition, and to these instructions. The installation must also comply with CSA B139 for recommended installation practices where applicable.

A. CODES AND CLEARANCES:

The following items must be considered when choosing the size and location of the unit.

In the absence of local codes, installation must conform to these instructions and the guidelines of the National Fire Protection Association (NFPA). Two applicable NFPA installation codes are the National Electrical Code, ANSI/NFPA 70-1999, and Standard for the Installation of Oil-Burning Equipment, NFPA 31-1997. The latest editions of these codes should be consulted.

2.The selection of a heating unit should be based on a rate of heat loss calculation for the residence according to the manuals provided by the Air Conditioning Contractors of America (ACCA) or the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). The heating capacity of the unit proposed for installation should meet or slightly exceed the rate of heat loss for the residence. Over sizing should not exceed 25% of the heat loss calculation.

3.When installed, this unit should be level. If possible, it should be installed in a central location, with respect to outlet registers of the supply air ductwork.

4.A furnace installed in a residential garage must be installed so the burner and ignition source are located higher than 18 inches above the floor. The furnace must also be located or protected to avoid physical damage by vehicles.

5.Definitions of "combustible" and "non-combustible" materials as presented in the latest edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 70, are as follows:
