GENERAL INSTRUCTIONS    The entire text of these instructions must be read and understood, before installing the  appliance. It is the installer's responsibility to do the following:    1. Inform and demonstrate to the user, the correct operation and maintenance of  the appliance, as explained in the Homeowner/User Information and Routine  Maintenance section of this manual.     2. Inform the user of the haz

                        All installations and services must be performed by qualified service personnel.    A. Codes and Clearances:    The following items must be considered when choosing the size and location of  the unit.    1. All local codes and/or regulations take precedence over the instructions  in this manual and should be followed accordingly. In the absence of local  codes, installation must conform to these instructions and the guidelines of the  National Fire Protection Association (NFPA). Two applicable N

                        All installations and services must be performed by qualified service personnel.    5.  Table 1 lists the required minimum clearances to combustible surfaces from  the outer surfaces of the appliance.

                        All installations and services must be performed by qualified service personnel.    The unit is manufactured with runner supports that raise the unit, about 1.25  inches above the mounting base, allowing air circulation beneath the metal  surfaces.  This clearance helps to promote air circulation under the base that  allows the unit to be mounted on combustible materials. This clearance also  helps to reduce metal corrosion caused by a buildup of moisture under the  appliance.     3. The cooling

                        All installations and services must be performed by qualified service personnel.    For proper and safe operation of this appliance, ensure that adequate  clearances around air openings into the burner compartment and the  condenser coil area are maintained. These openings are not to be blocked, or  restricted, in any manner.    5. Measures should be taken to prevent the entry of corrosive chemicals  or vapors to the combustion and ventilation air supply. Such chemicals  include, but are not lim

                        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

Figure 3: Installation of a Condensate Drainage Line on the Evaporator Coil    Condensate from the evaporator is non-corrosive and may be disposed of in any  appropriate manner. The drain connection should be sealed at the appliance  housing to prevent air leakage from the supply air system. Pipe sealant should  be used sparingly on all male pipe threads. Always consult and conform to the  requirements of loc

A readily accessible, design-certified, manual oil shutoff valve, with a non- displaceable rotor member, shall be installed in the fuel oil supply piping  within 6 feet of the appliance.     6. A pipe union, or flanged connection, shall be provided downstream from  the manual oil shutoff valve to permit removal of the appliance oil pump.  Pipe unions must be the ground joint type or flanged-jointed using a

                        All installations and services must be performed by qualified service personnel.    When the oil tank is located below the level of the burner, it is necessary to “lift”  the oil to the burner. A return line should be connected between the fuel pump  and tank. This requires insertion of the "by-pass" plug into the fuel pump. If the lift  (vertical distance between the supply line inlet and the burner) exceeds  approximately 10 feet, a two-stage pump should be installed with a return line.  When
