MOUNTING THE BURNER

The burner is shipped and installed as 3 separate sub- assemblies (Fig. 11):

·front plate and refractory assembly, which is attached to the generator

·burner assembly, which is attached to the frontplate

·gas train and/or oil supply system, which are connected to the burner

Rigging Ð Rigging should be used to position both the front plate assembly and the burner assembly because of their weights. Refer to the shipping container or paperwork for the weight of these units. For the front plate, either webbed strapping placed around the refractory can or a lifting bar in the center opening may be used.

IMPORTANT: Be careful that the assembly does not slip off.

For burner assemblies which do not have lifting lugs, place webbed strapping around a central balance area of the burner.

IMPORTANT: Be careful to avoid damage to small piping, controls, or wiring.

Frontplate and Burner Installation To prevent leak- age of high-temperature combustion gases with this type of forced draft burner, a high-temperature insulating gasket or 1/2-in. Fiberfrax® rope seal is required between the genera- tor and the front plate assembly, and between the front plate and the burner assembly.

Either the gasket or the rope may be provided with the burner, depending on manufacturer's availability.

When using high-temperature insulating rope, it must be wrapped around the ¯ange circumference INSIDE of the mounting studs or bolt holes, with overlapping ends, to provide a complete gas tight seal. Wrapping the rope around the outside of the studs or bolt holes could allow high-temperature gas leakage through the holes in the attached plates.Use either gasket cement or masking tape to hold the ropes in place during installation of the front plate and burner assemblies.

1.Place the high-temperature gasket or insulating rope on the generator mounting ¯ange, inside the bolt holes.

2.Position the frontplate and refractory assembly against the generator mounting ¯ange, with the refractory can ex- tending into the generator ®re tube. Secure in place with washers, nuts, and bolts.

3.Place the high-temperature gasket or insulating rope on the frontplate ¯ange, inside the studs.

4.Position the burner assembly with the burner head ex- tending into the front plate and refractory assembly, mak- ing sure it is plumb. Secure in place with the retaining lugs on the frontplate studs to ensure a rigid mounting. Keep the control panel door closed during the burner in- stallation to avoid damage. Also, it is good practice to remove the ¯ame safeguard chassis during installation and to store it in a safe, dry place until start-up.

5.Measure and fabricate burner support pedestal from pipe(s) with pipe thread on both ends. Screw the support pipe into the support receptacle, and then screw the opposite end into the collar that is welded to the underside of the burner housing. Adjust or shim until the burner is level and ®rmly supported.
