E. INSTALLATION
1. The Hauck PBG
II
burner can fire in any position. Therefore, it can be installed to fire
through side-walls, roofs or the bottoms of ovens, dryers, or furnaces. Note that
Kromschroder Valvario components may not be installed with the solenoid actuator facing
down. Note that KromSchroder GIK must be installed with the spring tower side facing
down.
2. The
PBG
II
burners will bolt to the oven or furnace wall. Prepare the oven wall appropriately
to support the weight of the burner and any other associated components. Install the burner
combustor tube so that it is properly insulated in the furnace wall. For walls thicker than the
standard length of the combustor alloy tile or in cross-flow applications the use of a straight
or 90° auxiliary firing tube may be required (See Step 5).
3. For air heating installations where the burner will fire into a chamber under negative
pressure, spacers may be installed between the burner mounting bracket and the
oven/furnace wall to draw secondary air past the firing tube.
4. On installations where there is a positive pressure within the combustion chamber, the
opening in the oven or furnace wall should be at least 1 inch (25mm) larger than the burner
combustor tube/tile. Pack the space around the alloy tile with ceramic fiber suitable for the
temperatures involved. Ceramic fiber packing should not extend past wall thickness.
Installation of the high temperature gasket between the burner mounting plate/flange and
the oven or furnace wall is recommended for all positive pressure ovens or furnaces.
5. On installations using the auxiliary firing tube, the area between the burner alloy tile and
firing tube should be packed with ceramic fiber. Ceramic fiber packing should not extend
past the wall thickness or the end of the alloy tile (See Figure 1).
NOTE
All rotating components were balanced from factory at a level meeting ISO 1940-2. A variety
of external causes such as handling, installation, or misalignment may cause imbalance prior
to use. To ensure the intended long life of the equipment and components, and to meet
warranty requirements, equipment and vibration levels should be checked by experienced
personnel and trim balanced if no longer meeting ISO 1940-2 requirements. Under no
circumstances should equipment with excessive vibration be operated at the risk of damaging
that equipment or the personnel operating it.
IMPORTANT
Using the PBGII basic burner configurations in chambers operating with vacuum or
positive pressure will create conditions preventing normal operation according to
these instructions. The high and low fire settings for gas and air will change along
with the operating window of the burner. Under more extreme conditions, special
components may need to be selected in order to manage burner performance.
