GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Use the factory supplied wiring schematic booklet to connect power to the boiler. The schematic booklet also depicts how to interconnect the boiler controls, using the supplied wire harness. Before connecting any harnesses, the control panel and wire duct must be attached to the boiler using the supplied fasteners.There are prepunched holes in the jacket panel to help locate and install these components. Use as many fasteners as required to secure control panel and wire duct to front jacket panel. Prepunched holes are for locating purposes only and may not securely fasten components. Run the wire harnesses inside the plastic wire duct between termination points, see Figure 102. Instructions for cutting, locating and mounting the wire duct can be found in the electrical book. The wire harnesses' identification and mounting location information can also be found in the electrical wiring diagram book.

Thermostat Installation

If a thermostat is to be used to control the boiler always follow the instructions included with the thermostat. Proper location of the thermostat will ensure efficient trouble-free operation of the boiler. Mount the thermostat to an inside wall at a height approximately five feet above the floor. Avoid placing the thermostat in areas that will not provide an accurate measurement of the room temperature. Locating the thermostat behind a door, in an alcove, close to a source of thermal radiation or in a drafty area will cause poor or sporadic heating.

BOILER OPERATION

WARNING: Before proceeding read and fully understand the instructions contained in this manual. Do not attempt to operate this boiler if it has not been installed in accordance with the guidelines set forth in this manual. Failure to comply with this warning can result in extensive property damage, severe personal injury or death!

Water Boilers

Fill the boiler and all of the radiation with water to the required system pressure. Completely purge the system of air and adjust the system pressure as needed.

Steam Boilers

Fill the boiler with water to a level 1" below the normal water level line of 33 1/4". Clean the newly installed sections as outlined below:

CAUTION: Do NOT use any petroleum based cleaners to clean the boiler or the hydronic seals will be damaged!

1.Pipe the skimmer tapping on the front of one of the end sections to a floor drain using 1 1/2" pipe.

2.Adjust the boiler water level until water begins to flow out of the skim piping at a slow rate.

3.Fire the boiler and maintain a water temperature of

180°F to 200°F. It may be necessary to cycle the boiler.

4.Adjust the water feed to prevent the build up of pressure within the boiler. Continue the skimming process until the discharge runs clear.

5.Shut the boiler off and allow the boiler to cool to

100°F. Remove the skim piping and plug the tapping. Open the blowdown valve and flush the boiler until the discharge runs clear.

6.Close the blowdown valve and fill the boiler with water to a level 1" below the normal water level line.

7. Check the traps and vents for proper operation.
