GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Burner Installation

1.DO NOT install damaged or badly corroded burners, replace them.

2.Install the burners by sliding the rear of the burner tube into the slot located in the base rear panel. Slide the burner into the slot far enough so that the burner bracket clears the orifice on the manifold. Pull the burner back onto the orifice making sure that the notch in the crimped portion of the burners engages the rear burner base panel locking it into place.

3.Replace the front grill(s).

Heat Exchanger Cleaning

The burners should be removed to protect them from falling rust and scale. Follow the BURNER REMOVAL instructions in this manual.

1.Remove the front grill(s) and front access panel(s).

2.Remove the clean out covers and insulation, Figure

55& 56.

3.Clean each flue passage with a wire brush.

4.Vacuum out the burner base and clean and inspect all of the components. Replace any damaged or badly corroded parts.

5.Replace the insulation and clean out covers,

6.Replace the front access panel.

7.Install the burners following the BURNER INSTALLATION procedure outlined in this section.

8.Replace the front grill(s).

Vent System

Thoroughly inspect the vent system for any signs of blockage, corrosion or leakage. Immediately replace any unsound vent system piping.

Controls

Use the BOILER OPERATION and BOILER CHECKING AND ADJUSTMENT sections of this manual for reference.

1.Check the thermostat or operating controls for proper operation.

2.A float type low water cutoff device must be flushed

out.

3.The relief valve should vent water when the test lever is lifted. It should not weep or discharge water at normal system pressure. NEVER try to clean or repair the relief valve! If the valve fails to operate properly, replace it!

4.The aquastat high limit controls the maximum water temperature in the boiler. It is adjustable from 140°F (60°C) to 240°F (116°C). If the water temperature reaches the set temperature before the demand for heat has been met, the aquastat high limit should shut the boiler off. The water temperature should never exceed the maximum set point of 240°F (60°C). The aquastat high limit cannot be repaired. If it fails to function properly replace it.

5.Visually check the pilot and main burner flames to ensure proper operation, see Figure 103 & 104.

WARNING:Yellow, floating flames indicate a lack of combustion air. Do not operate the boiler until the problem is solved or severe personal injury or death may occur!
