Section: Prepare the Burner for Start-up

Start-up checklist

Verify the following before attempting to start the burner:

1. General

○Carefully read and become familiar with the CG10 Manual, Flame Safeguard Control Instructions, sequence of operation, pertinent wiring diagrams, gas system layout, insurance requirements, other controls and valve literature pertinent to the installation.

○Follow the appliance manufacturer’s start-up procedures (when available).

○Inspect the combustion air supply and exhaust venting and verify that they are free of obstructions and installed and sized in accordance with all applicable codes.

○Notify appropriate personnel to schedule start-up (gas utility, owner, operators, subcontractors, etc.).

2. Gas Supply Piping

○Insure that the gas piping is properly sized and has been inspected by the gas utility, leak tested at all joints, and purged.

○To protect the gas train and controls, insure that a drip leg or dirt pocket has been properly installed.

○Insure that the fuel gas being supplied is compatible with the burner specification and is available at the correct regulated pressure. (See burner name plate and specification sheets).

○Insure that the vent lines for the diaphragm valves have been run to the outside and properly terminated.

○Use R.W. Beckett recommended maximum pipe lengths for good lightoff (Figure 8).

3. Electrical

○Insure that all wiring has been completed and complies with the National Electric Code NFPA 70 and local requirements.

○Refer to Figure 1 and verify that the electrical supply to the burner matches the voltage specification on the label.

4. Boiler or Appliance

○Insure that the flue passages and combustion area have been thoroughly cleaned and are in good condition.

○Set the breech damper to the required position for system operation.

○Fill the appliance with water (boilers).

○Check all safety and operating controls for correct application, installation, wiring, and operation.

○Insure that the maximum capacity of the appliance is compatible with the specified burner input firing rate.

5. Burner - See Figure 10 for familiarization

○Insure that the gas burner model and capacity meet the requirements for the installation.

○Insure that the gas train meets operating specifications, all safety codes and insurance requirements.

○Refer to Table 2 and Figure 11 to insure that the burner air shutter and band are positioned for initial start-up preliminary settings.

○Insure that the burner is securely mounted in the appliance with the pressure firing plate and all gaskets in place for pressurized chamber applications.

○For propane-firing burners, insure that the propane restrictor has been correctly selected for your burner model (see Table 3) and properly installed (see Propane Restrictor Installation instructions).

○Before operating insure that all protective cover plates, enclosures and guards are in place and securely fastened.

○When available, refer to the appliance manufacturer’s instructions and install the burner accordingly.

6. Test instruments

○The following calibrated test equipment is required to properly install the appliance. Whether these are included in one kit or are individual test components, they should be calibrated and in good working order.

○A combustion analyzer capable of measuring oxygen (or carbon dioxide), carbon monoxide, stack temperature, ambient temperature, and appliance efficiency.

○Electrical multi-meter capable of measuring voltage, ohms, amps, and DC micro-ammeter for measuring the flame signal. These could be included in one meter or separate meters, but should be calibrated and accurate.

○Calibrated manometers and gauges capable of measuring all pressure ranges in the gas supply and appliance draft. This could typically range from a few psi to 0.01” W. C.
