Professional Installation

and Service Required

Incorrect installation and mishandling of start- up could lead to equipment malfunction and result in asphyxiation, explosion or fire.

yThis burner must be installed and prepared for start- up by a qualified service technician who is trained and experienced in commercial gas burner system installation and operation.

yCarefully follow the wiring diagrams, control instruction sheets, flame safeguard sequence of operation, test procedures and all appliance manufacturer’s directions that pertain to this installation.

yIf any of these items are not clear or are unavailable, call Beckett at 1-800-645-2876 for assistance.

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 RWB recommended maximum pipe lengths for good light-off (Figure 8A/B).

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.

Delayed Ignition, Explosion

and Fire Hazards

This is a direct spark ignition burner and by code requirements must have a primary control with a 4-second flame establishment period. Exceeding 4 seconds could result in delayed ignition, explosions and fire.

Always verify the primary control has a 4-second flame establishment period by carefully following the control manufacturers’ configuration instructions.

Example: Honeywell RM Series requires clipping and removing the JR1 resistor.

Start-up Checklist

Verify the following before attempting to start the burner.

1. General

○Carefully read and become familiar with the 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.).

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 Replacement Parts Illustration 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 3 and Figures 10A and 10B to insure that the burner air damper is 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 4) and properly installed (see Propane Restrictor Installation instructions).

○Before operating insure that all protective cover
