Mount the Burner

Figure 6 - Custom Mounting Plate

Mount the burner to the appliance. The burner specified for packaged equipment will have a flange welded for the required insertion. Follow the appliance manufacturer’s instructions for mounting.

In the absence of instructions, or for retrofits, make sure that the air tube insertion dimension, measured along the side of the air tube from the welded flange to the end of burner air tube, is correct.

Protect the Air Tube from

Overheating

Overheating could cause damage to the air tube and other combustion components leading to equipment malfunction and impaired combustion performance.

yThe end of the air tube must not extend into the combustion chamber unprotected unless it has been factory-tested and specified by the appliance manufacturer.

yThe end of the air tube should be set back ¼” from flush with the refractory inside wall to prevent damage from overheating.

yRefer to the instructions outlined in this section for methods of additional protection.

○If this dimension cannot be achieved, protect the end of the air tube by installing a suitable ceramic refractory material such as a refractory mill board capable of withstanding at least 2300 degrees F. The entry hole diameter in the appliance should be 1” larger than the air tube to facilitate ease of installation and provide adequate protection.

○Referring to Figure 6, if the front plate opening (C) in the boiler is larger than the burner flange bolt circle, then a custom mounting plate (A) of at least 1/4” thickness must be used with a suitable high- temperature refractory material anchored on the fire- side. A suitable high-temperature gasket (B) must be used for an effective seal.

○Attach the plate and gasket to the boiler and tighten the mounting nuts or bolts securely.

○Verify that the air tube is ¼” back from flush (see Figure 2), and there is nothing blocking the flame zone that could cause flame impingement.

Connect Gas Piping

Do Not Use Teflon Tape on

Gas Piping

Damage to gas valve cutoff seals and valve bodies could cause gas leaks and result in asphyxiation, explosion or fire.

yPieces of tape can be cut loose during installation and lodge in gas valves causing cutoff seal problems.

yTeflon tape ‘lubricates’ pipe threads, allowing iron pipes to penetrate too deeply into aluminum valve bodies causing distortion and leakage.

yUse only pipe sealant compounds that are resistant to the gas being used.

All gas piping installation must comply with the latest edition of the

National Fuel Gas Code ANSI Z223.1 (NFPA 54) and other applicable local codes.

The gas supply system must be sized to deliver at least the minimum required pressure to the gas train inlet. Contact your local gas utility for verification of gas pressures, allowable pressure drops, and any local piping code requirements. Refer to Figure 7 for an illustration of a gas piping layout and refer to Table 2 for pipe sizing.
