Mount The Burner - Beckett CG10 Manual

U urner
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.
Figure 6. Custom Mounting Plate
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 combus-
tion performance.
• The end of the air tube must not extend into the
combustion chamber unprotected unless it has been
factory-tested and specified by the appliance manu-
facturer.
• The end of the air tube should be set back ¼" from
flush with the refractory inside wall to prevent dam-
age from overheating.
• Refer 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 gas=
ket (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.

All gas piping installation must comply with the latest edi-
tion 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 pres-
sures, 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 1 for pipe sizing.
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.
• Pieces of tape can be cut loose during installation
and lodge in gas valves causing cutoff seal prob-
lems.
• Teflon tape 'lubricates' pipe threads, allowing iron
pipes to penetrate too deeply into aluminum valve
bodies causing distortion and leakage.
• Use only pipe sealant compounds that are resistant
to the gas being used.
