Section: MOUNT THE BURNER
Connect Gas Piping
Install the test cock tee, its plug, and the union (provided
with the burner) into the supply piping and connect them
to the burner valve and manifold ( Figure 12).
Gas supply piping must be
structurally supported
independant of the burner. The burner manifold and
gas valve are not designed to support piping loads.
Mount the Burner
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.
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.
1. Verify the Burner’s Insertion Depth
The end of the air tube should be set back ¼”
from flush with the refractory inside wall to prevent
damage from overheating (See Figure 11).
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
manufacturer.
2. Bolt the burner to the appliance using the factory-
mounted flange and gasket.
3. Provide support under the burner if required.
Some Local codes require the
burner to have a stand. If this is
required use Beckett Part #5685 Pedestal Kit.

Provide Over-pressure Protection
The National Fuel Gas Code, ANSI Z223.1 (NFPA
54) and ASME CSD-1 require that if gas pressure
entering the building exceeds the rating of any gas
train component an overpressure protection device
must be installed.
