Handling
OXYTHERM®FHR burners are shipped as complete units.
Handle burners with care, using proper equipment, during
unpacking, transport, lifting and installation. Any impact
on the burner could result in damage.
Burner mounting
The views on page 2 show two possible methods for
mounting and holding an OXYTHERM®FHR burner block
and frame assembly in place.
Typical burner mounting arrangement
1) Furnace wall
2) Melter wall
3) By others
4) Piping support

Alternate burner mounting arrangement
Burners should not be installed in a down-fired position.
The primary objective is to seal the burner block in the wall
of the furnace and support the weight of any system
piping.
The burner block sits on the sill or wall. The block must rest
flat on the sill or wall without rocking to allow weight to be
equally distributed. Failure to do so could result in
cracking and/or block failure. If burner port holes are too
large, appropriate material shims may be used to align the
burner.
Burner block failure could result from external forces and
stresses transmitted to the burner through the piping.
Under no circumstances should burner be the only
support for the piping. Flexible connections are
recommended in all piping to reduce piping stresses and
alignment/shifting problems. Installation of such
connectors at certain key spots in the oxygen or gas
manifolding can prevent damage to the burners from
uneven thermal expansion.
The opening of the furnace wall should provide a minimum
of 1/16” clearance on all sides. High temperature furnace
sealant or other appropriate material should be used
between burner block and furnace wall.
IMPORTANT
For maximum burner life, burner housing and
associated parts must be protected from hot
gases.
Burner installation procedure
Read the entire installation procedure before proceeding
with the installation of oxygen-fuel burners.
WARNING
Failure to follow the proper installation sequence
noted below could result in damage or
destruction of vital burner components.
Cooling oxygen or air flows should be present at all
times when the burner housing and metal
components are mounted to a hot furnace.
To prevent damage in transit, the fuel inserts, mounting
gaskets and burner housing may be packed separately. In
most cases, the burner will be shipped assembled. The
housing may be removed from the burner block mounting
plate to allow installation of the block/mounting plate
assembly only into the furnace wall.
NOTE: A 3/4” (or 12 mm) socket wrench is required for
mounting nuts. A manual speed wrench is recom-
mended for quick and easy mounting of the
burner housing.
• If fuel insert is shipped inside burner housing, remove
the fuel insert and set aside in a protected area.
• Install service plate over housing flange and secure
plate to housing using T-bolts provided.
• Pre-pipe quick-connect devices to the combustion
oxygen, fuel and atomizing connections (if required) on
the burner housing and burner fuel inserts.
• Install block/plate/housing assembly into furnace wall.
• Establish cooling flow of air or oxygen through the
housing during furnace heat up.

CAUTION
Staged oxygen control valve must be placed in
position #1 as shown in Technical Catalog
32M-02012 to provide optimal cooling to the
burner.
View port
A view port to observe burner flame is essential to inspect
flame aspect. Locate the view port downstream of the
flame, looking back to the burner block. Make sure the
complete flame can be evaluated.
Support burner oxygen and gas piping
The OXYTHERM®FHR burner shall not be used as support
for the piping to the burner. Gas and oxygen piping shall be
supported in such a way that no additional loads will be
created on the burner. Unsupported piping puts stresses
on the block/housing assembly.
Flexible connections are typically recommended for all
OXYTHERM®FHR installations for both fuel and oxygen to
prevent transferring mechanical loads or vibrations to the
burner’s ceramic parts. Quick connect/disconnect devices
are recommended on the oxygen and fuel connections to
ease fuel nozzle switching.
OPERATING INSTRUCTIONS
Instructions provided by the company or individual
responsible for the manufacture and/or overall installation
of a complete system incorporating MAXON burners take
precedence over the installation and operating
instructions provided by MAXON. If any of the instructions
provided by MAXON are in conflict with local codes or
regulations, please contact MAXON before initial start-up
of equipment.
WARNING
Read the combustion system manual carefully
before initiating the start-up and adjustment
procedure.
Verify that all of the equipment associated with and
necessary to the safe operation of the burner
system has been installed correctly, that all pre-
commissioning checks have been carried out
successfully and that all safety-related aspects of
the installation are properly addressed.
1) Service plate
2) Cooling flow
3) Staged oxygen
control valve (set to
position #1 for
optimal cooling)

Start-up
Typical ignition sequence
IMPORTANT
OXYTHERM® FHR burners do not include means
for self ignition. Burner ignition procedure is the
responsibility of the end user, according to appli-
cable local, state and national codes. Burner igni-
tion should only be attempted at minimum firing
rates (see capacity charts or contact MAXON) to
prevent pressure surge in the fired chamber.
Checks during and after start-up
During and after start-up, check the integrity of the
system. Check all bolted connections after first firing (first
time on temperature) and retighten if necessary.
Burner adjustment and control
Oxygen-fuel burners require accurate control of both fuel
and oxygen for optimum performance. Piping to individual
burners should include control valves for both oxygen and
fuel. In addition, flow meters for oxygen and fuel capable of
local or remote readout are required for proper burner
adjustment.
CAUTION
Oxygen should only be used with approved
materials, properly cleaned pipe and equipment,
and specially designed systems.
Ordinary materials can be extremely flammable in
the presence of oxygen and air enriched with
oxygen.
Oxy-fuel burners cannot be set up and operated properly
using only pressure requirements for adjustment. Fully
metered oxygen and fuel control systems are required for
safe and optimum performance.
MAINTENANCE INSTRUCTIONS
WARNING
The OXYTHERM® FHR burner is provided with
quick release clamps to allow for rapid change-
over between gas and oil firing.
ustomer-specific procedures for shut down and
blocking of fuel gas and oxygen supply to the
burner must be developed and adhered to prior to
attempting removal and changing of fuel inserts.
Only trained and qualified service and
maintenance personnel should perform this
operation.
Safety requirements
Regular inspection, testing and recalibration of
combustion equipment according to the installation
manual is an integral part of its safety. Inspection activities
and frequencies shall be carried out as specified in the
installation manual.
Perform the following activities at least annually as part of
a recommended preventative maintenance routine:
• Inspect burner internal parts for wear and oxidation.
• Inspect associated control instruments and devices for
function with particular attention to all safety
permissive switches.
• Perform leak tests on fuel shut-off valves according to
any schedule established by the authority having
jurisdiction.
Visual inspections
Regular visual inspection of all connections (air and fuel
piping to the burner, bolting of the burner to the block) and
burner flame size and aspect are essential.
Recommended spare parts
Keep local stock of operationally critical parts. Contact
MAXON for a complete list of recommended spare parts
for your specific application.
