DANGER
The burners covered in this manual are designed to mix fuel with
oxygen and burn the resulting mixture. All fuel burning devices
are capable of producing fires and explosions when improperly
applied, installed, adjusted, controlled or maintained.Do not
bypass any safety feature; fire or explosion could result.Never try
to light the burner if it shows signs of damage or malfunction.
WARNING
The burner is likely to have HOT surfaces. Always wear protec-
tive clothing when approaching the burner. Honeywell products
are designed to minimize the use of materials that contain
crystalline silica. Examples of these chemicals are: respirable
crystalline silica from bricks, cement or other masonry products
and respirable refractory ceramic fibers from insulating blankets, boards, or gaskets. Despite these efforts, dust created
by sanding, sawing, grinding, cutting and other construction
activities could release crystalline silica. Crystalline silica is
known to cause cancer, and health risks from the exposure to
these chemicals vary depending on the frequency and length of
exposure to these chemicals. To reduce the risk, limit exposure
to these chemicals, work in a well-ventilated area and wear approved personal protective safety equipment for these chemicals.
CAUTION
This manual gives information for the use of these burners for
their specific design purpose. Do not deviate from any instructions or application limits in this manual without written advice
from Honeywell.

PRODUCT DESCRIPTION
Forehearth oxygen gas burners are small, nozzle mixing burners designed to be inserted into the forehearth to provide temperature homogeneity throughout the glass by increasing the heat of the glass melt
in the area near the forehearth wall where cooling occurs more rapidly.
These burners consist of a 300-series stainless steel gas tip
and a 300-series stainless steel or oxygen nozzle. They produce a short, bright flame intended to keep the temperature of the glass near the forehearth wall, where cooling is
most rapid, at the same level as the middle of the glass bed.
Forehearth burners use one size body for all nozzle sizes making for
easier maintenance and greater capacity flexibility. They fire natural
gas and come with a unique block to fit the exact requirements of
the burner.
BENEFITS
– Cooler running burner and block for increased reliability and
product life
– No maintenance design for less downtime and lower mainte-
nance costs
– Simple design, easy to configure and order for your specific
application
– Easy to set up and operate

Forehearth Oxy/Gas and Air/Gas Burners
➔ The oxy/gas forehearth burners consist of a stainless steel body
that is universal for all oxygen and gas nozzle sizes.
Forehearth burners are mounted directly into the forehearth burner
➔
blocks with no special mounting equipment required.
Burner Installation and Operation
Initial Forehearth Start-Up
➔ Burners should be out of the forehearth during furnace heatup.
1
Connect the oxygen (or air) and gas supply lines to fittings on the
burner.
2
Make sure all systems are checked and ready.
3
Make sure all burner isolation valves are closed.
4
Open oxygen and gas to the zone controls.
5
Allow oxygen and gas to flow through the burner to ensure gas
and oxygen lines are purged.
6
Allow chamber to reach a minimum temperature of 1500 ºF (816
ºC) to ensure the auto-ignition point of natural gas has been
reached before inserting burners and opening oxygen and gas
valves.
➔ For oxygen burner starts, it is best to allow the furnace to rise to
a temperature between 1652 ºF (900 ºC) to 1832 ºF (1000 ºC),
if possible.
➔
It is suggested that this initially be in an area away from the
heat-up burner.
7
Open the oxygen valve for the burners installed in step 7.
➔ With oxygen flowing, set the oxygen flow per burner to the flow
in the following table based on burner model:
Oxygen Flow Chart
Model Oxygen Flow, scfh (Nm3/hr)
FH1350 70 (1.99)
FH0935 50 (1.42)
FH0517 24 (0.684)
➔ Turndown is 4:1 on all models
8
Open the natural gas valve.
9
Start the natural gas flow and bring up to a flow per burner from
the following table based on the burner model:
Model Fuel Flow, scfh (Nm3/hr)
FH1350 35 (0.997)
FH0935 25 (0.712)
FH0517 12 (0.342)
10
Check burners to verify ignition and listen for a “screaming” or
“squealing” sound. If the burners are making these sounds, open
or close the gas to the burner until the sound goes away. If the
sound persists, shut off gas flow to the zone and check burners
PrimeFire FH · Edition 11.19 · EN
for damage as well as to verify gas and oxygen/air connections
are not reversed.
➔
During the initial light off/heat-up, it is better to run the flame
slightly gas rich.
11
Ensure heat-up burner flame is not pushing forehearth burner
flame into the side of the block bore.
12
Add or reduce gas and oxy/air to keep the furnace temperature
on the heat up curve.
13
Heat-up burner turndown and removal
– It is recommended to start with burners away from the heat-up
burner first.
– As forehearth burners are turned on, lower the gas flow to the
heat-up burner.
– When the flow to the heat-up burner is low enough, shut off the
gas flow and remove the burner.
➔
Pay attention to the forehearth pressure during this procedure
and close off the stack as needed.
➔ With oxy firing, the pressure will drop off significantly. Add fuel/
oxygen to hold temperature, then add burners as necessary.
14
Repeat steps 3-15 for each zone.
15
Remove a burner and check the appearance of the flame.
16
Add burners as needed but ensure the flow of oxygen and gas
remain below the maximum and above the minimum flow rates
for each burner.
Burner Mounting
The block must rest flat on the sill or wall without rocking to allow
the weight to be evenly distributed. Failure to do so could result in
cracking or block failure. If burner openings are too large, shims
may be used to align the burner. Avoid applying any compressive or
tensile forces to the ceramic portions of the burner as this may cause
premature failure. The burner opening should provide a minimum of
1/16” clearance on all three sides. High temperature furnace sealant
or packing should be used between the burner and wall.
Basic dimensions of the PrimeFire FH, showing both the Oxygen
Inlet and Fuel Inlet orientation to the burner and block
assembly.
➔ It is recommended that the PrimeFire FH be mounted such that
the piping is anchored to a fixture to allow pressure on the burner/
block connection in order to ensure ideal performance.

Cooling Air Flow
Removal of the burner nozzle is recommended when the burner is
out of service. If removal is not possible, or not chosen, cooling flow,
either clean, dry air, nitrogen or oxygen, must be used. Typical compressed air systems contain lubrication oils, which will contaminate
oxygen-clean environments and cannot be used for cooling flows
without special treatment. Cooling air provided by plant process air
fans is one possible source.
Hot Installation
➔ Minimum temperature of 1500º F (816º C))
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 nozzle is inserted.
1
Connect gas and oxy (or air) supply lines to burner fittings.
2
Make sure all systems are checked and ready.
3
Make sure burner isolation valves are closed.
4
Open oxygen or air valve to the burner.
5
Slowly open the gas valve to the burner to ignite the flame.
6
Open gas valve to the burner to set flow to desired rate.
Burner Ignition
CAUTION
The PrimeFire FH burner does not have self ignition capability.
It is the responsibility of the end user and service personnel
attempting start-up to confirm that ignition temperatures appropriate for the fuel used are present inside the furnace where the
burner is located. In cases where manual ignition from the outside is required, provisions shall be made in the furnace wall adjacent to the burner. Burners should be started up at minimum
fuel and oxygen flows (see page 3 (Burner Installation and
Operation) to prevent sudden pressure rise in the fired chamber.
➔
Set correct gas and oxygen flow before attempt of burner ignition.
Flow meters for oxygen and gas flow measurement should be
used 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.
Flame Lengths
Flame lengths are given at high fire and minimum fire for each capacity. The flame length in this design has a linear relationship with
the fuel flow rate. The higher the fuel flow rate at a given capacity
the longer the flame

MAINTENANCE
➔
The PrimeFire FH requires very little maintenance, if any. However,
preventative maintenance is the key to a reliable, safe and efficient system. The following are suggested guidelines for periodic
maintenance. Burners in severe environments or operational
conditions should be checked more frequently. Spare burners
not in use should be completely drained and stored vertically to
prevent rusting.
➔
NOTE: The periodic, monthly, and yearly lists are an average
interval. If your environment is dirty, the intervals may be shorter.
Check with local authorities having jurisdiction regarding their
recommended maintenance schedules.
Periodic Checklist
1
Continuously monitor gas and oxygen flows.
2
Check flame shape to ensure there is nothing blocking the gas
or oxygen nozzles which could cause damage to the burner and
the burner block.
3
Remove burners and inspect tips for signs of carbon build-up as
well as checking for any damage to the burner blocks that could
result from dirty nozzles/ incorrect flows, or loose oxygen nozzles
at least four times per year.
4
Clean all burner nozzles on a routine basis once per month and
when required by flame appearance.
5
Check for proper oxygen/gas pressures (refer to Technical Infor-
mation for Oxy-Fuel Burner PrimeFire FH).
6
Test all the system alarms for proper response signals.
7
Test the manual gas shut-off valves for proper operation.
Yearly Checklist
1
Test (leak test) safety shut-off valves for tightness of closure.
2
Test pressure switch settings by checking switch movements
against pressure settings and comparing these with the actual
impulse pressure.
3
Inspect impulse piping for leaks.
4
Clean and inspect all burners.
