Figure 1 Vent and vent connector installation
Inspect, repair and/or replace vent system
Do not install this burner unless you have veried
the entire vent system and the appliance are in good
condition and comply with all applicable codes.
The vent and chimney must be sized and constructed
in accordance with all applicable codes. If intended for
use with an oil burner as well, the vent system must
comply with relevant codes for both gas and oil ring.
Appliances equipped with a gas conversion burner are
treated as fan-assisted appliances.
The vent system must not be pressurized unless the
vent piping and vent system are designed accordingly.
The vent must provide draft at all times (negative pres-
sure in vent).
Do not install or use an existing manual damper in the
vent connector or vent.
Do not connect the appliance vent connector to a
chimney or vent serving a replace, incinerator or
solid-fuel-burning apparatus.
In a cold climate, do not vent into a masonry
chimney that has one or more sides exposed to
the outside. Install a listed stainless steel liner to
vent the ue products.
A defective vent system could result in severe personal
injury, death or substantial property damage.
Vent/chimney sizing
• Follow all local codes when sizing the vent and chimney
• Refer to the appliance manufacturer’s manual, when available,
for venting recommendations.
Prepare vent/chimney
• Secure all metal vent joints with screws, following the vent
manufacturer’s instructions. Seal all joints in the vent system
and chimney. Repair masonry chimney lining and repair all
mortar joints as needed.
• Where draft uctuations are likely, install a double-acting barometric draft regulator in the vent piping. (The damper must be
located in the same space as the appliance.) Install a manual
reset spill switch in the top of the draft regulator outlet. Wire the
switch into the appliance limit circuit to shut off the appliance/
burner if sustained downdraft should occur. Refer to the appli-
ance manufacturer’s instruction manual for recommendations
regarding the need for a barometric draft regulator.

Figure 2 Locating & sizing air openings
Verify combustion/ventilation air openings
Installing the burner/appliance in a space that does not provide
enough air for combustion and ventilation can result in severe
personal injury, death or substantial property damage. Follow
all applicable codes and guidelines below to ensure space
has sufcient air openings.
Large spaces
For appliances located in basements, ventilated crawl spaces or other
large areas, no additional air openings should be necessary. Exception: If
the building construction is unusually tight (see National Fuel Gas Code
for denition), you will need to provide air openings into the building if ap-
pliance air comes from inside. Provide one opening within 12 inches of the
ceiling, and one opening within 12 inches of the oor. Size each opening to
provide free area (after deduction for louvers) of 1 square inch per 1,000
Btuh input of all fuel-burning appliances in the building.
Conned spaces — air from inside building
If air openings connect to areas inside the building, provide two openings,
one within 12 inches of the ceiling, the other within 12 inches of the oor.
Each opening must have a free area (after deduction for louvers) of 1 square
inch per 1,000 Btuh of all appliances in the space. If the building construc-
tion is unusually tight (see National Fuel Gas Code for denition), you will
need to provide air openings into the building. Provide two openings sized
and located as for the openings into the boiler space.
Conned spaces — air from outside
If air openings connect directly to outside, provide two openings, one within
12 inches of the ceiling, the other within 12 inches of the oor. Each opening
must have a free area (after louver deduction) of:
• If directly through side wall: 1 square inch for each 4,000 Btuh of all
appliances in the space.
• If through vertical ducts: 1 square inch for each 4,000 Btuh of all appli-
ances in the space.
• If through horizontal ducts: 1 square inch for each 2,000 Btuh of all
appliances in the space.
Optional outside air connection
For spaces not tted with large enough air openings, you may be able to
apply the optional burner cover kit (RESCVR5S) with Outside Air/Direct Vent
kit (50433KIT) to provide outside combustion air to the burner. You must
use a vent outlet/air inlet termination approved by the appliance manufac-
turer. Refer to the appliance and outside air kit manuals for instructions.
You will also have to apply this option if the appliance space may contain
corrosive contaminants, such as laundry products, paints, varnishes or
other chemicals.
Even when using the optional outside air kit, make sure the
space provides enough ventilation to prevent overheating of
the appliance, burner and controls. If there is risk of over-
heating, you must install ventilation air openings sized large
enough to provide air for cooling the equipment. Failure to
provide ventilation can result in severe personal injury, death
or substantial property damage.

etc.
• Conrm with user that the area will be kept free of these materials at
all times.
Prepare the appliance
Burner input: Install a gas burner sized for the normal input
rating of the appliance. Do not install a burner with a higher
ring rate than the appliance rating. Do not install a burner
with a ring rate more than 10% lower than the appliance
rating. The appliance and vent system could be damaged
due to condensation.
Seal the appliance: Seal all ue-gas containing joints. Seal
all connections to the vent piping for breeching.
Clean the appliance: Clean the appliance thoroughly and
seal all joints. Test all electrical components and verify the
relief valve works (boilers only).
Verify combustion chamber dimensions comply with the
minimum dimensions shown in Figure 3, page 7. Install or
replace combustion chamber liner if required by the appliance
manufacturer. The burner must not extend into the combus-
tion chamber. The end of the burner air tube must be within
¼” of the inside face of the combustion chamber. If the space
around the burner air tube is more than ¼”, wrap the burner
air tube with minimum 2300-°F-rated ceramic ber blanket
to seal off the gap.
Repair or replace damaged appliance components.
Inspect the appliance thoroughly. Follow appliance manufac-
turer’s guidelines for repair or replacement of any component
found defective.

Ceramic ber or
Fiberglass insulation
Ceramic ber materials, such as chamber liners,
may contain carcinogenic particles (chrysto-
balites) after exposure to heat. Airborne particles
from berglass or ceramic ber components have
been listed as potentially carcinogenic by the
State of California. Take the following precautions
when removing, replacing and handling these
items.
Avoid breathing dust and avoid contact with
skin or eyes. Wear long-sleeved, loose-tting
clothing, gloves and eye protection. Use a NIOSH
N95 certied respirator. This respirator meets
requirements for protection from chrystobalites.
Actual job requirements or NIOSH regulations
may require other or additional protection. For
information, refer to the NIOSH website, http://
www.cdc.gov/niosh/homepage.html.
Ceramic ber removal: To prevent airborne dust,
thoroughly wet ceramic ber with water before
handling. Place ceramic ber materials in a plastic
bag and seal to dispose.
Avoid blowing, tearing, sawing or spraying
berglass or ceramic ber materials. If such op-
erations are necessary, wear extra protection to
prevent breathing dust.
Wash work clothes separately from other laun-
dry. Rinse clothes washer thoroughly afterwards
to prevent contamination of other clothing.
NIOSH First aid procedures:
Eye exposure — irrigate immediately
Breathing — fresh air.
Prepare appliance for burner mounting
The universal ange supplied with EZGas Pro burners
is for ring chambers with negative or positive overre pressure. The ange should be sealed with high

Air tube insertion length (UTL)
• Usable air tube length (UTL) is the distance from mounting ange to end of air
tube. Verify that the end of the air tube will be ush with, or no more than ¼ inch
short of, the inside of the appliance combustion chamber front wall when the
burner is mounted. See Figure 3 and Table 1 below for further information.
Diffuser plate
• Verify correct diffuser plate (item 2, page 3). Compare diffuser plate listed on air
tube label with diffuser plate listed in Table 1.
Gas orice drill size
• The gas orice is drilled through a plate in the end of the orice nipple (see item
6, page 3). Read the factory-drilled orice size on the label attached to the burner
air tube (see item 1, page 3) near the blower housing end. If the gas orice size
is not correct for your application, or if the label is illegible for any reason, check
the orice size directly and redrill orice or replace if necessary, as follows (next
page).
Approx. Air Band SettingOrifice Drill Size
for Insertion Depth
Burners with welded flange have fixed
insertion depths. Verify the insertion depth is
correct for the appliance. On burners with
adjustable flanges, the Usable Tube Length
(UTL) available for setting the insertion depth
varies with air tube length:
Tube Length UTL min. UTL max.
10" 1 3/4" 3 1/2"
12 1 3/4" 5 1/2"
14 1 3/4" 7 1/2"
Firing rate should be within +/- 5% of rated input for the appliance. High altitude applications: The maximum burner input at sea level is 275,000 Btuh.
Reduce this capacity by 4% per 1,000 feet above sea level. Example- max. capacity at 5,000 feet is 220,000 Btuh (20% reduction). Pressurized firing:
Note 1
Note 2
Note 3
Note 4
Maximum burner input decreases with increasing overfire pressure. Assume a reduction in maximum burner input of approximately 5% at 0.1 w.c. and
10% at 0.2 inches w.c You will have to increase the air band opening to compensate for the increased pressure. Follow the procedures given in this
manual to check combustion with instruments to determine the correct air band setting. Do not fire into a chamber with pressure higher than 0.2 inches
w.c. and never fire at a higher pressure than recommended by the appliance manufacturer.
Once the orifice is drilled, minor adjustments to the firing rate can be achieved by adjusting the gas valve outlet pressure between 3.2" and 3.8" w.c. If
the rate remains too low, re-drill the orifice with a 1/64" larger bit (for details, see Make Final Burner Adjustments in Section 4 of this manual.)
For BTU ranges that are covered by both the 9-Slot Diffuser Plate and the A or B Diffuser Plate, it is likely that either diffuser will work, but one may
provide better combustion. The 9-slot's short flame pattern favors appliances with shorter combustion chambers.
Use this as the starting setting only. Adjust air band setting, if necessary, after performing combustion testing (see page 13).

• Unplug wire harness from combination gas valve.
• Remove the combination gas valve (item 20, page 3) and the orice
nipple (item 6, page 3). Remove the orice nipple from the gas valve.
• Read the correct orice drill size from Table 1, page 7. Then check
actual orice size using that size twist drill bit.
• If gas orice is smaller than required, redrill the orice to the correct size, if necessary.
• If gas orice is larger than required, obtain a replacement orice
nipple from Carlin. If necessary, drill the orice hole in the replacement orice nipple to the correct size.
Drill the orice carefully, avoiding drill wobble. Wobble will
cause the orice to be over-sized. The orice nipple should
be secured in a vise, if possible, to ensure it is steady during the drilling process.
• Write the orice size on the orice nipple label (or on the French
label attached to the burner for Canadian installations).
• Replace the gas valve and piping, using only pipe dope listed for use
with liqueed petroleum gases. Make sure the arrow on the orice
nipple label points in the direction of gas ow.
Flame rod and ignitor electrode
• Inspect the burner from air tube end. Flame rod should extend
through the diffuser plate as shown in Figure 4. Ignitor electrode
should be ush with inner face of diffuser plate as shown.
• The ame rod and ignitor electrode must not touch the diffuser or any
grounded metal surface at any point. The ame rod and electrode
should be as close as possible to the centers of the diffuser holes. If
either the ame rod or electrode is closer than 1/16” to the diffuser,
remove assembly (see page 15 for removal instructions and verify
dimensions per Figure 5). Bend the end of the ame rod or ignitor
electrode as required. Replace assembly and check spacing again.
Continue adjusting as necessary until neither rod nor electrode is
