Combustion air/ventilation openings
General
Installing the burner/appliance in a space that does not
provide enough air for combustion and ventilation can re-
sult in severe personal injury, death or substantial property
damage. Follow all applicable codes and guidelines below
to ensure space has sufcient air openings.
Exhaust fans and negative pressure conditions — Isolate the
boiler room from areas subject to negative pressure. Size
combustion air openings to ensure neutral air pressure in
the boiler room whenever the burner operates.
Make sure the space provides enough ventilation to prevent
overheating of the appliance, burner and controls. If there is
risk of overheating, 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.
The space and combustion air supply must not contain
corrosive contaminants, such as laundry products, paints,
varnishes or other chemicals.
Sizing air openings
Follow all applicable codes and the appliance instruction manual (when
available) to size combustion air openings. Use the following guidelines
when appliance instructions are not available.
• All air from inside building (building must be well-ventilated):
Size air openings for a free area (after louver deduction) of at least 1
square inch per 1,000 Btuh input of all appliances in the space.
• All air through openings to outside:
Locating air openings
Follow all applicable codes and the appliance instruction manual (when
available) to size combustion air openings. Refer to Figure 2 when ap-
pliance instructions are not available.
Free area estimating
When specic information on the free area of louvers is not available,
estimate free area as:
• wood louvers — free area = area times 0.25.
• metal louvers or grilles — free area = area times 0.60.
• screens, when used must be no smaller than ¼ inch mesh.
Motorized vent dampers
Wire the vent damper end switch to prevent operation of the burner until
the air opening louvers are fully open.
Combustion air/ventilation opening checklist
• Verify that openings are unobstructed.
• Verify that appliance space and air source spaces are free of:
– Gasoline or other ammable liquids or vapors.
– Combustible materials.
– Air contaminants, such as laundry products, paint, thinner, varnish,
etc.
• Conrm with user that the area will be kept free of these materials at all
times.
Verify clearances
• Verify that the burner/appliance will maintain all clearances to combustible
walls or oor and all clearances required for service/maintenance as
required in the appliance manual and applicable codes.

Prepare the appliance
Clean the appliance: Clean the appliance thoroughly and
seal all joints. Test all electrical components and verify the
relief valve works (boilers only).
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 or breeeching.
Verify combustion chamber dimensions comply with the
minimum dimensions shown in Figure 3, page 7. Install or
replace chamber liner if required by the appliance manu-
facturer. The burner must not extend into the combustion
chamber. The end of the burner air tube must be within ¼"
of the inside face of the 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
manufacturer’s guidelines for repair or replacement of any
component found defective.
When cleaning the appliance or working with ceramic ber
refractories or berglass insulation, see WARNING on
this page.
Failure to comply with the above could result in severe
personal injury, death or substantial property damage.
Ceramic ber or
Fiberglass insulation
Ceramic ber materials, such as chamber liners,
may contain carcinogenic particles (chrystobalites)
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 certied 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
Positive overre pressure applications: When ring with
positive overre pressure, do not exceed the pressure
specied in the appliance manual.
Positive overre pressure reduces maximum burner ca-
pacity. See Table 1 notes for estimated reduction in burner
capacity with pressurized ring.

2. Install gas piping from meter to combination gas train
Code compliance
The burner/appliance installation must comply with codes listed on page 2
and any other locally applicable codes.
Piping from gas meter to burner
Connect from the gas supply to the burner gas train inlet using
new, clean black iron pipe and malleable iron ttings only. Do
not use copper, brass, cast iron or galvanized pipe or ttings.
Provide support for gas piping. Do not rest the weight of the
gas piping on burner gas train.
Provide a support for the burner gas train.
Apply pipe dope sparingly at all joints. Use only pipe dope listed
for use with propane gas. Do not use pipe sealing tape.
Do not hold the gas valve with pipe wrench. Use crescent
wrench or other smooth-jawed device. Do not overtighten.
Failure to comply with above could result in severe personal
injury, death or substantial property damage.
1. If possible, install a new gas line directly from the gas meter. If you are
using an existing gas line, verify it is clean and in good condition, and
verify it is large enough to handle the load of all connected appliances.
2. When branching from a common gas line, do not tap off from the bottom
of horizontal sections — only from the side or top.
3. Install a main manual shutoff valve, sediment trap and ground joint union
near the burner combination gas valve connection as shown in Figure 10.
4. If the burner is installed inside an appliance jacket, install the main manual
gas valve and sediment trap external to the jacket.
5. Size piping (or verify size) using Table 2. You will nd additional information
on gas line sizing in the National Fuel Gas Code, NFPA 54/ANSI Z223.1,
or B149.1/B149.2 Installation Code for Canadian Installations.
Gas supply pressure — natural or propane
• Maximum supply pressure:14 inches w.c.
• Minimum supply pressure: 5 inches w.c.
Do not expose the gas train to gas pressure in excess of 14
inches water column. Higher pressure could damage the valve
seat, resulting in potentially hazardous condition. When pres-
sure testing piping at higher pressures, disconnect burner from
gas line before testing.
If the gas supply pressure can exceed 14 inches water col-
umn at any time, you must install a lockup type gas pressure
regulator in the gas supply piping, ahead of the main manual
gas valve installed at the burner.
