Where appliance instructions differ from this manual, follow the appliance instructions.
1. Prepare site • prepare burner • mount burner
(continued)
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
firing rate than the appliance rating. Do not install a burner
with a firing 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 flue-gas containing joints. Seal
all connections to the vent piping or breeeching.
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 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 fiber 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.
When cleaning the appliance or working with ceramic fiber
refractories or fiberglass insulation, see WARNING on this
page.
Ceramic fiber or
Fiberglass insulation
Ceramic fiber materials, such as chamber liners,
may contain carcinogenic particles (chrystobalites)
after exposure to heat. Airborne particles from
fiberglass or ceramic fiber 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-fitting
clothing, gloves and eye protection. Use a NIOSH
N95 certified respirator. This respirator meets
requirements for protection from chrystobalites.
Actual job requirements or NIOSH regulations may
require other or additional protection. For informa-
tion, refer to the NIOSH website, http://www.cdc.
gov/niosh/homepage.html.
Ceramic fiber removal: To prevent airborne dust,
thoroughly wet ceramic fiber with water before
handling. Place ceramic fiber materials in a plastic
bag and seal to dispose.
Avoid blowing, tearing, sawing or spraying fiber-
glass or ceramic fiber materials. If such operations
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 overfire pressure applications: When firing with posi-
tive overfire pressure, do not exceed the pressure specified
in the appliance manual.
Positive overfire pressure reduces maximum burner capacity.
See Table 1 notes for estimated reduction in burner capacity
with pressurized firing.
Failure to comply could result in severe personal injury, death
or substantial property damage.
Check bolt locations
Verify that the burner flange bolt layout matches that of the appliance. See
page 19 for required dimensions and bolt locations.
