(continued)
Prepare the appliance
Clean the appliance: Clean the appliance thor-
oughly and seal all joints. Test all electrical com-
ponents 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 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.
Verify combustion chamber dimensions comply
with the minimum dimensions shown in Figure 3b,
page 10. Install or replace chamber liner if required
by the appliance manufacturer. 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 compo-
nents. 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 ce-
ramic fiber refractories or fiberglass insulation,
see WARNING on this page.
Failure to comply with the above could result in
severe personal injury, death or substantial prop-
erty damage.
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 information, 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
fiberglass or ceramic fiber 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 overfire pressure applications: When firing with
positive overfire pressure, do not exceed the pressure
specified in the appliance manual.
Positive overfire pressure reduces maximum burner capac-
ity. See Table 1a 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 28 for required dimensions and bolt locations.
