11 CG4 Burner Manual
Section: INSPECT/PREPARE INSTALLATION SITE
The burner’s firing rate is the input rating. If it is
given in GPH of oil, multiply by 140,000 to get BTU/
Hr for gas or by 140 to get MBH.
○ The burner’s firing rate must be no more than 5%
higher than the appliance’s stated input rate (based
on industry tolerance) and no more than 10% lower
than the appliance’s stated input rate (based on the
potential for low stack temperature condensation
hazards).
○ Determine the burner’s appropriate chassis and air
tube components from Table 5, being sure to apply
the altitude adjustment from Table 1 on Page 4,
if applicable.
○ Verify that the chassis has the correct air band and
baffle (if required)
○ Verify that the air tube has the correct head and
nozzle (markings are visible without disassembly)
and static plate (there is only one choice, and it is
visible without disassembly).
○ Verify that you have the correct fuel orifice for the
intended firing rate ( Table 5) – sizes are stamped on
the orifices
○ Examine the appliance’s combustion chamber and
compare its dimensions to the rate-appropriate line
in Table 4 to verify that the chamber is large enough
to handle the flame size.
○ Examine the appliance’s mounting dimensions and
compare them to those of the mounting flange on
the air tube, making sure that the distance from
the flange to the furnace end of the burner head
provides for the ¼” set-back shown in Figure 11 on
Page 16.
Carbon Monoxide
Hazard
DO NOT INSTALL a Beckett gas burner and air
tube combination with a firing rate more than 10%
lower than the appliance name plate’s input BTU
rating. The appliance and vent system could be
damaged due to condensation, leading to flue gas
leakage.
DO NOT INSTALL a Beckett
gas burner and air tube
combination with a firing rate more than 5% above
the appliance name plate’s maximum input BTU
rating.
Prepare the Appliance
Breathing Hazard
Ceramic fiber or Fiberglass insulation
Ceramic fiber materials, such as chamber
liners, may contain carcinogenic particles
(crystalline silica) 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 crystalline silica. Actual job requirements
for 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
operations are necessary, wear extra protection to
prevent breathing dust.
Wash work clothes separately from other laundry.
Rinse clothes washer thoroughly afterwards to
prevent contamination of other clothing.
NIOSH First aid procedures:
y Eye exposure - irrigate eyes immediately
y Breathing - fresh air
Asbestos Hazard
NEVER attempt to retrofit an
appliance containing asbestos.
Contact a professional to remove the
asbestos prior to installation. If
unsure call a qualified contractor to
verify if asbestos is present.
Thoroughly clean appliance heat exchanger and replace
damaged combustion chamber materials, if necessary.
○ Seal all clean-outs, burner mounting plate and vent
pipe connections.
○ Verify all appliance operating and safety controls are
functional and operating correctly. Replace any that are
questionable.
○ Verify all wiring and controls comply with National/Local
codes and authorities having jurisdiction.
