CLEANING INSTRUCTIONS FOR
ELITE HEATING BOILER
®
*Before beginning this procedure, you must have on
hand the following items:
– a nylon, stainless steel or brass brush (not
steel)
– “Rydlyme” (recommended for best
r e s u l t s ) ( a v a i l a b l e o n l i n e

1. Shut down the Elite Heating Boiler ® by using the
following steps:
a. Close the gas valve, shut down the unit
and wait for the unit to be cool to the
touch
b. Disconnect the condensate piping from
the outside connection, (not from the
Elite Heating Boiler ® side) , so the flow
from condensate reservoir can be
observed.
c. Disconnect electrical connections from
the gas valve, spark electrode and flame
rectification probe and combustion blow-
er.
d. Remove the (4) screws on the aluminum
¾” NPT connector on the right side of the
gas valve.
e. Disconnect the wiring connected to the
combustion blower motor.
f. Remove the (6) 10MM nuts from the
burner plate assembly.
g. Pull the entire burner plate assembly with
blower still attached towards you, while
removing or pushing aside any wiring to
allow the removal of the assembly.
2. Using a spray bottle filled with the recommend-
ed product “RYDLYME” or “CLR”, spray liberally
on the coils, making sure the solution penetrates
and funnels down through the condensate sys-
tem. If the condensate system is blocked, let the
chemical penetrate for at least 15 minutes or
until it drains.
3. Use the nylon, stainless steel or brass brush (do
not use steel) and scrub coils to remove any
buildup, then vacuum the debris from the coils.

“Crystalline silica inhaled in the form of
quartz or cristobalite from occupational
sources is carcinogenic to humans
(Group1).”:
Avoid breathing dust and contact with skin and
eyes.
• Use NIOSH certified dust respirator (N95). This
type of respirator is based on the OSHA
requirements for cristobalite at the time this
document was written. Other types of respirators
may be needed depending on the job site
conditions. Current NIOSH recommendations
can be found on the NIOSH website at
http://www.cdc.gov/niosh/homepage.html.
NIOSH approved respirators, manufacturers, and
phone numbers are also listed on this website.
• Wear long-sleeved, loose fitting clothing,
gloves, and eye protection.
Apply enough water to the combustion chamber
lining to prevent dust
Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer
thoroughly.
NIOSH stated First Aid.
Eye: Irrigate immediately
Breathing: Fresh air.
