Checking And Adjusting Co2 Levels; Checking Co2 Level On Units Model 199; Checking Co2 Level On Units Model 399 Up To 1000 - RBI Infinite Energy2 IW199 Installation And Operation Instructions Manual

14 - START-UP
14.8 - Checking and
adjusting CO2 levels
Figure 13-7 lists the correct CO2 ranges
for a appliance running at normal
operating conditions at an altitude
below 2,000 ft (610m). CO2 values
outside of the ranges given in Figure
13-7 may lead to malfunctioning of the
appliance and cause it to prematurely
fail. To check the CO2 value, carry out
a combustion analysis follow Section
14.8.1 or 14.8.2.
14.8.1 - Checking CO2
level on units model 199
WARNING!!!
During this
procedure compare also CO
(carbon monoxide) reading,
with the value given in Figure
13-7. If this is higher, STOP the
appliance and call the Factory
service department (see phone
number on the last cover page).
Failure to comply with this
requirement could result in
severe personal injury, death or
substantial property damage.
1.- If it is not already present, create a
combustion analysis probe site at 8"
after the flue gas exhaust connection
(see Figures 11-9, 11-11 or 11-13,
item "H"). To do so, follow the vent
pipe manufacturers' instruction;
2.- Generate a call for heat and wait
until the appliance is firing;
3.- Gain access to the "Installers' menu"
and set parameter 2010 to HIGH
(see Section 15.11). The appliance
will now run for 20 minutes at high
fire input;
4.- Wait 2 to 3 minutes for the CO2 to
stabilize;
5.- Insert the probe of a calibrated
combustion analyzer into the
combustion analysis probe "H" of
Figures 11-9, 11-11 or 11-13 and take
a flue gas sample;
6.- Compare the CO2 reading with
the high fire range given in Figure
13-7, making sure to use the range
for the gas type in use. If the CO2
reading is outside the specified
range, it must be adjusted operating
on the "E" screw of Figure 14-1. Use
a 2.5mm Allen Wrench to turn the
screw (clockwise to reduce the CO2
level, counter-clockwise to increase
the CO2 level) in small increments
and wait for the CO2 to stabilize to
prevent overshooting the desired
value;
7.- When CO2 level match the value
of Figure 13-7, seal screw "E" with
red paint or nail polish to discourage
tampering;
8.- Set value of parameter 2010 to
LOW. The appliance will now run for
20 minutes at low fire input;
9.- Wait 2 to 3 minutes for the CO2 to
stabilize;
10.- Compare the CO2 reading with the
low fire range given in Figure 13-7,
making sure to use the range for the
gas type in use. The CO2 reading
must be inside the specified range;
If not, STOP the appliance and call
the Factory service department (see
phone number on the last cover
page);
11.- Set parameter 2010 to OFF to
return the appliance to its normal
operating mode;
12.- Close the combustion analysis
probe "H" of Figures 11-9, 11-
11 or 11-13 with a suitable cap
in accordance with the vent pipe
manufacturers' instruction.
WARNING!!!
Once the cap
"L" of Figures 11-9, 11-11 or
11-13 is right in place, with the
appliance at high fire, check
that it is absent from leakage
and is mechanically fixed.
Improper cap fixing can result
in excessive levels of carbon
monoxide which can result
in severe personal injury or
death!

14.8.2 - Checking CO2
level on units model 399
up to 1000
WARNING!!!
During this
procedure compare also CO
(carbon monoxide) reading,
with the value given in Figure
13-7. If this is higher, STOP the
appliance and call the Factory
service department (see phone
number on the last cover page).
Failure to comply with this
requirement could result in
severe personal injury, death or
substantial property damage.
1.- If it is not already present, create a
combustion analysis probe site at 8"
after the flue gas exhaust connection
(see Figures 11-9, 11-11 or 11-13
item "H"). To do so, follow the vent
pipe manufacturers' instruction;
2.- Set parameter 2200 to "HIGH" (see
Section 15.11). Now all burners will
run at high fire for 20 minutes;
3.- Wait 2 to 3 minutes the CO2 to
stabilize;
4.- Insert the probe of a calibrated
combustion analyzer into the
combustion probe "H" of Figures 11-9
or 11-11 or 11-13, and take a flue gas
sample;
5.- Compare the CO2 reading with the
high fire range given in Figure 13-7,
making sure to use the range for the
gas type in use. If the CO2 reading
is outside the specified range, it
must be adjusted operating on each
burner. Set parameter 2200 to OFF
and follow the sequent procedure:
a. Keep the appliance in stand-by
by removing any call for heat
(remove the jumper or any wires
from terminals 10 and 11 inside
the junction box or set the heating
service to off by pushing on the
button up to see the OFF
word);
b. Gain access to the Installer menu
and set parameter 2201 to HIGH
(see Section 15.11). Now the
"Burner 1 (Master) will run for 20
minutes at high fire input;
c. Wait 2 to 3 minutes for the CO2 to
stabilize;
