COMBU TION TE T/ADJU TMENT
The installer MUST perform a complete combus-
tion check to ensure the following combustion lev-
els are met at high and low input firing rates and the
burner is operating at optimum conditions.
The combustion testing and adjustments
must be performed by a qualified installer,
service agency or the gas supplier. All com-
bustion measurements must be perform with
calibrated equipment to ensure proper read-
ings and accuracy.
Failure to perform a complete combustion
test at both high and low input rates may
result in incomplete combustion and the pro-
duction of carbon monoxide, which can
cause severe personal injury, death or sub-
stantial property damage.
MCBA Instructions
1. Manually place the boiler into High fire mode
by pressing the MODE button with “+” button
simultaneously on the control panel display
while in the standby (STBY) mode.
The control panel will display an H followed
by the current boiler temperature when
placed into High fire test mode.
2. If the combustion levels during High fire are
outside the recommended combustion settings
adjust the THROTTLE SCREW (see Fig. 4) as
follows:
Counter-clockwise adjustment of the THROT-
TLE CREW at high fire:
O2decreases and C02increases
Clockwise adjustment of the THROTTLE
CREW at high fire:
O2increases and CO2decreases
Table 1: Recommended Combustion Levels
3. Once the combustion level is set at High fire,
manually place the boiler into Low fire mode by
pressing the MODE button with “-” button
simultaneously on the control display while in
the standby (STBY) mode.
