7.
Switch boiler circuit breaker in the
control panel to the ON Position (1000
only).
8.
Close the manual gas valve between the
automatic gas valve and the blower
inlet.
9.
Cycle the boiler. The boiler should
lockout on gas pressure failure. In this
case it should be the low gas pressure
switch.
10.
Reset the low gas pressure switch and
gas pressure lockout.
11.
Increase the high gas pressure switch
setting to 14” w.c.
12.
Cycle the boiler. The boiler should
lockout on flame failure or ignition
failure. (Boiler may recycle once if there
was an ignition failure. Repeat step 12.)
13.
Reset the flame failure lockout and
decrease the high gas pressure setting to
1” w.c.
14.
Cycle the boiler. The boiler should
lockout on gas pressure. In this case it
will be the high gas pressure switch.
15.
Open the manual gas valve between the
automatic gas valve and the blower
inlet.
16.
Reset the high gas pressure switch and
gas pressure lockout.
17.
Cycle the boiler. The boiler should
establish main flame.
18.
If flame is not established reset the
flame failure lockout and repeat step 17.
(Consult with the factory for assistance
if flame cannot be established after 3
attempts.)
19.
Check that O2 levels are within a safe
operating range. (4.5% to 7.0%)
20.

21.
Once boiler has reached high fire rate,
check that O2 levels are within a safe
operating range. (4.5% to 7.0%)
22.
Adjust supply gas pressure between 4”
w.c. and 14” w.c. as measured at the ball
valve tapping outside of the boiler top
jacket panel.
23.
Adjust the O
2
level so that it is within
4.5 to 7.0 % at high fire with all jacket
doors installed and front cabinet door
closed.
a.
For best efficiency, standard O2
should be set to 4.5% to 4.6%.
b.
For boilers specified to be less than
20ppm NOx adjust the O
2
level
within 6.5% to 7.0%.
c.
For boilers specified to be less than
9ppm NOx adjust the O2 level within
7.0% to 9.0%.
Note: High Fire O
2
levels are adjusted with
the gas shutter valve located on the
outlet of the gas valve.
i.
Turn adjustment screw toward the
‘Plus (+)’ side to increase gas flow
(decrease O
2
level).
ii.
Turn adjustment screw toward the
‘Minus (-)’ side to decease gas flow
(increase O
2
level)
24.
Menu > Operation > High/Low > Low
> Back Arrow
(76 password required)
25.
Verify the O
2
level is /- 0.3% of
the O2 level set at high fire with all
jacket doors installed and front cabinet
door closed. (Consult the factory for
assistance if the O2 levels are not within
+/- 0.3% from high fire to low fire.)
