‰
Verify that the boiler and system are full of water and all
‰
system components are correctly set for operation.

‰
Verify that there are no leaks in the system, DHW piping,
‰
connections or boiler.
Verify electrical connections are correct and securely at-
‰
tached.
Inspect vent piping and air piping for signs of deterioration
‰
from corrosion, physical damage or sagging. Verify air pip-
ing and vent piping are intact and correctly installed per this
manual.
Read the instructions to adjust and set up the FreeStyle
‰
control.
Verify that the boiler model is set correctly in the FreeStyle
‰

To start the boiler
The combustion for this boiler has been
checked, adjusted and preset at the factory
for operation for Natural Gas.
Having checked:
• That the boiler has been installed in accordance with
these instructions.
• The integrity of the flue system and the flue seals.
• The integrity of the boiler combustion circuit and the
relevant seals.
1. Apply power to the boiler.
2. Follow the Operating Instructions, Figure 105, page 80.
Test Mode Operation
Proceed to put the boiler into operation as follows:
1. To start create a demand for heat, open up a hot water
faucet(s) or turning up the thermostat. This way you will
ensure that during the "Test Mode" a heat load is created to
"Dump" the energy from the boiler.
2. To operate the boiler in test mode, press the CH "-" and
"+" keys together for 5 seconds (See below) to activate the
"TEST" mode.

3. The boiler lights at the maximum heating 100% rate displayed
on the LCD display.
4. The high fire (large) flame symbol will be displayed once the
boiler has lit.
5. Use DHW "-" button to drop firing rate to low fire.
6. To exit the "TEST" mode, press the CH keys (Items 3 and
4 Figure 80, page 62) together for 5 seconds, or leave the
boiler to automatically switch off after 15 minutes or stop-
ping DHW flow.
7. This TEST procedure is used to check/adjust combustion
CO and CO per specifications Figure 107, page 82 and
2
Figure 110, page 83.
If boiler does not start correctly
1. Check for loose connections, blown fuse or is boiler Not
®
plugged in?
2. Are external limit controls (if used) open? Is boiler water
®
temperature above 200°F?
3. Are thermostats set below room temperature?
4. Is gas turned on at meter and boiler?
5. Is incoming gas pressure less than the minimum values given
on page 14?
6. Are FreeStyle ® control settings correct for the application?
7. If none of the above corrects the problem, refer to Trouble-
shooting, beginning on page 89.
Check system and boiler
‰
‰
Check water piping
1. Check system piping for leaks. If found, shut down boiler and
repair immediately. (See WARNING on page 76 regarding
failure to repair leaks.)
2. Vent any remaining air from system using manual vents. Air
in the system will interfere with circulation and cause heat
distribution problems and noise.
‰
Check vent piping and air piping
1. Check for gas-tight seal at every connection and seam of air
piping and vent piping.
Venting system must be sealed gas-tight to prevent
flue gas spillage and carbon monoxide emissions
which will result in severe personal injury or death.
‰
Check gas piping
1. Check around the boiler and inside the boiler jacket for gas
odor following the instructions in "Warning"on page 50 of
this manual.
If you discover evidence of any gas leak, shut
down the boiler at once. Find the leak source
with bubble test and repair immediately. Do
not start boiler again until corrected. Failure
to comply could result in severe personal in-
jury, death or substantial property damage.
