system components are correctly set for operation.

Verify that condensate trap drain line is lled with water.

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

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:
• at the boiler has been installed in accordance with
these instructions.
• e integrity of the ue system and the ue seals.
• e 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. is 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.
Figure 104 Control in Test Mode
3. e boiler lights at the maximum heating 100% rate displayed
on the LCD display.
4. e high re (large) ame symbol will be displayed once the
boiler has lit.
5. Use DHW “-” button to drop ring rate to low re.
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 o aer 15 minutes or stop-
ping DHW ow.
7. is TEST procedure is used to check/adjust combustion

per specications Figure107, page82 and
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
ue 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.
