Start-up
Final checks before starting the boiler
 Read the SYNC Service Manual to familiarize yourself
with SMART TOUCH control module operation. Read
this manual, page 46 for proper steps to start boiler.
 Verify the boiler and system are full of water and all
system components are correctly set for operation.
 Verify the preparation procedures of Section 9, pages 43
and 44 have been completed.
 Fill the vent condensate trap with water (removing the
retaining screw in order to remove the 2 inch (50.8 mm)
PVC cap with the switch located at the top of the trap).
Replace the cap. Press the cap onto the trap until the
cap makes contact with the drain. Replace the retaining
screw.
 Verify electrical connections are correct and securely
attached.
 Inspect vent piping and air piping for signs of deterioration
from corrosion, physical damage or sagging. Verify air
piping and vent piping are intact and correctly installed
per this manual.

Start the boiler

1. Read and follow the Operating instructions in FIG. 9-2,
page 46.
If boiler does not start correctly
1. Check for loose connections, blown fuse or service switch
off?
2. Is external limit control (if used) open? Is boiler water
temperature above 200°F (93°C)?
3. Is thermostat set below room temperature?
4. Is gas turned on at meter or boiler?
5. Is incoming gas pressure less than 4 inches w.c. (.99 kPa)?
If none of the above corrects the problem, refer to the
Troubleshooting Section of the SYNC Service Manual.
Check system and boiler
 Check water piping
1. Check system piping for leaks. If found, shut down
the boiler and repair immediately. (See WARNINGS
on pages 43 and 44 (startup) regarding failure to repair
leaks.)
2. Vent any remaining air from the system using manual
vents. Air in the system will interfere with circulation
and cause heat distribution problems and noise.

Installation & Operation Manual
 Check vent piping and air piping
1. Check for gastight seal at every connection, seam of air
piping, and vent piping.
Venting system must be sealed gastight
WARNING
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 for gas odor following the
procedure on page 34 of this manual (connecting gas
supply piping).
If you discover evidence of any gas leak,
WARNING
shut down the boiler at once. Find the
leak source with a bubble test and repair
immediately. Do not start the boiler again
until corrected. Failure to comply could
result in severe personal injury, death, or
substantial property damage.
Check flame and combustion
1. Turn the main power off to the boiler by placing the
"On/Off" switch in the OFF position.
2. Remove the flue temperature sensors from the flue pipe
connections. Note: Combustion measurements will be
made at this point.
3. Turn the main power on to the boiler by placing the
"On/Off" switch in the ON position.
