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.

 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
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,
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.
