9 Start-up(continued)

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).

Installation & Operation Manual

Check vent piping and air piping

1.Check for gastight seal at every connection, seam of air piping, and vent piping.

￿WARNING 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).

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

￿WARNING

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.

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 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.
