9 Start-up
Final checks before starting the boiler
Read the Crest Service Manual to familiarize yourself with SMART TOUCH control module operation. Read this manual, page 43 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 40 and 41 have been completed.
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.
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 the boiler receiving a call for heat?
4.Is gas turned on at meter and 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 Crest 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 40 and 41 (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.
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 31 of this manual (connecting gas supply piping).
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.
Check flame and combustion
