Start-Up Procedures
SECTION XI - Start-Up Procedures
Final Checks Before Start-Up
c Read page 46 through 57 regarding the
operation of the CHALLENGER control.
c Verify the CHALLENGER and the boiler
system are full of water and all system
components are correctly set for operation,
including the minimum flow rate through
the boiler, see pages 80-82.
c Verify Start-up Preparation items outlined on
pages 40 thru 42 have been completed.
c Verify all electrical connections are correct
and securely fastened.
c Inspect vent and combustion air piping for
signs of deterioration from corrosion, physical
damage or sagging. Verify combustion air
and vent piping are intact and correctly
installed and supported. Reference the proper
CHALLENGER vent supplement.
c Verify burner configuration - gas orifice
size.
- Check for proper labeling on the gas
valve (propane only) and the rating label
for proper gas configuration.
- If there is doubt on the burner configura-
tion, remove the gas valve and check for
proper gas orifice size. See pages 31 and
32 for orifice sizes.
c Ensure the vent Condensate Drain
Assembly is filled with water.
CHALLENGER Start-Up
1. Turn ON the electrical supply/service to the
appliance. Press the ON-OFF button “ ”
located on the front control panel to the OFF
position.
2. Read and follow the Operating Instructions
outlined on page 45.
If CHALLENGER Does Not Start Correctly
1. Verify DHW and CH systems are turned
ON (parameter 1) is set to “0”. Read set-
ting the appliance parameters section of the
manual starting on page 52 for more infor-
mation.
2. Check for loose electrical connections,
blown fuse (external or internal at the
appliance control) or open service switch.
3. Is the external limit control (if applicable)
open? Ensure the external limit is reset to
the closed position.
4. Is the gas supply valve(s) open at the appli-
ance and meter?
5. Is incoming gas supply pressure at the
appliance more than 5”w.c. [13 mbar] and
less than 13” w.c. [32 mbar] for natural or
propane with all gas appliances ON or
OFF.
6. Are the heating thermostats set above room
temperature?
If none of these conditions correct the problem,
contact Triangle Tube Tech Service.
Check the CHALLENGER and System
c Check Piping.
Check piping and components for
leaks. If found, shut down the appli-
ance and repair immediately.
Purge any remaining air from the system
piping. Air in the system piping will
interfere with circulation creating heat
distribution problems and system noise.
c Check Vent Piping and Combustion Air
Piping.
Check for gas-tight seal at every con-
nection and seam of the venting and
combustion air piping.
Venting system must be sealed gas-tight
to prevent flue gas spillage and potential
carbon monoxide emissions, which will
result in severe personal injury or death.
