Start-Up Procedures
SECTION XI - Start-Up Procedures
Final Checks Before Start-Up
c
Read page 37 through 52 regarding the
operation of the Trimax Boiler
Management System.
c
Verify the PRESTIGE Excellence and the
boiler system are full of water and all sys-
tem components are correctly set for oper-
ation, including the minimum flow rate
through the boiler, see page 81.
c
Verify Start-up Preparation items outlined on
pages 53 thru 55 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 PRES-
TIGE Vent Supplement.
c
Verify burner configuration - Propane only.
- Check for proper labeling on the gas
valve and the rating label for propane
configuration.
- If there is doubt on the burner configura-
tion, remove the gas valve and check for
proper propane gas orifice size: 0.204”
(5.2 mm). Refer to Fig. 16, page 27 for
location of the propane gas orifice.
c
Ensure the vent Condensate Drain
Assembly is filled with water.
PRESTIGE Excellence Start-Up
1. Press the ON-OFF button located on the
front control panel to the OFF position. Turn
ON the electrical supply/service to the unit.
2. Read and follow the Operating Instructions
outlined on page 60.
If PRESTIGE Excellence Does Not Start
Correctly
1. Check for loose electrical connections,
blown fuses, (on control module and in ter-
minals) or an open service switch.
2. Verify CH and DHW operation is enabled.
A radiator or faucet icon with an X through
it indicates that function is disabled.
3. Check continuity across the LWCO device
for a closed circuit. See item 6 on Fig. 34,
page 74.
4. Is an external limit control (if applicable)
open? Ensure the external limit is reset to
the closed position.
5. Are the gas supply valves open at the unit
and meter?
6. Is incoming gas supply pressure at the unit
more than 5”w.c. and less than 13” w.c. for
natural or propane with all gas appliances
ON or OFF.
7. Are the heating thermostats set above room
temperature?
If none of these conditions correct the problem,
refer to the PRESTIGE Excellence Trouble-
Shooting Guide or contact ACV-Triangle Tube
Technical Support.
Check the PRESTIGE Excellence and System
c
Check Boiler Piping.
Check Boiler system piping and com-
ponents for leaks. If found, shut down
the unit 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.
