Start-Up Procedures
SECTION XI - Start-Up Procedures
Final Checks Before Start-up
Verify the ELITE and the primary and
domestic systems are full of water and
all system components are correctly set
for operation.
Verify Start-up Preparation items outlined
on pages 37 thru 39 have been completed.
Verify all electrical connections are
correct and securely fasten.
Inspect vent piping and combustion air
inlet piping for signs of deterioration from
corrosion, physical damage or sagging.
Verify combustion air piping and vent pip-
ing are intact and correctly installed.
Adjustment of the Secondary Thermostat
Limit.
The Secondary (Domestic) Thermostat
located on left side of the control panel
maintains the minimum domestic water
storage temperature.
Set the thermostat knob as shown in
Fig. 22 page 42.
Maximum limit setting is 140ºF
ELITE Start-up
Turn the ON-OFF switch located on the
front control panel to the OFF position.
Turn the electrical supply or any service
switch to the unit in the ON position.
Check Domestic Piping.
Check domestic piping and system
components for leaks. If found, shut
down the unit and repair immediately.
Check Primary Piping.
Check primary 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.
Check Vent Piping
Check for gas-tight seal at every connec-
tion and seam of the venting.
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.
Check Gas Piping (if applicable)
1. Check around the unit for gas odor fol-
lowing the procedure outlined in this
manual on Page 39.
If any gas leaks are found or suspected,
shut the unit down immediately. Use a
gas detection device or bubble test to
locate the source of the gas leak and
repair at once. Do not operate the unit
until the leak is corrected. Failure to
comply with this procedure could result
in severe personal injury, death or sub-
stantial property damage.
Check Oil piping (if applicable)
Check for any leakage at the pump and
all fittings
Verify Flame Pattern and Combustion
Check the flame pattern through the
inspection port of the burner. The
flame should be stable.
Test for CO2 or O2 and for CO. The
combustion reading should be within
the range listed in Table 2 page 41. The
CO level should not exceed 100 ppm
when combustion is correct.
