24) Verify primary control operation and safety features according to procedure outlined in the instructions furnished with
control.
25) Check pressure limit control operation. Jump thermostat terminals and allow burner to run until boiler pressure exceeds
cut-in pressure plus the differential. The burner should shut down.
26) Check low water cut-off operation. With the thermostat still jumped, fire the boiler and crack the boiler drain valve so that
water is slowly drained from the boiler. Confirm that the burner shuts down before the water level drops below the bottom of
the sight glass. 

Do not permit the boiler to fire without water visible in the sight glass

. Add water to the boiler and

confirm that the burner restarts. Remove thermostat jumper and reconnect thermostat upon check completion.
27) After the boiler has operated for approximately 30 minutes, check the boiler and heating system for leaks. Repair any
leaks found at once.
28) After the above checks have been completed, leave thermostat(s) at desired setting. Leave all instructions provided with
the boiler with owner or in boiler room, displayed near boiler.
29) After new boiler has been installed and put into continuous operation for several days, clean the boiler of oil, grease,
sludge, and other contaminants that may have been present in existing piping. This will prevent unsteady water line and water
carry over into supply main. The boiler boil-out should be done as follows:

a) Turn off the burner.
b) Drain water from boiler until about one inch of water is visible in gauge glass.
c) Run a hose or temporary piping from the boiler drain valve to a location where hot water can be safely discharged.

Drain approximately five gallons of water from the boiler and mix-in an appropriate amount of an approved boil-out
compound. Remove safety valve and refill the boiler with prepared solution through funnel. Replace safety valve.

d)    Run a hose or temporary piping from the 1-1/2” skimmer tap on the upper rear section to a location where hot water

can be safely discharged.

e) Start the burner. Run boiler for several hours, boiling the water, without generating steam pressure. Open the water

feed valve sufficiently to allow a slight overflow of water through the skimmer tapping drain line. Continue boiling
until water coming out is clear.

f)

Turn off the burner. Drain hot water from boiler through boiler drain valve to a location where hot water can be
safely discharged.  Refill the boiler to normal water line level. If water in the gauge glass does not look clear, repeat
above boil-out procedure again until water clears out.

g) Reinstall safety valve and related piping.
h) Conduct pH and Alkalinity test of water in the system. The pH reading should be in 7 to 11 range.

NOTE

When substantial amount of make-up water is used due to lost condensate, or when make-up water is hard or corrosive,
water treatment is required. Contact qualified water treatment company for recommended water treatment compounds
and procedure.

CAUTION

ATTEMPTS TO USE BURNERS OR BURNER CONFIGURATIONS OTHER THAN THOSE SHOWN IN
TABLE 3 COULD RESULT IN RELIABILITY PROBLEMS, DAMAGE TO THE BOILER NOT COVERED
UNDER WARRANTY, PROPERTY DAMAGE, OR UNSAFE OPERATION.
