A. VERIFY that the venting, water piping, oil piping,
and electrical system are installed properly. Refer to
installation instructions contained in this manual.
B.
CONFIRM all electrical, water and oil supplies are
turned off at the source and that the vent is clear from
obstructions.
Completely read, understand and follow all

CHECK CONTROLS, WIRING AND BURNER
to be sure that all connections are tight and burner is
rigid. Verify that all electrical connections have been
completed, fuses installed, that the oil tank is filled and
oil lines have been tested.
LUBRICATION. Follow instruction on burner and
circulator label to lubricate, ifoil lubricated. Most
motors currently used on residential type burners
employ permanently lubricated bearings and thus do
not require any field lubrication. Water lubricated
circulators do not need field lubrication.
ADJUST CONTROL SETTINGS with burner
service switch turned "ON" and room thermostat set
and vent air from system.
steps below:
1.
See Figures 5 & 6 and follow
Close isolation valve in boiler supply piping.
2. Isolate all circuits by closing zone valves or
balancing valves.
3. Attach a hose to hose bib located just before
isolation valve in boiler supply piping. See Figures
5 and 6. (Note - Terminate hose at a suitable floor
drain or outdoor area).
4. Starting with one circuit at a time, open zone valve
or valve.
5. Open hose bib.
6. Open fill valve (Make-up water line should be
located directly after isolation valve in boiler supply
piping between air scoop and expansion tank).
7. Allow water to flow into drain until discharge from
hose is bubble free for 30 seconds.
8.
When zone is completely purged of air, close zone
valve or balancing valve. Open the zone valve for
the next zone to be purged. Repeat this step until
all zones have been purged. At completion, open all
zone valves or valves.
10° below room temperature.
1. Adjustment and display modes of the L7248/
L7224 Oil Electronic Aquastat Controller.
a. On the L7248/L7224, the overall range of the
High Limit is from 180°F to 240°F (82°C to
116°C).
b. Set the High Limit (designated HL) on the
L7248/L7224 Aquastat Control at 180°F. This
temperature setting may be varied to suit
requirements of installation. Differential is fixed
at 15°F.
Adjusting Settings:
To discourage unauthorized changing of
Aquastat settings, a procedure to enter the
adjustment mode is required. To enter the
adjustment mode, press the UP, DOWN,
and I buttons (see Figure S1) simultaneously
for three (3) seconds. Press the T button
until the feature requiring adjustment is
displayed (press the 'T' button again and
will display LL (Low Limit on L7224):
• High Limit
• °F -- °C (Toggle)
The maximum operating pressure of this
boiler is 30 psig. Never exceed this pressure.
Do not plug or change pressure relief valve.
9. Close hose bib, continue filling the system until the
pressure gauge reads 12 psig. Close fill valve.
(Note - If make-up water line is equipped with
pressure reducing valve, system will automatically
fill to 12 psig.
10. Open isolation valve in boiler supply piping.
11. Remove hose from hose bib.
CONFIRM that the boiler and system have no water
leaks.
