Instructing the system user
The installer of the system is
responsible to ensure the system
operator/ultimate owner is made
familiar with the system functioning, its
activation, its shut-down, and the need
for periodic service.
Initial start-up
Initial start-up must be performed by a

calibrations specified in the burner test
sheet are to be verified at this time.
Completion of the Maintenance Record
by the heating contractor is also
required.
The following topics must be covered:
Proper system operation sequence.
Explain the equipment as well as the
need for combustion air.
Demonstrate an emergency
shut-down, what to do and what not.
Explain that there is no substitute for
proper maintenance to help ensure
safe operation.
Working on the equipment
The installation, adjustment, service,
and maintenance of this boiler must be
done by a licensed professional heating
contractor who is qualified and
experienced in the installation, service,
and maintenance of hot water boilers.
There are no user serviceable parts on
the boiler, burner, or control.
Ensure main power supply to
equipment, the heating system, and all
external controls has been deactivated.
Close main oil or gas supply valve. Take
precautions in both instances to avoid
accidental activation of power during
service work.
Please carefully read this manual prior
to attempting start-up, maintenance
or service. Any warranty is null and
void if these instructions are not
followed.

Operating Instructions, Service Instructions of Burner
1. Ensure fresh air intake of boiler room
is open and that chimney and all flue
pipes are connected, sealed and
unobstructed inside.
2. Ensure proper operation of expansion
tank (see Maintenance/Service
manual).
3. Fill heating system with water and
bleed out air completely. Ensure
complete system is properly vented
of air.

.....................................
Max. testing pressure
68 psig / 465 kPa
.....................................
Max. boiler temperature
248°F / 120°C
.........................................
4. Perform a pressure test of the boiler
and the water piping. Pressure test
must not exceed 1½ times the
maximum operating pressure (45 psi)
of the boiler. Pressure relief valve
must be removed during pressure
test. Any leaks must be corrected.
5. Ensure proper and adequate fuel
supply exists; open oil shut-off valve.
6. Verify completeness of all discussion
points on the following pages in the
section entitled Service before
starting-up system.
If the nitrogen pressure of the
precharged expansion tank is less
than the static pressure of the
system, inflate membrane pressure to
slightly exceed pressure of system.
The static pressure required at the
tank is based upon the static height
of the system.
Water treatment should be considered
in areas where it is known that boiler
feed water contains a high mineral
content and hardness.
In areas where freezing might occur,
an antifreeze may be added to the
system water to protect the system.
Please adhere to the specifications
given by the antifreeze manufacturer.
Do not use automotive silicate-based
antifreeze. Ensure a copy of the
Material Safety Data Sheet is left on
site.
Please observe that an
antifreeze/water mixture may require
a backflow preventer within the
automatic water feed and influence
components such as diaphragm
expansion tanks, radiation, etc. A
40% antifreeze content will provide
freeze-up protection to -10°F / -23°C.
Do not use antifreeze other than
specifically made for hot water
heating systems. System also may
contain components which might be
negatively affected by antifreeze.
Check total system frequently when
filled with antifreeze.

tanks, low water cut-offs, pumps, etc.
Flush float water type low water
cut-offs (if used).
The usual water fill pressure is between
10 and 15 psi with the system cold. A
lower pressure gage reading usually
indicates loss of water due to leakage.
All leaks must be corrected. Refer to
instructions packaged with automatic
fill valve. Follow local regulations with
respect to backflow preventers.
If oil-lubricated pumps are used, ensure
proper lubrication.
If motorized zone valves are used, refer
to maintenance instructions provided
