SANITARY HOT WATER HEATING COIL
Before attempting to install a coil, always check the water quality to
avoid premature scaling, which quickly renders your installation
inefficient. Consult a specialist and have a water treatment system
installed, if necessary.
Locate the water inlet with the marking "IN". We strongly
recommend the use of a thermostatic mixing valve to achieve safe
and optimal operation from the installation.
We recommend that a qualified service
technician start-up and service your boiler.
Ensure that the boiler and the system are
always full of water and that all air has been
bled before starting the burner.
2.1)
FUEL
Use only No. 2 fuel oil. Never attempt to use a heavier fuel oil,
gasoline, motor oil or any other sort of fuel with your boiler.
2.2)
START UP
1.
Make sure that the tank contains fuel oil and that the fuel and
water valves are open;
2.
The main power switch must be "OFF";
3.
Set the Limit Control to the desired temperature, for example
o
o
82
C (180
F);
4.
Install a 0 - 1400 kPa (200 psi) pressure gage on the oil pump.
The use of a suction gage may also be appropriate at the oil
pump inlet, if suction of over 20.7 kPa (3 psi) may be
encountered;
5.
Pre-adjust the burner according to the specifications of Tables 2,
3 or 4, p. 9 and 10. These specifications should only be used as
a reference for initial start-up. Refer to the manual provided with
the burner for further information on adjustments;
6.
Turn the main switch "ON" and start the burner by setting the
thermostat to its maximum;
7.
Air can be bled from oil lines through the bleed port on the oil
pump. If there is no ignition and the burner combustion relay
goes into safety mode, see Section 2.3 below;
8.
Adjust the oil pressure to the specified value in Tables 2, 3 or 4,
p. 9 and 10;
9.
Adjust the chimney draft as specified in Table 1, p. 4. Take this
reading midway between the draft regulator and the outlet of the
boiler;
10. Adjust the burner air band(s) for a smoke scale reading of 0 on
the Bacharach scale;
11. Analyse the combustion gases with an appropriate instrument
and set the burner accordingly.

THERMOSTAT
The thermostat must be mounted on an inside wall, approximately
1.5 m (5') above the floor. The location should be such that the
thermostat is not subjected to air currants and/or exposed to direct
sunlight.
1.15)
DRAFT REGULATOR
For chimney venting, a barometric draft regulator must be installed
on the connecting pipe between the chimney and the boiler. It must
be located in an easily serviceable location. Please refer to the
installation instructions supplied with it.
PART 2
OPERATION
Note: If a burner cabinet is used, ensure that all tests
are done with this cabinet in place. Do not
forget to tighten the adjustment screws once
the burner is adjusted, before putting the burner
cabinet back permanently.
12. Check the correct operation of the temperature controls and the
burner combustion relay;
13. Adjust the limits and the thermostat to the desired set points. Be
sure to avoid operating settings which will result in the boiler
water temperature going below 60°C (140°F).
2.3)
RESTARTING AFTER IGNITION FAILURE
1.
Check the oil level in the fuel tank;
2.
Make sure the fuel supply valve is open;
3.
Make sure the oil filter is not clogged;
4.
Check the electrical circuit (fuse or breaker);
5.
Check the burner electrode settings. Refer to the burner
instruction manual;
6.
Check if the thermostat is calling for heat;
7.
Check for air in the oil pump suction line.
If after following these steps and pressing the red Burner Reset
Button, the burner still does not fire, call a qualified service technician.
Never attempt to re-start the burner if excess fuel oil or fumes have
accumulated in the combustion chamber.
2.4)
SUMMER SEASON
Make sure the fuel oil valve is closed when the boiler is not in use for a
long period of time.
2.5)
START-UP AT THE BEGINNING OF THE
HEATING SEASON
1.
Clean the chimney, the connecting flue pipes and the boiler.
Follow the steps in Section 3.6);
2.
Replace the oil filter;
3.
Have the burner electrodes cleaned along with the burner
retention head and change the nozzle;
4.
Check the operation of the high temperature Limit Control;
5.
Check the operation of the circulating pump.
