FUEL SUPPLY
1. Fuel gas piping must be in accordance with
National Fuel Gas Code, ANSI Z223.1/NFPA
31/NFPA 54 latest revision and applicable
provisions of local building codes.
2. The Dynatherm™ boiler is listed by the
Underwriters Laboratories to burn the
following gases:
Number 2 fuel oil.
Propane, in accordance with national
regulations, with a content of elementary
Sulphur less than 1.5 ppm and volatile
Sulphur less than 50 ppm.
Natural gas from the public gas supply, in
accordance with national regulations,
with a total Sulphur content less than
15ppm.
Since fuel grades marketed by different
distributors may vary, it is advantageous for you
to be familiar with the quality of fuels available
in your area.
3. Before installing and connecting any fuel
lines, turn off the main fuel supply. If there is
no shutoff valve, install a valve between the
fuel tank and fuel pump in accordance with
local codes.
4. Install a ground joint union for servicing, if
required.
5. Connect the suction line from the fuel tank to
the pump using an unbroken length of copper
tubing and flare type fittings as required by
the burner manufacturer.
6. In cases where there is an underground or
remote fuel tank, it is recommended to use a
Suntec Model A1VD-7741 Pump and 1/6 HP
motor to maintain proper fuel delivery.
7. If using No. 2 fuel oil, an external,
appropriately listed and certified fuel filter
must be placed in the fuel line between the
fuel tank and the burner pump.
A Gar-Ber fuel oil filter is recommended.
8. Ensure that all air is out of the fuel lines.
Whenever any line in the system is opened,
air must be bled from the high points of the
system. The boiler should always be double
checked for air.
9. Turn on the main fuel supply/shutoff valve
and check for any leaks using an approved
combustible gas detector, soap and water, or
similar nonflammable solution.
Do not use matches, candles, flames or any
ignition source to check for leaks.
ELECTRICAL WIRING
1. All electrical equipment and wiring must be
installed in accordance with the National
Electric Code, ANSI/NFPA-70 latest revision
and applicable provisions of the local building
codes.
2. Wiring is to be done inside BX cable or
conduit.
3. All connections must be soldered or approved
connectors. The minimum wire gauge
conductor size should be #14.
4. Since the Dynatherm™ boiler is supported by
numerous burners and controls, please refer
to the wiring diagrams in those manuals for
proper wiring.
INITIAL BURNER SETUP & START-UP
1. Refer to the burner installation manual
provided with your burner for proper setup &
start-up procedures.
2. Use the proper instruments to adjust the
burner settings to achieve 11% - 13% CO
2
readings and a smoke reading of zero.
Variations in flue gas, smoke, CO
2
and
temperature readings may be experienced
when the burner cover is put in place.
Therefore, the burner cover must be in place
when making the final combustion instrument
readings to ensure proper test results.
