3. Boilers that have a vent damper are factory wired with
a male plug.
i) Attach the flexible metallic conduit vent damper har-
ness to the right hand side of the jacket by passing
the free end of the harness through the 22 mm (
diameter hole in the top of the jacket, and using the
BX connector at the free end of the metallic conduit,
fasten to jacket.
ii) Connect "FEMALE PLUG" (free end of vent damper
harness) into "MALE PLUG" (see correct wiring
diagram for both continuous and intermittent pilots).
iii) The other end of the flexible metal conduit has a
small molex plug and a 90 degree metal conduit
connector. Route the molex receptacle through the
conduit bracket on the vent damper. Place the har-
ness receptacle into the damper plug. Securely fas-
ten the harness conduit connector to the conduit
bracket by carefully pushing it into the hold in the
bracket.
4. All Slant/Fin Galaxy steam boilers equipped with inter-
mittent pilot ignition and continuous (standing) pilot
systems are factory wired except for the wires to the
low water cut-off and pressure cut-off. Wire these con-
trols with wire provided with boiler (see boiler wiring
diagram on boiler). Then follow previous instructions
shown in #4 above.
5. Restore electrical power and turn on gas supply.
E.AFTER INSTALLATION:
1. Operate system through two complete cycles to check
for opening and closing in proper sequence, and prop-
er burner operation. DAMPER MUST BE IN OPEN
POSITION WHEN BOILER MAIN BURNERS ARE
OPERATING.
2. Perform installation checks as required by ANSI speci-
fication Z21.66 or CSA B149.1-00 for natural gas and
propane.
3. Replace the front cover of the boiler.
4. Check the troubleshooting section if problems arise
with the installation.
THERMOSTAT HEAT ANTICIPATOR ADJUSTMENTS
If the 24V room thermostat that controls the boiler has an adjust-
ment heat anticipator, it must be set to the AMP draw of the boil-
er. Connect the system to the thermostat and run the system.

OPERATING INSTRUCTIONS, BASIC
A. Before firing boiler, make these checks:
1. Relief valve is installed. Installation of the relief valve shall
be consistent with the ANSI/ASME Boiler Pressure Vessel
Code. Valve opening is NOT closed or reduced in size.
2. Draft hood is installed and vented to chimney.
3. All wiring is completed, following applicable wiring dia-
grams.
4. If a vent damper is added, damper is in full open posi-
tion. See instructions furnished with vent damper.
5. Using soap solution, check for gas leaks in all gas piping
from meter to boiler pilot and manifold. DO NOT use
open flame.
pp6. System is filled with water and vented.

FILLING AND VENTING WATER SYSTEMS

A. Fill the system with water. Vent or purge off air.
B. Fire the boiler as soon as possible (see following warning
and instructions) and bring water temperature to at least
82°C (180°F), while circulating water in the system.
C. Vent air and add water as needed to achieve operating
pressure on boiler gauge. Pressure must be between
approximately 83 kPa (12 psi) (cold water) and 172 kPa (25
psi) (at water temperature setting of high limit control), for
boilers equipped with 207 kPa (30 psi) relief valves. Boilers
rated for a higher pressure and equipped with a matching
relief valve may operate at a higher pressure, but no higher
than 34 kPa (5 psi) below the relief valve opening pressure.
D. Check for and repair any leaks before placing system in ser-
vice. Make sure that none of the automatic gas ignition sys-
tem components are exposed to water.
CLEANING AND FILLING A NEW STEAM BOILER
Before using steam boiler:
A. Check boiler to be certain it is ready for firing. DO NOT FIRE
into an empty boiler.
B. Be prepared to heat raw water to at least 82°C (180°F) as
soon as it is introduced into the boiler. This procedure will
remove dissolved, corrosive gases.
C. Provide drain line, with valve, from boiler. Use a bottom tap-
ping. Line and drain must be suitable for handling caustic
solution.
