Finalizing The Installation; Initial Start-Up Procedures - Central Boiler CLASSIC Owner's Manual

FINALIZING THE INSTALLATION

Before firing the furnace for the first time,
perform the following important items:
A. Check for leaks. Pressure test the entire plumbing
system. Apply 30 lb of pressure for thirty minutes
and closely monitor for any pressure loss. Inspect all
fittings and hose ends for any signs of leakage; repair
as necessary. A very slow leak at a hose clamp may
possibly be stopped by tightening the clamp after the
system has warmed up as the poly becomes more
pliable when it is warm. It also may be necessary to
install a second hose clamp with the screw positioned
on the opposite side of the hose. Release the pressure
upon completion of the test.
NOTE: PEX lines should never be pressurized
when the heating system is being operated.
B. Cover Water Lines. Backfill the trench dug for the
installation of the water lines. If the water lines are
to be run on top of the ground, cover the lines as they
will deteriorate with exposure to UV rays.
C. Remove the strapping securing the vent cap. The
vent cap must fit loosely over the furnace vent.
D. Fill with water, purge air from the system, and
verify flow direction of the water. All air must be
purged from the water lines when filling the system.
The water must circulate in the hot supply line from
the furnace to the building being heated. Also, the
circulation pump(s) must be installed in the hot
supply line(s). See Initial Start-up Procedures section
for details.

E. Add Corrosion Inhibitor. Add Corrosion Inhibitor
immediately after filling with water. Be sure to add
Corrosion Inhibitor as soon as possible so it will
immediately begin to protect the steel. Bring the water
temperature to the operating temperature as soon as
possible after adding the Corrosion Inhibitor. It
should not be necessary to add water to the furnace
frequently. If water needs to be added more
frequently than once every six months, either there
is a leak in the system or the furnace is boiling because
of improper operation or maintenance (see
Troubleshooting Section B). Be sure to locate and
repair the problem immediately. The need to
frequently add water will cause deterioration in the
water jacket. Corrosion Inhibitor must be added if
water is added to the furnace. Deterioration due to
improper operation and/or maintenance is not covered
by warranty.

INITIAL START-UP PROCEDURES

NOTE: Be sure to fill the furnace with water of good
quality. See Water Quality and Maintenance section
of this manual.
Use the following procedure to fill the outdoor furnace
with water and purge the air from the system. Be sure to
purge the air from each pump circuit from the outdoor
furnace. If the furnace is being filled with water when the
outdoor temperature is very cold, be sure the water is
circulated immediately after filling to prevent freezing of
the water lines beneath the furnace. If the water heater has
been in use, flush the water heater to remove all sediment
prior to filling the outdoor wood furnace with water.
