GOLD CGi Gas-Fired Water Boiler — Boiler Manual

Fill the system with water

1.  Close manual and automatic

and boiler drain cock.

.

Correct pressure will vary with each

application. Typical cold water fill pressure for a residential system is
1 psi.

3.

from system:

a.  Connect a hose to the purge valve (see

drain valves, item

, in

suggested piping diagrams on pages 3 through ,

through

). Route hose to an area where water can drain

and be seen.

b.  Close the boiler or system isolation valve between the purge valve

and fill connection to the system.

c.  Close zone isolation valves.
d.  Open quick-fill valve on cold water makeup line.
e.  Open purge valve.
f.  One zone at a time, open the isolation valves. Allow water to run

through the zone, pushing out the air. Run until no noticeable air
flow is present. Close the zone isolation valves and proceed with
the next zone. Follow this procedure until all zones are purged.

g.  Close the quick-fill water valve and purge valve and remove the

hose. Open all isolation valves. Watch that system pressure rises to
correct cold-fill pressure.

h.  After the system has operated for a while, eliminate any residual

air by using the manual air vents located throughout the system.

i.  If purge valves are not installed in system, open manual air vents

in system one at a time, beginning with lowest floor. Close vent

when water squirts out. Repeat with remaining vents.

4.  Open

(diaphragm-type or bladder-type expansion

tank systems only) one turn.

5.  Open other vents:

a.  Starting on the lowest floor, open air vents one at a time until

water squirts out.

b.  Repeat with remaining vents.

6.  Refill to correct pressure.

Inspect system water piping

After filling the boiler and system with water,

throughout the system for leaks. If found, repair

immediately. Repeat this inspection after the boiler has
been started and the system has heated up.

Failure  to  do  so  can  damage  the
boiler, resulting in substantial prop-
erty damage.

Do  not  use

in boiler system. Severe damage to
boiler will occur, resulting in sub-
stantial property damage.

Inspect base insulation

The  boiler  contains  ceramic  fiber
and  fiberglass  materials.  Use  care
when handling these materials per
instructions  on

 of  this

manual.  Failure  to  comply  could
result in severe personal injury.

damaged insu-

lation or reposition insulation can
result in a fire hazard, causing severe
personal injury, death or substantial
property damage.

Check to make sure

against

all four sides of the base. If insulation is damaged or
displaced,

operate boiler. Replace or reposition

insulation.
