VIII. System Start-up
A.
Safe operation and other performance criteria were
met with gas manifold and control assembly provided
on boiler when boiler underwent tests specified in
American National Standard for Gas-Fired Low-
Pressure Steam and Hot Water Boilers, ANSI Z21.13.
B
.
FILL ENTIRE HEATING SYSTEM WITH WATER
and vent air from system. Use the following procedure
on a Series Loop System equipped with zone valves.
(See Figure 4).
1. Close isolation valve in boiler supply piping.
2. Isolate all circuits by closing zone valves or
balancing valves.
3. Attach a hose to hose bib located just below
isolation valve in boiler supply piping. (Note -
Terminate hose in five gallon bucket or at a suitable
floor drain or outdoor area).
4. Starting with one circuit, open zone valve.
5. Open hose bib.
6. Open manual fill valve (Make-up water line should
be located directly above isolation valve in boiler
supply piping).
7. Allow water to overflow from bucket until discharge
from hose is bubble free for 30 seconds.
8. Open zone valve to the second zone to be purged,
then close the first. Repeat this step until all zones
have been purged, but always have one zone open.
At completion, open all zone valves.
9. Close hose bib, continue filling the system until the
pressure gauge reads between 12 and 15 psi. Close
fill valve.
WARNING
DO NOT install an automatic fill valve with this
boiler.
10. Open isolation valve in boiler supply piping.
11. Remove hose from hose bib.
C.
Prepare to check operation.
1. Obtain gas heating value (in BTU per cubic foot)
from gas supplier.
2. Connect manometer to pressure tap on gas valve.
Use 1/8 NPT tapping provided.
3. Temporarily turn off all other gas-fired appliances.
D.
Operating Instructions
1. Follow Operating Instructions to place boiler in
operation. See Figure 21.
2. Electronic Ignition Modules with LED indicators.
Table 8 cross-references the ignition module
terminal designations to the ignition terminal
numbers in the wiring ladder diagrams. The yellow
LED indicates the status of the flame, see Table 9.
The green LED indicates the status of the system,
see Table 10. See Figure 22 for LED locations. See
Figure 23 for Troubleshooting Guide.
