VIII. System Start-up
A.
Safe operation and other performance criteria were met
with the 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.
Check Main Burners. Main burners must be properly
located on support bracket in Base Rear Panel, seated
on Main Burner Orifices, and secured with hitch pin
clips.
C.
Verify that the venting, water piping, gas piping and
electrical system are installed properly. Refer to
installation instructions contained in this manual.
D.
Confirm all electrical, water and gas supplies are
turned off at the source and that vent is clear of
obstructions.
E.
FILL ENTIRE HEATING SYSTEM WITH WATER
and vent air from system. Use following procedure on a
Series Loop or multi-zoned system installed as per
Figure 25 to remove air from system when filling.
At completion, open all zone valves or shut-off
valves.
9. Close purge valve, continue filling the system until
the pressure gauge reads the desired cold fill
pressure. Close fill valve.
(Note - If make-up water line is equipped with
pressure reducing valve, adjust pressure reducing
valve to desired cold fill pressure. Follow fill valve
manufacturer’s instructions).
10. Open isolation valve in boiler supply piping.
11. Remove hose from purge valve.
F.
Confirm that the boiler and system have no water leaks.
G.
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.
4. Turn on gas supply to the boiler gas piping.
5. Confirm that the supply pressure to the gas valve is
14 in. w.c. or less.
6. Open the field installed manual gas shut-off valve
located upstream of the gas valve on the boiler.
7. Using soap solution, or similar non-combustible
solution, electronic leak detector or other approved
method. Check that boiler gas piping, valves, and
all other components are leak free. Eliminate any
leaks.
8. Purge gas line of air.
Table 11: Lighting and Operating Instructions
1. Close full port ball valve in boiler supply piping.
2. Isolate all zones by closing zone valves or shut-off
valves in supply and return of each zone(s).
3. Attach a hose to the vertical purge valve located
prior to the full port ball valve in the system supply
piping. (Note - Terminate hose in five gallon
bucket at a suitable floor drain or outdoor area).
4. Starting with one circuit at a time, open zone valve
or shut-off valve in system supply and return
piping.
5. Open purge valve.
6. Open fill valve (Make-up water line should be
located directly after full port ball valve in system
supply piping between air scoop and expansion
tank).
7. Allow water to overflow from bucket until
discharge from hose is bubble free for 30 seconds.
8. Close the open zone valve or shut-off valve for the
zone being purged of air, then open the zone valve
or shut-off valve for the next zone to be purged.
Repeat this step until all zones have been purged.
H.
Follow Lighting or Operating Instructions to place boiler
in operation. Refer to label on inside of Front Removable
Panel or appropriate Figure as listed in Table 11.
