Eclipse PulsePak Valve Train Segments, V1, Installation Guide 791-2, 8/10/2010
Adjustment, Start &
Stop
Before Applying Gas
Before applying the site gas supply, be sure the actual
pressure does not exceed the inlet rating of the system.
Close the zone inlet valve and outlet manual valve on the
PulsePak valve train segment and then slowly open the
site gas supply valve.
Ŷ
Check for any abnormal conditions and
immediately shut off the site gas supply to the
system if you sense any danger such as gas leaks
or mechanical stress.
Tests
Leak Testing
The valve train segment is tested and leak tight at the
factory, however, shipping and installation may cause
joints to loosen. Check and test all piping for leaks.
Ŷ
Test pressure must not exceed 7 PSIG or 500 mbar
and any components with ratings less than the test
pressure should first be isolated. Check the
individual product datasheets for specific ratings.
Shutoff Valve Functional Test
1.
Slowly open the zone manual valve to allow gas to
flow to the PulsePak valve train segment safety
shutoff valve.
2.
Verify the pressure to the inlet of the ratio regulator
does not exceed the maximum allowable pressure to
the PulsePak valve train segment.
3.
Initiate air source and set air control valve to high fire
setting.
4.
Verify there is enough loading line pressure to the
ratio regulator for gas flow.
5.
Verify there is no pressure rise at the test port on
either safety shutoff valve. If there is a pressure rise,
stop, and investigate if the valve seats may be
leaking.
6.
Apply power to the upstream shutoff valve. Verify
there is a pressure rise on the upstream shutoff valve
test port and there is not a pressure rise at the down
stream shutoff valve test port. If there is a pressure
rise at the down stream shutoff valve, stop, and
investigate if the valve seat may be leaking.
7.
Finally apply power to both shut off valves and verify
there is a pressure rise at the down stream shutoff
valve as well.
Safety Shutoff Valve Seat Leak Test
The safety shutoff valve seats should be tested whenever
there is an event that raises the possibility of
contamination entering into the valve. Because valve
seats can deteriorate over time, the test should be
performed at least annually.
Ŷ
Take care when performing the test since small
amounts of flammable gas will be released into the
local area. Ensure adequate ventilation.
Prepare a glass with water and insert one end of flexible
tubing to a depth of 1/8 to 1/4 inch or 3 to 6mm. With the
burner shut off and gas supplied to the ratio regulator
perform the following test:
1.
Close the downstream manual valve.
2.
Bleed trapped gas by opening the leak test ports on
both shutoff valves.
3.
Connect the free end of the tubing to the port on the
upstream shutoff valve.
4.
If bubbles appear immediately and continue, the
upstream valve seat is leaking and must be serviced;
otherwise wait 30 seconds to charge the volume
between the valve seats.
5.
Count the bubbles for the next minute; if the number
is greater than that allowed by local standards then
the valve must be serviced; see the following chart for
guidelines.
