Pressure / Filtration
SAMPLE PRESSURE at the SAMPLE inlet should be within
the range 345 to 620 hPa-gauge (5 to 9 psig nominal),
and internally, should be between 206.7 and 275.6 hPa-
gauge (3.0 and 4.0 psig).
BURNER FUEL PRESSURE should be:
3101 to 3450 hPa-gauge (45 to 50 psig) for cylinder regu-
lator, 1723 hPa-gauge (25 psig) nominal for internal pres-
sure.
BURNER AIR PRESSURE should be:
1725 to 3450 hPa-gauge (25 to 50 psig) for cylinder regu-
lator, 1035 hPa-gauge (15 psig) nominal for internal pres-
sure.
REGULATED AIR PRESSURE should be:
689 to 1725 hPa-gauge (10 to 25 psig) for cylinder regu-
lator.
PURGE AIR PRESSURE should be:
689 to 1380 hPa-gauge (10 to 20 psig).
NOMINAL INTERNAL CASE PRESSURE is about 0.5 to 1.0
inch of water, and the pressure relief valve is set at 1/3
psig (nominal).
OVER PRESSURE DAMAGE
Noncompliance with these specifications,
particulary tose concerning purge air, could cause
over-pressure damage to the module.
CAUTION
2-5 LEAK TEST
The Analyzer Module is completely tested at the factory
for gas leakage (leakage rate - 7.5 hPa/min. (- 0.11 psig/
min.) with He or - 2.5 hPa/min. (- 0.036 psig/min.) with
N
2
). The user is responsible for leakage testing at the
inlet and outlet fittings on the rear panel minimum twice
a year (see Section 4-13).
The user is also responsible for internal leak testing pe-
riodically and if any internal pneumatic components are
adjusted or replaced (with a test procedure chosen by
the user).
