5.
Switch on the gas supply to measure the inlet gas pressure. The gas pressure for
natural gas should be around 7" wc at high fire and 11" wc for propane. If the gas
pressure dips below 3½" wc or exceeds 15" wc, the boiler will shut down. If this
occurs, you will need to reset the gas high or low pressure switch. For instructions,
see
Resetting the gas high / low pressure switches on page 77
.
6.
After completing the inlet gas pressure test, switch off the gas supply.
7.
Remove the inlet gas pressure test fitting and manometer from the inlet gas pressure
test port.
8.
Insert the bolt head and tighten using a 3 mm Allen wrench.
6.3.4 Adjusting the gas valve (EX 400, EX 500)
Danger
Making adjustments to the IBC gas valve without a properly calibrated gas
combustion analyzer and by persons who are not trained and experienced in its use is
forbidden. Failure to use an analyzer can result in an immediate hazard.
To help with the following procedure, see
.
Performing a combustion test
1. Give the boiler a call for heat.
2. When the boiler reaches high fire, insert the combustion analyzer test probe into the flue
gas test port. Then verify that the CO
2
reading is within the combustion test targets at
values.
