MAINTENANCE

During maintenance, with respect to software and setup, visual inspection should be done to
determine the following:
What is the firmware version being used?
•
What are the appliance specific settings? An example list of settings can be found below
•
o Is Pressure used? Is Level Used? Is TCV Used?
o Is Pilot 2 Used? Is Outlet Temp Used? Is Stack Temp Used?
When gas fitting installation is done, a visual inspection should be done to determine the following:
Whether drip legs are installed on the final drop and condensation points?
•
Whether the pilot piping is taken off the top or the side of the supply and not the bottom?
•
Whether piping and fittings are clear from burrs and defects?
•
Whether an overpressure protection device is required and installed?
•
Whether the regulator is of a positive shut off type for supply above 0.5 psig?
•
Whether gas pressure is indicated at shutoff valves and penetrations are required?
•
Whether piping is supported securely and the support spacings do not exceed 8 feet?
•
Whether gauges are correctly sized to match the pressure range?
•
• Whether the gas line is painted or marked according to code?
• Whether swing joints are installed if they are required?
• Whether all exposed gas piping is painted?
Whether the ends of piping are reamed?
•
Whether the appliance vents are mounted securely?
•
Whether all indicators and gauges can be read easily?
•
Whether gas shutoffs in the upstream pilot valve train are present and easily accessible?
•
2. In the case of a dry contact, ensure the PWR terminal is connected and is
sourcing the correct voltage.
3. Ensure adequate amount of wetting current is being applied to through
contact.
Run a current meter in series with the digital input switch and
•
verify the energized state meets the requirements outlined in the
"Electrical and Mechanical Ratings" section of this document
If there is not adequate wetting current, the digital input either
•
has too high of an impedance or the wiring has been
compromised
