Field Approvals

RAE Gas Code Inspections (RGCI) is a subsidiary of RAE Engineering and is a SCC accredited Inspection Body (RGCI IBAP Scope of Accreditation), offering field approval inspections of gas-fired appliances and equipment.
Field approval inspections are to be compliant to CSA B149.3 and must be completed onsite after installation.

The field approval process for existing and new gas-fire appliances include:

• Documentation Review
  Prior to performing site inspections, the documentation of the gas-fired appliance shall be reviewed for compliance to CSA B149.3. Any deficiencies or non-compliant items will be identified to allow the client to address the issues prior to site inspection.
  Documentation that shall be reviewed shall include Process and Instrumentation Diagram (P&ID), Bill of Materials (BOM), wiring diagram, burner management system specification, operating narrative or other suitable operating instructions, electrical area classification, overpressure protection of the fuel train, commissioning/combustion report, purge calculations, etc.
• Shop Inspection
  Shop inspections assure the gas-fired appliance is in compliance with CSA B149.3 prior to shipping, ensuring any deficiencies or non-compliances are dealt with prior to getting to site.
• Site Inspection
  After the documentation review is completed, the site inspection can be scheduled and performed. Site inspections verify the installation is compliant.
• Reporting and Labeling
  Once site inspection is completed and the gas-fired appliance is deemed compliant an Inspection Label (with a unique RGCI Identification number) is affixed to or near the appliance confirming the gas-fired appliance is field approved. The report is completed (include a stamped Inspection Certificate) and provided to the client.It is noted that some gas-fired appliances do not have a proper Rating Plate as required by CSA B149.3. As requested by the client, RGCI can prepare a Rating Plate based on the documentation provided.

Compliance Assessment

Not ready for field approval or know if your gas-fired appliances require upgrades? RGCI provides compliance assessments to determine the deficiencies of your gas-fired appliances. Compliance assessments may include a document gap analysis and/or a site gap analysis. It is recommended that both the document gap analysis and the site gap analysis be performed to get a complete assessment of your gas-fired appliance.

• Document Gap Analysis
  The gap analysis would identify any deficiencies or non-compliant items, giving the client and an indication of what upgrades would need to be considered. Documentation that shall be reviewed shall include Process and Instrumentation Diagram (P&ID), Bill of Materials (BOM), wiring diagram, burner management system specification, operating narrative or other suitable operating instructions, electrical area classification, overpressure protection of the fuel train, commissioning/combustion report, purge calculations, etc.
• Site Gap Analysis
  Site gap analysis should be completed if there is little to no documentation on the gas-fired appliance.
  The site inspection of the gas-fired appliance can be inspected as part of a CSA B149.3 compliance gap analysis. This gap analysis would identify any deficiencies or non-compliant items, giving the client and an indication of what upgrades would need to be considered. As requested by the client, RGCI can assist in preparing the P&IDs and BOM as part of the site gap analysis.
