Gas Codes Inspection
In Alberta, under the Safety Codes Act, Gas Code Regulation, all industrial gas-fired appliances and equipment shall be inspected by a Standards Council of Canada (SCC) accredited Certification Body or Inspection Body. We offer services ranging from complete asset compliance management to field approvals to in-house information presentations.

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.
