ENEFEN performs field inspection evaluations based on Canadian code requirements for the safety and suitability of one-of-a-kind and limited run commercial and industrial fuel-burning appliances. Most jurisdictions in Canada require the appliance and its installation to be inspected prior to use, and ENEFEN is accredited by the Standards Council of Canada (SCC) to do this onsite across Canada. For our clients this accreditation is a verification of the integrity, reliability and technical competence of our inspection services.

ENEFEN Field Approvals have been formally authorized by:

Alberta Municipal Affairs (AMA)
Technical Safety BC (TSBC)
Manitoba Office of the Fire Commissioner
Most jurisdictions in Canada allow an SCC accredited Inspection Body to approve gas-fired appliances.
