Special Inspection-Field Evaluation Services for Gas-Fired Equipment in Canada

Simplifying compliance for gas-fired equipment in Canada

When installing gas-fired equipment in Canada, meeting the B149.3 Gas Code requirements is essential to gain approval from local code authorities. UL Solutions in Canada offers reliable and efficient services through our Field Evaluation Program for unique or limited-quantity equipment.

What is a field evaluation for gas-fired equipment?

Unlike full product certification, which may involve destructive testing, the UL Solutions Field Evaluation Program is a one-time, on-site evaluation of gas-fired equipment. Designed specifically for one-of-a-kind or limited production equipment, this program helps demonstrate compliance without the need for extensive certification processes.

The UL Solutions field evaluation provides:

• On-site convenience at the installation location
• An assessment of compliance with B149.3 Gas Code requirements, including construction features and critical safety device testing
• A serialized ULC Gas Field Evaluation label and a final report to satisfy code authorities

Eligibility for field evaluation

Many types of gas-fired equipment are eligible for evaluation, including:

• Appliances and equipment that burn gas, such as process heaters, turbines and incinerators
• Stationary gas appliances
• Mobile equipment, with code authority approval

The program is ideal for situations such as:

• Relocating previously approved equipment 
• Developing new products and assessing compliance
• Upgrading a fuel train or control system on existing equipment
• Equipment without an existing certification standard under the B149.3 Gas Code

Why the B149.3 Gas Code matters

The B149.3 Gas Code specifies minimum requirements for fuel-related components. The UL Solutions Field Evaluation Program includes:

• Assessing mandatory construction requirements
• Witnessing critical safety device function tests
• Performing final inspection at the installation site, with optional pre-installation assessments

Compliance with the B149.3 Gas Code helps prove that your equipment meets Canadian safety standards and satisfies local authorities.
