EPA Core and Type II @ Johnstone Supply/Fresno
Oct 19 all-day

Class Overview:

This class will consist of a 5-6 hour guided study session for the EPA 608 exam, followed by a closed book, on-line certification exam. This certification is required for all raters who wish to perform refrigerant charge verification. The cost of the exam is $50. The 5-6 hour guided study session and study guide are free. If you already own the Mainstream Engineering EPA 608 study guide, you only need to pay the test fee. We will NOT be covering the Type I or Type III materials. We will only be covering the Core materials and the Type II materials. You are free to take whatever parts of the exam you want to, but HERS raters only need to be Type II certified to perform refrigerant charge verification for Title 24 purposes.

Combustion Safety @ Johnstone Supply/Bakersfield
Oct 20 @ 8:00 am – 12:00 pm

Class Overview:

This training will go into depth on how to conduct a Combustion Safety Test (CST) in the Combustion Appliance Zone CAZ under Worst Case Depressurization (WCD).

The following topics are covered:

  • How to prep the CAZ
  • Set up pressure gauges, measure and record baseline pressure and WCD pressures
  • Firing heating appliances and identifying if the appliances will draft within 60 seconds
  • Conducting measured draft and CO Reading at steady state
  • Scenarios if the appliances fail CST
  • Steady state and/or ambient CO problems
  • Identifying potential venting problems
  • Recommendation based on Combustion air venting tables
