Class Schedule

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

Class Overview:

This four hour session covers the science and application of airflow principles to the efficient operation of HVAC equipment. Many of the residential systems in California suffer from the inefficiencies caused by high static pressure. Included in this training is a hands-on portion designed to compare various filters, fittings and layout issues that cause high static pressures.

Class Overview:

Properly maintained and calibrated equipment insures measurement accuracy in the field and improves equipment performance and longevity. Attendees will have the opportunity to check HVAC, blower door and duct tester equipment calibrations. Instructor Gary Wollin will show attendees how to apply the principles for calibrating digital thermometers, refrigerant gauges (P/T) and pipe clamps used for checking pipe temperatures for both the liquid and suction lines. Attendees will be shown the field test procedure for digital manometers and be able to check personal manometers against newly calibrated manometers. Duct blaster inspections for proper airflow will also take place. There will be a demonstration on how to maintain duct blaster equipment including cleaning and checking for damage, and misalignment of the fan and plugged orifices.
