Class Schedule

Class Overview:

Learn advanced Manometer settings while conducting a Blower Door test. We will cover methods used to identify and prioritize build shell leakage. Students will learn to set up BD, Manometer, hoses and house in order to conduct a total shell leakage. Learn to calculate the Building Airflow Standard (BAS). We will also cover the importance of comparing the BD results with the BAS when recommending air sealing. Participants will practice methods in field guided by instructor.

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.
