Class Description

This class teaches students how to conduct specific tests dealing with houses that have vented or un-vented combustion appliances. These tests help ensure the house that you are about to work in is safe and if the house to have work performed can still be safe with a combustion appliance after the work has been completed. These tests are carbon monoxide, CAZ Worst Case Depressurization, Spillage Test, Flue Vent Draft Test. These tests are all run with all of the equipment learned in the E-821 Blower Door & Duct Blaster course. This class requires special equipment such as: Carbon Monoxide Detector, Gas Leak Detector, Manometer, and Combustion Analyzer.

This class teaches you how to look at three major issues: 1) the carbon monoxide levels of the gas and oil fired equipment; 2) backdrafting of all vented appliances; and 3) safety hazards, such as gas leaks and cracked heat exchangers.

The two major reasons for conducting combustion tests on your house are for your customer’s health (potential carbon monoxide exposure & poisoning) and their safety (fire prevention).

Prerequisites

Prerequisite coursework:

• E-820 - Introduction to Energy Efficiency
• E-821 - Blower Door & Duct Blaster Training

Success will depend in part on your ability to learn and retain information in a short period of time. Candidates must be able to perform math at a 11th grade level or higher level to be successful.

Course Objectives

Upon Completion of this course, the student will have the ability to:

• How to properly set up a house for conducting a nationally recognized method for conducting carbon monoxide, CAZ worst case depressurization, spillage, and flue vent draft test
• How to know what is considered acceptable and dangerous testing levels
• Learn how to detect the indication of danger from flame roll out and poor venting from combustion appliances
• Learn the procedures for detecting gas leaks in the gas supply system to the appliance

Student Evaluation

Student performance is evaluated on the basis of:

• Class participation
• Lab participation
• Completion of assignments
• Attendance

Attendance Policy

It is expected that students will attend scheduled classes regularly and on time. If an absence occurs, it is the responsibility of the student to make up all missed work. Students, who must withdraw from a class, will receive credit for work completed and may complete the course at a later date with instructor approval. Attendance will be tracked and maintained for various reporting purposes.

Accreditation and Evaluation

The curriculum for this course is based on the National Mortgage Industry Standards and the course is accredited by the Residential Energy Network (RESNET) and Building Performance Institute (BPI). In keeping with the standards of this accreditation, students are encouraged to provide informal feedback throughout the course. A survey is distributed to students on the last day of class whereby students are asked to evaluate the class and the instructor. This feedback is used to create an on-going professional development plan for instructors and to inform course improvements.
