Gas Heating: Furnaces, Boilers, Controls and Components Course

For those that maintain, service and install gas heating systems or those just looking for a more in-depth source of accurate information, this modular training program focuses on furnaces and boilers that burn natural gas or LP. The combustion of gas to generate heat can be dangerous and should be thoroughly understood by HVAC technicians. This program covers many facets of gas heating including: combustion, system components and controls, heating sequences, installation, and troubleshooting.

This course includes text and video lectures along with review questions for each module.

Upon successful completion of each module of this course bundle (requires a score of 70% or higher in the end of module review questions), course participants will receive a certificate of completion.

Here's what you'll learn:

Safety
Fuels & Their Properties
Combustion
Fuel System Components
Venting
Electrical Components
Gas Fired Furnace WIring Diagrams and Sequence of Operation
Gas Fired Boiler WIring Diagrams and Sequence of Operation
Gas Pipe Sizing
Installation
Troubleshooting

Enroll in this learning track and begin your journey to improving your understanding of electrical theory and its application in HVACR..

Gas Heating Part 1: Safety

This lesson will provide a general overview of some common safety-related issues that are faced by a technician who works on gas-fired heating equipment.

Gas Heating Part 2: Fuels and Their Properties

Different fuels have different properties. Fuels are selected for use in heating appliances based on their properties including: availability, cost, and varying climatic conditions. In this lesson we will examine each specific fuel & its properties.

Gas Heating Part 3: Combustion

This lesson will provide a general overview of combustion and combustion safety.

Gas Heating Part 4: Fuel System Components

This lesson will cover the basic fuel path through a system; from the pressure regulator, to the gas valve, to the manifold, through the spuds, and finally to the burners. Proper maintenance and replacement of these components will also be covered.

Gas Heating Part 5: Venting

Venting is the process of removing combustion by-products from the appliance and moving them to the outside atmosphere. In addition to removing combustion gases, the venting process creates pressure needed in the appliance to draw in combustion air.

Gas Heating Part 6: Electrical Components and Controls

This lesson will will cover electrical components and controls common to both furnaces and boilers.

Gas Heating Part 7: Gas-Fired Furnace Wiring Diagrams and Sequence of Operations

This lesson will cover wiring diagrams and sequence of operation specific to gas furnaces. We will cover a number of ignition systems using animated wiring diagrams to illustrate the sequence of operation.

Gas Heating Part 8: Gas-Fired Boiler Wiring Diagrams and Sequence of Operations

This course will cover boiler wiring diagrams and sequence of operation. This course provides detailed text and images as well as video lecture to aid in comprehension of the materials. End of course review questions will test your comprehension

Gas Heating Part 9: Gas Pipe Sizing

This lesson will cover gas pie sizing and system design.

Gas Heating Part 10: Installation

This course will cover gas heating system installation best practices - both forced air and hot water.

Gas Heating Part 11: Troubleshooting

This lesson will cover meter use and system troubleshooting.
