Q: Is it better to vent a gas water heater out of the wall or roof?

• <div><p>Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you&rsquo;re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.</p></div>

Q: Do installations include venting and gas connections?

• <div><p>Yes, professional services typically include venting, gas line installation, and necessary permits.</p></div>

Q: How often should I have my gas system inspected?

• <div><p>Consider an annual inspection conducted by a local plumber to prevent dangerous and destructive leaks. If you recently moved into an older home or are concerned about the age of your gas lines, call an inspector for a closer look. You may also be required to call an inspector after your contractor installs a new line for an appliance. </p></div>
