Step-by-Step Pilot Lighting Procedure
Successfully lighting your Heat & Glo pilot requires a precise sequence of actions. Begin by ensuring the fireplace is cool and the area is well-ventilated. Turn the gas supply on at the shut-off valve, typically located near the fireplace. Next, set the control knob to “Pilot” – do not attempt to light the pilot in any other position.
Press and hold the igniter button; you should hear a clicking sound, creating a spark at the pilot orifice. Simultaneously, observe the pilot area for a flame. If the pilot lights, continue holding the igniter button for approximately 30-60 seconds. This allows the thermocouple to heat up and maintain the gas flow.
Slowly release the igniter button. If the pilot remains lit, proceed to turn the control knob to the “On” position. If it extinguishes, repeat the process, allowing more time for the thermocouple to heat.
Turning the Gas Supply On
Before attempting to light the pilot, verifying the gas supply is crucial for safe operation. Locate the gas shut-off valve, typically positioned near the fireplace or gas meter. Ensure it’s in the “on” or “open” position; this valve controls the gas flow directly to your Heat & Glo unit.
Slowly turn the valve handle, usually a quarter-turn, to allow gas to flow. Listen for a slight hissing sound, indicating gas is reaching the fireplace. If you smell gas at any point, immediately shut off the valve and ventilate the area – do not proceed further.
Double-check all connections for leaks using a soap and water solution (see “Post-Lighting Checks”). A consistent gas supply is fundamental for successful pilot ignition and consistent fireplace performance. Remember, safety is paramount when dealing with gas appliances.
Setting the Control Knob to “Pilot”
With the gas supply safely established, the next step is to position the control knob correctly. Locate the control knob on your Heat & Glo fireplace – it’s usually near the gas valve. Gently turn the knob counterclockwise to the “Pilot” setting.
Do not force the knob; it should move smoothly. The “Pilot” position allows a small amount of gas to flow to the pilot assembly, preparing it for ignition. Crucially, do not turn the knob further than the “Pilot” setting at this stage.
Holding the knob in the “Pilot” position is often required during ignition to maintain gas flow. Many users inadvertently light the pilot and then forget to return the knob to the “On” position, preventing the main burner from igniting; Ensure you understand your model’s specific requirements.
Pressing and Holding the Igniter Button
With the control knob firmly set to “Pilot,” it’s time to activate the igniter. Locate the igniter button – it’s typically red or black and positioned near the pilot assembly. Press and hold this button down.
Continuous pressure is essential; releasing the button prematurely will interrupt the sparking process. You should observe a series of sparks emanating from the igniter, directed towards the pilot opening. This spark is designed to ignite the gas flowing from the pilot orifice.
If you don’t see a spark, double-check the igniter button’s position and ensure it’s fully engaged. Some models may not have a visible spark igniter button, requiring alternative ignition methods. Continue holding the button for at least 30-60 seconds, even if the pilot doesn’t light immediately.
Observing the Pilot Flame
After consistently holding the igniter button, carefully observe the pilot opening for a flame. A successful ignition will manifest as a steady, blue flame enveloping the pilot burner. This flame should be robust and consistent, indicating proper gas flow and combustion.
Continue holding the igniter button for approximately 30 seconds after the pilot flame ignites. This ensures the thermocouple or thermopile heats up sufficiently to maintain a safe and reliable connection. Once the pilot flame is established, slowly release the igniter button.
If the pilot flame remains lit after releasing the button, you’ve successfully lit the pilot. However, if the flame extinguishes immediately upon release, revisit the troubleshooting section to address potential issues like a faulty thermocouple or insufficient gas supply. A stable pilot flame is crucial for safe operation.
Troubleshooting: Pilot Won’t Light
If the pilot refuses to ignite despite repeated attempts, systematic troubleshooting is essential. First, verify a sufficient gas supply by checking the main gas valve is fully open. A lack of gas is a common culprit, preventing the pilot from receiving fuel.
Next, inspect the thermocouple or thermopile. A faulty component won’t allow the gas valve to stay open, extinguishing the pilot. Testing and potential replacement may be required. Also, examine the pilot tube for any obstructions or dirt buildup, as this can impede gas flow.
Air trapped within the gas line can also hinder ignition. Purging the system to remove air pockets might resolve the issue. Remember to consult the service documentation for your specific Heat & Glo model for detailed instructions. If problems persist, professional assistance is recommended.
