Pilot Ignition Problems on a Heatilator Gas Fireplace

Pilot Ignition Not Sparking

The absence of flames even after the sparks always indicates that the gas supply is malfunctioning for some reason. Either because of the cylinder, or the valve, or even the supply pipe.

First make sure that there is gas inside your cylinder. An empty gas cylinder can definitely be a cause for the flame not starting. You can easily replace the cylinder yourself.

A turned off gas valve if often another cause for this silly problem. However, if the valve is turned on, and yet the flame is not lighting up, the problem might be with the supply pipe.

Your gas supply pipe might have a leak, or it could be congested. An easy fix for this problem is to replace the gas pipe.

How To Replace A Gas Supply Pipe?

  1. Turn the knob on the gas cylinder to completely shut off the gas supply.
  2. Turn the gas valve inside the fireplace all the way down.
  3. Remove the old pipe either by pulling it out, or if it is tightly secured with a lock, remove the lock and then the pipe. Do this for both ends.
  4. Insert the new pipe into both the cylinder end as well as the fireplace.
  5. Secure them to both ends using metal locking strips to prevent gas leakage.

Pilot Flame Can’t Start the Fireplace

A heat sensor issue is often the case for the fireplace not starting. There are a few different problems that might be causing the issue such as the distance between the sensor and the flame, or a faulty sensor.

If the heat sensor is too far from the flame, which often happen due to the heat bending metal components, the fireplace will not start.

How To Bring The Sensor Closer To The Flame?

  1. Make sure both the gas and the electricity is turned off.
  2. Take a wooden sturdy stick, and gently push the sensor in the direction of the flame.
  3. Make sure the sensor does not touch any side of the fireplace.

But however if the main culprit is a faulty sensor, the only solution is to change it entirely. For which the help of a professional is required.
