Recall Repair Notice - October 31, 2020

GrillBlazer has discovered that some early production torch guns have, over an extended period of time and temperature change, started leaking gas out from under the Red Knob at the top of the main gas control valve.

It appears to be only a very small percentage of the products made before the spring of 2020, but out of an abundance of caution, we are posting this notice asking everyone who has purchased or received one prior to October 2020, to please pay attention to this potential hazard and to ask them to please contact GrillBlazer immediately for a repair if their torch gun ever develops a leak in this area.

The Problem:
There are two O-ring seals on the main valve stem that are supposed to prevent the gas from leaking out of the top of the valve up under the Red Knob. It appears that the valve manufacturer had some slightly undersized O-rings mixed into their inventory of O-rings during the assembly, and those O-rings have started to leak over a long period of time and with temperature fluctuations.

The Potential Hazard:
The torch could develop a propane gas leak from the top of the valve under the Red Knob, which if ignited will cause fire to come out from under the knob at the top of the valve. Fire in this area can be extremely dangerous, causing bodily injury, property damage or even loss of life.

How to check to see if you have a leak:
When the O-rings fail, the problem will be obvious and easy to spot:

  1. Turn off the main gas valve and connect the torch to a pressurized propane bottle or tank.
  2. Listen and smell for the presence of propane gas leaking out of the torch valve from under the Red Knob.
  3. If you hear any gas leaking out, or smell any propane coming out from under the knob, then it has a leak.

Note: Your user's manual admonishes you to always check for leaking gas before using this or any other propane torch.

What to do if you have a leaking torch:
The main valve stem needs to be replaced with a new one containing larger O-rings.

We have two options for you to choose from for getting it repaired.

  1. If you are at all mechanically inclined, or know someone who is willing to make the repair for you, then we can send you a replacement valve stem free of charge, for you to install on your own
  2. You can send us your torch and we will replace the valve stem for you.

Instructions for repair:
Replacing the valve stem is a quite simple Do-It-Yourself repair, as long as you have access to and can handle small wrenches and can follow simple instructions.
