All types of blow lamp work in the same way. To use a blow lamp, follow these steps:
Blow lamp attached to a gas cannister

Step 1 – Attach gas canister

To use your blow lamp you will first need to attach the gas canister. To do this, hold the canister and place the blow lamp coupling over the valve. Whilst placing a slight pressure on the blow lamp, twist it onto the canister in a clockwise direction, until it has been hand tightened.

Step 2 – Leak test

Next you will need to check the connection between the canister and the blow lamp to ensure there is no gas leaking. To do this, apply a gas leak detector spray to the connection. If any foam appears, gas is leaking and the blow lamp must be removed from the canister and replaced.

If no foam appears, then proceed to the next step.

Step 3 – Adjust flame control knob

To light a blow lamp, whether it is manually or with a piezo ignition, you will need to twist the flame control knob in an anti-clockwise direction. Twist the valve a quarter turn to allow the gas to exit the canister. When you have done this you will be able to hear the gas hissing, which will allow you to ignite the lamp.

Lighting a heavy duty blow lamp with a lighter If your blow lamp does not have a piezo ignition then you will need to light it manually with a match or lighter. To do this, light a match and hold it just below the burner until the blow lamp produces a flame.

Make sure you do not place the match directly in front of the burner as this could cause you injury.

To adjust the flame, continue turning the flame control knob in an anti-clockwise direction until you are satisfied with the size of the flame.

If you are using a swivel blow lamp, you can adjust the direction of the burner tube by grasping the blow lamp case and twisting the burn tube into the desired position.
