Using It on the Job

1. Ensure the gas supply and electrical power to the heater are isolated and locked out before commencing work.
2. Gently pull the old knob straight off the control shaft. It might be stiff if it hasn't been removed in a while.
3. Inspect the control shaft for any damage or debris. Clean if necessary.
4. Align the new black knob with the shaft and press it firmly into place until it seats correctly.
5. Restore gas and power, then test the knob's operation through its full range.

Limitations & Safety Notes

• This knob is only compatible with Vulcan 49 Series gas heaters. Verify your unit's model before purchase.
• Always isolate gas and electrical power before attempting any repairs on a gas appliance.
• Work on gas appliances should be performed by a licensed professional in accordance with Australian standards.

Before you toss the old knob, double-check the shaft type – some older models had D-shafts while others were splined. This replacement is designed for the standard Vulcan 49 Series shaft, so confirm it matches your existing setup for a clean fit.
