Replacing the Evaporator Wick
Overview
Replace the evaporator wick if error codes 58, 59, 60, 61, or 62 occur
repetitively for ignition or flame failures respectively. You should check and
replace evaporator wick as needed before deciding to replace the FID.
Replace the evaporator wick every 500 hours of operation for optimal
running.
You must remove the FID before you remove the evaporator.
Removing the evaporator with the FID in place will damage the FID.
Only replace the gasket with a genuine WhisperGen
TM
gasket.
Do not use other gasket material.
It is advisable to keep a spare evaporator wick with the
WhisperGen
TM
at all times.
Procedure
To replace the evaporator wick:
1. Remove the FID. Inspect the FID for wear or damage.
2. Remove the glow plug. Inspect the glow plug for wear or damage.
3. Turn off the WhisperGen
TM
fuel valve.
4. Unscrew the fuel line fitting on top of the burner.
5. Undo the four screws on top of the evaporator with a 4mm allen key.
6. Lift the evaporator out of the burner.
7. Remove the evaporator gasket. Replace it if it is not flexible or if it is
damaged.
8. Remove the evaporator sleeve (1) from the evaporator body (2) using
a bearing puller if the sleeve is too tight to remove by hand.

9. Remove the wick and discard. Remove all carbon build up on the
evaporator body using a wire brush or sand paper. Use a small
screwdriver to remove deposits on the wick cavity.
10. Fit a new wick onto the evaporator body and not into the evaporator
sleeve. Note that incorrectly fitting a wick into the sleeve blocks the
sleeve holes and restricts the flame.
