Frequently Asked Questions
Napoleon E1 error only in winter when heating is on high — cause?
E1 occurring only on the high heat setting with adequate clearance may indicate a slightly over-sensitive thermal sensor. Try running on the medium or low heat setting. If E1 does not occur on a lower setting, the heater is operating at its thermal limit.
Napoleon fireplace E1 cleared but E1 keeps coming back every hour — why?
Recurring E1 every hour suggests the unit is overheating during normal use due to an internal component fault (e.g. a failing fan that should be cooling the heating element). Contact Napoleon support.
Napoleon E1 error appeared the first time I used the unit — is that normal?
E1 on first use can indicate the unit was installed with a vent blocked or pressed against a wall. Check that all four sides and the top of the unit have clear space as specified in the installation instructions.
