Do you carry inline fuel filters?

Heater will not stay ignited after it is initially lit.
For model number MH9B
Hi Charlscie,
Thank you for your question. If your heater lights for about a minute and then shuts off, the pilot orifice may be clogged with a buildup of carbon. A buildup of carbon can restrict the flow of gas and prevent the pilot heating up the thermocouple. It is important to clean the pilot orifice on a regular basis. We hope this helps!
