General Espar Maintenance
Recommended Periodic Maintenance
- Remove the glow pin and inspect for carbon build up. Clean or replace.
- Remove the glow pin screen and inspect for carbon build up. Replace.
- Make sure the vent hole is not clogged.
- Inspect the ducting, the air intake screen, and air outlet for restriction or blockage.
- Inspect the combustion air intake and exhaust for blockage.
- Operate your heater for a minimum of 20 minutes each month.
- Maintain your batteries and all electrical connections in good condition. With insufficient power the heater will not start. Low and high voltage cutouts will shut the heater down automatically.
- Use fuel suitable for the climate (see fuel supplier recommendations). Blending used engine oil with diesel fuel is not permitted.
Other Maintenance Tips:
- Be sure the van's battery system is receiving sufficient voltage; check the incoming voltage on your van's inverter monitor screen. If the battery system has low voltage, the Espar will not be able to start.
- Know whether your Espar runs on gasoline or diesel and use the appropriate fuel when refueling your van.
- Periodically do a visual check of all electrical lines and connections for damage or corrosion.
- Periodically do a visual check of the fuel line for leaks.
- Make sure the exhaust pipe (photo below) is not touching the electrical or fuel lines, as it may cause these lines to melt.
- Periodically check and replace the fuel filter inserts.
- Periodically check the glow pin (photo below) and replace as necessary.
- Once a year, replace the screen, filters, and gaskets.
- Periodically inspect the blower motor for visual signs of damage.
- Periodically inspect the duct system, and make sure there is no contamination, dust, or blockages.
