Maintenance
NEVER OPERATE THIS HEATER UNATTENDED! Use 
only original equipment replacement parts. The use of 
alternate or third party components can cause unsafe 
operating conditions, and will void your warranty. We  
suggest following a maintenance schedule as follows:
Filters - The Fuel Filter and Oil Filter should be cleaned at 
least twice per heating season.
Fan Blades -  The fan blades should be cleaned at least 
once per heating season, depending on conditions.
Spark Plug - Clean and re-gap every 600 hours of  
operation, or replace as needed.
Photocell - The Photocell should be cleaned at least once 
per heating season or more depending on conditions.
Fuel/Fuel Tank - Flush every 200 hours of operation or as 
needed.
Long Term Storage
 - Unscrew the Fuel Cap, and using an approved fuel 
siphon, remove paraffin or diesel. 
 -  Using a small amount of paraffin or diesel, rinse and 
swirl the fuel inside of the Fuel Tank. Empty the tank 
fully.
 - NEVER MIX WATER WITH FUEL, as it will cause rust 
inside the tank.  
Never store leftover paraffin or diesel over the  
summer. Using old fuel can damage your heater.
Store heater in a dry, well-ventilated area
