MorrHeat - Most Heat In The Industry - Rev 3/18/2019

To insure the best performance, optimal efficiencies and heat output of the heating unit, it is 

recommended and necessary to become familiar with your unit and the procedures needed 

with initially starting, running, cleaning and maintaining the heating unit.

It is important to remember when burning used or dirty oils that contaminants could be 

present.  Because of various contaminates, be aware of needing to change filters when 

needed.  Keep the chamber and heat exchanger(s) passageways clean.  Make sure the fuel 

pump is primed and lines are free of any debris, air bubbles or interuptions.

Draft is just as important as the rest; bad draft can cause serious problems and not allow the 

gasses within the unit to correctly leave the heating unit.  Correct draft is needed for optimal 

performance.  Bad draft will cause over-fire or overheating due to bottling up the heat or 

creating back pressure back in to the heating unit. If black smoke is present, bad draft, bad 

combustion or both is occuring.
