Air Pressure Problems

Always use an air pressure gauge to check or set air pressures.

DFA-45 2.8 PSI DFA-170T,170C 6.5 PSI
DFA-65 3.5 PSI DFA-210T,210C 8.5 PSI
DFA-120,120T 4.5 PSI

If the pressure is TOO LOW turn the adjustment screw clockwise. This will increase the flame.

If the pressure is

Note: If the heater burns OK with the Upper Shell off, but turns off when the cover is installed, the
pressure is too low.

If you can't achieve the proper pressure setting - try pulling the air line off the pump body and block
air line fitting tight

This should peg pressure gauge. If it does not, the problem is inside the pump body.

Check for: Cracked plastic cover

Sometimes it's hard to see the air leak. A solution of 50/50 soap and water can be applied to the
pump to find the leak.

CAUTION! BE CAREFUL NOT TO APPLY THIS SOLUTION TO ANY ELECTRICAL PARTS AS
IT WILL DAMAGE THE COMPONENTS AND CREATE A SHOCK HAZARD.

If pressure gauge does peg - try removing the air line from the nozzle end and replace it at pump
body end. Then plug air line and adjustment screw end. If it
