rated speed
7. Loose fuel line
1. Adjust pump pressure ( see
Pump Pressure Adjustment,
page 14).
2. A) Add fuel to tank.
B) Check fuel tank for bubbles
of water in bottom. If found,

at heater should be not less than
90% of rated voltage (108V
minimum for 120V heaters).
7. Check and tighten all fuel line
