Maintenance - PT70-SS Plus

Service (Continued):

NOZZLES:

Nozzles should be cleaned or replaced at least 

once per heating season. Contaminated fuel 

could make this necessary immediately. To clean 

dirt from nozzle, blow compressed air through 

nozzle front. It may be necessary to soak nozzle 

in clean paraffin or diesel to help loosen any 

particles. (See Figure 13)

PHOTOCELL:

The photocell should be cleaned at least once 

per heating season or more depending on 

conditions. Use a cotton swab and water or 

alcohol to clean the lens of the photocell. 

Be certain to reinstall the photocell in proper 

position as shown below. (See Figure 14)

FILTERS:

The fuel filter and oil filter should be cleaned at 

least twice per heating season by rinsing it in 

clean paraffin or diesel. Contaminated or old fuel 

could make cleaning necessary immediately. 

(See Figure 15)
