Maintenance - Stanley ST-80T-KFA Instruction Manual

NEVER LEAVE HEATER UNATTENDED WHILE BURNING OR WHILE CONNECTED TO A POWER SOURCE

MAINTENANCE

SERVICE:
DO NOT TAMPER WITH THE UNIT. HAVE A COMPETENT
SERVICE MEMBER MAKE ANY NECESSARY ADJUSTMENT OR
REPAIRS.
Use only original equipment parts. Using alternate or third
party components can cause unsafe operating conditions and
will void your warranty.
We suggest following a maintenance schedule as follows:
FUEL / FUEL TANK:
Flush tank every 200 hours of operation or as needed.
DO NOT flush with water; use fresh K-1 kerosene only.
AIR FILTERS:
The air intake filter should be replaced or washed with soap
and water and dried thoroughly every 500 hours of operation,
or less depending on conditions.
The output and lint filters should be replaced every 500 hours
of operation or less depending on conditions. See Figure 4
NOTE: Use of diesel fuel may require additional
maintenance.
FAN BLADES:
Blades should be cleaned at least once per heating season,
depending on conditions. Remove all accumulated dust and
dirt with a damp cloth, taking care not to bend any of the fan
blades. Be sure the blades are dry before restarting the heater.
FUEL FILTER:
The fuel filter should be cleaned at least twice per heating
season. Clean the filter by rinsing it in clean K-1 Kerosene.
Contaminated fuel could make cleaning the fuel filter
necessary immediately.
NOTE: To remove the filter from model 80T-KFA, turn
filter 90º clockwise. To remove the filter from models
140T or 215T-KFA, turn filter 90º counterclockwise. See
Figure 3.
THERMISTER PLACEMENT:
Ensure the thermister wire is in the proper place. The wire
should be lying on the bottom shell inside the heater with the
plastic end placed under the motor support/motor and away
from fan blade.
ROTOR:
The rotor with carbon vanes should be evaluated every
heating season. The rotor is behind the air filters. The vanes
should be inspected for damage or wear. The rotor should be
inspected for damage, chips, wear, cracks.
Check rotor gap: Remove the rear cover. Loosen the two pump
ring screws. Lift the pump ring upwards. Insert a 0.1 mm feeler
gauge and apply slight downward pressure, enough to offer
resistance when attempting to remove gauge.
Hand-tighten the two pump ring screws. Re-install the End
Pump Cover and the plastic End Filter Cover. Start the heater
and adjust to the proper pump pressure.
