Maintenance: ST-70-SS-E / ST-70T-SS-E / ST-125-OFR-E
Long Term Storage:
1. Unscrew the fuel cap.
2. Using an approved siphon, remove the
Parafn or diesel.
3. Using a small amount of Parafn or diesel,
rinse and swirl the fuel inside the fuel tank
NOTE: NEVER MIX WATER WITH FUEL. It will
cause rust inside the tank.
4. Empty the tank completely.
IMPORTANT: Never store leftover Parafn
between seasons, using old fuel can
damage heater.
Store Heater in a dry, well ventilated area.
- Be sure that the storage area is free of dust
and corrosive vapors. Repack the heater
in the original packaging and keep user’s
manual in an easily accessible place.
Service:
DO NOT TAMPER WITH THE UNIT. HAVE AN
EXPERIENCED SERVICEMAN MAKE ANY
NECESSARY ADJUSTMENT OR REPAIRS.
We suggest following a maintenance schedule as
follows:
FUEL / FUEL TANK:
Flush tank every 200 hours of operation or as
needed. DO NOT ush with water, use fresh
Parafn only.
SPARK PLUG:
Clean and re-gap every 600 hours of operation
or replace as needed. After removing the Spark
Plug, clean the terminals with a wire brush.
Re-gap the terminals to 0.140” (3.5mm).
(See Figure 7)
FAN BLADES:
The fan blades should be cleaned at least once
per heating season, depending on conditions.
Remove all accumulated dust and dirt with a
burst of condensed air. (See Figure 8)
PRESSURE ADJUSTMENTS:
Proper pressure is dependent on the fuel type
the unit will be running. When smoking or non-
ignition occurs, remove the lower panel. Locate
the brass screw on the fuel pump to the left of the
fuel line.
If you are experiencing smoking or fuel
dripping from the unit, turn the screw clockwise
1/8 to 1/4 of a turn to increase the fuel pressure
until the unit is operating properly.
If you are experiencing extended flames
from the front of the unit, turn the screw 1/8 to
1/4 of a turn counterclockwise to reduce the air
pressure until the unit is operating properly.
TIP: Follow the long term storage
instructions to ush the tank.
Never service heater while it is
plugged in or hot!
