Recommended Fuels and Fueling Instructions
CAUTION
Do not overfill tanks. Tanks should be filled to only 90% of the full volume to allow thermal expansion.
Use ULSD No.1 or ULSD No.2 for all heater models except the ES700B-ED. For continuous duty
operation, a daily refilling schedule should be established.
4.2.1
ES700B-ED (aux tank equipped machine) Refueling
Instructions
The ES700B-ED model has an auxiliary fuel tank for the engine. This allows locally approved heating oil
to be used in the burner and ULSD fuel for the engine. Observe machine placards for fuel types and
placement.
CAUTION
ES700B-ED Model: Always refill the auxiliary ULSD tank when filling the main heating oil tank to prevent
engine failure while the heater is operating. Premature generator shutdown can damage the burner.
4.3
Access and Clearance
Ensure all sides of the heater are easily accessible. Heater should be more than 3ft [1m] from any
structure. Heater is correctly placed when the operator can walk around the perimeter of the heater
with minimal obstruction. Check for placement and access of fire extinguisher.
4.4
Leveling
Ensure heater is placed on firm ground and wheels (if equipped) are chocked. Heater should be close to
level across the width (±1°). The heaters should be slightly lower in the front to maximize fuel tank
capacity. For trailer mounted heaters, use the tongue jack to level the heater and then lower the tongue
jack 1 to 2 inches (2.5 to 5cm).
If the heater is placed on frozen ground or ice, frequently check the heater for shifting and
reposition/level as necessary.
