FILTER & FUEL TANK:
The heater’s fuel filter should be replaced before each
heating season, after seasonal or long-term storage
of the unit, or whenever a clog or poor fuel quality is
suspected. Being careful to catch and contain any fuel
that may spill, rotate the filter element to separate it
from the filter head. Replace the filter with a genuine
SunFire filter element. Apply a small amount of clean
oil to the rubber o-ring. Tighten the filter snugly after
the o-ring contacts the filter head. Do not over tighten.
The heater’s fuel tank should be drained after each
heating season, before long-term storage or transport,
or whenever poor fuel quality is suspected. Being
careful and prepared to catch and contain the entire
contents of the tank, use a 1/4” hex key to remove the
drain plug from the tank and allow the contents of the
tank to drain completely. Apply fresh thread sealant,
replace the drain plug, and confirm that it has sealed
properly upon refueling.
The fuel filter and tank should be serviced annually, at a minimum, or whenever a clog or poor fuel quality is
suspected. Over time, water and silt can collect in the fuel tank and should be removed by draining the tank.
REPLACING THE FUEL FILTER:
DRAINING THE FUEL TANK:
The heater’s fuel system will need to be primed after the unit’s fuel filter or tank is serviced, or
when the heater has been run out of fuel. Use the PRIME switch on the back of the burner housing
to prepare the heater for normal operation.
Maintaining your heater is important for prolonging the life of the product and keeping it operating in peak
condition. Inspect the heater before each use and return the unit to optimal condition before resuming normal
operation. Perform regular maintenance on the heater at the beginning and end of each heating season.
Any time a component or any part of the burner is disassembled or replaced for service or
maintenance, perform a complete operational test after reassembly to verify that the heater
operates correctly. Failure to verify proper operation could result in severe personal injury, death,
or substantial property damage.
