Valve Safety Features
A Flame out relates to the oil level and the float level in the oil metering valve. In the
event that the heater flame is blown out, oil will continue to accumulate into your burner
pot to the depth of 9/16 inches and no more. This oil must be removed from the pot
before the heater is lit again or the heater will dangerously overheat.
A high temperature fuse is incorporated into the oil metering valve. The adjusting screw
on the knob of the oil metering valve is fitted with a fusible sleeve. This fuse will melt if
the valve knob reaches a temperature of 165 degrees F. This will shut-off the flow of oil
into the burner. . Under normal conditions the valve is at room temperature. If the high
fire sleeve melts it indicates too much heat in the burner. Overheating of this kind is due
to incorrect operating procedures (the flames are burning down in the burner pot) and
should be rectified before an overheat occurs again. In case of the release of the fusible
link, a replacement part is available from Sig Marine or just remove the brass nut (do not
move the adjusting screw) and apply heat from a lighter to re-solder the link back into its
original position (flat on the top). Once back in place the adjusting screw will not need
re-adjusting.
DO NOT ALLOW FLAMES TO BURN BELOW TOP RING.
DO NOT LEAVE YOUR HEATER BURNING UNATTENDED
Burner Assembly
Your diesel heater/stove has been equipped with a 4.5” or 5.5” Sig burner. There are
two components in the burner that must be correctly placed for the heater/stove to operate
properly. The burner ring must be placed at the top of the pot so the outside edge of the
ring fits into the groove in the top of the pot. Ensure that the ring fits in evenly and snugly
all the way around the pot and that all of the oval shaped slots are clearly visible.
The second component is the superheater. The superheater is placed through the burner
ring and will sit on the bottom of the burner with the round 2” disc sitting 2” up from the
bottom of the burner .
The flat legs on the bottom of the superheater should sit flat on the
bottom of the burner to radiate heat to the fuel coming in through the center of the
superheater . This will need to be kept clean to allow fuel to flow through it. The upper
legs of the superheater will sit up above the burner ring where the flames are and radiate
heat down to the vaporizing fuel.
The 2” round disc sitting 2” above the bottom of the burner is to deflect the hot rising
vapor up the sides of the burner pulling in the primary air needed to mix with the fuel.
