PROBLEM CAUSE
See
Above
SOLUTION
Black smoke/exhaust
coming from unit
Bad fuel, air to fuel mix
ratio, and/or improper
fuel pressure setting.
AST
Black smoke is an indication that the burner is receiving
more fuel than it needs to operate efficiently. Call authorized
service center or HVAC specialist.
Grey or white exhaust/
smoke coming from
unit
Water in the fuel and/or
too much air in the
fuel/air mixture.
AST If water is present in the fuel, the fuel tank will need to be
drained and the fuel filter will need to be replaced prior to
attempting to operate the unit. If the fuel does not contain
water, then the fuel to air ratio is the most likely cause of the
grey/ white discharge. Call authorized service center or
HVAC specialist.
For the location of an authorized service center for your Dragon K85 Mobile Furnace, contact your
local distributor or the Dri-Eaz Service Department at 1-888-867-3235.
