Special Instructions - Dri-Eaz Dragon 3600 Manuel Du Propriétaire

NOTICE: Do not unplug the unit or otherwise turn off
the power until the fan stops operating, as this may
interrupt the cooling cycle. Failure to let the unit
complete the cooling cycle could damage the heat
exchanger and will not be covered under warranty.

SPECIAL INSTRUCTIONS

Unit has run out of fuel
WARNING: Replace Burner Access Plate after
each adjustment. Do not operate the unit without
the hood securely in place. Serious injury could
result.
1. Turn the CONTROL KNOB to the "Off" position
(Fig. C).
2. Open Burner Reset Access Plate by removing the
four retaining bolts (Fig. A).
3. Click the BURNER RESET button once quickly
(Fig. D).
4. Turn CONTROL KNOB to the Heat position. The
burner should start as normal.
5. If the burner does not start, repeat steps 1, 3–4.
6. If the burner does not start after two or three
attempts, press and hold the BURNER RESET for
15+ seconds. This initiates a system reset and will
purge the fuel line of any air.
7. The unit will resume normal operation.
Replace the Access Plate.
If unit will not reset after several attempts, contact your
Dri-Eaz distributor for assistance.
Adjusting for proper combustion and
altitude
The combustion air intake control for the furnace is
factory set for operation at altitudes ranging from sea
level to about 5000 ft. (1500 m). To assure proper
operation and maximum performance at higher
altitudes, it may be necessary to adjust the combustion
air/fuel mixture.
The best guide to proper air/fuel mixture is
exhaust color. The exhaust should always be
clear. Black or white smoke indicates an improper
air/fuel mixture:
a) If the exhaust is clear, no adjustment is needed.
b) If the smoke is dark or black, there is not enough
air in the mixture.
c) If the smoke is white, there is too much air and not
enough fuel in the mixture, or there is water in the
fuel.

Plate (removed).
If the smoke color is either black or white, follow
these steps to adjust the air/fuel ratio.
The AIR ADJUSTMENT DIAL (Figs. A, E) is located
on the side of the unit above the fuel filter.
1. Loosen bolt and rotate the shutter in the appropriate
direction:
a) A larger opening corrects for black smoke
(allows more air into the combustion chamber);
b) A smaller opening corrects for white smoke
(allows less air).
2. Tighten the dial bolt when adjustment is complete
TIP: If the exhaust remains white even after adjusting
to the smallest opening, there is probably water in the
fuel. You may need to replace the fuel filter and/or
clean the fuel tank (see Maintenance, p. 6).
NOTE: It is normal to see a small amount of smoke
when starting or stopping the unit.
Thermal overload protection
The unit is automatically protected against internal
overheating. If the internal temperature of the heat
exchanger exceeds a preset value, the burner will
automatically turn off. The blower will continue to
operate until the heat exchanger has cooled. Once the
