Overview
The DaVinci fireplace has been programmed to have the power exhaust fan purge the
firebox when power is introduced to the unit. This purge will last 6 minutes. You do
not have to wait for the purge to end to start the fireplace. The purge process will
occur after the initial power up and after any power outage.
The fireplace controls consist of a power distribution control board (PDB) and a base
Integrated Fireplace Control (IFC) in addition to the power exhaust fan. Additionally,
there are intake damper(s) and an exhaust damper that is controlled by the PDB.
When the fireplace is turned on there is a 10-second delay followed by a 30-second pre-
purge. The Flame Icon LED on newer TouchSmart® Wall Controls (TS) will pulse for
approximately 50 seconds to show that the unit is in start-up mode. During the delay, the
exhaust and intake dampers open followed by the power exhaust fan. During the pre-purge,
the draft produced by the power exhaust fan will activate an air pressure switch (APS)
signaling to PDB that the fan is operating. After the pre-purge, the IFC will send the signal to
initiate the start-up sequence.
The pilot and burner for this fireplace function the same as with all other GreenSmart™ 2
(GS2) appliances.
A rheostat controls the speed of the power vent. For 30 seconds the rheostat is bypassed
sending line voltage to the power exhaust fan. After the purge, the PDB sends the power
through the rheostat lowering the speed of the power exhaust fan to normal operating speed.
When the fireplace is turned off the burner and pilot turn off. The power exhaust fan,
intake, and exhaust dampers remain engaged for 6 minutes (post-purge). After post-purge the
power exhaust fan turns off, the intake and exhaust dampers close, and the APS switch opens.
The dampers will remain closed until a start sequence is initiated or if power is lost and
reinstated (goes into pre-purge then to ready state). In the event of a power failure, the
exhaust damper will fail “OPEN”.

Sequence of Operation - Flow Chart
DaVinci Troubleshooting
The DaVinci Fireplace is different from a naturally vented appliance, there are several processes that take place
simultaneously. This is important to remember when troubleshooting these fireplaces. When the fireplace is
switched on or the call for flame is made, these (3) things happen almost simultaneously:
1) Exhaust damper opens
2) Intake damper opens (if installed)
3) After 10 seconds the Power Exhaust Fan starts
Next, the APS activates and approximately 40 seconds after the call for flame the rheostat takes control of the
exhaust fan.

b. Is the main power switch turned off?
XMF Fuse c. Is there a service switch on the main power line? Is it on?
d. Is the unit wired correctly? (Incoming power to power in, not power to
power vent)
Ready Light
e. Check the transformer fuse (labeled XMF) on the
PDB (see #1 on Diagram A, on page 18). Replace as needed (1 amp) f. Check
input power to the transformer- Line Voltage
g. Check output voltage from the transformer - 24 VAC

e. Check fuses on PDB labeled “FAN” or “REO”. Replace as needed (6.3
amp SLO-BLO).
f. Check voltage to the Power Exhaust Fan - Should be Line voltage during
purge.
g. What color is the LED in the center of the PDB?
Green = Ready
Yellow/Orange = Call for Flame
Red = Fault
No light = No power or dead PDB, blown transformer fuse, or bad AC
transformer.

a. Check fuses labeled ODAM & IDAM on the PDB (see diagram). These
fuses are in series so a problem in either the intake or exhaust damper
circuits could cause a fuse to blow. Replace as needed (1 Amp).
b. Verify the damper blade operation. Check for obstruction in the vent
blocking the damper blade.
c. Disconnect the square Molex connector from the interior side of the
electrical junction box. Check continuity between the RED and BLACK
wires to the exhaust damper. If no continuity either the exhaust damper is
closed, broken, damaged wiring, or the microswitch is bad. Jump the RED
and BLACK wires and try starting the fireplace. If the fireplace operates
properly the problem is outside the firebox. See the list of possible causes
below*.
*OTHER POSSIBLE CAUSES

continues check
intake/exhaust damper
fuses and replace them
as necessary. If the
fuses are
okay, disconnect the intake damper wires (even if there is no intake
damper in the system). If the fault goes away the problem is in the intake
damper wires.
Intermittent operation with 0-DAM Fault generally means a loose
connection in the junction box of the Exhaust Fan/Damper or a loose pin
in a Molex connection somewhere in the Exhaust Damper wiring harness
circuit.

d. Check for cracked, kinked, or missing hose from APS to copper tubing.
e. Check for blocked or damaged copper tubing in the flue.
f. Did copper tubing get inserted into venting above “T” or Plenum (if
applicable). Not into flue collar? Is copper tubing kinked?
APS Light g. Is the APS light on and is there is a green “ready state” light or red fault
light or is just the red APS light on? The APS is sensing a draft when there
is not supposed to be a draft. In other words, the fan is on when it should
not be.
h. Check continuity on the yellow and blue wires between the PDB and the
APS. Replaces spades as needed.
i. Check for 5 VDC - yellow and blue wires to APS and at PDB
a. Are there lights on the PDB? (If not see the first section)
b. Is the exhaust damper opening?
c. Is the damper blade obstructed?

e. Check voltage to the intake damper – 24 VAC. If the voltage is not correct,
look for damage to the wires (for example a nail or staple through the
harness).

Other Possible Causes).
If the transformer fuse continues to blow after being replaced there is
probably a short in the exhaust damper or intake damper wiring.
Is the Transformer Fuse blown? Disconnect both harnesses, replace the fuse, and then plug either one
back in. If the fuse blows, the problem is in that circuit. If the fuse doesn’t
blow, repeat with the other circuit.

a. PRE-TOUCHSMART - Check voltage at the on/off switch. 5VDC. If no
voltage present the Over Heat snap disc has opened or failed.
TOUCHSMART - Is the flame icon lit? If yes, check the AUX. board for a
green light indicating a call for flame. Check the “Ready” light on the PDB.
If the “Ready” light is GREEN and the “Flame Relay” light on the AUX.
Does the unit burn normally and Board is lit, check continuity of the RED wire between the 2 boards. No
then suddenly shut down continuity = check the snap disc.

f. Can you turn the rheostat up to increase the fan speed?
a. Is there a green LED light on the LED power supply/ transformer? If no
check incoming power to the unit and transformer.
b. Check the voltage out of the transformer – black and white wire 24 VDC.
Do the LED lights work? c. Check voltage at the wall switch? Heavier gauge Red and Black wires – 24
Slide Controls? VDC
d. Check voltage from lighter gauge wire between BLACK and RED, BLUE,
