Heater Assembly Replacement - Dimplex DF2608 Service Manual

! NOTE: If mounting studs are damaged, replacement
mounting studs will need to be inserted from
underneath the Log Set Assembly. Follow steps 1 - 6 of
Mirror Replacement procedure on page 9 to do this. It
is recommended to attempt to release the control board
without cutting mounting studs.
5. Properly orientate the replacement Log Driver board
and push it onto the four (4) mounting studs until the
clasps of the mounting studs snap the control board
into place.
6. Disconnect one of the wire leads from the original
control board (which are still connected to parts
within the firebox) and immediately connect it to the
new control board's terminal, matching its position.
Continue with the remaining wires (there are four (4)
wires which are piggy-backed together in pairs, and a
single grey wire) using the same procedure.
CAUTION: Internal wiring and colors may not be the
same within the unit being serviced as those shown. To
avoid damage to the unit, damage to property or
personal injury, ensure wires are reconnected to match
their original locations.
7. Follow steps 1 through 3 in reverse order to re-
assemble the firebox.
! NOTE: When placing bottom panel back onto unit,
position the metal lip from under the control panel
between the rubber spacers (attached to the bottom
panel) and the sheet metal of the bottom panel.

Heater Assembly Replacement

If the fireplace was operating prior to servicing allow at
least 10 minutes for light bulbs and heating element to cool
off to avoid accidental burning of skin.
Disconnect power before attempting any maintenance or
cleaning to reduce the risk of electric shock or damage to
persons.
Replacement Procedure
1. Remove the firebox from the mantel.
2. Remove the 10 Philips screws that fasten the top cover
to the rest of the firebox. There are: (four) 4 screws at
the back of the firebox, along the top; two (2) screws on
each side and at the top of the firebox; and two (2)
screws on the top of the firebox (Figure 18).
4. Flip the top panel over and place upside down on the
top of the unit. You may experience some resistance
as the Heater Assembly is mounted to the top panel
and may be a snug fit inside the firebox. Orientate
yourself with the placement of the Heater Assembly
and wiring as shown in Figure 19.
5. Turn the top panel over and, while supporting the
Heater Assembly and panel in one hand, remove the
five (5) Phillips heater mounting screws, noting the
center screw is of a larger diameter (Figure 20).
