SCREWS

WARNING: Disconnect all power coming to replace at

main service panel before attempting any maintenance

or cleaning to reduce risk of re, electric shock or

damage to persons.

WARNING: If the replace was operating prior to

servicing allow at least 10 minutes for light bulbs and heating elements to cool off to avoid accidental burning of skin.

Light Bulb Replacement

Light bulbs need to be replaced when you notice a dark

section of the ame of when the clarity is reduced. There are four bulbs under the log set which generate the ames

and embers.

Helpful Hints: It is a good idea to replace all light bulbs at one time if they are close to the end of their rated life. Group replacement will reduce the number of times you need to open the unit to replace light bulbs. Long life bulbs are recommended to reduce the frequency of bulb changes.

Bulb Requirements: Quantity of 4 clear chandelier or candelabra bulbs with an E-12 (small) socket base, 60 watt rating. Example: GE 60BC or Philips 60CTC.

Do not exceed 60 Watts per bulb.

Tool Requirements: Philips Screw Driver

Pull the rear edge of the log set forward by grasping 3.

the ember bed by the sides, pull rmly until the rear tab

pops out from under the back ledge, then lift the logs

out. (Figure 4)

IMPORTANT: Only handle the log-set by the plastic ember-bed, not the logs themselves.

NOTE: Log-set ts tightly into rebox. Some force may

be necessary to remove.

Examine the bulbs to determine which bulbs require 4. replacement.

Remove the icker rod. Begin by removing the plastic 5. grommet, which holds the end of the rod in the left bracket. Grasp and turn it ¼ turn, releasing it from the slot in the bracket, and then lift it out of the bracket.

The motor side of the rod may be attached to the motor 6. in one of two ways:

Secured with a spring - attach needle nose pliers to • the spring on the motor shaft and pull while rotating in the same direction of the spring winding. Secured with a rubber gasket - pull and twist the gas-• ket away from the motor simultaneously until it comes off the motor shaft.

CAUTION: Ensure that the icker rod does not get

bent during removal and re-connecting, ensure the rod is

straight when replaced, otherwise, it may cause excessive noise during operation.

NOTE: To replace the icker rod that uses a spring, attach needle nose pliers to the icker rod spring and push onto the icker motor shaft while rotating in the opposite

direction of the spring winding.

Unscrew bulbs counter clockwise.7.

Insert new bulbs.8.

Reassemble in the reverse order as above.9.

NOTE: To replace the log set insert the front edge, pushing back down until the rear tab snaps under the back

ledge and the logs are resting against the partially reective

glass.

Partially Reective Glass Cleaning

The partially reective glass is cleaned in the factory during

the assembly operation. During shipment, installation,

handling, etc., the partially reective glass surface may collect dust particles; these can be removed by bufng

lightly with a clean dry cloth.

To remove ngerprints or other marks, the partially reective glass can be cleaned with a damp cloth using

good quality household glass cleaner. The partially

reective glass should be completely dried with a lint free

If access to the switch side of the unit is not possible the following instructions can be followed:

i) With the small gauge wires still attached, pull the

original receiver out of the side opening as much as possible without damaging the wires, and set it inside

the replace.

ii) Cut the remaining shaft of the mounting tabs as close

as possible to the side panel of the replace.

iii) The replacement receiver is supplied factory mounted

on a new interior cover plate.

iv) VERY IMPORTANT!!! Please read the following steps

very carefully and refer to Figure 6. The small gauge

wires from both the original and the new receiver will require cutting to then be connected to its matching wire on the other receiver using the 3M push button connectors included in the package.

v) Take the new replacement receiver/plate and cut the

small gauge wires leaving approximately 8” inches in length from the new receiver.

vi) Using wire cutters, cut one of the small gauge wires off

the old receiver approximately 1” inch from the base,

Figure 6

carefully noting its location.

NOTE: It may be easier to match the wires by cutting

off the plastic wire tie which secures the 9 wires all together.

vii) Find the same wire coming from the exact same loca-

tion on the new receiver to match it up to the original wire. Colors should match each other.

viii) Using the push button wire connector, connect the

matching wires together. Pick up wire connector and

place (1) wire into each terminal; (i.e. 1 yellow wire

from the original receiver into one hole and one yellow wire from the new receiver in the remaining hole, for a total of 2 yellow wires).

ix) Secure wires in the connector by pressing/crimping

the 3M symbol on the orange plastic button with slip joint pliers or needle nose pliers. Slightly pull on end of wires to ensure there is a strong connection.

x) Repeat this process for the (7) remaining wires cutting

and matching only one color at a time, ENSURING EACH CONNECTOR HAS THE SAME WIRE COL-

ORS; (Red to Red; Orange to Orange; Blue to Blue;

etc.).

Connect all of the wiring connections to their original 13. locations on the new receiver - depending on the age of your unit there are 3 different remote control receiv-

ers that you could have see Figure 7 to determine

where the wires should be attached to ensure correct operation.

Mount the new receiver in the location of the original, 14. ensuring the proper orientation.

Re-assemble the replace in the reverse order as 15. above.

NOTE: To replace the log set, insert the front edge of the log set and pushing back down until the rear tab snaps under the back ledge and the logs are resting against the

partially reective glass.

NOTE: Once installed, ensure that the levels on the indicator lights are turning on in the correct sequence for stage 1, 2, and 3.

NOTE: Check that the replace operates in the correct

sequence: Stage 1 – Lights (No Heat), Stage 2 – Lights and Low Heat, Stage 3 – Lights and High Heat.
