Operation

Figure 1

General Operation

WARNING: This electric firebox must be properly in-

stalled before it is used.

This firebox operates with Comfort$aver

technology,

which automatically adjusts the fan speed and heater watt-

age to safely and precisely match the requirements of the

room based on the thermostat setting. The heater operates

such that once the room reaches the set point, the fan and

heater will continuously run at a low level, to maintain the

desired room temperature. If the temperature in the room

rises significantly, i.e. sun coming through a window or a

central furnace turns on, the heater will turn off and periodi-

cally turn back on to circulate the air around the unit, until

the room temperature drops and requires the heater to be

constantly on again.

NOTE: The unit is designed so that the fan will run con-

tinuously while the heater is on.

NOTE: The element retains heat after shutdown, there is

a built in cool down period of 2 minute before the fan shuts

off completely, when the heat function is turned Off.

Remote Operation

The replace is supplied with an IR multi-function remote

control.

NOTE: To operate correctly, the remote control must be

pointed towards the front of the unit.

Controls

The unit can be controlled by either the manual controls

which are located on the upper right of the replace or the

remote (Figure 1 & 2).

A. Standby

Turns the unit On and O.

→ Activated by pressing the Standby button on the remote

or the unit.

• The unit will turn On with the same functions that it was

set to when it was turned O and the intake temperature

will be indicated on the Display.

NOTE: When any button is pressed on the unit the

intake temperature will be displayed on the Display for 7

seconds.

→ Activated and adjusted by repeatedly pressing the cor-

responding button on the remote.

• Indicated by the heater running at full heat, for a user set

amount of time, to quickly heat up a cold room/space.

The Heat Boost can be set for a maximum of 20 minutes,

in 5 minute increments.

Disable Heat

If desired, depending on the season, the heater on the unit

can be disabled. The function of the remaining controls will

continue to function as outlined in this manual.

Pressing the

and buttons on the unit at the same

time and holding for 2 seconds will disable and enable the

heater.

NOTE: When the heater has been disabled and any of

the heat related functions are used, the Display will indicate

“---”.

H. Color Themes

Dierent presets of lighting color combinations are avail-

able in the unit.

→ Changed by repeatedly pressing the corresponding but-

ton on the remote or the unit.

• Cycles through the dierent preset light settings of the

NOTE: The Sleep Timer can be cancelled at any time

by pressing the button repeatedly until the sleep timer

displays nothing.

Resetting the Temperature Cuto Switch

Should the heater overheat, an automatic cut out will turn

the whole unit o and it will not come back on without being

reset. If the

button on the unit is pressed, Er2 will be

Figure 2

displayed on the unit. It can be reset by turning the unit o

at the main disconnect panel and waiting 5 minutes before

turning the unit back on.

CAUTION: If you need to continuously reset the heater,

turn the unit o at the main disconnect panel and call tech-

nical support at 1-888-346-7539.

Maintenance

 WARNING: Disconnect power and allow heater to

cool before attempting any maintenance or cleaning to

reduce the risk of re, electric shock or damage

to persons.

NOTE: The replace should not be operated with an

accumulation of dust or dirt on or in the unit, as this can

cause a build up of heat and eventual damage. For this

reason the heater must be inspected regularly, depend-

ing upon conditions and at least at yearly intervals.

Partially Reective Glass Cleaning

The partially reective glass is cleaned in the factory dur-

ing the assembly operation. During shipment, installation,

handling, etc., the partially reective glass may collect dust

particles; these can be removed by dusting lightly with a

clean dry cloth.

To remove ngerprints or other marks, the partially reec-

tive glass can be cleaned with a damp cloth. The partially

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

cloth to prevent water spots. To prevent scratching, do not

use abrasive cleaners.

Fireplace Surface Cleaning

Use only a damp cloth to clean painted surfaces of the

replace. Do not use abrasive cleaners.

Servicing

Except for installation and cleaning described in this manu-

al, an authorized service representative should perform any

other servicing.
