DRT4000 Series Direct-Vent Gas Fireplaces
If the millivolt fireplace is equipped with an optional remote switch (wall switch, remote control, rocker switch, or
wall thermostat) and the pilot is lit, the fireplace main burner can be turned ON/OFF using the optional switch.
NOTE: Do NOT wire more than one valve to the burner control switch. This will help prevent excessive resistance in
the burner circuit, that can cause burner operation problems.
Electronic Fireplaces
Detailed lighting instructions are found on Pages 67-68. Also, electronic fireplace lighting instructions are found on
the pull-out lighting instructions attached to the gas control valve.
If the electronic fireplace is equipped with an optional remote wall switch or remote control, the fireplace main
burner can be turned ON/OFF with the wall switch or remote control.
If the electronic fireplace is not equipped with a wall switch or remote control, the main burner must be turned ON/
OFF with a gas control switch installed separately. Contact the installer for more information. Check the batteries, if
installed, at least every three (3) months to ensure they are properly charged.
To light the fireplace in a power outage:
1. Confirm that batteries are installed battery pack in the control
2. Set the unit-mounted switch, or wall switch in the control
3. The unit should spark at the pilot and light.
4. Operate the fireplace normally.
Installing the Backup Batteries
With a battery backup, electronic fireplaces can automatically switch to battery power. In the event of a power outage, this
allows ON/OFF operation (without blower functionality). Install new batteries before every burn season.
1. Open the control compartment (Page 51), and locate the battery holder.
2. Install four (4) AA batteries in the battery holder.
3. Close the control compartment door.
Continuous Pilot Ignition Switch (located in the control compartment)
Fireplaces with an electronic gas valve have a continuous pilot ignition (CPI) switch installed in the control
compartment.
This switch allows the pilot to be switched from intermittent mode to continuous mode:
•
•
In periods of extreme cold, condensation may form on the glass door when the fireplace is OFF and the pilot is in
intermittent mode. Also, with the pilot in intermittent mode, the fireplace may cycle startup (i.e., the pilot and burner ignite,
but the burner extinguishes and reignites several times until the flue reaches the temperature for proper drafting).
•
•
NOTE: Continuous mode is indicated by a pilot that comes ON and remains lit when the fireplace is OFF.
Installing the Firebox Liners
1. Remove the three (3) optional firebox liner panels from the packing materials if purchased.
2. Carefully position the rear panel, upper edge first, in the firebox against the rear wall.
3. While holding the rear panel, carefully position the left side panel in the firebox.
4. Carefully position the right side panel in the firebox.
NOTE: Do not force the panels. Excessive force may cause breakage. If the panels are correctly positioned, they will fit snugly in
place.

compartment to the ON Position.
NOTE: If there is no spark, replace the batteries.
Intermittent Mode—The pilot is extinguished when the fireplace is OFF.
Continuous Mode—The pilot stays ON when the fireplace is OFF.
To save energy—switch to intermittent mode.
For a standing pilot that will help prevent glass door condensation and cycle startup—switch to continuous mode.
