DRT4000 Series Direct-Vent Gas Fireplaces
Burn-in Period
The first few times this fireplace is operated, there will be an odor from the curing of paint and the burning off of the
lubricants used in the manufacturing process. Depending on usage, the burn-in period may take a few hours or a few
days.
NOTE: Ventilate the site during the burn-in period. The resulting odor and haze may set off a smoke detector. Do not
operate the blower during the burn-in period.
A white film may develop on the glass front during the first few fires as part of the burn-in period. The glass
should be kept clean during the burn-in period to prevent the film from baking on—making it very difficult to
remove (Cleaning the glass door on Page 58).
Accessing the Control Compartment
Opening the Control Compartment Door
1. Grasp the top of the control compartment door and gently pull it to release the door from the magnet. Lower the
door until it stops (see Figure 42).
Closing the Control Compartment Door
1. Swing the control compartment door gently up until the magnet engages the door in the closed position.
Removing the Control Compartment Door
1. Open the lower control compartment door (see instructions above).
2. Remove the control compartment door by sliding the hinge pin, located at the door's left side, to the right until it
disengages from the left corner post hole. Pull the door diagonally to the left, away from the fireplace (see Figure 42).

Gas Controls
The standard controls for fireplace operation are located in the control compartment, below the glass door (Page
40). Optional control switches are also available.
Millivolt and electronic gas control systems operate differently. Before lighting and operating the fireplace determine
if it is a millivolt or electronic system:
•
Millivolt Fireplaces (Figure 1, Page 9)
•
Electronic Fireplaces (Figure 2, Page 9)
Familiarize yourself with the gas control valve and the lighting procedure Pages 65-68.
Millivolt Fireplaces
Detailed lighting instructions are found on Pages 65-68. Also, millivolt fireplace lighting instructions are found on
the pull-out lighting instructions attached to the gas control valve.
When the pilot is lit, the main burner can be turned ON/OFF using a wall switch, remote control, optional on-unit
rocker switch (FRS), or wall thermostat.
