OPEN VALVE DOOR ON THE CENTER
BOTTOM OF THE FRONT FOR ACCESS TO
ELECTRICAL AND GAS CONNECTIONS
Electrical Grounding Instructions
This appliance is equipped with a three-prong
(grounding) plug for your protection against shock
hazard. Use only a properly grounded three-prong
receptacle. Do not cut or remove the grounding
prong from this plug. Place the receptacle to the
right of, or behind the unit.
Switch Plate
The DVI-Ht comes pre-wired to the control switches.
To install, use the two 10-24 x ½” screws to mount
the plate to the left surround panel. The plate will fit
in the recessed side of the surround.
Thermostat
The fireplace insert is operated by the
on/off/thermostat switch. You can control the DVI-Ht
automatically with the provided wall mounted
thermostat. We recommend installation of the
thermostat for a more comfortable, automatic
performance; however you can still override the
thermostat by setting the switch to “on”. The
thermostat controls the unit by “calling for heat.” The
thermostat turns the unit on when the room is cold,
and turns the unit off once the room is warmed
sufficiently. The thermostat is controlled by a 750
millivolt DC, two-wire circuit. The thermostat comes
with 40' (12m) of thermostat wire.
Thermostat Wiring
The thermostat wire from the unit to the thermostat
can be surface mounted, routed under the floor, or
through walls, etc. Connect the thermostat to the
unit using no more than the 40' (12 m) of insulated
thermostat wire provided. Ensure you leave a small
coil of wire behind the unit so that it can be moved
out of position for servicing and cleaning.
Thermostat Placement
Place the thermostat in the same room or living
space as the unit. Typically 5' (1.5 m) off the floor
and away from any influences that may cause the
temperature in the vicinity of the thermostat to be
unrepresentative of the room temperature in
general. Such influences might include strong
lighting, a heater vent from the central heating
system, or a nearby drafty window. Placement of the
thermostat on an inside wall rather than an outside
wall is preferable. Do not place the thermostat
directly over, or too close to the unit, otherwise heat
from the unit will immediately satisfy the thermostat
and turn the unit off.
Wiring Instructions
The valve post connections are found by opening
the bottom center grill on the front of the unit. Also,
refer to
Figure 8 w
hen making these connections;
position the thermostat wire so it extends out the
side surround panel towards the thermostat. (At the
thermostat, connect the wires to the two connection
screws on the back of the thermostat per the
instructions received with the thermostat. Take care
not to over-tighten the connection screws and not to
damage the internal parts of the thermostat. Now
attach the wires in their proper location on the
firebox.
