DVI 44 8860 Model Overview

Proflame 2 GTMFS System

The Proflame 2 GTMFS is a modular remote control
system that directs the functions of the DVI 44. The
Proflame 2 GTMFS System is configured to control
the on/off, main/split burner operation, its flame
levels, and provides Manual and Smart thermostatic
control of the hearth appliance. The system controls
two remotely actuated 120V/60Hz power outlets. The
Fan outlet controls the fan speed through six levels,
and the Auxiliary outlet, used for the firebox light,
either on or off. There is also an additional constantly
powered 120V/60Hz outlet. The system has battery
backup power for burner operation and control during
power outages (see page 13 for specifications).

Back-up Battery Holder- On/Remote/Off
Switch

The back-up battery holder is powered (6V DC) by
the Control Board and uses four 1.5 volt AA type
batteries for backup during power outages. The slider
switch is set to one of three positions: ON (Manual
Override), REMOTE (Remote Control) or OFF. The
ON selection turns the valve on (to high), and
activates the split flow setting last used if the Remote
becomes inoperative.

Figure 4 – Proflame 2 Battery Holder

Figure 3 – Proflame 2 Remote Transmitter

Remote Transmitter

The DVI 44 comes equipped with a thermostatic
remote control transmitter. The easy to read LCD
display shows all functional abilities as well as a
childproof lockout and low battery indicator. It
displays room temperature readout, set temperature
readout and function status. The remote transmitter is
powered by three 1.5 volt AAA batteries. A Mode Key
is provided to index between the features and a
Thermostat Key is used to turn on/off or index
through thermostat functions.

Figure 5 – Proflame 2 Control Board

Proflame 2 Control Board

This is the command center for the appliance. The
Control Board allows the pilot to run in the
Intermittent (IPI) mode or the Constant (CPI) mode.
The pilot mode can be toggled between IPI and CPI
via the remote control. The Control Board signals the
burner to light or shut down and provides the ignitor
with the electricity needed for sparking. It is the main
power supply for the entire system when 120V power
is available or by the batteries in the Back-up Battery
Holder during a power outage.

The Control Board provides 120V power to control
the fan unit through 6 speeds and turns the Accent

Hearthstone Quality Home Heating Products, Inc. DVI-44 Model 8860

12

Light on and off via the remote control. Neither the
Accent Light nor the blower will operate when 120V
power is not present.

The Control Board is equipped with a three-prong
(grounding) plug for protection against shock hazard
and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or
remove the grounding prong from the plug.

SIT Modulating Gas Valve

The remote transmitter can modulate the valve and
the flame to 6 different settings between high and off.
You can modulate the flame via the remote yourself
or by setting the remote control to one of the
thermostatic modes. In the thermostatic mode, the
stove will turn on/off based on the temperature set on
the remote. In the Smart thermostatic mode, as the
room temperature approaches the limit set for shut
down the valve will automatically gradually step down
the flame height. The reverse happens when the
room cools - the valve will automatically gradually
increase the flame height.

SIT Split Burner Solenoid

The remote transmitter can toggle between dual
burner, and single burner mode (46,000 Btu/hr (LP)
43,000 (NG) or 16,000 Btu/hr). The burner will turn
on/off.

Pilot Assembly

The pilot assembly consists of a pilot hood, sensor
rod, and ignitor. The ignitor sends a spark to the pilot
hood which ignites the gas and lights the pilot. With
the pilot lit the sensor rod is engulfed by the flame,
flame rectification occurs and the appliance remains
lit. If the sensor does not stay engulfed by the flame
the main burner will not light and the pilot will shut
down.

Control Functions

Pilot Mode

Continuous Pilot (CPI): Running the DVI 44 in CPI mode will keep your pilot on even when the thermostat
does not call for heat and when the burner is not lit. This is an advantage in cooler temperatures or under windy

conditions. The “standing pilot” helps to keep the venting warm and generate some draft within the system. The

standing pilot also keeps the firebox and venting warm – greatly minimizing, draft issues or condensation
formation on the glass during startup. The ignitor will automatically spark whenever the pilot mode is switched to
CPI, regardless of the position of the receiver switch. Hearthstone recommends the use of the CPI mode during
the heating season.

Intermittent Pilot (IPI): Using the IPI mode is a more efficient use of fuel as the pilot only ignites when the
thermostat calls for heat.

To switch back and forth between the two pilot modes 1) Press the OFF button on the remote 2) Press the
Mode button on the remote. 3) Press Up or Down on the center pad to toggle back and forth between the two
modes.

Back –up Battery Holder- On/Remote/Off Switch

The Back-up Battery Holder is normally powered by the Proflame 2 Control Board or by four 1.5V AA batteries
during a power outage. This On/Remote/Off switch can be set to three different positions:

On: Manual override allowing the valve to function and ignite the burner without the remote transmitter. The
ignitor will spark automatically.

Remote: Remote Transmitter controls all functions of components.
Off: Turns off the stove. If CPI mode is selected, pilot will remain lit.
PRG Key: Used to synchronize the Transmitter and Receiver initially, and after each battery change (see page

38).
