Hearthstone Maidstone DVI HT

Hearthstone Maidstone DVI HT

Imagine your fireplace – the focal point of any room, where friends and family just naturally gather around – made even more efficient by adding a Maidstone Direct-Vent insert. Gas-fired and designed to fit perfectly into your fireplace, the Maidstone features a double heat exchanger that allows less heat up the chimney, more into your home. Adjust the flame height upwards, and the Maidstone will keep you warm and comfortable. Or, adjust it down – and enjoy a gentle warmth along with a beautiful flame display.


Certified room heater

Increased stove efficiency; less heat lost up the chimney results in more usable heat for less money.

Millivolt ignition system

Stove can operate without electricity; excellent source of heat during power outages.

Wall thermostat

Thermostat turns stove on and off; maintains the home at preset comfort level; desired heat is maintained automatically. Optional programmable thermostat is also available.

Two-speed blower

Heated air is moved throughout the home for more uniform temperature. Thermostat monitors stove body temperatures and automatically turns the fan on or off. You set the speed of the fan.

Three-way on/off thermostat switch

Allows you to flip the stove on for instantaneous fire or to control the stove from the wall thermostat or to turn it off.

Adjustable heat output

All the pleasures of fire viewing ambiance, even when little room heat is desired.

Remote controls (optional)

Simple “on/off” remote control and thermostatic remote control allow the fire to be controlled from across the room. Temperature is controlled by the thermostat located within the remote itself.

Firebox screen kit (optional)

Enhances flame and reduces hearth requirement. The door glass “disappears” from viewing, leaving only the dancing flames and glowing logs.
