Lennox Hearth T300HT Provide Adequate Air For Combustion, Use Control Settings That Work For You

CARE AND OPERATION

PRIMARY AIR CONTROL

The Model T300HT has one combustion air control lo- cated under the ash lip.

Start-up:To provide sufficient combustion air to achieve a clean burn as quickly as possible, the T300HT has the ability to supplement its primary air with extra "Start-Up" air. This is achieved by pulling the air control rod all the way out, and should only be adjusted to this setting when starting a fire, when refueling or otherwise for short dura- tion’s only.

CAUTION: OPERATION WITH PRIMARY AIR CON- TROL IN "START-UP" POSITION (PULLED ALL THE WAY OUT) FOR EXTENDED PERIODS, WASTES FUEL AND CAN CAUSE DANGEROUS OVERFIRING CONDITIONS. NEVER LEAVE STOVE UNATTENDED ON HIGH SETTINGS.

Positions

Adjusting Burn Rate: The primary air control handle can be pulled out to the open position for higher temperatures and moved in to a more closed position for lower tem- peratures.

IMPORTANT: Push air control all the way in (closed) before pulling rod out to set desired burn rate. This clears the high burn control plate so it is not left open.

Generally, you will want to set the air control somewhere in the low or medium range.

Low Burn - (approx. 9,000-13,000 Btu/hr.). Pull control handle out approx. 3/4”.

PROVIDE ADEQUATE AIR FOR COMBUSTION

In well insulated and weather tight homes, it may be diffi- cult to establish a good draft up your chimney. The poor draft is caused by a shortage of air in the house. To pro- vide the needed air, crack a window on the windward side of the house.

USE CONTROL SETTINGS THAT WORK FOR YOU

The fuel, the amount of heat you want, the type of instal- lation you have and how long you wish the fire to burn are all variables that will affect the control setting. The same control settings in a variety of installations will produce different results.

Familiarize yourself with your stove by trying different set- tings so you can learn how much heat to expect and how long the fire will burn. It may take a week or two to learn but your patience will be rewarded by the warmth and pleasant satisfaction that only a wood fire can provide.
