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.
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”.
Medium - Burn (approx. 13,000-16,000 Btu/hr.). Pull
control handle out approx. 1 1/2”.
Medium-High Burn (approx. 16,000-25,000 Btu/hr.).
Pull control handle out approx. 2 1/2”, until small click is felt.
High Burn (Maximum – approx. 44,000 Btu/hr.)
Pull control handle out to its full extended position.
WARNING: OPERATING STOVE ON HIGH FOR EX-
TENDED PERIODS WASTES FUEL, AND WILL CAUSE
A WHITE BUILD-UP (HAZE) ON GLASS AND CAN
CAUSE DANGEROUS OVERFIRING CONDITIONS.
NEVER LEAVE STOVE UNATTENDED ON HIGH.
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.
