SECTION I
INTRODUCTION
Your new MODEL 74 is a non-catalytic unit designed to meet the most stringent emissions
standards without the use of a catalytic combustor. This effect is achieved through the use of
secondary air which is mixed with primary air in the unit’s firebox. For peak performance,
we suggest the use of hard seasoned natural wood, loading wood length way from front to
rear. You should not burn trash or garbage, artificial or paper logs, gift wrapping,
treated or painted wood or any type of coal.
The primary air, which is controlled by the user, burns the wood. Secondary air is admitted into
the firebox through the secondary air tubes at the top of the firebox. This secondary air burns
the impurities in the smoke released from the initial wood burning. The temperature necessary
for this combustion is maintained through the firebrick refractory. If any more technical
information is necessary, contact your local dealer.
Under specific test conditions this heater has been shown to deliver heat at rates ranging from
approximately 11,800 to 40,900 BTU/HR.
These unit may also be used with optional room air blower. To order optional motor assembly
you must specify the stove model number and give the following part number:
*Model 74 Motor Assembly—MA 5126715
For operation and use of this electrical assembly, see instructions provided with the motor
assembly kit.
