A fresh air kit enables you to use outside air, instead of room 

air to fuel the fire. Using an outside source for combustion air 

has its advantages. If your home is tight and well insulated, 

then the fire in the stove may be “starved” of combustible air, 

it will be difficult maintaining a fire, and you may have back 

drafting problems.

During the heating season, cold air, (which is more dense than 

warm air), will cause the fire to burn a little hotter, resulting 

in more BTU’s from your wood, and less creosote build-up.

Mounting holes and airways are all pre-punched on all new 

Oval and Sweetheart cookstoves.(See figure 5)

Simply remove the cover plates (right side of firebox on the 

Oval and, bottom of the firebox on Sweetheart). Now you 

are ready for installation. A complete set of diagrams and 

instructions are included with each fresh air kit.

Please note that some States require a fresh air source to be 

installed with wood burning appliances. Please check your 

local, and state, building codes.

              

The average family spent about one quarter of their utility 

bill to heat water last year. By installing the water jacket in 

your cookstove, you can reduce or virtually eliminate your 

hot water utility bill.

The water jacket can be installed in the stove in less than a 

minute using only a slot screwdriver. The water jacket is a 

hollow baffled chamber that fits in the firebox. Two pipes and 

a pump installed from the water jacket to the electric or gas 

water heater, circulate heated water from the stove to the 

storage tank. (See illustration, Fig. 6.)

You can expect from 8 to 10 gallons (30.3 to 37.9L) or more 

hot water per hour (about 10,000 BTUs) from your oval water 

jacket, OR 6 to 8 gallons (22.7 to 30.3L) (about 8,000 BTUs) 

from your Sweetheart water jacket. 
Because  cold  water  cools  the  water  jacket  in  the  firebox, 

creosote will be attracted to its cool surface, like humidity being 

attracted to a cold window. These deposits will quickly burn off 

thus reducing creosote formation in the stove and chimney.
An installation and operating manual is packed with every Oval 

and Sweetheart water jacket. Extra copies may be obtained 

from your dealer or by contacting AGA Marvel.
