INTRODUCTION

Thank You for your purchase of a Vogelzang Wood/Coal 
Burning Gravity Style (Up-Flow) Furnace. Your decision 
to buy our Furnace was undoubtedly reached after much 
careful thought and consideration. We are very proud you 
chose this furnace and trust you will receive the comfort 
and economy that others realize when heating with a Vo-
gelzang product.
Your dealer is important in your experience with the fur-
nace not only with the purchase, but for recommendations 
for professional installation in your home. The quali

fi

 ed 

professional installer has been expertly trained in solid-
fuel furnace installation to assure the safety and comfort 
for your family while saving you money. 

IMPORTANT

Before installing and using your furnace, please read the 
following pages thoroughly and carefully. If you follow the 
instructions, your furnace will give you safe and more de-
pendable service for years to come.

•  First step: Check your local codes. This installation 

must comply with their rulings.

•  Do Not install this furnace in a mobile home or trailer.• 

Always have a smoke or ionization detector and a CO 
detector installed in your home.

•  To prevent injury or damage, do not allow anyone who 

is unfamiliar with the furnace to operate it.

•  This furnace must be installed ONLY in the prescribed 

manner shown in illustrations 1, 2, or 3 under the In-
stallation Examples in this manual. It is NEVER to be 
installed as a counter-

fl

 ow or down-draft furnace, or 

in any manner wherein the heated air is directed in a 
downward 

fl

 ow into the home or toward to an existing 

central furnace.

•  NEVER INSTALL outside the home.
•  Spend adequate time with your furnace to become well 

acquainted with the different settings and how each 
will affect its burning patterns. It is impossible to state 
just how each setting will affect your furnace because 
of the variations in each installation.

DISCLAIMER NOTICE

The BTU ranges and heating capacity speci

fi

 cations  are 

provided as a guide and in no way guarantee the output 
or capacity of this unit. The actual BTU output depends 
on the type of fuel being burned and its conditions, the 
thermostat setting, the draft adjustment and the chimney 
to which the unit is attached. The actual area that this unit 
will heat depends on factors such as the conditions of the 
building, heat loss, type of construction, amount of insu-
lation, type of air movement, the location of the unit and 
more importantly the duct work and return air facility.

Warning:

Do not alter this appliance in any way other than speci

fi

 ed 

in these instructions. Doing so may void your warranty.

LOCATING YOUR FURNACE

The furnace is to be installed maintaining the clearances 
speci

fi

 ed in the following illustrations.

Do not place the furnace directly on a combustible 

fl

 oor. If 

you are placing it on a combustible 

fl

 oor, an approved 

fi

 re 

retardant material, equivalent to 3/8” UL Listed millboard, 
measuring 41 x 72 should be placed under the unit. The 
material must extend at least 16 inches beyond the front 
of the unit and 8 inches on either side of the fuel loading 
door opening. It must also extend underneath the chimney 
connector and to each side of the connector by at least 2 
inches.

CLEARANCES

REDUCED CLEARANCES

NFPA guidelines and most codes permit reduced clear-
ances to combustible walls and ceilings if adequate pro-
tection is added. A common mistake is to assume that 
sheet metal, masonry, or millboard placed directly against 
a wall protects it. Materials installed in this manner actually 
provides very little protection. These materials are good 
heat conductors, so they will be almost as hot on their 
back side as they are on the exposed side. Therefore, the 
combustible wall behind is still a 

fi

 re hazard.

A wall can be kept cool using these items but only if they 
are mounted and spaced out from the wall by an inch or 
two to allow free air circulation behind the protective panel. 
The protective panel should also have a gap between the 

fl

 oor and ceiling.

Three rules to follow when constructing wall protectors:

1.  Non-combustibility of all materials including mount-

ing and supporting.
