To install the heater without legs as a fireplace insert, 
the floor must be completely noncombustible, such as 
an unpainted concrete floor over earth.
Many fireplaces do not satisfy the “completely non-
combustible” requirement because the brick or con-
crete hearth in front of the fireplace opening usually is 
supported by heavy wooden framing as in Figure 13.  
Because heat passes readily through brick or concrete, 
it can easily pass through to the wood. As a result, 
such fireplace hearths are considered a combustible 
floor. You may not install a heater on a combustible 
hearth without legs. Standard leg installations must 
include the bottom heat shield.
  The  floor protector 
must also meet standard requirements for freestanding 
installations.
Floor Protection for Fireplace
 Installations with Standard Legs 
Fireplace installations with the standard legs and the 
bottom heat shield must have a floor protector of the 
same construction as that specified for freestanding in-
stallations: 1/4” non-asbestos mineral board or equiva-
lent, or 24 gauge sheet metal (that may be covered with 
a decorative noncombustible material if you desire).  
The floor protector must extend at least 16” (406 mm) 
[18” / 457 mm in Canada] from the front of the stove 
and from the left (loading door) side, and at least 6” 
(152 mm)  from the right side and rear.  It must also 
provide protection beneath any horizontal runs of the 
chimney connector, including 2” to either side.
Many raised hearths will extend less than the required 
distance from the front of the heater when it is installed.  
In such cases, sufficient floor protection, as described 
above, must be added to extend the hearth 16” (406 
mm) [18” (457 mm) in Canada].
Hearth rugs do not satisfy the requirements for floor 
protection.  
Fireplace insert installations also have specific clear-
ance requirements to the side walls, side decorative 
trim, and fireplace mantel.  This information is found in 
“Fireplace Installation Clearances” in this section. 
REMINDER- FIREPLACE INSERT INSTALLATIONS 
WITHOUT LEGS ARE PERMISSIBLE ONLY IF THE 
HEARTH IS COMPLETELY NONCOMBUSTIBLE, 
SUCH AS UNPAINTED CONCRETE OVER EARTH.
Keep the Stove a Safe Distance 
From Surrounding Materials
Both a stove and its chimney connector radiate heat 
in all directions when operating.  A safe installation re-
quires that adequate clearance  be maintained between 
the stove and nearby combustible materials to ensure 
that such materials do not overheat.
Clearance is the distance between either your stove or 
chimney connector, and nearby walls, floors, the ceiling, 
and any other fixed combustible surface.  Keep  furnish-
ings and other combustible  materials away from the 
stove  as well.  In general, a distance of 48” (1220 mm) 
must be maintained between the stove and moveable 
combustible items such as drying clothes, furniture, 
newspapers, firewood, etc.  Keeping those clearance 
areas empty assures that nearby surfaces and objects 
will not overheat.  
Safe Ways To Reduce Clearances 
Your stove has specific clearance requirements that 
have been established through careful research and 
testing to UL and ULC standards.
Clearance requirements have been established to meet 
every installation possibility, and they involve the combi-
nation of basic variables: 
 
 
• 
When the stove has no listed heat shield  
• 
When the stove has a listed heat shield  
• 
When the wall has no heat shield 
• 
When the wall has a heat shield  
• 
When the stove has a double-wall chimney con-
nector.
• 
When the stove has a single-wall connector 
wit heat shields, or without heat shields.
In general, the greatest clearance is required when you 
locate a stove with no heat shield near a wall with no 
heat shield.  The least clearance is required when both 
the stove and the wall have heat shields.  Reducing a 
stove clearance may require a listed heat shield on the 
chimney connector as well, or a double-wall connector. 
Clearances may be reduced only by means approved 
by the regulatory authority and in accordance with the 
clearances listed in this manual. The charts and sample 
installations that follow list all the clearances required 
for the various installation configurations of Dutchwest 
Convection Heaters.
