a.
Existing fuel-fired equipment shows evidence of back puffing, smoke roll-out, inefficient operation, or
excessive smell in the living area.
b. Opening a window or door alleviates any of the above problems or symptoms.
c.
The building is constructed with a well-sealed vapor barrier, tight fitting windows, or has powered exhaust
fans.
d. Excessive condensation on windows in the winter.
e. The building has a ventilation system installed.
f.
If, once installed, the solid-fuel appliance does not draw steadily, burns poorly or inefficiently, back-drafts or
experiences back-puffing when adding fuel.
VENTING (DRAFT) REQUIREMENTS
The chimney flue is a critical component to the proper and efficient operation of any heating appliance. Heating
appliances do not create draft, draft is provided by the chimney. This appliance requires a draft of 0.05 in. water
column (0.1 Pa) at the flue collar.
To achieve proper draft, your chimney must meet three minimum height requirements; minimum height from
top of appliance (15 ft. total height from top of appliance), minimum height above roof penetration (3 ft.), and
minimum height (2 ft.) above highest point of roof within a 10 ft. diameter from the chimney. The chimney must
also meet minimum and maximum cross sectional requirements. For that reason a continuous 6˝ stainless steel liner
from the flue collar to the top of the chimney is required. A stainless steel adapter is recommended for fastening
the stainless steel liner to the flue collar. The male (or crimped) end of the adapter must be installed inside the flue
collar to allow condensation or creosote in the liner to drain back into the firebox. Chimney liners and/or adapters
must be permanently fastened using a minimum of three (3) screws at each connection. Chimneys outside of the
home or on an exterior wall are difficult to keep at operating temperatures and may result in increased creosote
buildup, less draft, back drafting problems and poor appliance performance and should be avoided.
FLOOR PROTECTOR
A solid non-combustible floor, concrete or solid masonry, must extend 6˝ to either side of the body of the
appliance and 12˝ in front of the face of the appliance. When combustible flooring falls within these minimum
dimensions, it must be covered with a listed floor protector meeting the requirements of UL 1618, such as Hy-C
or Imperial Model UL 2840BK or equivalent with 0.84 R-factor, 1” thick. (Note: to calculate R-value of alternative
materials see Floor Protector Material Calculations at the back of this manual.) A grouted ceramic floor tile that
meets local building codes and the minimum 0.84 R-factor requirements is considered a durable equivalent.

Minimum Floor Protector Specifications
WARNING:
RIsk of fire - do not allow combustible materials (carpet, furniture, fuels) to be placed on or cover
the floor protector. All combustible materials must remain outside of the minimum clearance dimensions.
WARNING:
RISK OF FIRE - EXCESSIVE DRAFT CAN CAUSE OVERFIRING AND A POSSIBLE STRUCTURE FIRE. DO NOT
OPERATE THIS APPLIANCE WITH THE FLUE DRAFT EXCEEDING 0.06 in. w.c. (0.1 Pa).
