Installation  
Questions To Ask Local Building Official  
A correct installation is critical and imperative for reducing fire hazards  
and perilous conditions that can arise when wood burning appliances are  
improperly installed. The installer must follow all of the manufacturers’  
instructions. These models are designed as radiant room heaters and  
should be used for no other purpose.  
Care and Operation  
Recommended Fuel / Wood Storage  
Maintenance  
Troubleshooting  
The installation of a wood burning appliance must conform to local codes  
and applicable state and federal requirements and a building permit must  
be obtained before installing. Familiarity with these requirements before  
installation is essential. Important considerations to discuss with local  
building officials include:

cient, dependable installation for your appliance and vent system.  
Smoke Detectors  
PLEASE READ AND UNDERSTAND THESE INSTRUCTIONS  
BEFORE BEGINNING YOUR INSTALLATION  
Since there are always several potential sources of fire in any home, we  
recommend installing smoke detectors. If possible, install the smoke  
detector in a hallway adjacent to the room (to reduce the possibility of  
occasional false activation from the heat produced by these appliances).  
If your local code requires a smoke detector be installed within the same  
room, you must follow the requirements of your local code. Check with  
your local building department for requirements in your area.  
TESTING / LISTING  
Models CI1000HT and CI2000HT have been Listed to UL Standard #1482  
and ULC-S627 by OMNI-Test Laboratories, Inc.; Beaverton, OR; Report  
numbers; CI1000HT #132-S-03-2 and CI2000HT #132-S-05-2.  
Installation / Solid Fuel Standards  
National Fire Protection Association – The primary NFPA standard that  
refers to installation and maintenance of wood fired appliances and  
venting is NFPA 211 – Latest Edition: Chimneys, Fireplaces, Vents, and  
Solid Fuel appliances.  
EPA (Environmental Protection Agency)  
This heater meets EPA particulate matter (smoke) control requirements  
for noncatalytic wood heaters built on or after July 1, 1990.  
Note – This appliance is NOT approved for installation into a Manu-  
factured Home.

SELECTING A LOCATION  
CAUTION  
The design of your home and where you place your stove will determine  
its value as a source of heat. This type of appliance depends primarily on  
air circulation (convection) to disperse its heat, and therefore, a central  
locationisoftenbest.Thereareotherpracticalconsiderations,whichmust  
be considered before a final selection of locations is made.  
The body of these appliances are very heavy. The  
use of a heavy duty escalara (stair step hand truck)  
is recommended for lifting the appliance body.  
Floor Protection - Model CI1000HT  
(USA ONLY)  
• Existing Chimneys  
The floor protector must meet or exceed the minimum thermal require-  
ments as defined here (see Floor Protection / Hearth Extension Using  
Alternate Material As Floor Protector). If the floor protection is to be  
stone, tile, brick, etc., it must be mortared or grouted to form a continu-  
ousnoncombustiblesurface. Ifachimneyconnectorextendshorizontally  
over the floor, protection must also cover the floor under the connector  
and at least 2” (51 mm) to either side.  
• Wood Storage  
• Aesthetic Considerations  
• Roof Design (rafter locations & roof pitch)  
• Room Traffic  
The floor protector must fully cover the area beneath the appliance and  
extend 18” to the front, 5.2” to the sides, and 0” from the back as shown  
in Figure 1.  
• Proximity to Combustibles  
The installation of these appliances will require some research. Once your  
options are determined, consult with your local building department who  
will be able to give you the necessary installation requirements for your  
area (Is a building permit required? Rooms where installation may not  
be allowed, etc.).

If you plan to vent your stove into an existing masonry chimney, have it  
inspected by a local fire marshal or qualified installer. Remember that a  
stove’s performance is heavily influenced by the chimney and its location  
on the roof. An oversized flue may not provide effective draw, and a flue  
liner may be required (see Draft Requirements on Page 11). Consult your  
dealer or qualified installer before final selection is made.

The appliance should be inspected before use and the chimney cleaned

The hearth pad or alternate material used as a floor/hearth protector must  
be constructed of a durable noncombustible material having an equal or  
better thermal conductivity value (lower k value) of k =.84 BTU/IN FT2  
HR °F or a thermal resistance that equals or exceeds r = 1.19 HR °F FT2

Note: Any noncombustible material having a minimum thickness of 1/2”  
(13 mm) whose k value is less than .84 or whose r value is more than  
1.19 is acceptable. If the alternate material used has a higher k value  
or lower r value will require a greater thickness of the material used. In  
some cases, if the k value is less or the r value higher, a thinner material

Single Wall Pipe With Pipe Shield / Reduced Clearance -  
CI1000HT  
** If the hearth extension material(s) that is intended to be used is  
NOT listed on Table 3, the material can still be used if the material(s)  
is noncombustible. However, the manufacturer of the material must  
provide either the listed k-value per inch or r-value per inch with listed  
thickness so that the minimum thickness required for the hearth can  
be calculated (per instructions on this Page and/or as specified in the  
NFI Certification Manuals).  
Using single wall 24 MSG black or 25 MSG blued steel connector pipe  
with factory-built chimney listed to either UL 103HT or ULC S629. The  
use of a pipe shield for 6” connector with 1” clearance to the pipe is  
mandatory.

Table 5 - Model CI1000HT (see Figures 3 and 4)  
Protected Wall Clearance - CI1000HT and CI2000HT  
Some local codes will allow reduced clearances when the stove is  
installed adjacent to a protected wall system. The variance must be  
approved by your local building official. Normally, the protected wall  
system is defined as a non- combustible material with a minimum of  
1” air space behind. Check your local building codes or with a qualified  
installer (Ref. NFPA 211).

COMBUSTIBLE WALL CLEARANCE – USA & Canada  
WARNING: It is very important that you observe the minimum  
clearances.  
A
E
There are listed clearances for your stove which were determined in a  
Laboratory test using various “classes” of stove pipe or chimney. Mini-  
mums are first established for the stove itself and increased based on  
how much heat is transferred by each class of pipe.  
B
Position the unit no closer than the minimum clearances to combustible  
materials. Check that no overhead cross members in the ceiling or roof  
will be cut. Reposition unit if necessary being careful not to move closer  
than the minimum clearances.
