Rules For Safe Installation And Operation

SAVE THESE INSTRUCTIONS! READ THESE RULES AND THE INSTRUCTIONS CAREFULLY.

1.  Check local codes. The installation must comply with their rulings. Do not install this heater in a mobile home 

or trailer.

2.  Always connect this heater to a chimney or vent to the outside. Never vent to another room or inside a 

building.

3.  Do not connect this heater to an aluminium Type B gas vent. This is not safe and is prohibited by all codes. 

This heater requires connection to approved chimneys: Either a chimney complying with the requirements 

for  Type  HT  chimneys  in  the  Standard  for  Chimneys.  Factory  Built,  Residential  Type  and  Building  Heating 

Appliance, UL 103, or a code approved masonry chimney with a flue liner, preferably round. A larger masonry 

flue may be used, so long as the flue-section diameter is not greater than 50 sq. in.

4.  The chimney portion (whether factor-built or masonry) must be tall enough to provide sufficient draft and 

safe exit of smoke and combustion products.

5.  Be sure that your Chimney is safely constructed and in good repair. Have the chimney inspected by the Fire 

Department or a qualified inspector (such as a Chimney sweep). Your insurance company may be able to 

recommend a qualified inspector.

6.  Inspect  chimney  connector  and  chimney  twice  monthly  during  the  heating  season  for  any  deposit  of 

creosote or soot which must be removed.

7.  Provide air for combustion from outside the house into the room where the heater is located. If the intake is 

not in the same room, air must have free access to the room. 

Clearances To Combustibles

Minimum clearances to unprotected combustible walls and ceilings as noted by figures 2 through 4 must be 

maintained.    Drapes,  curtains,  furniture  and  other  combustible  materials  should  be  kept  much  further  away 

from the heater to avoid fire.  If you choose to, you may install the heater and chimney connector closer to 

combustible surfaces than indicated by Figures 2 through 4 IF a clearance reduction system is also installed to 

protect combustible ceilings and walls near the heater and chimney connector.  However, there are limits to how 

close the heater and chimney connector can be installed to combustible surfaces protected by a clearance 

reduction system.

A correctly installed clearance reduction system protects the combustible surfaces well beyond  the sides and 

above the top of the heater and beyond the sides and top of the chimney connector pipe.

Two common types of clearance reduction systems use sheet metal with a minimum thickness of 28 gauge 

(galvanized steel, aluminium, copper) or a 3-1/2 inch (4 inch nominal) thick masonry wall.  Either of these materials 

must be spaced out 1 inch from the combustible surfaces.  With sheet metal, non-combustible spacers are used 

to maintain the 1 inch air space.  With a masonry wall, metal wall ties and furring strips, if needed are used to 

anchor the brick to the wall.  To avoid excessive heat transmission, the spacers or wall ties should not be placed 

directly behind the heater or chimney connector.  The 1 inch air space provides free air circulation.  It is essential 

that there be openings at the top and bottom of these clearance reducers so cool air can enter at the bottom 

and hot air exit at the top.  It is the “chimney effect” whereby when the air in the space is heated, it rises exiting 

from the top and being replaced by cooler air at the bottom, that makes these shields effective.

Masonry, or other non-combustible products, attached directly to a combustible surface without an air space 

offer very little protection and cannot be considered a clearance reducer unless specified materials have been 

tested and listed for direct attachment to a combustible surface.  The same applies to thin veneer brick and 

stone coverings.  These materials provide adequate protection only when mounted on sheet metal with a 1 inch 

spacing to the wall.

A variety or prefabricated clearance reduction systems which have been tested and listed are available through 

heater  dealers.    Always  look  for  a  safety  listing  label  on  the  product  when  selecting  a  clearance  reduction 

system and make sure it is designed for solid fuel appliances.  The manufactures of these systems provide specific 

installation instructions that must be followed exactly for a safe installation.
