Radiance Direct Vent Gas Heater
Vent Termination Clearances
When planning the installation, consider the location of the vent terminal and clearances. Some of the most common clearances to keep in mind are shown in Figure 11.
Important: All vent clearances must be maintained. Check your vent termination clearances against Figures 11 through 13.
The vent should be placed so that people cannot be burned by accidentally touching the vent surfaces when the stove is operating.
The vent termination should be located where it cannot be damaged by such things as automobile doors, lawn mowers or snowblowers and it should be located away from areas where it could become blocked by snow, etc.
Some considerations are:
•Obstructions or impediments to venting.
•Nearby combustible materials that could come into contact with combustion exhaust gases.
•Other nearby openings {within 12” (305 mm)} through which exhaust gas could reenter the build- ing.
•All vegetation within 3’ (76 mm) that may interfere with the draft.
Other factors that influence where the installation will be sited include the location of outside walls, where additional heat may be desired in the home, where the family members gather most regularly, and perhaps most importantly, the distance limitations of the venting system.
Your stove is approved to be vented either through the side wall, or vertical through the roof.
•CFM Corporation does not require any opening for inspection of vent pipe.
•Only CFM Corporation, Simpson DuraVent and Selkirk Corporation venting components specifi- cally approved and labelled for this stove may be used.
•Minimum clearances between vent pipes and combustible materials is one (1”) inch (25 mm), except where stated otherwise.
•Venting terminals shall not be recessed into a wall or siding.
•Horizontal venting must be installed on a level plane without an inclining or declining slope.
There must not be any obstruction such as bushes, garden sheds, fences, decks or utility buildings within 24” from the front of the termination hood.
Do not locate termination hood where excessive snow or ice build up may occur. Be sure to check vent termi- nation area after snow falls, and clear to prevent ac- cidental blockage of venting system. When using snow blowers, make sure snow is not directed towards vent termination area.
Location of Vent Termination
It is imperative the vent termination be located observ- ing the minimum clearances as shown on this page.
IMPORTANT
•The horizontal termination must not be recessed into the exterior wall or siding.
•Horizontal vent runs must be level toward the vent termination.
•Clearances around the vent termination must be maintained.
•For installations using Simpson DuraVent pipe, parallel installations with minimum wall clearance have restricted access for connecting the Hori- zontal Vent Cap straps to the vent pipe. See the maker’s instructions for recommended installa- tion procedures.
