Maintain these minimum clearances to combustibles from appliance and vent surfaces:
Appliance framing:
Use steel stud framing provided.
Non- Combustible Appliance fi nishing:
Front -
7" (178mm) to sides of appliance opening
-
26 1/2" (673mm) above appliance opening
Combustible Appliance fi nishing:
-
63 1/2" (1613mm) from bottom of appliance to enclosure top
-
3" (76mm) to top of vent pipe*
-
2" (51mm) to sides and bottom of vent pipe*
Non-combustible fi nishing material (ie. cement board, brick, stone, tile) must be used to fi nish the front of
the appliance.
The LV38 is installed into a rectangular opening. It is best to frame your appliance after it is positioned and the
vent system is installed. Use the steel stud frame provided.

!
WARNING
RISK OF FIRE!
IN ORDER TO AVOID THE POSSIBILITY OF EXPOSED INSULATION OR VAPOUR BARRIER COMING
IN CONTACT WITH THE APPLIANCE BODY, IT IS RECOMMENDED THAT THE WALLS OF THE
APPLIANCE ENCLOSURE BE “FINISHED” (IE: DRYWALL / SHEETROCK), AS YOU WOULD FINISH
ANY OTHER OUTSIDE WALL OF A HOME. THIS WILL ENSURE THAT CLEARANCE TO
COMBUSTIBLES IS MAINTAINED WITHIN THE CAVITY.
DO NOT NOTCH THE FRAMING AROUND THE APPLIANCE STAND-OFFS. FAILURE TO MAINTAIN
AIR SPACE CLEARANCE MAY CAUSE OVER HEATING AND FIRE. PREVENT CONTACT WITH
SAGGING OR LOOSE INSULATION OR FRAMING AND OTHER COMBUSTIBLE MATERIALS. BLOCK
OPENING INTO THE CHASE TO PREVENT ENTRY OF BLOWN-IN INSULATION. MAKE SURE
INSULATION AND OTHER MATERIALS ARE SECURED.
WHEN CONSTRUCTING THE ENCLOSURE ALLOW FOR FINISHING MATERIAL THICKNESS TO
MAINTAIN CLEARANCES. FRAMING OR FINISHING MATERIAL CLOSER THAN THE MINIMUMS
LISTED MUST BE CONSTRUCTED ENTIRELY OF NON-COMBUSTIBLE MATERIALS. MATERIALS
CONSISTING ENTIRELY OF STEEL, IRON, BRICK, TILE, CONCRETE, SLATE, GLASS OR PLASTERS,
OR ANY COMBINATION THEREOF ARE SUITABLE. MATERIALS THAT ARE REPORTED AS PASSING
ASTM E 136, STANDARD TEST METHOD FOR BEHAVIOUR OF MATERIALS IN A VERTICAL TUBE
FURNACE AT 1382° F (750°C) AND UL763 SHALL BE CONSIDERED NON-COMBUSTIBLE
MATERIALS.
MINIMUM CLEARANCE TO COMBUSTIBLES MUST BE MAINTAINED OR A SERIOUS FIRE HAZARD
COULD RESULT.
THE APPLIANCE REQUIRES A MINIMUM ENCLOSURE HEIGHT. MEASURE FROM THE APPLIANCE
BASE.
IF STEEL STUD FRAMING KITS WITH CEMENT BOARD ARE PROVIDED, OR SPECIFIED IN THE
INSTALLATION INSTRUCTIONS, THEY MUST BE INSTALLED.
IF SPECIFIED IN THE INSTALLATION INSTRUCTION FINISHING MUST BE DONE USING A NON-
COMBUSTIBLE MATERIAL SUCH AS NON-COMBUSTIBLE BOARD, CERAMIC TILE, MARBLE, ETC.
DO NOT USE WOOD OR DRYWALL. ANY FIRE RATED DRYWALL IS NOT ACCEPTABLE

*HORIZONTAL VENT SECTIONS:
A minimum clearance of 3" (76mm) to the top and 2" (51mm) to the sides
and bottom of the vent pipe on all horizontal runs to combustibles is required when passing through a wall.
Use fi restop spacer W010-2107 (supplied).
Horizontal vent sections within enclosures require a minimum clearance of 6" (152mm) at the top of the vent
pipe, see “MINIMUM CLEARANCE TO COMBUSTIBLE ENCLOSURES” section and 1" (25mm) to the sides of
the vent pipe.
*VERTICAL VENT SECTIONS:
A minimum of 1" (25mm) all around the vent pipe on all vertical runs to
combustibles is required when passing through a ceiling. Use fi restop spacer W500-0028 (not supplied).
