Framing - Napoleon BHD4P Installation And Operating Instructions Manual

5.0 FRAMING

When using optional finishing accessories, the framing dimensions and finishing materials may differ from what
is outlined in the section below; refer to the leaflet instructions supplied in the accessory kit for specific framing
and finishing specifications.
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
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
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
MINIMUM CLEARANCE TO COMBUSTIBLES MUST BE MAINTAINED OR A SERIOUS FIRE HAZARD
THE APPLIANCE REQUIRES A MINIMUM ENCLOSURE HEIGHT. MEASURE FROM THE APPLIANCE
IF STEEL STUD FRAMING KITS WITH CEMENT BOARD ARE PROVIDED, OR SPECIFIED IN THE
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
It is best to frame your appliance after it is positioned and the vent system is installed.
When roughing in the appliance, raise the appliance to accommodate for the thickness of the finished floor
materials, i.e. tile, carpeting and hard wood.
Maintain these minimum clearances to combustibles from appliance and vent surfaces:
Combustible Appliance framing:
- 1/4" (6.4mm) to the sides of appliance
- 8 1/4" (210mm) to the top of appliance
Combustible Appliance finishing:
- 0" (0mm) above the appliance opening
- 50" (127cm) from bottom of appliance to enclosure top
- 62 1/4" (158.2cm) from bottom of appliance to ceiling
- 3" (76mm) to top of vent pipe*
- 2" (51mm) to sides and bottom of vent pipe*
- 0" (0mm) to the sides and top of appliance
*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, see "MINIMUM CLEARANCE
TO COMBUSTIBLE ENCLOSURES" section. Use firestop assembly W010-3210. If reduced to 4/7", use
W010-3440 firestop.
NOTE: The minimum clearances around the horizontal vent pipe to combustible materials may be
reduced from 3" (76.2mm) / 2" (50.8mm) to 1" (25mm) in those installations with a minimum 52" (132cm)
vertical vent rise made immediately off the appliance collar and where the vent has been reduced to
4/7" from 5/8" at the appliance collars.
*VERTICAL VENT SECTIONS: A minimum of 2" (51mm) all around the vent pipe on all vertical runs to
combustibles is required. Use firestop spacer W010-3210.
