Venting requirements

WARNING

  • Risk of fire. Maintain specifi ed air space clearances to vent pipe and appliance.
  • The vent system must be supported every 3’(0.9m) for both vertical and horizontal runs. Use support ring assembly W010-0067 or equivalent non-combustible strapping to maintain the minimum clearance to combustibles for both vertical and horizontal runs. Spacers are attached to the inner pipe at predetermined intervals to maintain an even air gap to the outer pipe. This gap is required for safe operation. A spacer is required at the start, middle, and end of each elbow to ensure this gap is maintained. These spaces must not be removed.

This appliance uses a 5” (127mm) exhaust / 8” (203.2mm) air intake vent pipe system. Refer to the section applicable to your installation.
For safe and proper operation of the appliance follow the venting instructions exactly. Deviation from the minimum vertical vent length can create difficulty in burner start-up and/or carboning. Under extreme vent configurations, allow several minutes (5-15) for the flame to stabilize after ignition. Although not a requirement, it is recommended for vent lengths that pass through unheated spaces (attics, garages, crawl spaces) be insulated with the insulation wrapped in a protective sleeve to minimize condensation. Provide a means for visually checking the vent connection to the appliance after the appliance is installed. Use a firestop, vent pipe shield or attic insulation shield when penetrating interior walls, floor or ceiling.
The vent terminal may be painted with a high temperature paint to match exterior colours. Use an outdoor paint suitable for 400°F (200°C). Application and performance of paint is the consumer’s responsibility. Spot testing is recommended.

Note:
If for any reason the vent air intake system is disassembled; reinstall per the instructions provided for the initial installation.
This appliance must be installed with a continuous connection of exhaust and air intake vent pipes. Utilizing alternate constructions, such as a chimney as part of the vent system, is not permitted.
Use only Wolf Steel, Metal-Fab, BDM, Simpson Dura-Vent, or Selkirk Direct Temp venting components. Minimum and maximum vent lengths, for both horizontal and vertical installations, clearances from vent pipes to combustibles and air terminal locations as set out in this manual apply to all vent systems and must be adhered to. For Metal-Fab, BDM, Simpson Dura-Vent, or Selkirk Direct Temp, follow the installation procedure provided with the venting components or on the website
for your venting supplier.
A starter adaptor must be used with the following vent systems and may be purchased through Wolf Steel or from the corresponding supplier listed below:

Venting System| Manufacturer| Starter Adapter Part Number| Supplier| Website
---|---|---|---|---
SureSeal| Metal-Fab| 5DNA| Wolf Steel| www.mtlfab.com
Direct Vent Pro| Simpson DuraVent| W175-0170| Wolf Steel| www.duravent.com
Pro-Form| BDM| N/A| BDM| www.dalsinmfg.com
Direct Temp| Selkirk| 5DT-AAN| Selkirk| www.selkirkcorp.com
Ventis| Olympia Chimney _ and Venting| VDV-NA05-58F| Olympia Chimney  and Venting| www.olympiachimney.com

Connections made by means of an adaptor at the appliance, as well as the connection at the vent terminal must be sealed.
RTV sealant may be used on both the inner exhaust and outer intake vent pipe joints of all other approved vent systems, except for the exhaust vent pipe connection to the appliance flue collar which must be sealed using the black high temperature sealant Mill Pac.
For all vent systems is strongly recommend for all installations but required when power venting the appliance, that the outer air intake joints are sealed using either high  temperature silicone (RTV) or a suitable aluminum tape that covers each joint in the vent system entirely around its circumference. This will ensure the best performance in every application and avoids performance or condensation concerns that may occur in “tightly” constructed homes, particularly those in cold climates.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following termination kits: wall terminal kit GD422-1,
GD422R-2, ST58U-1 or 1/12 to 7/12 pitch roof terminal kit GD410, 8/12 to 12/12 roof terminal kit GD411, flat roof terminal kit GD412 or periscope kit GD401 (for wall penetration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot (1.5m) vent kit GD420 or the 10 foot (3.1m) vent kit GD430.
All vent measurements start at the base of the air collar of the appliance.
For optimum flame appearance and appliance performance, keep the vent length and number of elbows to a minimum.
The air terminal must remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed and undamaged.
Rigid and flexible venting systems must not be combined. Different venting manufacturer components must not be combined.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal run is 20 feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). The maximum number of vent connections is two horizontally or three vertically (excluding the appliance and the air terminal connections) when using flexible venting.
An insulated sleeve has been supplied and must be installed on all rear vent applications for the first 24” (61cm).
Horizontal runs may have a 0” (0mm) rise per foot/meter however for optimum performance it is recommended that all horizontal runs have a minimum 1/4” (21mm) rise per foot/meter using fl exible venting. For safe and proper operation of the appliance, follow the venting instructions exactly.
A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings. Local codes or regulations may require different clearances.
Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼” (31.8mm) air gap all around between the inner liner and outer liner is required for safe operation.
This appliance is certified for use with a power vent kit (top vent only). Contact your local authorized dealer for more information.

Rough framing

note:
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 specifi cations.

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 “fi nished” (i.e. 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 E136, standard test method for behaviour of materials in a vertical tube furnace at 1382ºF (750ºC) and UL763 shall be considered non-combustible materials.
  • Minimum clearance to combusibles 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 board, ceramic tile, marble, etc. Do NOT use wood or drywall. Any fire rated drywall is not acceptable.

Venting installation

WARNING

  • Ensure to unpack all loose materials from inside the firebox prior to connecting the gas and electrical supply
  • If your appliance is supplied with a remote, ensure the remote receiver is in the “OFF” position prior to connecting the gas and electrical supply to the appliance.
  • For safe and proper operation of the appliance, follow the venting instructions exactly.
  • The appliance exhaust flue collar must be sealed using Mill Pac. All exhaust and intake vent pipe joints must be sealed using red RTV high temp silicone sealant (W573-0002) (not supplied) or black high temp Mill Pac (W573-0007) (not supplied).
  • If using pipe clamps to connect rigid vent components, a minimum of 3 screws must also be used to ensure the connection cannot slip off.
  • Do not clamp the fl exible vent pipe.
  • Risk of fire, explosion, or asphyxiation. Improper support of the entire venting system may allow vent to sag and separate. Use vent run supports and connect vent sections per installation instructions.
  • Risk of fire, do not allow loose materials or insulation to touch the vent pipe. Remove insulation to allow for the installation of the attic shield and to maintain clearances to combustibles.
  • Do not fill the space between the vent pipe and enclosure with any type of material. Do not pack insulation or combustibles between ceiling firestops. Always maintain specifi ed clearances around venting and fi restop systems. Install wall shields and fi restops as specifi ed. Failure to keep insulation or other materials away from vent pipe may cause fire.
  • For gas stoves only: If the appliance is installed directly on carpeting, vinyl tile, or other combustible material other than wood flooring, the appliance shall be installed on a metal or wood panel extending the full width and depth, unless otherwise tested.

4.1 horizontal installation
WARNING

  • The firestop assembly must be installed with the vent shield to the top.
  • Terminals must not be recessed into a wall or siding more than the depth of the return flange of the mounting plate.
  • The vent shield must be fixed in place by fastening the extended vent shield to the bend tabs using the supplied fasteners.

This application occurs when venting through an exterior wall. Having determined the correct height for the air terminal location, cut and frame a hole in the exterior wall, as illustrated, to accommodate the firestop assembly. Dry fit the firestop assembly before proceeding to ensure the brackets on the rear surface fit to the inside surface of the horizontal framing.
The vent shield must be installed to the full depth of the combustible wall. The length of the vent shield may cut shorter for combustible walls that less than 8 1/2” (216mm) thick.

NAPOLEON BX42NTRE Vent Natural Gas Fireplace - Fig 30

note:
Bend the tabs for reduced side clearances or move the shield for reduced top clearances (dependent on specifi c appliance clearances). Do not fill the air space between the firestop spacer and the exterior wall with any type of insulating material (i.e. spray foam).

A. Fold the vent shield up so that it is perpendicular to the spacer plate.
B. Bend the tabs located on either side of the vent shield so that they are just shy of 90º to the spacer plate.
C. On both sides of the firestop, fasten the (W570-0018) screws through the clearance holes in the bend tabs and threaded into the holes in the vent shield.
D. Apply a bead of caulking around the outer edge of the fi restop assembly.
E. Screw the firestop onto the wall/framing, using 4 screws.
F. Once the vent pipe is installed in its final position, apply red RTV silicone (W573-0002) (not supplied) between the pipe and the firestop.

note:
Where the venting passes horizontally through a wall, you MUST use a Wolf Steel firestop for all rigid and flexvent systems. The gap between the outside diameter of the vent and the firestop MUST be completely sealed with high temperature RTV. When using flexventing, use fi restop assembly W010-4479 (not supplied). When using rigid venting, use firestop assembly 5DHFSN (not supplied).

4.2 vertical installation
This application occurs when venting through a roof. Installation kits for various roof pitches are available from your authorized dealer / distributor. See the “accessories” section to order specifi c kits required.
A. Determine the air terminal location, cut and frame a square opening, as illustrated, in the ceiling and the roof to provide the minimum 1″ (25mm) clearance between the vent pipe and any combustible material. Try to center the vent pipe location midway between two joists to prevent having to cut them. Use a plumb bob to line up the center  of the openings. A vent pipe shield will prevent any materials such as insulation, from filling up the 1″ (25mm) air space around the pipe. Nail headers between the joist for extra support.
B. Apply a bead of caulking (not supplied) to the framework or to the Wolf Steel vent pipe shield plate or equivalent (in the case of a finished ceiling), and secure over the opening in the ceiling. A firestop must be placed on the bottom of each framed opening in a roof or ceiling that the venting system passes through. Apply a bead of caulking all around and place a firestop spacer over the vent shield to restrict cold air from being drawn into the room or around the fireplace. Ensure that both spacer and shield maintain the required clearance to combustibles. Once the vent pipe is installed in its final position, apply red RTV silicone (W573-0002) (not supplied) between the pipe and the firestop assembly.
C. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any materials, such as insulation, from fi lling up the 1″ (25mm) air space around the pipe.
NAPOLEON BX42NTRE Vent Natural Gas Fireplace - Fig 32

note:
Where the venting passes vertically through a ceiling you use MUST use a Wolf Steel firestop for all rigid and fl ex vent systems. The gap between the outside diameter of the vent and the firestop MUST be completely sealed with high temperature RTV.
For 4”/7” appliances:
When using flex venting, use firestop assembly W500-0292 (not supplied).
When using rigid venting, use firestop assembly 4DFS (not supplied).

8.1 pilot-on-demand
This appliance is equipped with an “On Demand” intermittent pilot ignition system (IPI) which also includes a continuous pilot ignition (CPI) mode with an integrated seven day timer. This system minimizes your appliance’s carbon footprint as well as reducing its annual fuel consumption and operating costs.
In IPI mode, the pilot will ignite prior to the main burner, when the appliance is turned on using a switch, remote or from a call for heat with the thermostat (if equipped). Once the appliance is turned off (or the call for heat is satisfi ed), the main burner and pilot flame will shut down.
The continuous (CPI) mode is intended to enhance the performance of the appliance during the startup phase in colder climates and extreme weather by keeping the system warm when the main burner is not in use. However, the timer feature provides the convenience that the appliance automatically switches off the pilot when the appliance has not been used for seven days to save unnecessary fuel consumption.
When the CPI function is turned on, the pilot will remain on after the main burner is turned off. A timer will then begin the countdown for approximately seven days before shutting off the pilot if the appliance is not used. This countdown will reset anytime the appliance main burner is used. Therefore, if the appliance is regularly used day to day, the pilot will remain on. However, this system does not require the user to remember to turn the pilot off as summer approaches and avoids unnecessary fuel consumption while still readily turned back on when the cold weather returns.

**Your appliance may be equipped with an ACS or remote control device (Fig.

  1. which enables you to select IPI or CPI modes.**

If your appliance is equipped with an ACS switch, it has the option to change modes:
Fig. 2: Flipping the switch ON turns on the continuous pilot with timer and flipping the switch OFF turns on the intermittent pilot ignition.
Fig. 3: If installed with the blue wire facing up, flipping the switch UP turns on the continuous pilot with timer and flipping the switch DOWN turns on the intermittent pilot ignition. If installed with the white wire facing up, the opposite is true.
If your appliance is equipped with a remote control device capable of selecting IPI / CPI modes, refer to remote operating instructions.
In order to start your pilot, turning the main burner on with the switch, remote or thermostat and then turning it off will reactivate the continuous pilot mode and reset the seven day timer.

10.6 clearances around appliance (TV and valuable objects)

NAPOLEON BX42NTRE Vent Natural Gas Fireplace - Fig 60

NAPOLEON BX42NTRE Vent Natural Gas Fireplace - Fig 61

  • TV applications were tested with the minimum enclosure dimensions and the maximum recess permissible.
    This data is provided in good faith and is not a guarantee for every application and television. Care and consideration should be taken when planning these installations to ensure the temperatures around the TV meet all manufacturer’s recommended operating temperatures. Increasing the height of the mantel and/or TV above the fireplace opening, the protrusion of mantel and the volume of the enclosure all have the effect of reducing the temperature above the fi replace. It is always recommended to use the optional heat management kit when considering mounting a television above the fireplace.

note:

  • Electronic appliance temperatures must be validated at the time of installation as air flow characteristics within the room can vary and maximum acceptable operating  temperatures can vary from appliance to appliance. Electronic appliances cannot be used where the electronic appliance temperature exceeds the manufacturer’s maximum allowable operating temperatures (see electronic appliance manufacturer’s specifi cations). Operating a television above the manufacturer’s maximum allowable operating temperature will result in premature failure.
  • Mantel height and depth must conform to mantel clearance requirements specifi ed in this manual, see “minimum clearance to combustible mantel” section in installation manual.
  • Electronic appliance temperatures may be further reduced by increasing the horizontal distance between the front of the electronic appliance and the front edge of the mantel or by increasing dimension “A” or “B”. However, increasing the gap between the top of the mantel and the bottom of the electronic appliance beyond the maximum recommended figure, typically results in higher temperatures. Minimum clearance between the mantel and bottom of the electronic appliance should be maintained to allow  air circulation below and behind the electronic appliance.

10.7 air flow cover installation

NAPOLEON BX42NTRE Vent Natural Gas Fireplace - Fig 62

Install one air flow cover at each end of the burner stiffener rail (2 total) using 4 screws (supplied).
