D. High Altitude Installations

U.L. Listed gas appliances are tested and approved without requiring changes for elevations from 0 to 2000 feet in the U.S.A. and Canada.

When installing this appliance at an elevation above 2000 ft, it may be necessary to decrease the input rating by changing the existing burner orifice to a smaller size. Input rate should be reduced by 4% for each 1000 ft above a 2000 ft elevation in the U.S.A., or 10% for elevations between 2000 and 4500 ft in Canada. If the heating value of the gas has been reduced, these rules do not apply. To identify the proper orifice size, check with the local gas utility.

If installing this appliance at an elevation above 4500 ft (in Canada), check with local authorities.

WARNING

Do NOT use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

E. Non-Combustible Materials

Material which will not ignite and burn. Such materials are those consisting entirely of steel, iron, brick, tile, concrete, slate, glass or plasters, or any combination thereof.

Materials that are reported as passing ASTM E 136, Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750° C, shall be considered non-combus- tible materials.

Note: This installation must conform with local codes. In the absence of local codes you must comply with the National Fuel Gas Code, ANSI Z223.1-latest edition in the U.S.A. and the CAN/CGA B149 Installation Codes in Canada.

F. Combustible Materials

Materials made of or surfaced with wood, compressed paper, plant fibers, plastics, or other material that can ignite and burn, whether flame proofed or not, or whether plastered or unplastered shall be considered combustible materials.

Heatilator • Novus NBV • 4055-188 Rev C • 04/08

2 Getting Started

A. Design and Installation Considerations

Heatilator B-vent gas appliances are designed to operate with all exhaust gases expelled to the outside of the building, and combustion air pulled from the room.

CAUTION

Check building codes prior to installation.

Installation MUST comply with local, regional, state and national codes and regulations.

Consult insurance carrier, local building, fire officials or authorities having jurisdiction about restrictions, installation inspection, and permits.

When planning an appliance installation, it’s necessary to determine the following information before installing:

Where the appliance is to be installed. See Sections 3 and 4.

The vent system configuration to be used. See Sections

5 and 6.

Gas supply piping. See Sections 7 and 9.

Electrical wiring. See Sections 7 and 10

Framing and finishing details. See Sections 3, 6 and 11.

Whether optional accessories—devices such as a fan, wall switch, or remote control—are desired. See Section 16.

WARNING

Keep appliance dry.

Mold or rust may cause odors.

Water may damage controls.

Heatilator • Novus NBV • 4055-188 Rev C • 04/08

B. Negative Pressure

WARNING

Asphyxiation Risk

Negative pressure can cause spillage of combustion fumes and soot.

Fire needs to draft properly for safe operation.

Draft is the pressure difference needed to vent fireplaces successfully. Considerations for successful draft include:

Preventing negative pressure.

Location of fireplace and chimney.

Negative Pressure

Negative pressure results from the imbalance of air available for the fireplace to operate properly. Causes for this imbalance include:

Exhaust fans (kitchen, bath, etc.).

Range hoods.

Combustion air requirements for furnaces, water heaters and other combustion appliances.

Clothes dryers.

Location of return-air vents to furnace or air conditioning.

Imbalances of the HVAC air handling system.

Upper level air leaks (recessed lighting, attic hatch opening, duct leaks).

To minimize the effects of negative air pressure, the following must be considered:

Install the outside air kit. Install the intake on the side of the house towards prevailing winds during the heating season.

Ensure adequate outdoor air is supplied for combustion appliances and exhaust equipment.

Ensure furnace and air conditioning return vents are not located in the immediate vicinity of the fireplace.

Avoid installing the fireplace near doors, walkways or small isolated spaces.

Recessed lighting should be a “sealed can” design; attic hatches weather stripped or sealed; attic mounted duct work and air handler joints and seams taped or sealed.

Basement installations should be avoided due to stack effect. Stack effect creates negative pressure in lower levels. Hearth & Home Technologies recommends the use of direct vent fireplaces in basements.

Location of the fireplace and chimney will affect performance. As shown in Figure 2.1 the chimney should:

Be installed through the warm airspace enclosed by the building envelope. This helps to produce more draft, especially during lighting and die-down of the fire.

Penetrate the highest part of the roof. This minimizes the effects of wind turbulence.

Be located away from trees, adjacent structures, uneven roof lines and other obstructions.

Offsets can restrict draft so their use should be minimized. Consider the fireplace location relative to floor and ceiling and attic joists.

B. Construct the Appliance Chase

A chase is a vertical boxlike structure built to enclose the gas appliance and/or its vent system. Vertical vents that run on the outside of a building may be, but are not required to be, installed inside a chase.

Construction of the chase may vary with the type of building. These instructions are not substitutes for the requirements of local building codes. Local building codes MUST be checked.

Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building envelope in any manner.

Walls, ceiling, base plate and cantilever floor of the chase should be insulated. Vapor and air infiltration barriers should be installed in the chase as per regional codes for the rest of the home. Additionally, Hearth & Home Technologies recommends that the inside surfaces be sheet rocked and taped (or the use of an equivalent method) for maximum air tightness.

To further prevent drafts gas line holes and other openings should be caulked with high temp caulk or stuffed with unfaced insulation. If the appliance is being installed on a cement slab, we recommend that a layer of plywood be placed underneath to prevent conducting cold up into the room.

WARNING

Fire Risk

Construct chase to all clearance specifications in manual.

Locate and install appliance to all clearance specifications in manual.

6 Vent Clearances and Framing

A. Pipe Clearances to Combustibles

WARNING

Fire Risk Explosion Risk

Maintain vent clearance to combustibles as specified.

Do not pack air space with insulation or other materials.

National building codes recommend using attic shield to keep loose materials/ insulation from contacting vent.

Failure to keep insulation or other materials away from vent pipe may cause fire.

Follow vent pipe manufacturer’s instructions for all clearances around pipe.

B. Wall Penetration Framing

Do not pack with insulation or other materials.

Use manufacturer's installation instructions for framing dimensions

Figure 6.1 Exterior Wall Hole

For a wall penetration consult B-vent pipe manufacturer’s instructions. Use same dimensional framing materials as those used in the wall construction.

Note: MUST terminate vertically.

C. Vertical Penetration Framing

Use B-vent manufacturer’s firestops to provide adequate clearances.

WARNING

Fire Risk

Keep loose materials or blown insulation from touching the vent pipe.

National building codes recommend using attic shield to keep loose materials/ insulation from contacting vent.

Hearth & Home Technologies requires the use of an attic shield.

WARNING

Fire Risk Asphyxiation Risk

Maintain vent clearance to combustibles as specified.

Do not pack air space with insulation or other materials.

National building codes recommend using attic shield to keep loose materials/ insulation from contacting vent.

Failure to keep insulation or other materials away from vent pipe may cause fire.

This appliance will operate correctly only if adequate ventiation is provided to allow proper draft to the system.

An outside air kit is available as an optional feature with this appliance. An outside air kit helps to decrease the amount of room air taken by utilizing outside air for combustion. We strongly recommend that it be installed.

Note: the outside air kit inlet thimble should be positioned in a manner that will not allow snow, leaves, etc. to block the inlet. A 3 ft. (.91 m) minimum height difference must be maintained from the top of the uppemost chimney section to the outside combustion air inlet. Reference Section 2.

The outside air kit can only be installed on the left side of the appliance.

Refer to the installation instructions provided with the kit.

WARNING

Fire Risk

Asphyxiation Risk

Do not draw outside combustion air from:

Wall, floor or ceiling cavity.

Enclosed space such as an attic or garage.

Close proximity to exhaust vents or chimneys.

Fumes or odor may result.

C. Securing and Leveling Appliance

WARNING

Fire Risk!

Prevent contact with sagging, loose insulation.

Do NOT install against combustible materials such as exposed insulation, plastic and insulation backer.

The diagram shows how to properly position, level, and secure the appliance (see Figure 7.3). Nailing tabs are provided to secure the appliance to the framing members.

Place the appliance into position.

Level the appliance from side to side and front to back.

Shim the appliance as necessary. It is acceptable to use wood shims.

Bend out nailing tabs on each side.

Keep nailing tabs flush with the framing.

Secure the appliance to the framing by using nails or screws through the nailing tabs.

CAUTION

Do NOT notch into the framing around the appliance spacers.
