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 oriﬁ ce 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 oriﬁ ce 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 qualiﬁ ed 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, Stan-

dard 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.

4 Heatilator • Novus BV-Mesh • 4031-553 Rev F • 11/07

F. Combustible Materials

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

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 ofﬁ cials 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 conﬁ guration 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 BV-Mesh • 4031-553 Rev F • 11/07 5

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 ﬁ replaces successfully. Considerations for successful draft include:

• Preventing negative pressure.

• Location of ﬁ replace and chimney.

Negative Pressure

Negative pressure results from the imbalance of air available for the ﬁ replace 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 ﬁ replace.

• Avoid installing the ﬁ replace 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 ﬁ replaces in basements.

Location of the ﬁ replace 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 ﬁ re.

• 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 ﬁ replace location relative to ﬂ oor 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 ﬂ oor of the chase should be insulated. Vapor and air inﬁ ltration 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 speciﬁ cations in manual.

• Locate and install appliance to all clearance speciﬁ cations in manual.

I. Air Shutter Setting

This appliance has an adjustable air shutter (which controls the primary air) factory set for the minimum vertical vent run (see Figure 12.10). If your installation has more than the minimum required vertical vent length, adjustment of the air shutter may be necessary to obtain optimal ﬂ ame appear- ance. This should be adjusted by a qualiﬁ ed installer at

the time of installation.

• If the vent configuration is installed incorrectly, the vent may cause the ﬂ ames inside the appliance to lift or “ghost,” which is a dangerous situation. Inspect the ﬂ ames after installation to ensure proper performance. If the vent conﬁ guration is correct, yet the ﬂ ames are lifting or ghosting, shut off the gas to the appliance and contact the dealer.

• Your air shutter is provided at 1/8 in. open for natural gas, 3/8 in. open for propane (30 in./33 in. appliances), and full open for 36 in. and 42 in. propane appliances. In the event soot is accumulating in your appliance, the air shutter should be opened farther. This can be done by opening the control access panel and locating the two wing studs and two wing nuts attaching the valve assembly to the ﬁ rebox. Remove the wing nuts and wing studs, slide the valve assembly to the left and lower. Rotate the valve assembly horizontally and remove from underneath the appliance. See Figure 12.11.

Figure 12.10 Air Shutter

Note: To avoid damage to the pilot assembly,

Initial Break-in Procedure

When you light the appliance, you may notice that it produces heat which does have an associated odor or smell. If you feel this odor is excessive it may require the initial three to four hour continuous burn on high followed by a second burn up to 12 hours to fully drive off any odor from paint and lubricants used in the manufacturing process. Condensation of the glass is normal

CAUTION

• Prevent accidental appliance operation when not attended.

• Unplug or remove batteries from remote control if absent or if appliance will not be used for an extended period of time.

• Property damage possible from elevated temperatures.

Note: This appliance should be run three to four hours on the initial start-up. Turn it off and let it cool completely. Remove and clean the glass. Replace the glass and run the appliance for an additional 12 hours. This will help cure the products used in the paint and logs.

During this break-in period it is recommended that some windows in the house be opened for air circulation. This will help avoid setting off smoke detectors, and help eliminate any odors associated with the appliance’s initial burning.

Troubleshooting

With proper installation, operation and maintenance your gas appliance will provide years of trouble-free service. If you do experience a problem, this troubleshooting guide will assist a qualiﬁ ed service person in the diagnosis of a problem and the corrective action to be taken. This troubleshooting guide can only be used by a qualiﬁ ed service technician.

Using a match, light the pilot. If the pilot lights, turn off the pilot and trigger the red or black piezo ignitor button again. If the pilot lights, an improper gas/air mixture caused the bad lighting and a longer purge period is recommended. If the pilot will not light, ensure the gap at the electrode and pilot is 1/8 in. to have a strong spark. If the gap is OK, replace the pilot.

Check the remote shut-off valves from the appliance. There is usually a valve near the gas main. There can be more than one valve between the appliance and the main.

adjust the pilot for maximum ﬂ ame impingement.

Ensure that the thermocouple connection at the gas valve is fully inserted and tight (hand tighten plus 1/4 turn).

Disconnect the thermocouple from the valve, place one millivolt meter lead wire on the tip of the thermocouple and the other meter lead wire on the thermocouple copper lead. Start the pilot and hold the valve knob in. If the millivolt reading is less than 15mV, replace the thermocouple.

Check the ON/OFF switch and wires for proper connections. Place the jumper wires across the terminals at the switch. If the burner comes on, replace the defective switch. If the switch is OK, place the jumper wires across the switch wires at the gas valve. If the burner comes on, the wires are faulty or connections are bad.

If the pilot ﬂ ame is not close enough physically to the thermopile, adjust the pilot ﬂ ame.

Be sure the wire connections from the thermopile at the gas valve terminals are tight and that the thermopile is fully inserted into the pilot bracket.

Check the thermopile with a millivolt meter. Take the reading at TH-TP&TP terminals of the gas valve. The meter should read 325 millivolts minimum while holding the valve knob depressed in the pilot position, with the pilot lit, and the ON/OFF switch in the OFF position. Replace the faulty thermopile of the reading is below the speciﬁ ed minimum.

With the pilot in the ON position, disconnect the thermopile leads from the valve. Take a reading at the thermopile leads. The reading should be 325 millivolts minimum. Replace the thermopile if the reading is below the minimum.

position. Check the millivolt meter at the thermopile terminals. The millivolt meter should read greater than 125mV. If the reading is acceptable, and if the burner does not come on, replace the gas valve.

D. Limited Lifetime Warranty

Gas Appliance (Fireplace) Limited Lifetime Warranty

HEARTH & HOME TECHNOLOGIES INC. (“HHT”) extends the following warranty for HEATILATOR® gas

appliances installed in the United States of America or Canada (the "Appliance"). Dealers and employees of HHT have no authority to make any warranty or authorize any remedies in addition to or inconsistent with the terms of this warranty.

Limited Lifetime Warranty

HHT warrants the Appliance for component failure due to a manufacturing defect of any of the following components: combustion chamber, burner pan, and logs. The Limited Lifetime Warranty speciﬁ ed above is subject to the conditions, exclusions and limitations listed below, is for the period the Appliance is owned by the original homeowner only, and is nontransferable.

1 Year Limited Warranty

HHT warrants the Appliance to be free from failure of any of the following components for a period of one year after installation: valve, ﬂ exible gas line connector, glass panel, fan, direct vent chimney components, factory paint, gasket, piezo ignitor, thermopile, thermocouple, junction box, pilot assembly, shutoff valve, high limit switch, refractory liners, transformer, and control box. If the Heatilator Appliance is found to be defective in either material or workmanship within one year of the date of original installation, HHT will provide replacement parts at no charge and pay reasonable labor and freight costs, and is for the period of one year following the date of original installation of the Appliance.

Conditions, Exclusions, & Limitations of Liability

A. Both the Limited Lifetime and 1 Year Limited Warranties supplied by HHT apply only while the Appliance is in its location of original

installation. HHT’s obligation under this warranty does not extend to damages resulting from (1) installation, operation or maintenance of the Appliance not in accordance with the Installation Instructions, Operating Instructions, and the Listing Agent Identiﬁ cation Label furnished with the Appliance; (2) installation which does not comply with local building codes; (3) shipping, improper handling, improper operation, abuse, misuse, accident or unworkmanlike repairs; (4) environmental conditions, inadequate ventilation or drafting caused by tight sealing construction of the structure, air handling devices such as exhaust fans or forced air furnaces, or other causes; (5) use of fuels other than those speciﬁ ed in the Operating Instructions; (6) installation or use of components not supplied with the Appliance or any other components not expressly authorized and approved by HHT; and/or (7) modiﬁ cation of the Appliance not expressly authorized and approved by HHT in writing. This warranty is limited to only the component parts manufactured or supplied by HHT.

B. HHT’s liability under both the Limited Lifetime Warranty and the 1 Year Limited Warranty is limited to the replacement and repair of

defective components or workmanship during the applicable period. HHT may fully discharge all of its obligations under such warranties by repairing the defective component(s) or at HHT’s discretion, providing replacement parts at no charge and paying reasonable labor and freight costs.

C. EXCEPT TO THE EXTENT PROVIDED BY LAW, HHT MAKES NO EXPRESS WARRANTIES OTHER THAN THE WARRANTY

SPECIFIED HEREIN. THE DURATION OF ANY IMPLIED WARRANTY IS LIMITED TO DURATION OF THE WARRANTY SPECIFIED ABOVE.

D. Some states do not allow exclusions or limitations of incidental or consequential damages, so those limitations may not apply to you.

This warranty gives you speciﬁ c rights; you may also have other rights which vary from state to state.
