1Approvals and Codes

Appliance Certification

The Heat & Glo fireplace model discussed in this Installers Guide has been tested to certification standards and listed by the applicable laboratories.

Certification

MODEL: GEM42

LABORATORY: Underwriters Laboratories

TYPE: Direct Vent Gas Fireplace Heater

STANDARD: ANSIZ21.88-2000•CSA2.33-M98•UL307B

Installation Codes

The fireplace installation must conform to local codes. Before installing the fireplace, consult the local building code agency to ensure that you are in compliance with all applicable codes, including permits and inspections.

In the absence of local codes, the fireplace installation must conform to the National Fuel Gas Code ANSI Z223.1 (in the United States) or the CAN/CGA-B149Installation Codes (in Canada). The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes with the National Electric Code ANSI/NFPA No. 70 (in the United States), or to the CSAC22.1 Canadian Electric Code (in Canada).

These models may be installed in a bedroom or bed-sittingroom in the U.S.A. and Canada.

High Altitude Installations

U.L. Listed gas appliances are tested and approved without requiring changes for elevations from 0 to 2,000 feet in the U. S. A. and in Canada.

When installing this appliance at an elevation above 2,000 feet, 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 feet above a 2000 foot elevation in the U.S.A. or 10% for elevations between 2000 and 4500 feet 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 4,500 feet (in Canada), check with local authorities.

2Getting Started

Introducing the Heat & Glo Gas Fireplaces

Heat & Glo direct vent gas fireplaces are designed to operate with all combustion air siphoned from outside of the building and all exhaust gases expelled to the outside.

The information contained in this Installers Guide, unless noted otherwise, applies to all models and gas control systems. Gas fireplace diagrams, including the dimensions, are shown in this section.

Pre-installPreparation

This gas fireplace and its components are tested and safe when installed in accordance with this Installers Guide. Report to your dealer any parts damaged in shipment, particularly the condition of the glass.Do not install any unit with damaged, incomplete, or substitute parts.

The vent system components and trim doors are shipped in separate packages. The gas logs may be packaged separately and must be field installed.

Read all of the instructions before starting the installation. Follow these instructions carefully during the installation to ensure maximum safety and benefit. Failure to follow these instructions will void the owner’s warranty and may present a fire hazard.

The Heat & Glo Warranty will be voided by, and Heat & Glo disclaims any responsibility for, the following actions:

Installation of any damaged fireplace or vent system component.

Modification of the fireplace or direct vent system.

Installation other than as instructed by Heat & Glo.

Improper positioning of the gas logs or the glass door.

Installation and/or use of any component part not manufactured and approved by Heat & Glo, not withstanding any independent testing laboratory or other party approval of such component part or accessory.

ANY SUCH ACTION MAY POSSIBLY CAUSE A FIRE HAZARD.

When planning a fireplace installation, it’s necessary to determine:

Where the unit is to be installed.

The vent system configuration to be used.

Gas supply piping.

Electrical wiring.

Framing and finishing details.

Whether optional accessories—devicessuch as a fan, wall switch, or remotecontrol—aredesired.

If the fireplace is to be installed on carpeting or tile, or on any combustible material other than wood flooring, the fireplace should be installed on a metal or wood panel that extends the full width and depth of the fireplace.

3Installing the Fireplace

Constructing the Fireplace Chase

A chase is a vertical box-likestructure built to enclose the gas fireplace 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.

CAUTION: TREATMENT OF FIRESTOP SPACERS AND CONSTRUCTION OF THE CHASE MAY VARY WITH THE TYPE OF BUILDING. THESE INSTRUCTIONS ARE NOT SUBSTITUTES FOR THE REQUIREMENTS OF LOCAL BUILDING CODES. THEREFORE, YOUR LOCAL BUILDING CODESMUST BE CHECKED TO DETERMINE THE REQUIREMENTS FOR THESE STEPS.

Factory-builtfireplace 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.

This means that the 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, Heat & Glo recommends that the inside surfaces be sheetrocked and taped for maximum air tightness.

To further prevent drafts, the firestops should be caulked to seal gaps. Gas line holes and other openings should be caulked or stuffed with insulation. If the unit 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. Be sure to include spark arrestors for woodburning units if they are required.

THE CHASE SHOULD BE CONSTRUCTED SO THATALL CLEARANCES TO THE FIREPLACE ARE MAINTAINED AS SPECIFIED WITHIN THIS INSTALLERS GUIDE.

Step 1. Locating the Fireplace

The following diagram shows space and clearance requirements for locating a fireplace within a room.

Clearance Requirements

The top, back, and sides of the fireplace are defined by stand-offs.The minimum clearance to a perpendicular wall extending past the face of the fireplace is 12” (304.8 mm). The back of the fireplace may be recessed 17 1/2” (437.5 mm) into combustible construction.

Step 3. Installing the Vent System

A. Vent System Approvals

These models are approved to use DVP-seriesdirect vent pipe components and terminations (see Figures 4 and 5). Approved vent system components are labeled for identification. This pipe is tested and listed as an approved component of the fireplace. The pipe is tested to be run inside an enclosed wall. There is no requirement for inspection openings at each joint within the wall. There is no required pitch for horizontal vent runs.NO OTHER VENTING SYSTEMS OR COMPONENTS MAY BE USED.

Detailed installation instructions are included with each vent termination kit and should be used in conjunction with this

Installers Guide.

The flame and ember appearance may vary based on the type of fuel burned and the venting configuration used.

Identifying Vent Components

The vent systems installed on this gas fireplace may include one, two, or three 90° elbow assemblies. The relationships of vertical rise to horizontal run in vent configurations using 90° elbows MUST BE strictly adhered to. The rise to run relationships are shown in the venting drawings and tables. Refer to the diagrams on the next several pages.

NOTE: Two 45° elbows may be used in place of one 90° elbow. Rise to run ratios in the vent system must be followed if 45° elbows are used.

Figure 22. Minimum Height from Roof to Lowest Discharge Opening

For Vertical Terminations - To locate the vent and install the vent sections:

Locate and mark the vent centerpoint on the underside of the roof, and drive a nail through the centerpoint.

Make the outline of the roof hole around the centerpoint nail.

The size of the roof hole framing dimensions depend on the pitch of the roof. There MUST BE a1-inch(25.4mm) clearance from the vertical vent pipe to combustible materials.

Mark the roof hole accordingly.

Cover the opening of the installed vent pipes.

Cut and frame the roof hole.

Use framing lumber the same size as the roof rafters and install the frame securely. Flashing anchored to the frame must withstand heavy winds.

Continue to install concentric vent sections up through the roof hole (for inside vent installations) or up past the roof line until you reach the appropriate distance above the roof (for outside terminations).

!WARNING: MAJOR U.S. BUILDING CODES SPECIFY MINIMUM CHIMNEY AND/OR

VENT HEIGHT ABOVE THE ROOF TOP. THESE MINIMUM HEIGHTS ARE NECESSARY IN THE INTEREST OF SAFETY. SEE THE PREVIOUS DIAGRAM FOR MINIMUM HEIGHTS, PROVIDED THE TERMINATION CAP IS AT LEAST 20 INCHES FROM AVERTICAL WALL AND 2-FEETBELOW A HORIZONTAL OVERHANG.

NOTE: This also pertains to vertical vent systems installed on the outside of the building.

To seal the roof hole, and to divert rain and snow from the vent system:

Attach a flashing to the roof using nails, and use a nonhardening mastic around the edges of the flashing base where it meets the roof.

Attach a storm collar over the flashing joint to form a water-tightseal. Placenon-hardeningmastic around the joint, between the storm collar and the vertical pipe.

Slide the termination cap over the end of the vent pipe and snap into place.

Step 4. Positioning, Leveling and Securing the Fireplace

Step 7. The Gas Supply Line

NOTE: Have the gas supply line installed in accordance with local building codes by a qualified installer approved and/or licensed as required by the locality. (In the Commonwealth of Massachusetts installation must be performed by a licensed plumber or gas fitter).

NOTE: Before the first firing of the fireplace, the gas supply line should be purged of any trapped air.

NOTE: Consult local building codes to properly size the gas supply line leading to the 1/2 inch (13mm) hook-upat the unit.

This gas fireplace is designed to accept a 1/2 inch (13 mm) gas supply line. To install the gas supply line:

A listed (and Commonwealth of Massachusetts approved) 1/2 inch (13mm) tee-handlemanualshut-offvalve and a listed flexible gas connector are connected to the 1/2 inch (13mm) inlet of the control valve.NOTE: If substituting for these components, please consult local codes for compliance.

Locate the gas line access hole in the outer casing of the fireplace.

The gas line may be run from either side of the fireplace provided the hole in the outer wrap does not exceed 2 1/2” in diameter and it does not penetrate the actual firebox.

The gap between the supply piping and gas access hole can be plugged with non-combustibleinsulation to prevent cold air infiltration.

Open the fireplace lower grille, insert the gas supply line through the gas line hole, and connect it to the shut-offvalve.

When attaching the pipe, support the control so that the lines are not bent or torn.

After the gas line installation is complete, all connections must be tightened and checked for leaks with a commercially-available,non-corrosiveleak check solution. Be sure to rinse off all leak check solution following testing.

!Warning: DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS.

At the gas line access hole, use insulation to re-packthe space around the gas pipe.

Insert insulation from the outside of the fireplace and pack the insulation tightly to totally seal between the pipe and the outer casing.

Step 11. Installing Trim, Logs,

and Ember Material

Installing the Trim

Combustible materials may be brought up to the specified clearances on the side and top front edges of the fireplace, but MUST NEVER overlap onto the front face. The joints between the finished wall and the fireplace top and sides can only be sealed with a 300° F. (149° C) minimum sealant.

WARNING: WHEN FINISHING THE FIREPLACE,

!

NEVER OBSTRUCT OR MODIFY THE AIR INLET/ OUTLET GRILLES IN ANY MANNER.

Install optional marble and brass trim surround kits as desired. Marble, brass, brick, tile, or other non-combustiblematerials can be used to cover up the gap between the sheet rock and the fireplace.

Do not obstruct or modify the air inlet/outlet grilles. When overlapping on both sides, leave enough space so that the bottom grille can be lowered and the trim door removed.

Positioning the Logs

If the gas logs have been factory installed they should not need to be positioned. If the logs have been packaged separately, refer to the instructions that accompany the logs. Save the log instructions with this manual.

If sooting occurs, the logs might need to be repositioned slightly to avoid excessive flame impingement.

Placing the Ember Material

Ember material is shipped with this gas fireplace. To place the ember material:

Pull the four glass latches out of the groove on the glass frame. Remove glass door from the unit (see Figure 33).

Embers CANNOT be placed directly over ports. Care should be taken not to cover the lighting trail of ports (from back to front).

Ε Place dime size pieces of mineral wool embers about 1/2 inch apart near port holes in burner top. Do NOT press embers into burner ports. Cover the top of the burner with a single layer of ember material. For best performance do NOT place embers on the ports at the rear of the burner (Figure 33). Failure to follow this procedure will likely cause lighting and sooting problems.

Step 12. Before Lighting the Fireplace

Before lighting the fireplace, be sure to do the following:

Remove all paperwork from underneath the fireplace. Review safety warnings and cautions

Read the Safety and Warning Informationsection at the beginning of this Installers Guide.

Double-checkfor gas leaks

Before lighting the fireplace, double-checkthe unit for possible gas leaks.

Double-checkvent terminations and front grilles for obstructions.

Before lighting the fireplace, double-checkthe unit for possible obstructions that could be blocking the vent terminations or the front grilles.

Double-checkfor faulty components

Any component that is found to be faulty MUST BE replaced with an approved component. Tampering with the fireplace components isDANGEROUS and voids all warranties.

A small amount of air will be in the gas supply lines. When first lighting the fireplace, it will take a few minutes for the lines to purge themselves of this air. Once the purging is complete, the fireplace will light and will operate normally.

Subsequent lightings of the fireplace will not require this purging of air from the gas supply lines, unless the gas valve has been turned to the OFF position, in which case the air would have to be purged.

NOTE: The fireplace should be run 3 to 4 hours on the initialstart-up.Turn it off and let it cool completely. Remove and clean the glass. Replace the glass and run the fireplace for an additional 8 hours. This will help to cure the products used in the paint and logs.

During this break-inperiod 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 fireplace’s initial burning.

GAP MAINTAINER CLIP

AIR SHUTTER

 

HANDLE

Figure 36.

 

Air Shutter Setting

This fireplace has an adjustable air shutter (which controls the primary air) factory set for the minimum vertical vent run (see Figure 36). If your installation has more than the minimum required vertical vent length, adjustment of the air shutter may be necessary to obtain optimal flame appearance. This should be adjusted by a qualified installer at the time of installation.

The air shutter handle has a gap maintainer clip factory installed which needs to be removed to make any adjustments. By pushing the air shutter handle in, you will be closing the air shutter. Care should be taken when adjusting the air shutter so as not to cause the fireplace to soot. If sooting occurs the air shutter will need to be opened by pulling the handle out.

Step 13. Lighting the Fireplace

You’ve reviewed all safety warnings, you’ve checked the fireplace for gas leaks, you know the vent system is unobstructed, and you’ve checked for faulty components. Now you’re ready to light the fireplace.

!WARNING: PLEASE REFER TO THE USER’S MANUAL FOR ALL CAUTIONS, SAFETY, AND

WARNING INFORMATION PERTAINING TO THE LIGHTING AND OPERATION OF THE FIREPLACE.

After the Installation

!LEAVE THIS INSTALLATION MANUAL WITH THE APPLIANCE FOR FUTURE REFERENCE.

4Maintaining and Servicing Your Fireplace

Fireplace Maintenance

Although the frequency of your fireplace servicing and maintenance will depend on use and the type of installation, you should have a qualified service technician perform an appliance check-upat the beginning of each heating season. See the table below for specific guidelines regarding each fireplace maintenance task.

IMPORTANT: TURN OFF THE GAS BEFORE SERVICING YOUR FIREPLACE.

Replacing old ember material

Frequency: Once annually, during the checkup.By: Qualified service technician.

Task: Brush away loose ember material near the burner. Replace old ember material with newdime-sizeand shape pieces. Save the remaining ember material and repeat this procedure at your next servicing. For more information, see

Placing Ember Material.

Cleaning Burner and Controls Frequency:Once annually. By:Qualified service technician.

Task: Brush or vacuum the control compartment, fireplace logs and burner areas surrounding the logs.

Cleaning Flame Sensor Rod (IPI Systems) Frequency:Annually.

By: Qualified service technician.

Task: Make a visual check of the straight flame sensor rod (see Figure 25). Use emery cloth to carefully remove any existing film or white deposits.

Checking Flame Patterns, Flame Height

Frequency: Periodically.

By: Qualified service technician/Home owner.

Task: Make a visual check of your fireplace’s flame patterns. Make sure the flames are steady - not lifting or floating. The thermopile/thermocouple tips should be covered with flame. See Figure 25.

Checking Vent System

Frequency: Before initial use and at least annually thereafter, more frequently if possible.

By: Qualified service technician/Home owner.

Task: Inspect the external vent cap on a regular basis to ensure that no debris is interfering with the flow of air. Inspect entire vent system for proper function.

Cleaning Glass Door

Frequency: After the first 3 to 4 hours of use. As necessary after initial cleaning.

By: Home owner.

Task: Remove and clean glass after the first 3 to 4 hours of use. After the initial cleaning, clean as necessary, particularly after adding new ember (flame colorant) material. Film deposits on the inside of the glass door should be cleaned off using a household glass cleaner.NOTE: DO NOT handle or attempt to clean the door when it is hot and DO NOT use abrasive cleaners.
