C. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the gas appliance and/or its vent system. In cooler climates the vent should be enclosed inside the chase.
NOTICE: Treatment of ceiling firestops and wall shield firestops 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, you MUST check local building codes to determine the requirements to these steps.
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, in regions where cold air infiltration may be an issue, the inside surfaces may be sheetrocked and taped (or an equivalent method may be used) to achieve maximum air tightness.
12
To further prevent drafts, the wall shield and ceiling firestops should be caulked with caulk with a minimum of
300 ºF (149 ºC) continuous exposure rating to seal gaps.
Gas line holes and other openings should be caulked with caulk with a minimum of 300 ºF (149 ºC) continuous exposure rating or stuffed with unfaced insulation. If the appliance is being installed on a cement surface, a layer of plywood may be placed underneath to prevent conducting cold up into the room.
Note: Figure 3.7 and Figure 3.8, and Figure 3.9 show the fireplace installed on the floor. However, this fireplace can be elevated off the floor provided that the fireplace is properly supported by framing materials and the ceiling clearances are maintained.

C. Approved Pipe
This appliance is approved for use with Hearth & Home
Technologies DVP venting systems. Refer to Section
12.A for vent component information and dimensions.
DO NOT mix pipe, fittings or joining methods from different manufacturers.
The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each joint within the wall.
WARNING! Risk of Fire or Asphyxiation. This appliance requires a separate vent. DO NOT vent to a pipe serving a separate solid fuel burning appliance.
D. Use of Elbows
Diagonal runs have both vertical and horizontal vent aspects when calculating the effects. Use the rise for the vertical aspect and the run for the horizontal aspect (see
Figure 4.4).
Two 45º elbows may be used in place of one 90º elbow.
On 45º runs, one foot of diagonal is equal to 8-1/2 in. (216 mm) horizontal run and 8-1/2 in. (216 mm) vertical run. A length of straight pipe is allowed between two 45º elbows.
See Figure 4.4.

E. Measuring Standards
Vertical and horizontal measurements listed in the vent diagrams were made using the following standards:
• Pipe measurements are shown using the effective length of pipe. See Section 12.A for information on effective length of pipe components.
• Measurements are made from the appliance outer wrap, not from the standoffs.
• Horizontal terminations are measured to the outside mounting surface (flange of termination cap). See
Figure 4.3.
• Vertical terminations are measured to bottom of termination cap.
• Horizontal pipe installed level with no rise.
F. Exhaust Restrictor Instructions
Exhuast Restrictor is only used with vent runs 8 ft.

Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must frame a hole for the wall shield firestop(s). The wall shield firestop maintains minimum clearances and prevents cold air infiltration.
• The opening must be framed on all four sides using the same size framing materials as those used in the wall construction.
• DVP pipe - A wall shield firestop must be placed on each side of an interior wall. A minimum 1-1/2 in. (38 mm) overlap of attached heat shields must be maintained.
• See Section 7.F. for information for regarding the installation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by non-combustible materials such as concrete, a hole with diameter one inch greater than the pipe is acceptable.
Note: Do not pack the gap with insulation.
Whenever a non-combustible wall is penetrated, the wall shield firestop is only required on one side and no heat shield is necessary.

Splatter Guard
The splatter guard is a piece of corrugated material used to protect the appliance during the installation process before finishing work on the whole hearth is complete. A splatter guard is factory-installed on
MEZZO-AU models. Splatter guards must be removed before appliance is fired.
WARNING! Risk of Fire! Remove the splatter guard before lighting the appliance. Shut off gas to the appliance when the splatter guard is in place to prevent accidental operation.
Finishing Instructions
It is important to follow the framing and finishing instructions to ensure proper placement of fireplace into the surrounding framing / finishing materials.
Wall sheathing materials 10 mm thick are specified in this installation manual to properly align with the factory-installed non-combustible material.
WARNING! Risk of Fire! DO NOT remove the installed non-combustible board or cover it with combustible material, such as:
• Drywall (gypsum board)
• Plywood
• Materials that do not meet the ASTM E 136 Non-combustibility standard (below).
Removal of installed, non-combustible board and/or use of materials not meeting the ASTM E 136 standard could cause fire.
Non-Combustible Materials Specification
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 ºC.
WARNING! Risk of Fire! Maintain specified air space clearances to combustibles. Inadequate air space could cause overheating and fire.
Finishing Materials
NOTICE: The maximum finishing material not only includes the decorative finish materials (marble, tile, slate, etc) but also the thin set, lath and adhesive used to attach the decorative finish material.
WARNING! Risk of Fire! DO NOT use screws longer than two inches when attaching finishing materials to installed non-combustible material. Screws longer than two inches will compromise clearance and could cause overheating and fire.
WARNING! Risk of Fire, Explosion or Asphyxiation!
DO NOT use screws more than one inch long on lower cover panel. Longer screws may penetrate gas line or damage valve or electrical components.
This section discusses installation details associated with the Inside and Overlap Fit methods and specifies additional non-combustible materials required.
When finishing the wall around the fireplace, it is critical that wall sheathing be fastened properly. Wall sheathing fasteners, such as screws or nails, are not permitted in some locations. See Figure 10.1.
It is acceptable to pre-drill holes and use self-tapped screws in the installed non-combustible board which may be used to lathe (a backer for tile, marble, etc.). Screws being installed through the installed non-combustible board should be self-tapping type with a maximum length of 2 in. (51 mm) See Figure 10.1.
When installing finish material on the lower cover panel,
DO NOT drill or install screws longer than one inch.
Screws longer than one inch could penetrate the lower cover panel causing damage to components or penetrate the gas line. One inch screws are included in the manual bag assembly that are intended for use when attaching finishing material to lower cover panel. See Figure 10.1.

E. Install Media
A media kit is included with the MEZZO-AU models. Install rock media according to these instructions.
WARNING! Choking Hazard! Keep media out of reach of children.
CAUTION! Risk of Burns! The fireplace should be turned off and cooled before media is installed.
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp.
Cleaning the Media
During shipment of the media, dust and debris can accumulate. It is recommended that the media be rinsed thoroughly with water to remove dust and small particles.
An easy method to clean the media is to place the media into a pail and rinse thoroughly. Spread the media out over paper towels and allow the media to dry before installing them into the fireplace.
INSTALLATION
1. Choose 7 - 10 round pieces of media approximately
1/2 in. (13 mm) in size and set them aside. These will be used later to conceal the pilot end of the burner.
Reference Figure 11.6 for choosing round pieces of glass.
WARNING! Risk of Explosion! DO NOT put any flat media pieces larger than 1/2 in. (13 mm) in diameter near pilot. Delayed ignition could occur. Use only round 1/2 in.
(13 mm) pieces near pilot.
WARNING
Delayed Ignition Risk
• Place media according to instructions.
• Do NOT place media in area in front of pilot
• Do NOT place media in a position that they may fall into area in front of pilot.
• Do NOT use any media other than the media supplied with this fireplace.
• Do NOT exceed one layer of media on base pan.
Fireplace will not function properly.
Delayed ignition may occur.

TROUBLESHOOTING
After the initial start up burn, it may be necessary to adjust the media placement to achieve the best flame appearance. While flame height variation is normal, there may appear to be higher peaks in some areas and low flame peaks in other areas.
If the flame height appears to be excessively high in some spots, applying more media to these areas on top of the burner will help even out the flames. Spreading the media as evenly as possible is the most effective way to achieve optimal flame appearance and the most even flame heights. One or more test burns may be required to watch the flames mature and see how even they look before making adjustments.
Avoid using media pieces larger than two inches in diameter, these can be disruptive to the flame patterns. If you find exra large media pieces, discard.
F. Install Log Set
An optional log set is available for use with the MEZZO-
AU models. Install the log set per instructions included with kit.
G. Appliance Operation
Start the appliance to verify proper function and installation. See the appliance Owner’s Manual for IPI lighting instructions.
