2 Getting Started
A. Design and Installation Considerations
WARNING! Risk of Fire or Explosion! Read all instructions before starting the installation.
Direct vent gas appliances are designed to operate with all combustion air siphoned from outside of the building and all exhaust gases expelled to the outside. No additional outside air source is required.
Installation MUST comply with local, regional, state and national codes and regulations. Consult insurance carrier, local building inspector, fire officials or authorities having jurisdiction over restrictions, installation inspection and permits.
Before installing, determine the following:
· Where the appliance is to be installed.
· The vent system configuration to be used.
· Gas supply piping requirements and space for access. See Section 9 Gas Information.
· Provisions for optional heat management system. If Passive Heat will be installed, consider location of discharge opening in relation to venting and other construction materials. Refer to the installation instructions included with the Passive Heat kit for details and the appropriate sections in this manual in terms of clearances and framing (Section 3), and finishing and mantels (Section 10).
· Electrical wiring requirements.
· Framing and finishing details.
· Whether optional accessories–devices such as a fan, wall switch, or remote control–are desired. See Section 12.B for approved accessories.
Installation and service of this appliance should be performed by qualified personnel. Hearth & Home Technologies recommends HHT Factory Trained or certified professionals.

B. Good Faith Wall Surface/TV Guidelines
NOTICE: Surface temperatures listed above are taken with a temperature measuring probe as prescribed by the test standard used for appliance certification. Temperatures on walls or mantels taken with an infrared thermometer may yield increased temperatures of up to 30 °F (17 °C) or more depending on the thermometer settings and material characteristics being measured. Use appropriate finishing materials that are able to withstand these conditions. For additional finishing guidelines, see Section 10. Surface temperatures will vary due to factors such as ceiling height, room size and installation configuration.

D. Constructing the Appliance Chase
NOTICE: Install appliance on hard metal or wood surfaces extending full width and depth. DO NOT install directly on carpeting, vinyl, or any combustible material other than wood. WARNING! Risk of Fire! Maintain specified air space clearances to appliance and vent pipe: · Insulation and other materials must be secured to prevent
accidental contact. · The chase must be properly blocked to prevent blown
insulation or other combustibles from entering and making contact with fireplace or chimney. · Failure to maintain airspace may cause overheating and a fire.
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.
NOTICE: Where required by code, install only sprinkler heads with a sprinkler activation temperature classified as Extra High. · Sprinklers inside of chase: Keep sprinkler head away
from vent and chimney. · Heat Management applications: Maintain 36 inches
(914 mm) of clearance to openings from which heat is discharged such as convection slots, passive heat registers, heat zone registers, etc. Refer to Section 6.B for Heat Management options allowed for this appliance.
Chases should be constructed and insulated in the same manner as the thermal envelope of the home based on the code requirements for that climate zone to prevent air leakage and draft problems. The chase is an extension of the building thermal envelope.
To further prevent drafts and air leakage, the wall shield and ceiling firestops should be sealed with caulk with a minimum of 300 ºF (149 ºC) continuous exposure rating to seal gaps. Gas line holes and other openings should be sealed 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.
Minimum height requirements for an exterior chase on a topvented appliance are shown in Figure 3.14. Reference Figure 4.5 for additional clearances.

Heat & Glo · 6KX-AU Installation Manual · 2589-980 Rev. B · 5/23

E. Floor Protection
Vinyl Flooring
Vinyl flooring is sensitive to heat. To avoid damage to the vinyl flooring, a 12 in (305 mm) minimum x 12 in (305 mm) minimum hearth is recommended when using vinyl flooring up to the wall. See Figure 3.15. If no hearth is used, it is recommended to provide a minimum of 30 In (762 mm) inches of clearance in front of the appliance to the vinyl flooring OR the bottom of the appliance should be raised a minimum of 24 in (610 mm) off of the floor to allow the vinyl flooring to be installed up to the wall.
NOTICE: Clearances that do not meet the minimum guidelines could result in damage or buckling to the vinyl flooring and is done at the installer’s risk.
Hearth and Home Technologies does not recommend adhesive based vinyl flooring products due to thermal expansion during operation. Floating style flooring can be used, but will reach temperatures up to 110 °F (43 °C) (based on ambient temperature of 70 °F (21 °C). Consult the manufacturer’s flooring specifications to ensure compatibility.

E. Vent Diagrams
General Rules:
· When penetrating a combustible wall, a wall shield firestop must be installed.
· When penetrating a combustible ceiling, a ceiling firestop must be installed.
· Horizontal runs of vent do not require vertical rise; horizontal runs may be level.
· It is recommended that the horizontal termination cap have a 1/4 inch (6 mm) downward slant to allow any moisture in cap to be released. See Figure 4.8.
If venting configuration differs from the vent diagrams on the following pages (Figure 4.12-4.27), these rules also apply:
· SUBTRACT 3 ft (914 mm) from the total H measurement for each 90º elbow installed horizontally.
· SUBTRACT 1-1/2 ft (457 mm) from the total H measurement for each 45º elbow installed horizontally.
· A maximum of three 90º elbows (or six 45º elbows) may be used in any vent configuration. Some elbows may be installed horizontally. See Figure 4.13.
· Elbows may be placed back to back anywhere in the system.
· Any 90º elbow may be replaced with two back to back
45º elbows.
· 2 x 45° elbow jog directly off the top of the fireplace is allowed but has no V or H value and DOES NOT count towards total elbow count.

WARNING
Fire Risk. Explosion Risk. Do NOT pack insulation or other combustibles between ceiling firestops. · ALWAYS maintain specified clearances around
venting and firestop systems. · Install wall shield and ceiling firestops as speci-
fied. Failure to keep insulation or other material away from vent pipe may cause fire.
WARNING
Fire Risk. · When using DVP-HRC-SS and DVP-HRC-ZC-
SS termination caps on top vented fireplaces, a 6 inch (152 mm) minimum vertical vent section is required before installing first elbow.

A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to vent. DO NOT pack insulation or other combustibles:
· Between ceiling firestops · Between wall shield firestops · Around vent system Failure to keep insulation or other material away from vent pipe could cause overheating and fire.
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm). · DVP heat shield – designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick. · If wall thickness is less than 4 in. (102 mm) the existing heat shields must be field
trimmed. If wall thickness is greater than 7-1/4 in. (184 mm) a DVP-HSM-B will be required.

To Install Elbow Heat Shield:
1. Remove the elbow heat shield from the shipping position by removing screws.
2. Fasten the shield in place using the four pilot holes. The shield should be oriented such that the dimension (longest dimension) is running in the same direction the elbow is pointing. The shield should be centered directly above the elbow, and positioned so that it creates a 1/2 in. (13 mm) airspace between the shield and the combustible surface. See Figure 5.2.

Elbow Heat Shield
WARNING! Risk of Fire! Elbow heat shield MUST be installed if required. Overheating will occur.
Top vented appliances: Installation of the elbow heat shield is required when the clearance to combustible material above the first 90 degree vent elbow is three inches or less. See Figure 5.1.
Note: A minimum of three inches (76 mm) clearance from the top of the pipe to any combustible material must always be maintained.
To Install Elbow Heat Shield:
1. Remove the elbow heat shield from the shipping position by removing screws.
2. Fasten the shield in place using the four pilot holes. The shield should be oriented such that the dimension (longest dimension) is running in the same direction the elbow is pointing. The shield should be centered directly above the elbow, and positioned so that it creates a 1/2 in. (13mm) airspace between the shield and the combustible surface. See Figure 5.2.

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.
Whenever a non-combustible wall is penetrated, the wall shield firestop is only required on one side and no heat shield is necessary.

B. Wall Penetration Framing/Firestops
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 is required on one side only on interior walls. If your local inspector requires a wall shield firestop on both sides, then both wall shield firestops must have a heat shield (refer to Section 12.A.) attached to them.
· 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.
Whenever a non-combustible wall is penetrated, the wall shield firestop is only required on one side and no heat shield is necessary.
DO NOT PACK VENT FRAMING HOLE WITH INSULATION OR OTHER MATERIAL.

A ceiling firestop MUST be used between floors and attics.
· DVP pipe only – Frame an opening 10 in. by 10 in. (254 mm by 254 mm) whenever the vent penetrates a ceiling/floor (see Figure 5.5).
· Frame the area with the same sized lumber as used in ceiling/floor joist.
· The ceiling firestop may be installed above or below the ceiling joists when installed with an attic insulation shield. It must be under joists between floors that are not insulated. See Figure 5.6.
· Secure in place with nails or screws.
WARNING! Risk of Fire! DO NOT pack insulation around the vent. Insulation must be kept back from the pipe to prevent overheating.

WARNING! Risk of Fire! DO NOT block passive heat registers! Overheating of appliance and combustible materials will occur. WARNING! Risk of Fire! DO NOT remove a knockout unless a heat management system will be installed in its place. Appliance and combustible materials will overheat.
Introduction
An optional heat management system allows the heat from the appliance to be redirected as desired.
An optional heat management system must be installed by a qualified service technician at the time of the appliance installation. Follow the instructions shipped with the kit for installation and operation.
Heat Management System options are:
· HEAT-ZONE®-240V: The heat is diverted into an adjacent room. The HZMR-ADP Heat-Zone Adapter kit may be required and is ordered separately. See Table 6.1.
· Passive Heat (PH-MR): The heat is vented into the room in which the appliance is installed through a discharge opening(s).
NOTICE: Additional clearances are required for heat management systems installations. Provisions must be made in advance to ensure fit within the framing.
· Determine the heat management system(s) that will be installed.
· Locate the two heat management knockouts on the top of the appliance. Remove the knockout from the fireplace and discard it. See Figure 6.12. Either one or two heat management systems may be installed. Remove the knockout(s) from the appliance with a tin snips.
· Center the duct collar around the exposed hole and attach it to the appliance with 3 screws.
Note: Do this BEFORE final positioning of the appliance.
· Determine the location for the air register/fan housing assembly.
Reference the appropriate instructions included with the kit for the remaining installation steps.

These models may utilize two Heat Management Systems, but not all are compatible.
Passive Heat may be used with HEAT-ZONE®-240V. The dedicated knockouts, as shown in Figure 6.12, must be used only as indicated.
Note: When a fan is operated with the Passive Heat system, there will be a decrease in the amount of air flowing from the appliance opening. Air will be flowing from both the appliance opening and the passive heat opening.
