HEARTH HOME CERONA-IFT Series Passive Heat Kit Instruction Manual
CAUTION! Risk of Cuts, Abrasions or Flying Debris.
Wear protective gloves and safety glasses during installation. Sheet metal
edges are sharp
CAUTION! Do not install damaged components.
If any parts are missing or damaged, contact your dealer before starting
installation. DO NOT install a damaged kit.
Introduction
The Passive Heat (PH-CERONA) Heat Management System conveys warm air from the fireplace into the same room through either one front discharge slot, two side discharge heat registers or an open top discharge.
Installation of the Passive Heat kit must be done in conjunction with the appliance installation. Installation of this kit MUST be performed by a qualified service technician.
WARNING! Risk of Fire! DO NOT install the Passive Heat (PH-CERONA) Heat Management System with models that are not approved. Overheating will occur. Side Discharge Passive Heat systems require the use of the Register Cover Kit (PH-SIDETRIM), which must be purchased separately, to complete the installation. Contact your dealer to order the kit.
Passive Heat Trim Kits are also available for installation with the Front Discharge Passive Heat system which must be purchased separately. Contact your dealer to order the appropriate kit: PH-FRTTRIM-36 or PH-FRTTRIM-42. Follow instructions included with the trim kit to complete installation of the Passive Heat system.
The Passive Heat kit is tested and safe when installed in accordance with this installation manual. It is your responsibility to read all instructions before starting installation and to follow these instructions carefully during installation.
The Passive Heat kit is carefully engineered and must be installed only as specified. If you modify it or any of its components you will void the warranty, and you may possibly cause a fire hazard. Installation must be done according to applicable local, state, provincial, and/or national codes.
Preparation
Plan the location of the appliance.
Determine whether front, open top or side discharge is to be installed and
follow instructions for the appropriate application
CAUTION! Risk of Burns!
- The appliance should be turned off and cooled before kit is installed.
- Shut off gas supply
Power Vent Option
If an optional power vent will be installed in conjunction with the Passive Heat Kit (PH-CERONA), Hearth & Home Technologies recommends the PVLP-SLP or PVV-SLP power vent options. If the application does not allow for the PVLP-SLP or PVV-SLP to be used, the PVI-SLP-B may be used. The PVI-SLP-B must be mounted outside the chase due to the higher noise level created

Clearances
WARNING! Risk of Fire! Maintain clearances to combustibles as specified
Ensure all clearances are maintained.
- Maintain minimum distance from top of appliance opening to the room ceiling. Refer to the figures in the Framing section of this instruction.
- An open space, or “cavity,” is allowed up to three inches above the top of the passive heat discharge opening. A chase ceiling is required when the open space “cavity” exceeds three inches above the discharge opening. Construct the false ceiling from material such as metal, drywall or plywood
Clearance – Sprinkler to Passive Heat
Figure 2 references the clearances that must be adhered to when installing a
sprinkler head near a passive heat discharge opening.
Figure 2 Sprinkler Head Clearance
-
If the distance from the top of the passive heat front discharge opening to the ceiling is 36 inch or greater, then there is no 36 inch clearance requirement. This is for a ceiling sprinkler head installation only.
Note: When installing a sprinkler head near a heat discharge opening, it is recommended to use a sprinkler head with an Extra High sprinkler activation temperature rating. -
When installing a sprinkler head exterior of the chase, maintain the following clearances to discharge openings (convection slots, passive heat registers, heat zone registers, etc.): 36 inch top, 18 inch sides and 6 inch bottom.
-
DO NOT install a sprinkler head inside a chase that is set up for passive heat.

Adapter Installation
Front, Side and Open Top Discharge
CAUTION! Risk of Cuts, Abrasions or Flying Debris. Wear protective gloves and safety glasses during installation. Sheet metal edges are sharp
-
Remove both top knockouts from outer wrap as shown in Figure 7. Discard knockout piece and ensure no other material or debris is blocking the hole created by removing the knockout.
-
Remove both insulation plugs from insulation blanket visible through top knockout openings. Discard insulation plugs and ensure no other material or debris is blocking the hole created when removing insulation plug.
-
Center adapter over opening with the solid portion facing the front of the appliance. Attach both adapters to appliance by installing three screws per adapter. See Figure 8.
Note: If installing an additional Heat Management System, refer to the instructions included with the kit for further installation instructions.
Passive Heat Template
Front and Side Discharge
Install the passive heat templates to prevent finishing material from being installed over passive heat discharge openings. Use two templates for front discharge and four templates for side discharge.
-
Hand bend templates as shown in Figure 9.
-
Place one template into the top left corner of the discharge opening as shown in Figure 10. Align the outside edge of the framing with the notch in the template as shown in Figure 11. Attach to framing using wood screws.
- Place the second template into the bottom right corner and attach using the same method as in Step 2. If installing templates on framing for a side discharge kit, repeat the process for the additional two templates on the other side discharge opening.
- Once the wall finishing material has been installed, remove the templates and discard. After the templates have been removed, the trim kit, register, or other finishing options may be installed.
Finishing
-
Apply wall sheathing material, such as drywall up to 1/2 in. (13mm) thick up to the edge of the discharge opening.
WARNING! Risk of Overheating! DO NOT apply wall sheathing past the edge of discharge opening or finishing templates. Remove finishing templates before appliance operation. Overheating of appliance and combustible materials will occur -
Facing Material with Front Trim Kit (PH-FRTTRIM)
1 Inch Thick or Less: When using Non-Combustible facing material in this thickness range, the Overlap Fit method may be used. Place facing materials up to the edge of the discharge opening and install trim kit as instructed. Facing must not interfere with the air flow through the trim kit.
Greater than 1 Inch: Non-Combustible facing material in this thickness range must use the Inside Fit method. Place facing materials up to ½ in. (13mm) away from the edge of the trim kit to allow for proper removal of the vent cover. Install trim kit as instructed. Consult the appliance Installation Manual to determine maximum facing material thickness. -
Facing Material with Side Discharge (PH-SIDETRIM)
1 Inch Thick or Less: When using Non-Combustible facing material in this thickness range, the Overlap Fit method may be used. Place facing materials up to the edge of the discharge opening and install register covers as instructed. Facing must not interfere with the air flow through the trim kit.
Greater than 1 Inch: Non-Combustible facing material in this thickness range must use the Inside Fit method. Place facing materials up to the edge of the register covers. Install register covers as instructed. Consult the units Installation Manual to determine maximum facing material thickness. -
Install trim kit (PH-FRTTRIM or PH-SIDETRIM) as instructed.
Side Discharge: The PH-SIDETRIM kit is required to complete installation.
Front Discharge: The PH-FRTTRIM kit is an optional finishing method. Other standard finishing methods may be used as well.
Painting
The location of the Passive Heat discharge opening could allow for venting and
other construction materials to be visible. It is recommended to paint the
vent pipe, firestop, and other visible construction materials, as shown in
Figure 12, using a high temperature paint with a minimum of 300 °F continuous
exposure rating. Hearth & Home Technologies recommends using black touch up
paint (part number TUP-GBK-12) available from your Hearth & Home Technologies
dealer.
