The New Buck Corporation room heater Model 20 is one of the safest and most efficient heating systems

available when installed and operated as specified in these instructions and as stipulated on the operation and

installation labels affixed to the unit. The unit is designed to burn wood fuel only.

Please read this entire manual before you install and use your new room heater. Failure to follow instructions may

result in property damage, bodily injury, or even death.

Throughout the manual, you will see this symbol . This indicates areas of importance regarding safety.

Please make a special note of these areas.

Install and use only in accordance with the manufacturer’s installation and operating instructions. Do not connect

this unit to a chimney flue serving another appliance.

ROOM HEATER FEATURES

Before attempting to install or operate your heater, it is a good idea to familiarize yourself with the features and

operating controls of the unit.

OPERATING CONTROLS

WARNING: Model 20 heater was not designed for fire grates.

1. Bypass Damper: The bypass damper control is located in the top center of the heater front just under the top.

It is operated by pushing or pulling the rod. The damper is fully open when the handle is pulled out and fully

closed when it is pushed in. The damper must be open before the door is opened.

2. Blower Control: The blower control switch is located behind the access door at the lower left hand side of

the front of the unit. The unit has a Auto-Off-Manual manual switch. Set the switch to the Manual position and

the blower well start at any temperature, set the switch to the Off position and the blower well not run at any

temperature. Set the switch to the Auto position and when the stove temperature reaches 110oblower will

automatically come on.

3. Primary Air Control: The primary air intake draft control is located on the upper portion of the unit next to

the top extension. It is operated by moving up and down to control the amount of primary air entering the

firebox.

4. Warm Air Outlets: Provides heat extraction from the top of the firebox.

5. Baffles: Directs air flow around the unit for maximum heat transfer.

6. Air Inlet: Allows cool air near the floor to be circulated through the blower and back into the warm air

chamber of the heater.

7. Stand: Elevates heater above the floor for safety and a neat appearance.

8. Door: Provides an “airtight” feature. The door allows a much higher burning efficiency than can be obtained

with an open firebox.

9. Hearth Extension: Offers protection from spilled ashes and cinders.

10. Power Cord: Provides electrical power to operate the blower.

11. Chimney Connector: Used to connect unit to chimney or direct connect kit.

12. Catalysts: Enables the unit to burn cleanly and efficiently.

13. Temperature Monitor: The location can be used for either a fireplace insert or freestanding installation.

Monitor hole is located to the right of the damper rod on the front. Remove plug and insert probe provided by

manufacturer.

14. Cover Door: Conceals blower, blower controls and ash pan.

15. Air Wash: Primary air is directed in such a way as to provide a “sweeping” airwash over the glass to assist in

keeping it clean.

16. Ash Pan: Provides for easy ash removal

17. Outside Air Control: Allows for adjustment of the amount of outside air entering the unit (installations using

outside air kit #P21B). Required in Mobile Home Installation.

EPA COMPLIANCE STATUS

This manual describes the installation and operation of the New Buck Corporation, Model 20 wood heater.

This heater meets the U.S. Environmental Protection Agency’s Emission limits for wood heaters sold after July

1, 1992. Under specific test conditions this heater has been shown to deliver heat at rates ranging from

approximately 10,000 to 39,000 BTU/hr.

CATALYST EQUIPPED

This wood heater contains a catalytic combustor, which needs periodic inspection and replacement for proper

operation. It is against the law to operate this wood heater in a manner inconsistent with operating instructions

in this manual, or if the catalytic element is deactivated or removed.

CATALYST WARRANTY

The combustor supplied with this heater is a set of (2) (2x3-5/16x7x25 cells). Consult the catalytic combustor

warranty also supplied with this heater. All warranty claims should be addressed to:

Applied Ceramics

Customer Service Department

P.O. Box 29664

Atlanta, GA 30359

770-448-6888

See enclosed catalyst warranty for instructions. New Buck Corporation does not handle catalyst replacements.

Customer can order direct from Applied Ceramics.

PROPER FUEL SELECTION

This heater is designed to burn natural wood only. Higher efficiencies and lower emissions generally result

when burning air dried seasoned hardwoods, as compared to softwoods or to green or freshly cut hardwoods.

DO NOT BURN:

1) Treated Wood 3) Garbage 5) Solvents 7) Trash

2) Coal 4) Cardboard 6) Colored Paper

Burning treated wood, garbage, solvents, colored paper or trash may result in release of toxic fumes and may

poison or render the catalytic combustor ineffective.

Burning coal, cardboard, or loose paper can produce soot, or large flakes of char or fly ash that can coat the

combustor, causing smoke spillage into the room and rendering the combustor ineffective.

ACHIEVING CATALYTIC LIGHT-OFF

The temperature in the stove and the gases entering the combustor must be raised to between 500o F to 700oF

for catalytic activity to be initiated. This can be determined with the use of a temperature monitor (TM-20).

During the start up of a cold stove a medium to high firing rate must be maintained for about 20 minutes. This

ensures that the stove, catalyst, and fuel are all stabilized at proper operating temperatures. Even though it is

possible to have gas temperatures reach 600o F within two to three minutes after a fire is started, if the fire is

allowed to die down immediately it may go out or the combustor may stop working. If this happens open the

damper to raise the temperature to activate the catalyst. Once the combustor starts working, heat generated in

it by burning the smoke will keep it working.

ACHIEVING CATALYTIC LIGHT-OFF WHEN REFUELING

During the refueling and rekindling of a cool fire, or a fire that has burned down to the charcoal phase, operate

the stove at a medium to high firing rate for about 10 minutes to ensure that the catalyst reaches approximately

600o F.

CATALYST MONITORING

It is important to periodically monitor the operation of the catalytic combustor to ensure that it is functioning

properly and to determine when it needs to be replaced. A non-functioning combustor will result in a loss of

heating efficiency, and an increase in creosote and emissions. Following is a list of items that should be

checked on a periodic basis.

Combustors should be visually inspected at least three times during the heating season to determine if physical

degradation has occurred. Actual removal of the combustor is not recommended unless more detailed

inspection is warranted because of decrease in performance. If any of these conditions exist, refer to Catalyst

Troubleshooting Section of the owner’s manual.

This catalytic heater is equipped with the means to install a temperature probe to monitor catalyst operation.

Properly functioning combustors typically maintain temperatures in excess of 1000oF. If catalyst

temperatures are not in excess of 500o F refer to Catalyst Troubleshooting section of this owner’s manual. You

can get an indication of whether the catalyst is working by comparing the amount of smoke leaving the

chimney when the smoke is going through the combustor and catalyst light-off has been achieved to the

amount of smoke leaving the chimney when the smoke is not routed through the combustor (bypass mode).

Step 1—Light stove in accordance with instructions.

Step 2—With smoke routed through the catalyst, go outside and observe the emissions leaving the

chimney.

Step 3—Engage the bypass mechanism and again observe the emissions leaving the chimney.

Significantly more smoke should be seen when the exhaust is not routed through the combustor (bypass

mode). Be careful not to confuse smoke with steam from wet wood.

CAUTION AGAINST OVER-FIRING

Do Not Over-fire This Heater.

Attempts to achieve heat output rates that exceed heater design specifications can result in permanent damage

to the heater and to the catalytic combustor.

MAINTAIN PROPER DRAFT

Draft is the force which moves air from the appliance up through the chimney. The amount of draft in your

chimney depends on the length of the chimney, local geography, nearby obstructions, and other factors. Too

much draft may cause excessive temperatures in the appliance and may damage the catalytic combustor.

Inadequate draft may cause backpuffing into the room and “plugging” of the chimney or the catalyst.

Inadequate draft will cause the appliance to leak smoke into the room through appliance and chimney

connector joints.

An uncontrollable burn or a glowing red stove part or chimney connector indicates excessive draft.

ASH REMOVAL

Whenever ashes build up in the firebox and when the fire has burned down and cooled, remove excess ashes.

Leave an ash bed approximately 1 inch deep on the firebox bottom to help maintain a hot charcoal bed.

Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be

placed on a non-combustible floor or on the ground, away from all combustible materials, pending final

disposal. The ashes should be retained in the closed container until all cinders have thoroughly cooled.

SECTION II

MASONRY INSERT INSTALLATION

INSTALLATION PRECAUTIONS

Extensive field and laboratory testing has shown that catalytic stoves perform best as fireplace inserts when:

1. A direct connect kit is used to connect the stove exhaust outlet directly to the masonry flue of the fireplace

when flue liner size is approximately the same size as the heater flue gas exit. A rain cap is also recommended

to keep flue dry thus allowing a hotter draft.

NFPA 211 CODE: The National Fire Protection Association code requires all fireplace insert heaters to be

positively connected from the heater to the flue liner (subject to State and Local codes in your area).

2. An equivalent sized flue liner is installed when the flue liner size is larger than the heater flue gas exit.

Connection must be from stove exhaust outlet extending the full height of the chimney and must include a rain

cap.

3. Location of chimney is interior (not on an outside wall).

Satisfactory results have been reported with installations other than as listed above. However, as all chimneys draw

differently, problems with performance may be encountered if steps are not taken to keep the chimney hot. A draft

between .03 and .06 inches of water is recommended for proper catalytic operation.

Use the following to complete the installation of the unit as an insert:

Kit #FP20

INSTALLATION (Fireplace Insert)

FIGURE 1 FIREPLACE INSERT

MINIMUM CLEARANCES:

The Model 20 Fireplace Insert is intended for installation in accordance with the standard for chimneys, fireplaces,

vents, and solid-fuel burning appliances, NFPA-211 Code. This model is not intended for installation into factory-

built metal fireplaces or for use with a metal chimney (except as listed in Section V of this manual).

1. The hearth must be of masonry construction and must extend a minimum of 16” in front of the firebox

opening and a minimum of 8” to either side of the firebox opening.

2. If there is not 16” from the front of the firebox opening and the front of the masonry hearth, a floor

protector must be used in front of the hearth to protect combustible materials. 2” of brick, a listed “floor

protector” or a floor protector made of non-combustible, inorganic material with a K* factor may be used

as follows:

K = 2.5 BTU/((HR) (Ft2) (oF/IN))

ALTERNATE FLOOR PROTECTORS MATERIALS

With the floor protector or hearth extension material specified as one layer of 2” thick brick with a K* factor of

5.0, you may use alternate materials as long as the K* factor (s) is calculated as follows:

Formula: Required thickness = (K of alternate material/K of millboard) x (thickness of millboard)

Example: An alternate inorganic non-combustible millboard with a K of .9375 would require a thickness

as follows:

Required thickness = (.9375/5.0) x 2 in.

= 3/8 inch

K Factors of Alternate Materials

Material K Required Thickness

Ceroform 126 .21 1/8”

Limestone 8.0 3.2”

Concrete 8.0 3.2”

Sandstone 13.0 5.2”

Marble 18.0 7.2”

Hearth extension or floor protector thickness above four (4) inches is generally not acceptable due to cost, floor

load capacity, and look. The alternate we recommend is using Ceroform No. 126 millboard 1/8” thick minimum

and putting any type decorative brick or stone (any thickness) on top of it.

• The K* factor represents the thermal conductivity of a material and is the time rate of heat flow through a

homogeneous material under steady-state conditions, through unit area, per unit temperature gradient in the

direction perpendicular to a surface.

3. If your fireplace has wood trim above it, the wood trim must be at least 8” above the top of the unit and

may be a maximum of 1/2” thick.

4. If your fireplace has a wood mantel, the mantel or mantel supports must be located at a height greater

than 12” above the top of the unit.

REQUIRED FIREPLACE DIMENSIONS

Minimum and/or maximum fireplace dimensions:

Height Width Depth

Min. Max. Min. Max. Min.

Model 20 22” 31” 26” 41” 16”

POSSIBLE TOOLS NEEDED FOR INSTALLATION

If you decide to install your own stove, there are several hand tools you may need to do the job. If you do not

already have them, they are readily available at most hardware stores.

Caulking gun

Large adjustable wrench (may not be needed)

Drop cloths or newspapers

Vacuum cleaner or whisk broom

Flashlight

1 tube of RTV silicone, Code 103 or 106, or high temperature rubber cement rated between 450oF- 600o F

7/32” drill bit and drill

Socket/Rachet Set

INSTALLATION PREPARATION

Fireplace:

1. Locate furniture and other materials away from the front of the fireplace to allow free access to the fireplace.

2. Cover the hearth and adjacent floor areas with the drop cloths to protect from soiling or marring the surface.

3. Remove the existing fireplace damper plate.

4. Thoroughly clean the fireplace of ashes and soot.

5. Check the chimney and smoke chamber for excessive buildup of creosote or soot. Also, check for

obstructions, such as bird’s nests. If the chimney is excessively dirty, clean it, or have someone clean it

professionally BEFORE installing or using the room heater.

6. If the fireplace has an ash dump or outside air provision, these must be sealed off with metal or tightly packed

non-combustible insulation to prevent cold air from entering the fireplace chamber.

Heater:

1. Inspect the unit for any obvious physical damage.

2. Plug the power cord into a 115V AC outlet. Set switch to “Manual” and rheostat to “High” position to ensure

motor operates properly.

3. Check the primary air draft control to ensure that it operates freely.

4. Check the operations of the damper control to ensure it will open and close properly.

5. If unit is a fireplace insert remove rear side panels and place screws back in the holes before setting the unit in

the fireplace opening.

NOTE: Due to the redesign for the 2002 series of the Model 20/ZC20, starting

with serial number 003908 . The following steps must be followed for proper in-

stallation and operating.

INSTALLATION

MOUNTING TRIM PANELS FOR MASONRY INSTALLATION

(Changes refer to pages 9 and 10 in your owners manual)

POSITIONING THE HEATER

When positioning the heater, the following conditions

MUST be met! (See Figure 2)

1. The front of the damper opening must be positioned

BEHIND the rear edge of the lintel to ensure proper

draft. (See Figure 2)

2. The vertical plane of the fireplace front must fall

BEHIND the side cold air vent on top of the unit. (In

other words, it is possible to have the heater too far in

as well as not far enough.)

3. Center the heater in the fireplace opening.

MOUNTING THE TRIM PANELS

After the unit is positioned, as shown in Figure 2, mark the

mounting position of the trim panels as follows:

1. Set the top (long) trim panel in place on top of the unit.

The panel should be flat against the outside face of the

fireplace, and standing vertically. Mark along the

lower edge of the trim panel with a pencil to make a

reference line for mounting.

2. Set the side trim panels in place behind and against the

intake covers, again, flat against the face of the

fireplace. Mark down the edge of the trim panel to

make a vertical reference line.
