Heater Installation - New Buck Corporation 20 Room Heater Installation And Operation Manual

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 birds' nest. If the chimney is excessively dirty, clean it, or have someone clean it
professionally BEFORE installing or using the room heater.
6. The Firebrick, Ash Lip, Smoke Baffle, and Smoke Shelf may also be removed if necessary to provide room
for the Model 20.
CAUTION: Any parts removed from the Pre-Fab Fireplace must be stored inside the unit or given to the
homeowner for re-installation should the Model 20 be removed.
Heater Preparation
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 that it will open and close properly.

Heater Installation

1. There are three listed and tested methods of installation of the Model 20 heater into the specified Pre-Fab
Models.
A. 6" Increaser
1. The preferred method is to use an increaser made of 24 ga. (minimum) stainless steel to go from 6"
inside diameter to the exact diameter of the fireplace throat/chimney. (See Figure 2.)
2. Position the increaser into the throat/chimney of the Pre-Fab Cabinet at a height slightly higher than
the Model 20 will be after installation (22" + above Pre-Fab heater supports). NOTE: The increaser may
be a two part slip connector type if desired.
B. Ceramic Blanket
1. The second method is to use a 6" stainless steel connector (rigid or flex) and a ceramic blanket
(available from your dealer). (See Figure 3.)
2. Cut the connector at least 18" long and tightly wrap the upper portion of the connector with the
ceramic blanket to almost the size of the fireplace throat/chimney.
3. Insert the connector into the fireplace throat/chimney and use additional ceramic insulation and tightly
pack around the connector and the throat/chimney at a height slightly higher than the Model 20 will be
after installation (22" + above Pre-Fab heater supports). NOTE: The increaser may be a two part size
connector type if desired.
