first fire. It explains the controls and features of your
wood Fireplace Insert, how to choose firewood, burn
rates, and how to break-in your Fireplace Insert and
use it on a daily basis.
Controls & Features
WARNING: ONLY OPERATE WITH DOOR FULLY
OPEN OR CLOSED. IF DOORS ARE LEFT PARTLY
OPEN, GAS AND FLAME MAY BE DRAWN OUT OF
THE OPENING, CREATING RISKS FROM BOTH
FIRE AND SMOKE
IF OPERATING WITH DOORS FULLY OPEN, YOU
MUST USE THE ACCESSORY SCREEN AVAILIBLE
THROUGH YOUR HEARTHSTONE DEALER
If operating with the door open, some fuels may
create carbon monoxide, which can be hazardous or
fatal to your health. Do not burn anything but clean,
dry firewood
FRONT DOOR & LATCH:
The front door allows you
to load wood into your Fireplace Insert; a fixed handle
allows you to operate the front door and allows you to
latch the front door closed. The front door can be
reversed (hinges moved to the left) to open from the
right side. To open the door, lift the handle to the 10
o’clock (or 2 o’clock for RH opening door) position,
and pull out on the door. To latch the door, push the
door closed tightly then lower the handle to the 8
o’clock (4 o’clock for RH opening door) position. Pull
lightly on the door handle to ensure it is properly
latched.
PRIMARY AIR CONTROL:
The control handle is
located on the front top center of the ash lip under the
ash lip cover (see Figure 9). The primary air control
allows you to regulate the amount of air entering the
firebox. Generally, the more air allowed into the
firebox, the faster and hotter the rate of burn;
conversely, less air creates a slower burn. To fully
open the primary air intake, pull the handle as far out
as it will go away from the firebox; push the handle in
as far as it will go towards the firebox to close the
primary air control. The control does not completely
stop the flow of air.
Operating the Blower
The blower is pre-installed at the factory within the
front ash lip. The blower will run only when the insert
is hot. The blower control (notched wheel) is located
in the bottom center of the ash lip (see Figure 9). The
power cord can be routed to the left or right of the
insert - follow the instructions provided in the
installation section.

Choosing Firewood
Your Clydesdale Wood Burning Insert is designed to
only burn natural firewood - also known as cordwood.
CAUTION: DO NOT USE CHEMICALS OR
FLAMMABLE FLUIDS SUCH AS GASOLINE,
NAPHTHA, KEROSENE, CHARCOAL LIGHTER
FLUID OR ENGINE OIL TO START A FIRE. DO NOT
USE CHARCOAL, PELLETS, COAL, ARTIFICIAL
LOGS OR ANY OTHER MATERIALS AS FUEL;
THEY ARE NOT SAFE. DO NOT BURN GARBAGE.
The quality of your firewood affects heat output,
duration of burn and performance of your Fireplace
Insert. Softwoods generally burn hotter and faster,
while hardwoods burn longer and produce more long
lasting coals. Density and moisture content are two
