INSTRUCTIONS
INTRODUCTION
Before beginning the installation of your firebox, read these instruc-
tions through, completely.
These Comfort Glow components and fireboxes are safe when
installed according to this Installation Manual. Unless you use
Comfort Glow components which have been designed and tested for
the firebox system, you may cause a fire hazard.
The DESA International warranty will be voided by, and DESA
International disclaims any responsibility for the following actions:
a) Modification of the firebox, components, doors, blower fans,
air inlet system and damper control.
b) Use of any component part not manufactured or approved by
DESA International, in writing, in combination with a DESA
International firebox system.
Refer to your Homeowners guide for warranty information.

base of the firebox to the flue gas outlet, is 16 feet for a straight
chimney or with one elbow set. For systems with 2 elbow sets, the
minimum height is 30 feet. The maximum height of any system is 60
feet. This measurement includes the firebox, chimney sections and
the effective height of the termination assembly.

INSTALLING THE FIREBOX
STEP 1: Frame the opening for the firebox using the dimensions
shown in Figure 1 or Figure 2.
STEP 2: Set the firebox directly in front of this opening and slide the
unit back until the mounting flanges touch the side framing.
STEP 3: Check the level of the firebox and shim with sheet metal if
necessary.
STEP 4: When the firebox is installed upon a combustible floor a
galvanized steel ember protector (provided) must be installed be-
tween the firebox and the hearth extension as illustrated in Figures
12 and 13.
STEP 5: Secure the firebox to the framing through the flanges
located on the sides on the firebox with nails, or screws.
Note:
The 3/4" clearance is not required at the nailing flange. (see
Figure 10)
WARNING: Never use gasoline, gasoline-type lantern
fuel, kerosene, charcoal lighter fluid, or similar liq-
uids to start or “freshen up” a fire in this firebox. Keep

PROPER INSTALLATION is the most important step in ensuring
