•  Your  fireplace  is  designed  to  be  used  in 

zero clearance installations. Wall or framing 
material can be placed directly against any 
exterior surface on the back, sides or top of 
your fireplace, except where standoff spac

-

ers are integrally attached. If standoff spac

-

ers  are  attached  to  your  fireplace,  these 
spacers can be placed directly against wall 
or framing material. See framing details on 
page 7.

•  If  you  plan  on  installing  a  television  or 

entertainment  center  recessed  above 
your fireplace, it is recommended that you 
maintain a minimum 18" above top of louver 
opening.

These are a few facts that can help you under

-

stand and enjoy your direct-vent fireplace:
•  The CD36R dedicated rear vent is best suited 

for flush or corner installations when vented 
horizontally through an exterior wall.

•  The  CD36T  dedicated  top  vent  is  suited 

for  any  application  where  height  is  nec

-

essary  to  terminate  the  venting  system 
either through the roof (vertical) or to gain 
sufficient  height  and  offset  to  vent  to  an 
outside/exterior wall (horizontal).

•  The vent pipe installation is very important 

to allow for proper operation. You must se

-

lect the appropriate unit for your application 
and follow the venting instructions to plan 
your installation.

•  This fireplace may be installed in any room 

of your house provided all local codes and 
these installation instructions are followed.

•  Models (V)CD36R/T are equipped with a 

millivolt gas control system that does not 
require electricity to operate. A piezo ignitor 
is provided to light the pilot without using 
matches or lighters.

•  Models (V)CD36RE/TE are equipped with 

an electronic ignition system that requires 
120VAC  to  operate. An  electrode  ignitor 
automatically  lights  the  pilot  flame  when 
the fireplace is turned on.

•  All models can accept an optional circulat

-

ing air blower when 120 VAC connection 
is supplied. If you plan to install an optional 
blower, do not forget to wire the fireplace 
outlet when framing.

•  Each time you turn on your fireplace, you 

may notice some amount of condensation 
on  the  inside  of  the  fireplace  glass. This 
is  normal  and  will  disappear  after  10-20 
minutes of operation. 

•  Your  direct-vent  gas  fireplace  system 

(fireplace and venting) is a balanced and 
sealed  gas  operating  unit.  It  is  highly 
efficient  because  it  uses  outside  air  for 
combustion  while  independently  heating 
the indoor air.

PRE-INSTALLATION PREPARATION

LOCATION AND SpACE 
REqUIREMENTS

Determine the safest and most efficient loca

-

tion for your DESA Heating, LLC direct-vent 
fireplace.  Make  sure  that  rafters  and  wall 
studs are not in the way of the venting system. 
Choose a location where the heat output is 
not affected by drafts, air conditioning ducts, 
windows or doors. Figure 2 shows some com

-

mon locations. Be aware of all restrictions and 
precautions before deciding the exact location 
for your fireplace and termination cap.
When deciding the location of your fireplace, 
follow these rules:
•  Do not connect this fireplace venting to a 

chimney flue serving a separate solid-fuel 
burning fireplace or appliance.

•  Due to high temperatures, do not locate this 

fireplace in high traffic areas, windy or drafty 
areas or near furniture or draperies.

•  Proper clearances must be maintained.
•  If your fireplace is to be installed directly on 

carpeting, vinyl tile or any combustible ma

-

terial other than wood, it must be installed 
on a metal or wood panel extending the full 
width and depth of the fireplace. See Figure 
3, page 6.
