HIGH ALTITUDE INSTALLATION
Your DESA Heating, LLC direct-vent fireplace
has been tested and approved in the USA for
elevations from 0-2000 feet (610 m) .
High altitude models as indicated by the letter
suffix (-HA) are equipped with specific gas
controls for installation above 4000 feet.
IMPORTANT: Fireplaces when factory
equipped for use at high altitude can not be
converted for use with propane/LP gas. When
installing a non-high altitude fireplace at an
elevation above 2000 feet (610 m) (in the
USA), you may need to decrease the input
rating by changing the existing burner orifice
to a smaller size. Reduce input 4% for each
1000 feet (305 m) above sea level. Check
with your local gas company for proper derate
procedure and orifice size.
Consult your local gas company to help deter-
mine the proper orifice for your location.
For assistance with any high altitude installation
call DESA Heating, LLC at 1-866-672-6040.

CHECK GAS TyPE
Use proper gas type for the fireplace unit you
are installing. If your gas supply is not correct,
do not install fireplace. See retailer where you
purchased the fireplace for proper fireplace
according to your gas type or to purchase gas
conversion kit (see Accessories, page 52).

WARNING: A qualified
Handset
service person must connect
fireplace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect fireplace
directly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between the
fireplace and propane/LP supply.
Installation Items Needed
Before installing fireplace, make sure you
have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas connec-
tor (if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the CSA design-certified equipment shutoff
valve from your retailer.
For propane/LP connection only, the installer must
supply an external regulator. The external regula-
tor will reduce incoming gas pressure. You must
reduce incoming gas pressure to between 11" and
14" of water. If you do not reduce incoming gas
pressure, fireplace regulator damage could occur.
Install external regulator with the vent pointing
down as shown in Figure 50, page 28. Pointing
vent down protects it from freezing rain or sleet.
