PROPANE/LP GAS RESIDENTIAL HEATERS

®

For more information, visit www.desatech.com

 WARNING: Never install the

heater
• in a bedroom or a bathroom
• in a recreational vehicle
• where curtains, furniture,

clothing, or other flammable
objects are less than 36 inches
from the front, top, or sides of
the heater

• as a fireplace insert
• in high traffic areas
• in windy or drafty areas

IMPORTANT:

 Vent-free heaters add mois-

ture to the air. Although this is beneficial,
installing heater in rooms without enough
ventilation air may cause mildew to form from
too much moisture. See Fresh Air for Com-
bustion and Ventilation, 
pages 5 through 7.

INSTALLATION

CHECK GAS TYPE

Use only propane/LP gas. If your gas supply is
not propane/LP, do not install heater. Call
dealer where you bought heater for proper
type heater.

INSTALLATION ITEMS

Before installing heater, 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 *

• ground joint union

• test gauge connection *

• sediment trap

• tee joint

• pipe wrench

*  A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the optional CSA design-certified
equipment shutoff valve from your dealer.
See Accessories, page 23.

 WARNING: A qualified ser-

vice person must install heater.
Follow all local codes.

NOTICE: This heater is intended
for use as supplemental heat. Use
this heater along with your pri-
mary heating system. Do not in-
stall this heater as your primary
heat source. If you have a central
heating system, you may run
system’s circulating blower while
using heater. This will help circu-
late the heat throughout the
house. In the event of a power
outage, you can use this heater
as your primary heat source.

 CAUTION: This heater creates

warm air currents. These currents
move heat to wall surfaces next to
heater. Installing heater next to
vinyl or cloth wall coverings or
operating heater where impurities
(such as tobacco smoke, aromatic
candles, cleaning fluids, oil or
kerosene lamps, etc.) in the air
exist, may discolor walls.

LOCATING HEATER

You can locate heater on floor. The op-
tional hearth base is needed. You can also
install optional decorative mantels on the
heater (some mantels require the hearth
base).

 IMPORTANT:

 Only use optional

mantels and hearth base specified in this
manual. Purchase the optional mantel and
hearth base from your dealer. See Accesso-
ries
, page 23.

The heater may also be mounted on a wall.
You cannot use optional mantel if mounting
heater on a wall.

 WARNING: Maintain the mini-

mum clearances shown in Figure
9. If you can, provide greater clear-
ances from floor, ceiling, and join-
ing wall.

Figure 9 - Mounting Clearances As Viewed
From Front of Heater

For convenience and efficiency, install heater

• where there is easy access for operation,

inspection, and service.

• in coldest part of room.

An optional fan kit is available from your
dealer. See Accessories, page 23. If plan-
ning to use fan, locate heater near an electri-
cal outlet.

 CAUTION: If you install the

heater in a home garage
• heater pilot and burner must be

at least 18 inches above floor.

• locate heater where moving ve-

hicle will not hit it.
