GNOME
DIRECT VENT GAS HEATER

LIGHTING THE PILOT
STOP! Read the following safety information
before lighting.
This heater is equipped with an ignition device
which must be lighted by hand. When lighting the
pilot, follow these instructions exactly.
Before lighting, smell all around the appliance area
for gas. Be sure to smell next to the floor because
gas can be heavier than air and it will settle on the
floor.
IF
YOU
SMELL
GAS,
FOLLOW
INSTRUCTIONS
OUTLINED
AT
THE
BEGINNING OF THIS MANUAL!
Initial Burn, Fan, and Flame
The first time the heater is used, a paint odor will be
discernible. This odor is from the paint curing on
the outside of the heater. This is normal. The initial
flame will at first be blue. It will become more
yellow and “fire like.” Adjust the flame height
using the Hi/Lo flame adjust (see Figure 9). If flame
is low, turn the fan control to the lower setting. Do
not, however, turn the flame to “Hi” and leave the
fan control on the low speed. A good rule is high
flame, high fan and low flame, low fan.
Normal Sounds
A whisper sound from the pilot, upon start up,
might be audible, a clicking in the gas control valve,
and a whirring sound as the fan turns on: these
sounds are all normal.
WARNING: Do not burn heater if glass is cracked
or broken. See “Maintenance” for replacing glass.
MAINTENANCE
Make sure that there is adequate clearance for
accessibility to service and operate the heater.
Always verify proper operation after servicing.
Every year inspect the fire box, burner, and glass
gasket to make sure they are clean and functioning
properly.
WARNING: Failure to inspect and maintain the
heater may lead to improper burning inside the
heater and could create a dangerous situation.
Burner, Firebox, and Pilot Inspection
The firebox should be inspected for any soot or dust
build-up that might occur during operation. To
inspect these components, open the door by
unscrewing the handle until the door comes open.
Remove the logs gently and inspect the holes in the
burner plate to make sure that they are not clogged.
Inspect the metal for signs of deterioration. There
should be no soot in the firebox except where the
flame might brush against the logs. If soot is visible,
you contact your dealer or service technician for an
adjustment. Visually inspect the pilot for soot build-
up, proper flame height, and any obstruction. This
inspection should be done periodically to ensure
proper performance. See Figure 8 and Appendix B
for location of pilot.
Fan Cleaning
The fan should be cleaned at least once per season.
To do this remove the outer shield and vacuum the
squirrel cage fan blades. See Figure 12 for location
of fan.
Door Gasket
Make sure the door gasket is sealed and creates a
tight seal around the door.
