in which the appliances are installed, through
openings not furnished with doors, are con-
sidered a part of the unconfined space.
• Do not install the appliance in a bedroom or
bathroom.
Serene Heat Gas Log appliances are certified by
OMNI-Test Laboratories to ANSI Z21.11.2 un-
vented room heaters standard. These gas log
appliances may be used as a space heat source
for a room in conjunction with an approved
unvented firebox.
• The installation must conform with local
codes or, in the absence of local codes with the
National Fuel Gas Code, ANSI Z223.1.

vice technician to inspect the appliance and to
replace any part of the control system and any
gas control which has been under water.
When local codes require the damper to be
fixed open, a damper stop must be installed to
prevent full closure of the fireplace damper
and provide a minimum 29 square inch flue
opening at all times.
1. Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3
(Include adjoining rooms with doorless pas-
sagewaysorventilationgrillsbetweenrooms.)
• Input ratings are shown in BTU per hour and
areforelevationsupto2,000feet.Donotinstall
this appliance at an elevation above 2,000 feet
unless the gas supply has been derated for that
elevation. Consult your local gas supplier. (If
thegassupplyhasnotbeenderated, theburner
orifice must be derated at the rate of 4% for
each 100 feet above sea level).
If damper clamp is not available, the damper
may be fixed open in the following manner.
Drill a hole in the end of the damper. Screw in
a bolt of sufficient size and adjust to provide the
minimum 29 square inches of flue opening.

• Ensure that the appliance is clean when
operating. Excessive dust accumulation on the
burner and/or logs will increase the amount of
carbon monoxide formation and could lead to
the formation of soot, carbon monoxide poi-
soning and sickness or death.
These heaters shall not be installed in a con-
fined space. The heater may be located in
unusually tight construction provided the
space is unconfined, or if confined, is pro-
vided with two permanent openings commu-
nicating directly with an additional room(s)
of sufficient volume so that the combined
volume of all connected spaces meets the
criteria for an unconfined space, (National
Fuel Gas Code ANSI Z223.1 (latest edition),
Section 5.3). Generally 50 ft 3 per 1,000 BTU
input of all operating appliances in the space.
Example: 3072 ft 3 / 50 ft 3 = 61.44
or 61,440 BTU/Hr the space can support.
3. Add the BTU/Hr of all the fuel burning appli-
ances in the space.

Gas Pressure Check
Do not burn solid fuels in any fireplace equipped
with this Dual-Listed gas appliance.
The appliance regulator controls the burner
pressure which should be checked at the pres-
suretestpoint(¹⁄₈"NPTpluggedtap)locatedon
the manual control valve body (on Manual
models) or on the control valve itself (on Milli-
volt models), identified OUT for the manifold
side and IN for inlet pressure (see Figure 8 ).
Ensure operating pressures are within the lim-
its specified in the technical chart on page 10.
An external regulator must be used on all
propane (L.P.G.) appliances, in addition to the
regulator fitted to the appliance, to reduce the
supply tank pressure to 13" w.c. (maximum).

A qualified gas appliance installer must install
this appliance.
Turn on gas supply and test for gas leaks,
using a gas leak test solution (also referred to
as bubble leak solution).
Check gas type: The gas supply must be the
same as stated on the appliance’s rating
plate. If the gas supply is different, DO NOT
INSTALL the appliance. Contact your dealer
for the correct model.
Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time.
Never use an open flame to check for leaks.
Step 1. Placement of Appliance – Center the
appliance in the fireplace or firebox. Make
certain the grate front feet sit inside the front
edge of the fireplace or firebox, and that there
is adequate clearance around the appliance for
access and operation.

OPERATION AND CARE OF YOUR
APPLIANCE
1. Appliance operation may be controlled
through the ON/OFF unit rocker switch, located
in the bottom front of the appliance, or through
a remotely located optional wall switch or wall
thermostat (Millivolt models only).
If, after a period of use, the flames start to
exhibit unusual shapes and behavior, if there
is any evidence of soot formation, blue tipping
of the flames, or any strong odors, or the
burners fail to ignite smoothly, then the burner
holes may require some cleaning. If this hap-
pens, it is preferable to contact your nearest
authorized service technician to get the appli-
ance serviced.
2. When lit for the first time, the appliance will
emit an odor for an hour or two. This is due to
the “burn-in” of the internal paints and lubri-
cants used in the manufacturing process. For
the first few hours, operate the appliance with
doors and windows open to encourage the
dissipation of odor.
