GENERAL INFORMATION
These Unvented Gas Log Room Heaters incor-
porate unitized ceramic fiber logs which glow
realistically when the heater is operating.
The log sets covered in this document are
manually controlled heater rated units. These
unitsareequippedwitheitherastandardmanual
gas valve or a millivolt gas valve. The control
knob is set to the desired position, which main-
tains a continuous gas burning rate.
A spark ignition system (piezo) allows the gas
pilot to be lit without the use of matches or
batteries and permits operation of the heater
during a power outage.
These heaters are fitted with a specially de-
signed pilot utilizing an oxygen depletion sen-
sor (ODS) which responds to the amount of
oxygen available in the room and shuts the
heater off before the oxygen level drops below
18%. The pilot can be relit only when fresh air
is available. Refer to the Combustion and Ven-
tilation Air section.

COMBUSTION AND VENTILATION AIR
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 3per 1,000 BTU
input of all operating appliances in the space.
The National Fuel Gas Code defines a con-
fined space as a space whose volume is less
than 50 ft 3per 1,000 BTU/Hr (4.8 m3per kw)
of the aggregate input rating of all appliances
installed in that space and an unconfined
space as a space whose volume is not less
than 50 ft 3per 1,000 BTU/Hr (4.8 m3per kw)
of the aggregate input rating of all appliances
installed in that space. Rooms communicat-
ing directly with the space in which the appli-
ances are installed, through openings not
furnishedwithdoors, areconsidered a partof
the unconfined space.
Unusually tight construction is defined as
construction where:
a. wall and ceilings exposed to the outside
atmosphere have a continuous water vapor
retarder with a rating or one perm or less with
openings gasketed or sealed, and
b. weather stripping has been added on oper-
able windows and doors, and
c.caulkingorsealantsareappliedtoareassuch
as joints around window and door frames,
between sole plates and floors, between wall-
ceiling joints, between wall panels, at penetra-
tions for plumbing, electrical, and gas lines,
and at other openings.
Use the following equations to determine if you
have a confined or unconfined space.
1. Determine the volume of space — ft 3.
Length x Width x Height = _____ ft 3
(Include adjoining rooms with doorless pas-
sageways or ventilation grills between
rooms.)
Example:24' (L)x16'(W)x 8'(H)= 3072ft 3
2. Divide the volume of space by 50 ft 3to
determine the maximum BTU/Hr the space
can support.
______ (volume of space – ft 3)/ 50 ft 3=
(Maximum BTU/Hr the space can support)
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.
Vent-Free heater _______ BTU/Hr
Gas appliance #1* _______ BTU/Hr
Gas appliance #2 + _______ BTU/Hr
Total = _______ BTU/Hr
Example:
Vent-free heater 32,000 BTU/Hr
Gas appliance #1 35,000 BTU/Hr
(water heater) Total = 67,000 BTU/Hr
* Do not include direct-vent gas appliances.
Direct-vent is sealed combustion and draws
combustion air from the outdoors.
4. Compare the maximum BTU/Hr the space
can support with the actual amount of BTU/
Hr used.

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. Refer to accessories for

Each heater includes a unitized set of ceramic
fiber logs. The heater and logs are assembled
as shown in Figure 11 . Handle these logs with
great care. The logs can be easily damaged, but
when handled properly they can provide years
of performance and enjoyment.
Gas Pressure Check
The heater regulator controls the burner pres-
sure which should be checked at the pressure
test point (¹⁄₈" NPT plugged tap) located at the
bottomof theregulator (onmanual models)or
on the control valve itself (on Millivolt mod-
els),identifiedA forthe manifoldsideand Efor
inlet pressure. Ensure operatilng pressures
are within the limits specified in the techinical
chart on page 10.

OPERATION AND CARE OF YOUR
APPLIANCE
1. Appliance operation may be controlled
through the ON/OFF unit rocker switch, located
in the control compartment, or through a re-
motely located optional wall switch or wall
thermostat.
2. Thermostat units are equipped with a two
stage (HI, LOW) gas control valve. To cycle the
burnerbetweentheHIandLOWsettings, rotate
the control knob clockwise and counterclock-
wise respectively.
3. When lit for the first time, the appliance will
emit a slight odor for an hour or two. This is
due to the “burn-in” of the internal paints and
lubricants used in the manufacturing process.
For the first few hours, operate the appliance
with doors and windows open to encourage
the dissipation of odor.
