Purge all gas lines with the glass door of the fireplace open.
Assure that a continuous gas flow is at the burner before
closing the door.
Under extreme vent configurations, allow several minutes
(5-15) for the flame to stabilize after ignition.
Eight (8") inches is the minimum bend radius allowed for
the 7" diameter flexible air liner.
Provide adequate ventilation and combustion air. Provide
adequate accessibility clearance for servicing and operat-
ing the fireplace. Never obstruct the front opening of the
fireplace.
Objects placed in front of the fireplace must be kept a
minimum of 48" from the front face of the unit.
Minimum clearance to combustible construction
from fireplace and vent surfaces:
fireplace framing - 0" to stand-offs (top, rear and sides)
fireplace finishing - 3" to sides, 7¼" to top of unit
vent pipe
- 2 inches *
recessed depth - 16 inches

FOR YOUR SATISFACTION, THIS FIREPLACE HAS BEEN
TEST-FIRED TO ASSURE ITS OPERATION AND QUALITY!
Maximum input is 35,000 BTU/hr for natural gas and 33,000
BTU/hr for propane. When the fireplace is installed at eleva-
tions above 4,500ft, and in the absense of specific recom-
mendations from the local authority having jurisdiction, the
certified high altitude input rating shall be reduced at the rate
of 4% for each additional 1,000ft. Maximum output for natural
gas is 28,350 BTU/hr at an efficiency of 81%; and 26,400 BTU/
hr for propane at an efficiency of 80%. Minimum A.F.U.E. rating
is 64% for natural gas and 65% for propane. Minimum inlet
gas supply pressure is 4.5 inches water column for natural
gas and 11 inches water column for propane. Maximum inlet
gas pressure is 7 inches water column for natural gas and 13
inches water column for propane. Manifold pressure under
flow conditions is 3.5 inches water column for natural gas
and 10 inches water column for propane.
This fireplace is approved for bathroom, bedroom and bed-
sitting room installations and is suitable for mobile home
installation. The natural gas model can only be installed in
a mobile home that is permanently positioned on its site
and fueled with natural gas.
WARNING: The door for this fireplace is sold
separately. The door must be installed and
closed before operation begins. Refer to
"DOOR INSTALLATION" under the "FINISH-
ING" Section for details.
FIGURE 1
THIS GAS FIREPLACE SHOULD BE INSTALLED AND
SERVICED BY A QUALIFIED INSTALLER to conform with
local codes. Installation practices vary from region to re-
gion and it is important to know the specifics that apply to
your area,
for example: in Massachusetts State:
• The fireplace damper must be removed or welded in the
open position prior to installation of a fireplace insert or
gas log.
• The appliance off valve must be a “T” handle gas cock.
• The flexible connector must not be longer than 36 inches.
• The appliance is not approved for installation in a
bedroom or bathroom unless the unit is a direct vent
sealed combustion product.
• WARNING: This product must be installed by a licensed
plumber or gas fitter when installed within the
commonwealth of Massachusetts.
In absence of local codes, install to the current CAN/CGA -
B149 Installation Code in Canada or to the National Fuel
Gas Code, ANSI Z223.1, and NFPA 54 in the United States.
Suitable for mobile home installation if installed in accor-
dance with the current standard CAN/CSA Z240MH Series,
for gas equipped mobile homes, in Canada or ANSI Z223.1
and NFPA 54 in the United States.
The fireplace and its individual shutoff valve must be discon-
nected from the gas supply piping system during any pressure
testing of that system at test pressures in excess of 1/2 psig
(3.5 kPa). The fireplace must be isolated from the gas supply
piping system by closing its individual manual shutoff valve
during any pressure testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig (3.5 kPa).
When the fireplace is installed directly on carpeting, vinyl tile or
other combustible material other than wood flooring, the fire-
place shall be installed on a metal or wood panel extending
the full width and depth.
The optional heat circulating blower is supplied with a cord. If
installed, the junction box must be electrically connected and
grounded in accordance with local codes. In the absence of
local codes, use the current CSA C22.1 CANADIAN ELECTRI-
CAL CODE in Canada or the ANSI/NFPA 70 NATIONAL ELEC-
TRICAL CODE in the United States.
