B-VENT GAS FIREPLACES • MODELS SLBV-35, SLBV-40 • CARE AND OPERATION INSTRUCTIONS
These appliances comply with National Safety
Standards and are tested and listed by ETL/
Intertek. (Report No. 100017854) to ANSI
Z21.50 (in Canada, CSA-2.22) and to CAN/
CGA-2.17-M91 in both USA and Canada (latest
editions at time of manual publication) as
vented gas fireplaces.
These appliances are listed by ETL/Intertek for
installation in bedrooms in the United States
(not approved in Canada)
The installation must conform to local codes
or, in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1/NFPA
54 - latest edition (In Canada, the current CAN/
CGA-B149.1 installation code).
The appliance, when installed, must be
electrically grounded and wired in accordance
with local codes or, in the absence of local
codes, with the USA National Electrical Code,
ANSI/NFPA 70 (latest edition) or, in Canada, the
Canadian Electrical Code, CSA C22.1 - latest
edition.
BTU Input
Millivolt and electronic models come standard
with a manually-modulated gas valve; flame
appearance and heat output can be controlled
at the gas valve. The BTU inputs for these ap-
pliances are shown in
Table 1.

IMPORTANT NOTE!
A white film may develop on the glass
enclosure panel during the first few
fires as part of the burn-in process.
The first few times you use the
fireplace, clean the glass after
each use (
AFTER THE GLASS HAS
COMPLETELY COOLED
); otherwise,
the white film will bake onto the
glass and become difficult to
remove.

Orifice Sizes
(Sea Level to High Altitude - All Models)
These appliances are tested and approved for
installation at elevations of 0 - 4500 feet (0 -
1372 meters) above sea level using the standard
burner orifice sizes (marked with an asterisk
(
*
) in
Table 4
).
For elevations above 4500 feet, contact your
gas supplier or a qualified service technician.
Deration
At higher elevations, the amount of BTU fuel
value delivered must be reduced by either:
• using gas that has been derated by the gas
company,
• changing the burner orifice to a smaller size
as regulated by the local authorities having
jurisdiction and by the (USA) National Fuel Gas
Code NFPA 54/ANSI Z223.1 - latest edition or,
in Canada, the CAN/CGA-B149.1 codes - latest
edition.
Install the appliance according to the regulations
of the local authorities having jurisdiction and,
in the USA, the National Fuel Gas Code NFPA
54 / ANSI Z223.1 - latest edition or, in Canada,
the CAN/CGA-B149.1 - latest edition.
NOTE: Flame appearance will diminish
4% per thousand feet of altitude.

Part /Cat. Number.
Test gauge connections are provided on the
front of the gas control valve, identified IN
for
the inlet and
OUT
for the manifold side (see
Figures 3 and 4
).
Propane tanks are at pressures that will cause
damage to valve components. Verify that the
tanks have step-down regulators to reduce the
pressure to safe levels.
The appliance and its appliance main gas
valve must be disconnected from the gas
supply piping system during any pressure
testing of that system at test pressures
in
excess of 1/2 psi (3.5 kPa).
The appliance must be isolated from
the gas supply piping system by closing
its equipment shutoff valve during any
pressure testing of the gas supply piping
system at test pressures
equal to or less
than 1/2 psi (3.5 kPa).
In Canada - CAN/CGA-2.17-M91 (R2009)
(high altitude):
THE CONVERSION SHALL BE CARRIED
OUT BY A MANUFACTURER’S AUTHO-
RIZED REPRESENTATIVE, IN ACCOR-
DANCE WITH THE REQUIREMENTS OF
THE MANUFACTURER, PROVINCIAL OR
TERRITORIAL AUTHORITIES HAVING
JURISDICTION AND IN ACCORDANCE
WITH THE REQUIREMENTS OF THE
CAN/CGA-B149.1 OR CAN/CGA-B149.2
INSTALLATION CODES.
Burn-in Period
During the first few fires
in this appliance there
will be some odor due to the curing of the
paint and burning off of lubricants used in the
manufacturing process. Depending on your
use, the burn-in period may take a few hours
or a few days.
KEEP YOUR HOUSE WELL VENTILATED
DURING THE CURING PROCESS. THE ODOR
AND HAZE EMITTED DURING THE CURING
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.
If an optional blower is installed, do not turn it
on during the burn-in period.
