Innovative Hearth Products
BRT40ST See-Through B-Vent Gas Fireplaces
These appliances comply with National Safety
Standards and are tested and listed by PFS
(Report No. 14-172) to ANSI Z21.50 (in
Canada, CSA-2.22), and CAN/CGA-2.17-M91,
latest editions, in both USA and Canada, as
vented gas fireplaces.
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, or the Natural Gas and Propane
Installation Code, CAN/CGA B149.1-latest edi-
tion. The appliance, when installed, must be
electrically grounded in accordance with local
codes or, in the absence of local codes, the
latest edition of the National Electrical Code,
ANSI/NFPA 70, or the Canadian Electrical Code,
CSA C22.1 - latest editions.
BTU Input
Millivolt Models -
The millivolt appliances are
manually controlled and feature a spark igniter
(piezo) that allows the appliance's pilot gas to
be lit without the use of matches or batteries.
This system provides continued service in the
event of a power outage.
Millivolt models come standard with a manually-
modulated gas valve; flame appearance and heat
output can be controlled at the gas valve. The BTU
Input for these appliances is shown in
Table 8.
In Canada - CAN/CGA-2.17-M91 (R2009)(high
altitude): THE CONVERSION SHALL BE CAR-
RIED OUT BY A MANUFACTURER’S AUTHO-
RIZED REPRESENTATIVE, IN ACCORDANCE
WITH THE REQUIREMENTS OF THE MANU-
FACTURER, 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 of 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.
A white film may develop on the glass front
during the first few fires as part of the curing
process. The glass should be kept clean during
the first two weeks of use to prevent the film from
baking on (making it very 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 "*" in
Table
)
. For
elevations above 4500 feet, contact your gas
supplier or qualified service technician.

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 pres-
sures
equal to or less than
1/2 psi (3.5 kPa).

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 or by 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.
Flame breadth, height and width will diminish
