Page Title
POWER VENT ONLY: This type is identied by the sux PV. This appliance draws all of its air for
combustion from outside the dwelling, through a Powered Exhaust. This appliance has been tested and
approved for installations from 0 feet to 4500 feet (1372 m) above sea level.
In the USA: The appliance may be installed at higher altitudes. Please refer to your American Gas Association
guidelines which state: the sea level rated input of Gas Designed Appliances installed at elevations above
2000 (610 m) feet is to be reduced 4% for each 1000 feet (305 m) above sea level. Refer also to local
authorities or codes which have jurisdiction in your area regarding the de-rate guidelines.
In Canada: When the appliance is installed at elevations above 4500 feet (1372 m), the certied high altitude
rating shall be reduced at the rate of 4% for each additional 1000 feet (305 m).
• This appliance has been tested by INTERTEK and found to comply with the established VENTED GAS
FIREPLACE HEATER standards in CANADA and the USA as follows:
VENTED GAS FIREPLACE HEATER (U33I-T NATURAL GAS, PROPANE GAS)
CERTIFIED TO: ANSI Z21.88 / CSA 2.33 VENTED GAS FIREPLACE HEATERS
CSA 2.17 GAS FIRED APPLIANCES FOR HIGH ALTITUDES
This Urbana Fireplace:
• Has been certied for use with either natural gas or propane (see rating label).
• Is not for use with solid fuels.
• Is approved for a bedroom or bed sitting room. (IN CANADA: must be installed with a listed wall thermostat.
IN USA: see current ANSI Z223.1 for installation instructions.)
• Must be installed in accordance with local codes. If none exist, use current installation code CAN/CGA B149.1
in Canada or ANSI Z223.1/NFPA 54 in the USA.
• Must be properly connected to an approved venting system and not connected to a chimney ue serving a
separate solid-fuel burning appliance.
IMPORTANT NOTICE (Regarding rst re up): When the unit is turned on for
the rst time, it should be turned onto high for the rst 4 hours. This will cure
the paint, logs, gasket material and other products used in the manufacturing
process. It is advisable to open a window or door, as the unit will start to smoke
and can irritate some people. After the unit has gone through the rst burn,
turn the unit o including the pilot, let the unit get cold then remove the glass
door and clean it with a good gas replace glass cleaner, available at your local
URBANA dealer.

Gas Supply Verication
Ensure the appliance is seeing correct gas pressures and
inputs. Verify the following information matches that of
the rating label. Pressure taps are located on the right
hand side of unit behind the screen. Remove the screen to
access the test taps. A 5/16 (8mm) I.D. hose is required to
make the connections. Check gas pressures as follows:
1. Open inlet pressure tap (half turn) and use
a manometer to verify inlet pressure with unit
running on HI. Pressure cannot exceed 1/2 PSIG
(14" W.C.) or valve damage may occur. Adjust inlet
pressure as needed and shut pressure tap.
NOTE: Do not spray leak-testing liquid in pressure taps or
results will not be accurate. r
2. Open pressure tap labelled "OUTLET" (half turn)
and connect manometer. Verify gas pressures are
within range while unit is running on HI and LO. Release
manometer and shut pressure tap. Contact your dealer
if proper pressures cannot be achieved.
Note - The replace must be isolated from the gas
supply piping system by closing its equipment shut-
o valve during any pressure testing of that system
at test pressures in excess of 1/2 psi (3.5 kPa).
