Gas Pressure Requirements
(All Models)
Gas pressure requirements are listed in Tables
2 and 3.
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.

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.

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 BURN-IN PROCESS. THE ODOR
AND HAZE EMITTED DURING THE BURN-IN
PROCESS CAN BE QUITE NOTICEABLE AND
MAY SET OFF A SMOKE DETECTOR.
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.
See “Clean Glass Enclosure Panel”
on Page 10.
These appliances must be isolated
from the gas supply piping system (by
closing their individual manual shut-off
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).
These appliances and their individual
shut-off valves must be disconnected
from the gas supply piping system
during any pressure testing of that
system at pressures greater than 1/2
psig (3.5 kPa).
GENERAL INFORMATION
The fireplace models covered in this manual are
B-vented decorative gas appliances designed
for residential application.
Millivolt appliances have a millivolt gas control
valve with piezo ignition system.
Electronic appliances have a battery backed-up
electronic intermittent pilot system. No external
electrical power is required to operate these
appliances; however, 120 VAC is recommended
(see Installation Instructions).
These appliances comply with National Safety
Standards and are tested and listed by ITS
(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.
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 Instal-
lation Code, CAN/CSA B149.1 (latest edition).
The appliance, when installed, must be electri-
cally 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 Cana-
dian Electrical Code, CSA C22.1 (latest edition).

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, below).
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/CSA-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/CSA-B149.1 - latest edition.
NOTE: Flame appearance will diminish
4% per thousand feet of altitude.
