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 Input for these ap-

pliances are shown in Table 1.

Gas Pressure

Tables 2 and 3 show the appliances' gas

pressure requirements.

Test gauge connections are provided on the

front of the millivolt and electronic gas control

valve (identified IN for the inlet and OUT for the

manifold side). The control valves have a 3/8"

(10 mm) NPT thread inlet and outlet side of the

valve (refer to Figures 2 and 3).

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 dur-
ing any pressure testing of that system
at pressures greater than 1/2 psig (3.5
kPa).

Orifice Sizes - Sea Level to High Altitude

(All Models): These appliances are tested and

approved for installations at elevations of 0-4500

feet (0-1372 meters) above sea level using the

standard burner orifice sizes (marked with an

"*" in Table 4).

For higher elevations, contact your gas supplier

or qualified service technician.

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.

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/CSA-B149.1

- latest edition.

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.

If an optional blower is installed, Do Not turn

it on during the Burn-In period.

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).

See Cleaning Glass on Page 9.
