Electronic Models -
Electronic models have a manually modulated
gas valve. Input of electronic models is shown
in the following table:
These appliances are designed to operate on
natural or propane gas only. The use of other
fuels or combination of fuels will degrade
the performance of this system and may be
dangerous.
Millivolt Models -
Millivolt models come standard with the manu-
ally-modulated gas valve; flame appearance and
heat output can be controlled at the gas valve.
Input of millivolt models is shown in the fol-
lowing table:
Gas Pressure - All Models
Tables 3 and 4 show the appliances' inlet and
manifold gas pressure.

Table 4
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.
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).
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 (See Table 5). For elevations
above 4500 feet, 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
CAN1-B149.1 and .2 codes - latest edition.
Table 5 shows the gas orifice size required
for the elevations indicated.
WARNING
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 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 con-
tinued service in the event of a power outage.
Do not use these appliances if any part has
been under water. Immediately call a qualified,
professional service technician to inspect the
appliance and to replace any parts of the control
system and any gas control which have been
under water.
Ne pas se servir de cet appareil s'il a été plongé
dans l'eau, complètement ou en partie. Appeler
un technicien qualifié pour inspecter l'appareil et
remplacer toute partie du système de contrôle
et toute commande qui ont été plongés dans
l'eau.
This appliance is only for use with the type
of gas indicated on the rating plate. This
appliance is not convertible for use with
other gases, unless a certified kit is used.
Cet appareil doit être utilisé uniquement
avec les types de gaz indiqués sur la plaque
signalétique. Ne pas l'utiliser avec d'autres
gaz sauf si un kit de conversion certifié est
installé.
These appliances must not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.
Carbon Monoxide Poisoning: Early signs of
carbon monoxide poisoning are similar to the
flu with headaches, dizziness and/or nausea.
If you have these signs, obtain fresh air im-
mediately. Have the appliance serviced by a
qualified technician as it may not be operating
correctly. Some people are more affected by
carbon monoxide than others. These include
pregnant women, people with heart or lung
disease or anemia, those under the influence
of alcohol, and those at high altitudes.
