Installations at Altitudes of 0 to 4500 feet -
Units are tested and approved for elevations
of 0 to 4500 feet (0 to 1370 meters).
Installations at Altitudes above 4500 ft.-
For elevations above 4500 feet (1370
meters), install the unit according to the
regulations of the local authorities having
jurisdiction and, in the USA, the latest
edition of the National Fuel Gas Code (ANSI
Z223.1) or, in Canada, the latest edition of
the CAN-B149.1 and CAN-B149.2 codes.
Table 4 shows the units' gas orifi ce size for
the elevations indicated:
LOCATION
In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns. However, vent system routing to
the exterior and access to the fuel supply are
also important. Consideration should be given
to traffi c ways, furniture, draperies, etc., due
to elevated surface temperatures.
Considerations Should Include:
• Existing Chimneys
• Aesthetic Considerations
• Roof Design (Rafter Locations & Roof Pitch)
• Room Traffi c
• Proximity to Combustibles
• Proximity for Optimum Heat Transfer
• Electrical Wiring (if optional blower is
installed)
The installation of this stove will require some
research. Once your options are determined,
consult with your local building department
who will be able to give you the necessary
installation requirements for your area (Is
a building permit required?, Rooms where
installation may not be allowed?, etc.).

Ne pas se servir de cet appareil s'il a été
plongé dans l'eau, complètement ou en
partie. Appeler un technicien qualifi é pour
inspecter l'appareil et remplacer toute partie
du système de contrôle et toute commande
qui ont été plongés dans l'eau.
This appliance may be installed in an
aftermarket permanently located, manu-
factured home (USA only) or mobile
home, where not prohibited by local codes.
Cet appareil peut être installé dans un
maison préfabriquée (É.-U. seulement) ou
mobile déjà installée à demeure si les
réglements locaux le permettent.
Test gauge connections are provided on
the front of the millivolt gas control valve
(identifi ed IN for the inlet and OUT for the
manifold side).
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 in excess
of 1/2 psig (3.5 kPa).
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 must not be connected to
a chimney or fl ue serving a separate solid
fuel burning appliance.
WARNING: This appliance must be properly
connected to a venting system. Operation
of this gas appliance when not connected to
a properly installed and maintained venting
system can result in carbon monoxide (CO)
poisoning and possible death.
Carbon Monoxide Poisoning: Early signs
of carbon monoxide poisoning are similar
to the fl u with headaches, dizziness and/or
nausea. If you have these signs, obtain fresh
air immediately. Turn off the gas supply
to the appliance and have it serviced by
a qualifi ed professional, as it may not be
operating correctly.
The millivolt appliances are manually con-
trolled 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.
Do not use these appliances if any part
has been under water. Immediately call a
qualifi ed, professional service technician to
inspect the appliance and to replace any parts
of the control system and any gas controls
which have been under water.
