INTRODUCTION
These vented gas heaters are sealed combustion, air circulating gas stoves designed for
residential applications. These appliances
must be installed with "Security Secure
TM
Vent
" or "Simpson Dura Vent" brand vent
systems routed to the outside atmosphere
(other brands may not be used).
Millivolt appliances are designed to operate on natural or propane gas. A millivolt
gas control valve with piezo ignition system
provides safe, effi cient operation. External
electrical power is required to operate the
optional blower if installed on these units.
These appliances comply with National
Safety Standards and are tested and listed
by OMNI-Test Laboratories Inc.; Beaverton,
Oregon (Report No. 116-S-08-05) to ANSI
Z21.88-2002 (in Canada, CSA-2.33-2002),
and CAN/CGA-2.17-M91 in both USA and
Canada, as vented gas heaters.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Installation must conform to local codes. In
the absence of local codes, installation must
comply with the current National Fuel Gas
Code, ANSI Z223.1. (In Canada, the current
CAN-1 B149 installation code.) Electrical
wiring must comply with the National Electrical Code ANSI/ NFPA 70 - latest edition. In
Canada, the current CSA C22-1 Canadian
Electrical Code - latest edition.
DO NOT ATTEMPT TO ALTER OR MODIFY
THE CONSTRUCTION OF THE APPLIANCE OR ITS
COMPONENTS. ANY MODIFICATION OR ALTERATION MAY VOID THE WARRANTY, CERTIFICATION
AND LISTINGS OF THIS UNIT.
GENERAL INFORMATION
Note: Installation and repair should be per-
formed by a qualifi ed service person. The
appliance should be inspected annually by
a qualifi ed professional service technician.
More frequent inspections and cleanings may
be required due to excessive lint from carpeting, bedding material, etc. It is imperative
that the control compartment, burners and
circulating air passage ways of the appliance
be kept clean.
S'assurer que le brùleur et le compartiment
des commandes sont propres. Voir les
instructions d'installation et d'utilisation qui
accompagnent l'appareil.
Provide adequate clearances around air openings and adequate accessibility clearance for
service and proper operation. Never obstruct
the front openings of the appliance.
These appliances are designed to operate
on natural or propane gas only.
These millivolt models come standard with
the manually-modulated gas valve; fl ame
appearance and heat output can be controlled
at the gas valve.

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 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.
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, manufactured 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.
WARNING: FAILURE TO COMPLY WITH
THE INSTALLATION AND OPERATING
INSTRUCTIONS PROVIDED IN THIS DOCUMENT WILL RESULT IN AN IMPROPERLY
INSTALLED AND OPERATING APPLIANCE, VOIDING ITS WARRANTY. ANY
CHANGE TO THIS APPLIANCE AND/OR ITS
OPERATING CONTROLS IS DANGEROUS.
IMPROPER INSTALLATION OR USE OF
THIS APPLIANCE CAN CAUSE SERIOUS
INJURY OR DEATH FROM FIRE, BURNS,
EXPLOSION OR CARBON MONOXIDE
POISONING.

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.).

Code, State or Regional Gas Codes, National
Fuel Gas Code)
2. Local amendments
3. Recognized testing lab: OMNI-Test Laboratories Inc.; Beaverton, Oregon
4. Is a permit required - cost?
5. In some states or municipalities, a licensed
gas fi tter or plumber may be required to
install this appliance. Check with your local
building offi cial for requirements in your area
(i.e. Is a license required for installation of
gas supply line)?
6. Maximum amount of gas pipe without a
pressure test - type of test required?
7. Are below grade penetrations of the gas line
