Maximum manifold pressure is 3.5 in. w.c.
(0.87 kPa) for natural gas and 10 in. w.c.
(2.49 kPa) for LP/Propane gas.
Installations at Altitudes of 0 to 4500 ft.-
Units are tested and approved for elevations
of 0 to 4500 feet (0 to 1372 meters).
Installations at Altitudes above 4500 ft.-
For elevations above 4500 feet (1372
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
CAN1-B149.1 and .2 codes.
Table 1 shows the units' gas orifice size for
the elevations indicated.

The millivolt appliances are manually controlled
and feature a spark ignitor (piezo) that allows
the appliance's pilot gas to be lit without the use
of matches or batteries. This system will still
function 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 con-
trol 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 may be installed as an OEM
installation in a manufactured home (USA
only) or mobile home and must be installed
in accordance with the manufacturer's in-
structions and the Manufactured Home Con-
struction and Safety Standard, Title 24 CPF,
Part 3280 or Standard for Installation in
Mobile Homes, CAN/CSA Z240 MH.
This appliance is only for use with the type(s)
of gas indicated on the rating plate. A con-
version kit is supplied with the appliance.
Cet appareil peut être installé comme du
matériel d'origine dans une maison
préfabriquée (É.-U. seulement) ou mobile
et doit être installé selon les instructions du
fabricant et conformément à la norme Manu-
factured Home Construction and Safety Stan-
dard, Title 24 CPF, Part 3280 ou à la norme
CAN/CSA Z240 Série MM, Maisons Mobiles.
Cet appareil doit être utilisé uniquement avec
les types de gaz indiqués sur la plaque
signalétique. Une trousse de conversion est
fournie avec l'appareil.
Test gage connections are provided on the
front of the millivolt gas control valve (iden-
tified IN for the inlet and OUT for the mani-
fold side).

Maximum inlet gas supply pressure to these appli-
ances is 10.5 inches water column (2.61 kPa) for
natural gas and 13.0 inches water column (3.23
kPa) for propane.
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 sys-
tem 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 test-
ing of that system at pressures in excess of ¹⁄₂
psig (3.5 kPa).
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 immediately. Turn off the gas supply to
the appliance and have it serviced by a
qualified professional, as it may not be op-
erating correctly.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
WARNING: FAILURE TO COMPLY WITH
THE INSTALLATION AND OPERATING IN-
STRUCTIONS PROVIDED IN THIS DOCU-
MENT WILL RESULT IN AN IMPROP-
ERLY INSTALLED AND OPERATING AP-
PLIANCE, VOIDING ITS WARRANTY.
ANY CHANGE TO THIS APPLIANCE AND/
OR ITS OPERATING CONTROLS IS DAN-
GEROUS. IMPROPER INSTALLATION
OR USE OF THIS APPLIANCE CAN CAUSE
SERIOUS INJURY OR DEATH FROM FIRE,
BURNS, EXPLOSION OR CARBON MON-
OXIDE POISONING.
WARNING: CHILDREN AND ADULTS
SHOULD BE ALERTED TO THE HAZARDS
OF HIGH SURFACE TEMPERATURES. USE
CAUTION AROUND THE APPLIANCE TO
AVOID BURNS OR CLOTHING IGNITION.
YOUNG CHILDREN SHOULD BE CARE-
FULLY SUPERVISED WHEN THEY ARE IN
THE SAME ROOM AS THE APPLIANCE.
WARNING: DO NOT PLACE CLOTHING
OR OTHER FLAMMABLE MATERIALS
ON OR NEAR THIS APPLIANCE.

ENFANTS. GARDER LES VÊTEMENTS,
LES MEUBLES, L'ESSENCE OU AUTRES
LIQUIDES À VAPEUR INFLAMMABLES
À COTE DE L'APPAREIL.

LOCATION

In selecting the location, the aesthetic and func-
tional use of the appliance are primary concerns.
However, vent system routing to the outside
atmosphere and access to the fuel supply are
also important. Consideration should be given to
traffic ways, furniture, draperies, etc., due to high
surface temperatures ( Figure 2 ). The location
should also be free of electrical, plumbing or
other heating/air conditioning ducting.
These direct vent appliances are uniquely suited
for installations requiring a utility shelf posi-
tioned directly above the fireplace. Utility shelves
like these are commonly used for locating
television sets and decorative plants.
To achieve the lowest possible shelf height, use
the alternative rear vent outlet. Do not insulate
the space between the appliance and the
area above it. See Figure 3 on page 4 . The
minimum height from the base of the appli-
ance to the underside of combustible materials
used to construct a utility shelf in this fashion is
shown in the table in Figure 3 on page 4 . The
weight of the utility shelf and anything placed
upon it may not be supported by the appliance
in anyway.
