NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
Electronic Models -
Electronic models have a fixed rate gas valve.
Input of electronic models is shown in the
following table:
Input of millivolt models is shown in the fol-
lowing table:
All Models -
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.
Table 1
Millivolt Models -
Millivolt models come standard with the
manually-modulated gas valve; flame ap-
pearance and heat output can be con-
trolled at the gas valve.
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'lau.
This appliance may be installed in an after-
market permanently located, manufactured
home (USA only) or mobile home, where not
prohibited by local codes. This appliance is
only for use with the type of gas indicated
on the rating plate. This appliance is not con-
vertible for use with other gases, unless a
certified kit is used.
Cet appareil peut être installé dans un
maison préfabriquée (É.-U. seulement) ou
mobile déjà installée à demeure si les
réglements locaux le permettent.
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.
Millivolt appliances may be fitted at time of
manufacture with either a Honeywell millivolt
gas control valve or as SIT millivolt gas control
valve. Both valves have been tested with and
approved for use with these appliances and
are listed accordingly.
Test gage connections are provided on the
front of the millivolt gas control valves (iden-
tified OUT for the manifold side and IN for inlet
pressure side for both SIT and Honeywell
equipped appliances. A
¹⁄₈
" NPT test gage
connection is provided on the electronic gas
control valve adjacent to the outlet to the main
burner.
Minimum inlet gas pressure to the appliance is
5.0 inches water column (1.24 kPa) for natural
gas and 11 inches water column (2.74 kPa) for
propane for the purpose of input adjustment.
Maximum inlet gas supply pressure to the
appliance is 10.5 inches water column
(2.61kPa) for natural gas and 13.0 inches
water column (3.23 kPa) for propane.
The appliance must be isolated from the gas
supply piping system (by closing its individual
manual shut-off valve) during any pressure test-
ing of the gas supply piping system at test
pressures equal to or less than
¹⁄₂
psig (3.5) kPa).
The appliance and its individual shut-off valve
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 not be connected to a
chimney or flue serving a separate solid fuel
burning appliance.
Do not place clothing or other materials on or
near this 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 immedi-
ately. Turn off the gas supply to the appliance
and have it serviced by a qualified profes-
sional, as it may not be operating correctly.
WARNING: B-VENT APPLIANCES ARE
NOT DESIGNED TO OPERATE IN NEGA-
TIVELY PRESSURED ENVIRONMENTS
(PRESSURE WITHIN THE HOME IS LESS
THAN PRESSURES OUTSIDE). SIGNIFI-
CANT NEGATIVELY PRESSURED ENVI-
RONMENTS CAUSED BY WEATHER,
HOME DESIGN, OR OTHER DEVICES MAY
IMPACT THE OPERATION OF THESE AP-
PLIANCES. NEGATIVE PRESSURES MAY
RESULT IN POOR FLAME APPEARANCE,
SOOTING, DAMAGE TO PROPERTY AND/
OR SEVERE PERSONAL INJURY. DO NOT
OPERATE THESE APPLIANCES IN NEGA-
TIVELY PRESSURED ENVIRONMENTS.
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 DANGER-
OUS. IMPROPER INSTALLATION OR
USE OF THIS APPLIANCE CAN CAUSE
SERIOUS INJURY OR DEATH FORM FIRE,
BURNS, EXPLOSION OR CARBON MON-
OXIDE POISONING.
