Table 1
Test gage connections are provided on the
front of the millivolt gas control valve (identi-
fied IN for the inlet and OUT for the manifold
side). A 1/8" NPT test gage connection is
provided at the inlet and outlet side of
the electronic gas control valve.
Minimum inlet gas pressure to these appliances
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 these
appliances is 10.5 inches water column (2.61
kPa) for natural gas and 13.0 inches water
column (3.23 kPa) for propane.
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.
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 provides
continued service in the event of a power outage.
These appliances must be isolated from the gas
supply piping system (by closing their individual
manual shut-off valve) during any pressure test-
ing of the gas supply piping system at test pres-
sures 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 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.
These heater rated appliances are intended
for use as supplemental heaters only.
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.
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.
Electronic Models -
Electronic models have a fixed rate gas valve.
Input of electronic models is shown in the
following 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.
Table 1
shows the units' gas orifice size for
the elevations indicated.
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 appli-
ance is only for use with the type of gas
indicated on the rating plate. This appli-
ance is not convertible 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.
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.
Input of millivolt models is shown in the
following table:
