WARNING
When used without adequate combustion and ventilation air,
heater may give off CARBON MONOXIDE, an odorless, poisonous
gas.
Do not install heater until all necessary provisions are
made for combustion and ventilation air. Consult the
written instructions provided with the heater for information
concerning combustion and ventilation air. In the absence of
instructions, refer to the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, Air for Combustion and Ventilation, or applicable
local codes.
This heater is equipped with a PILOT LIGHT SAFETY SYSTEM
designed to turn off the heater if not enough fresh air is
available.
DO NOT TAMPER WITH PILOT LIGHT SAFETY SYSTEM!
If heater shuts off, do not relight until you provide fresh air.
If heater keeps shutting off, have it serviced. Keep burner and
control compartment clean.
CARBON MONOXIDE POISONING MAY LEAD TO DEATH.
Early signs of carbon monoxide poisoning resemble the u, with
headache, dizziness and/or nausea. If you have these signs,
heater may not be working properly. Get fresh air at once! Have
heater serviced.
Some people – pregnant women, persons with heart or lung
disease, anemia, those under the inuence of alcohol, those
at high altitudes – are more affected by carbon monoxide than
others.
The pilot light safety system senses the depletion of oxygen at
its location. If this heater is installed in a structure having a high
vertical dimension, the possibility exists that the oxygen supply
at the higher levels will be less than that at the heater. In this type
of application, a fan to circulate the structure air will minimize
this effect. The use of this fan will also improve the comfort level
in the structure. When a fan is used to circulate air, it should be
located so that the air ow is not directed at the burner.

a gas leak.
Special care is required if you are installing the unit into
a sunken replace. You must raise the replace oor to
allow access to gas controls. This will insure adequate air
ow and guard against sooting. Raise the replace oor
using noncombustible materials.

• Do not try to light any appliance
• Do not touch any electrical switch; Do not use any
phone in your building
• Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the re depart-
ment.
C. Use only your hand to push in or turn the gas control
knob. Never use tools. If the knob will not push in or
turn by hand, don't try to repair it, call a qualied service
technician. Force or attempted repair may result in a re
or explosion.
