Installation Instructions and Owner’s Manual
Unvented Natural Gas Vent Free Room Heaters
PRECAUTIONS:
1. An unvented room heater having an input rating of more
than 10,000 BTU (2931 W) (i.e. the HSSVFRD20NGBT,
HSSVFRD30NGBT, HSSVFBF20NGBT, and
HSSVFBF30NGBT) shall not be installed in a bedroom or
bathroom, or any place where a strong wind would shut
down the appliance.
2.
This heater needs outside ventilation air to run properly.
The Oxygen Depletion Sensor (ODS) safety shutoff
system shuts down the heater if not enough fresh air is
available. See Fresh Air for Combustion and Ventilation,
page 5.
3.
Keep all air openings in heater clear, free of debris or
any blockage. This will ensure that enough air for proper
combustion enters the heater.
4. If heater shuts off, do not relight until you provide fresh,
outside air. If heater keeps shutting off, it requires
servicing.
5. Turn off and let cool before servicing. Only a qualified
service person should service and repair heater.
**Operating heater above elevations of 4,500 feet could cause pilot/ODS to shutdown heater.**

6. Do not run heater:
•
Where flammable liquids or vapors are used or stored
•
During dusty conditions.
7. Before using furniture polish, wax, carpet cleaner or
similar products, turn heater off. If heated the vapors
from these products may create a white powder residue
within burner box or on adjacent walls or furniture.
8.
Do not use heater if any part has been underwater.
Immediately call a qualified service technician to inspect
the room heater and to replace any part of the control
system and any gas control which has been underwater.
9.
Operating heater above elevations of 4,500 feet
could cause pilot/ODS to shutdown heater.
DANGER:
Carbon monoxide poisoning may lead to death.
Carbon Monoxide Poisoning:
Early signs of carbon monoxide poisoning resemble the
flu, with headaches, dizziness, or nausea. If you have these
signs, the heater may not be working properly. Get fresh
air at once! Have heater serviced. Some people are more
affected by carbon monoxide than others. These include
pregnant women, persons with heart or lung disease or
anemia, those under the influence of alcohol, and those at
high altitudes.
Natural Gas:
Natural gas is odorless. An odor making agent is added to
natural gas. The odor helps you detect a natural gas leak.
However, the odor added to the gas can fade. Gas may
be present even though no odor exists. Make certain you
read and understand all warnings. Keep this manual for
reference. It is your guide to safe and proper operation of
this heater.
