AIR FOR COMBUSTION AND
VENTILATION
Today’s homes are built more energy efficient than ever. New mate-
rials, increased insulation, and new construction methods help reduce
heat loss in homes. Home owners weather strip and caulk around
windows and doors to keep the cold air out and the warm air in. During
heating months, home owners want their homes as airtight as possible.
While it is good to make your home energy efficient, your home
needs to breathe. Fresh air must enter your home. All fuel-burning
appliances need fresh air for proper combustion and ventilation.
Exhaust fans, fireplaces, clothes dryers, and fuel burning appliances
draw air from the house to operate. You must provide adequate fresh
air for these appliances. This will insure proper venting of vented
fuel-burning appliances.
WARNING: This heater shall not be installed in a
confined space or unusually tight construction un-
less provisions are provided for adequate combus-
tion and ventilation air. Read the following instruc-
tions to insure proper fresh air for this and other fuel-
burning appliances in your home.
PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code, ANSI
Z223.1/NFPA 54, Section 5.3, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation
classifications:
1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space
The information on pages 4 through 6 will help you classify your
space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough
fresh air for combustion and ventilation. However, in buildings of
unusually tight construction, you must provide additional fresh air.
Unusually tight construction is defined as construction
where:
a. walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating
of one perm (6 x 10
-11
kg per pa-sec-m
2
) or less with
openings gasketed or sealed
and
b. weather stripping has been added on openable win-
dows and doors
and
PRODUCT FEATURES
OPERATION
This heater is clean burning. It requires no outside venting. There is no
heat loss out a vent or up a chimney. Heat is generated by realistic
flames. This heater is designed for vent-free operation with flue damper
closed. It has been tested and approved to ANSI Z21.11.2 standard for
unvented heaters. State and local codes in some areas prohibit the use
of vent-free heaters. This heater may also be operated as a vented
decorative (ANSI Z21.60) product by opening the flue damper.
SAFETY DEVICE
This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety
shutoff system. The ODS/pilot is a required feature for vent-free room
heaters. The ODS/pilot shuts off the heater if there is not enough fresh air.
PIEZO IGNITION SYSTEM
This heater has a piezo ignitor. This system requires no matches,
batteries, or other sources to light heater.
