pRODUcT FEATURES

OPERATION

This vent-free fireplace insert is clean burning. It

requires no outside venting. There is no heat loss

out a vent or up a chimney. Heat is generated by

both realistic flames and glowing embers. When

used without the blower, the fireplace insert re-

quires no electricity making it ideal for emergency

backup heat.

SAFETY DEvICE

This fireplace insert 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 system shuts off the fire-

place insert if there is not enough fresh air.

PIEzO IGNITION SYSTEM

This fireplace insert has a piezo ignitor. This sys-

tem requires no matches, batteries or other sources

to light fireplace insert.

BLOWER ASSEMBLY

This fireplace insert is equipped with a blower

assembly. The blower operates thermostatically

and has a variable control. The blower circulates

heated air from the fireplace insert into the room.

Use of blower is optional.

AiR FOR cOMBUSTiON

AND VENTilATiON

WARNING: This heater shall

not be installed in a confined

space or unusually tight construc-

tion unless provisions are provid-

ed for adequate combustion and

ventilation air. Read the following

instructions to insure proper fresh

air for this and other fuel-burning

appliances in your home.

Today’s homes are built more energy efficient

than ever. New materials, 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 effi-

cient, 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.

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 fol-

lowing ventilation classifications:

1. Unusually Tight Construction

2. Unconfined Space

3. Confined Space

The information on pages 6 through 8 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 con-

struction where:
a. walls and ceilings exposed to the out-

side atmosphere have a continuous
water vapor retarder with a rating of
one perm (6 x 10

-11

kg per pa-sec-m

) or

less with openings gasketed or sealed
and

b. weather stripping has been added on

openable windows and doors and

c. caulking or sealants are applied to

areas such as joints around window
and door frames, between sole plates
and floors, between wall-ceiling joints,
between wall panels, at penetrations
for plumbing, electrical and gas lines
and at other openings.

If your home meets all of the three criteria
above, you must provide additional fresh
air. See Ventilation Air From Outdoors,
page 8.
If your home does not meet all of the three
criteria above, proceed to Determining
Fresh-Air Flow for Heater Location, page 7.
